Answer: Red dwarfs
Explanation:
Red dwarfs are thought to be the coolest star out of the rest. They are also the smallest. Because they are so cool, their luminosity is low as well on account of the fact that relatively speaking, the fusion taking place on their surface is little.
Red dwarfs are the most numerous star in the universe and the most numerous in the Milky Way galaxy as well. We just can't see them with out naked eyes because of their low luminosities.
In 1980 there was growing concern that the protective ozone layer over the Antarctic might be decreasing and thereby allowing so much harmful ultraviolet radiation to reach the Earth that polar marine life would be damaged. Some government officials dismissed these concerns, since statistics indicated that global atmospheric ozone levels remained constant. The relevance of the evidence cited by the government officials in support of their position would be most seriously undermined if it were true that
Answer:
Even where the amount of atmospheric ozone is normal, some ultraviolet light reaches the Earth's Surface.
Explanation:
Before 1980 there was very little concern about atmospheric ozone decrease. Many plants and animals flourish in warm climates rather than in polar regions. The increase exposure to ultraviolet rays due to shift in atmospheric ozone has threatened marine life.

Imagine that an impact occurred on the continental plate millions and millions of years ago, leaving behind an impact crater near the right side of the base of the volcano. Why would there be little evidence of this impact crater found today
Answer:
erosion would erode the surrounding area making less obvious and filled in by hardened magma leaving volcano over millions of years i think. Would leave little impact of the crater. Also growth of plants over years in ash-rich, fertile soil
Explanation:
Volcanic craters may be connected with a cone or flanks. Flows may also be present. Impact craters can be distinguished from volcanic craters by having center peaks, ejecta, high rims, and floors that are lower in elevation than the surrounding topography.
What is a volcanic crater called?A caldera is a depression formed when a volcano's magma chamber is emptied in an explosive eruption. Without any structural support below, the terrain surrounding the erupting volcanic vent or vents collapses internally, forming the bowl-shaped caldera.
When an asteroid or meteorite collides with the surface of a bigger solid object, such as a planet or moon, an impact crater is generated. This item must be moving extremely fast—many thousands of miles per hour—in order to generate a proper impact crater.

Why do we see different shapes of moon ?
Answer:
The phases change as the moon revolves around Earth, different portions of the moon's sunlit surface are visible from Earth. Thus, from the perspective of Earth, the appearance of the moon changes from night to night. Not only does the apparent shape of the moon change, its position in the sky also changes.

3. Differentiate between. a) Igneous and sedimentary rock b) Sedimentary and metamorphic rock 4. Classify the following rocks Marble, Pumice, Slate, Obsidian, Limestone 5. Write answer in brief a) What is rock? b) How are igneous rocks formed? c) What type of rock is called sedimentary rock? d) Which rock consists of fossils? e) How are metamorphic rocks formed? Give example also. 6. Write any four uses of rocks.
Answer:
3.igneous and sedimentary and sedimentary and metamorphic.
4. Marble- metamorphic
pumice-igneous
slate- metamorphic
obsidian- igneous
limestone-sedimentary
5. a) A rock is a solid mass of geological materials. Geological materials include individual mineral crystals, inorganic non-mineral solids like glass, pieces broken from other rocks, and even fossils. A rock can be composed of only one type of geological material or mineral, but many are composed of several types.
b) Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.
c) Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter).
d) sedimentary rock consits of fossils.
e) Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
6. Any four uses of rocks are:
•Making Cement (Limestone) (Sedimentary Origin)
•Writing (Chalk) (Sedimentary Origin)
•Building Material (Sandstone) (Sedimentary Origin)
•Bath Scrub (Pumice) (Igneous Origin)
•Kerb Stone (Granite) (Igneous Origin)

How does the hydrolysis process work in chemical weathering?
A. Chemicals in rock and soil are exposed by water and wind.
B. Water fills crevices in rocks and soil and erodes them.
C. Chemicals interact with frozen water to thaw it.
D. Water mixes with other elements to create chemicals.
Answer: answer is D
Explanation: Because in the hydrolysis process it involves the mixture of two or more substances , and is the breakdown of a substance when combined with water chemically.
HOPE THIS HELPS!!!!
The hydrolysis process works in chemical weathering and involves Water mixed with other elements to create chemicals. Thus the correct answer is D.
What is chemical weathering?When molecules in rainwater and running water mix with minerals and rocks, it is called chemical weathering, and the result is a modification or degradation of the rocks and minerals.
Weathering can result from a response between rainwater and the elements in the rock. The greatest example of chemical weathering is when iron corrodes because of oxidation.
A compound is typically dissolved during hydrolysis, which is the combination of an organic molecule with water to generate two or more new compounds. It will be illustrated via the transformation of cellulose into glucose units.
Therefore, option D Water mixes with other elements to create chemicals is appropriate.

Which layer of Earth experiences the least amount of pressure?
Answer: the crust.
Explanation: Because the crust does not have to support as much weight. For example, if you were to say the layer closest to the center of the Earth experiences the least amount of pressure, that would not be true because the layers closer to the center of the Earth have to support even more weight above them then the layer farthest out.

why fossils are found in sedimentary rocks
give answer for grade 7
Answer:
Almost all fossils are preserved in sedimentary rock. Organisms that live in topographically low places (such as lakes or ocean basins) have the best chance of being preserved. This is because they are already in locations where sediment is likely to bury them and shelter them from scavengers and decay.

This map shows the location of the Sumatra Earthquake of 2004 and the aftershocks.
What is most likely inferred about the aftershocks, based on this map?
A. They were mainly large and some could be considered earthquakes on their own.
B. They were felt for many weeks after the original earthquake.
C. They were concentrated in one area of the Indian Ocean.
D. They were mainly small and unable to be felt by most people.
Answer:
Earthquakes occur in the crust or upper mantle, which ranges from the earth's surface to about 800 kilometers deep (about 500 miles).
The strength of shaking from an earthquake diminishes with increasing distance from the earthquake's source, so the strength of shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.
Also, the depths of earthquakes gives us important information about the Earth's structure and the tectonic setting where the earthquakes are occurring. The most prominent example of this is in subduction zones, where plates are colliding and one plate is being subducted beneath another. By carefully plotting the location and depth of earthquakes associated with a subduction zone, we can see details of the zone's structure, such as how steeply it is dipping, and if the down-going plate is planar or is bending. These details are important because they give us insight into the mechanics and characteristics of the deformation in the subduction zone.
Within continents, and along continental plate boundary transform faults such as the San Andreas, faults are only active in the shallow crust - perhaps to depths of approximately 20 km.
Accurately determining the depth of an earthquake is typically more challenging than determining its location, unless there happens to be a seismic station close and above the epicenter. So generally, errors on depth determinations are somewhat greater than on location determinations.
Answer:
B. They were felt for many weeks after the original earthquake

Explain how species within the natural environment work together.
Answer:
This happens by the process of natural selection. By natural selection, the nature of the species gradually changes to become adapted to the niche. If a species becomes very well adapted to its environment, and if the environment does not change, species can exist for a very long time before they become extinct.
The ones that will be discussed in this article are competition, predation, herbivory and symbiosis. These are not the only types of species interactions, just the most studied — and they are all parts of a larger network of interactions that make up the complex relationships occurring in nature.

In a paragraph of not more than 8 lines describe the reasons for the difference in the population density of South Africa and England.
Hey there! I'm happy to help!
Both South Africa and England have a similar populations. However, these countries have different population densities. Population density is how crowded the country is with people. South Africa is a much larger country in terms of its area while England has a smaller land area. If they have similar populations, but different amounts of space, one is going to have a higher population density. Since England has less space, it has a higher population density as there are more people in a smaller space. There is more land area in South Africa, so this naturally makes it less crowded.

please help! giving away 10 points.
The definition of spatial is: relating to or using space.
Geospatial data is time-based data that is related to a specific location on the Earth's surface. It can provide insights into relationships between variables and reveal patterns and trends.
A spatial pattern is an intuitive structure, placement, or arrangement of objects on Earth. It also includes the space in between those objects. Patterns may be recognized because of their arrangement; maybe in a line or by a grouping of points.
Spatial modeling is an analytical process managed with a geographical information system (GIS) in order to describe basic processes and properties for a given set of spatial features.

identify the statement that is true about soil-forming factors. a. Dry soils tend to contain more organic material than wet soils contain, because wet soils drown vegetation. b. Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed. c. Soil that forms on basalt bedrock will be the same as soil formed on granite bedrock because they are both igneous bedrocks. d. Soil that forms on steep slopes is thicker than soil formed on flat land because of the accumulation of sediment on slopes.
Answer: b. Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed.
Explanation:
Some plants require more a of particular nutrient than others and so will draw more of these nutrients from the soil whilst giving away some of the ones that they do not want. This is one of the reasons that some plants grow better in a particular area than not.
When these plants give or take away nutrients, they would be changing the type of nutrient composition of the soil and this is what makes crop rotation so effective.

When there is competition for land, what are some things stakeholders can do to have their voices heard?
Housing development is a solution to increasing housing demand with the rise in population, but this cannot be achieved without causing various environmental impacts. If you lived in Georgia, would you want this land to be developed or preserved? Why?
The land should not be developed.
The stakeholders can do shutdown their businesses and stop doing business activities to have their voices heard. This piece of land should not be developed, it can be preserved because this is the only land left where the organisms live.
If this land is also developed, then the extinction of animals occurs and the whole biodiversity is eliminated from that area so in my opinion, the land should be preserved for the animals so it is recommended that the land should not be developed.
