Answer:
The Earth, Sun, and Moon
The Earth
Earth, which is our base from which we look into space, is constantly moving. Understanding this movement is one of the most useful and important things in astronomy.
The earth orbits the sun in an elliptical orbit and the moon orbits the earth with the same kind of orbit. Looking down from the north pole, the earth spins in a counterclockwise direction on an imaginary line called its axis once every day. This accounts for the fact that the sun rises in the east and sets in the west. The earth’s axis is tilted with respect to the plane of its orbit at an angle of about 23.4 degrees. If we position ourselves high above the north pole, we would see that the earth orbits the sun in a counterclockwise motion, coming to the same position among the stars every 365.26 earth days. We would also see that the moon also orbits the earth in a counterclockwise motion. This is illustrated in the following example.
Figure 1: The directions of the orbits of the earth and moon.
The average distance from the earth to the sun, the semimajor axis of its orbit, is 149,597,890 km. This distance was not known until recently and it is called the astronomical unit or AU. The distances of the other planets to the sun are usually measured in astronomical units.
Because of the tilt of the earth, not every place on earth gets light every day. Also, some places have extremely short days.
As the earth revolves around the sun, the place where light shines the brightest changes. This motion gives us the different seasons. For instance, the poles receive less light than does the equator because of the angle that the land around the poles receive the sun’s light. When the north pole is tilted toward the sun, the northern hemisphere is presented to the sun at a greater angle than the southern hemisphere and the northern hemisphere gets warmer. When this happens, the northern hemisphere gets summer while the southern hemisphere gets winter. When the south pole is tilted toward the sun, the two seasons reverse hemispheres. This is illustrated in the following image.

2 List five different environments you know
Answer:
Forests, grasslands, deserts, tundra, freshwater, and marine.
Explanation:
Answer:
Five different environments are the forest, desert, grasslands, freshwater, and mountains.
Explanation:
A forest environment is a complex ecosystem consisting mainly of trees that buffer the earth and support a myriad of life forms. The trees help create a special environment which, in turn, affects the kinds of animals and plants that can exist in the forest. Plants provide habitat to different types of organisms.Desert environments are extremely dry environments that are home to well-adapted plants and animals. The main types of deserts include hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts.Grassland environments are areas in which the vegetation is dominated by a nearly continuous cover of grasses. Grasslands occur in environments conducive to the growth of this plant cover but not to that of taller plants, particularly trees and shrubs. Freshwater environments are defined as having a low salt concentration — usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e., ocean). There are different types of freshwater regions, such as ponds, lakes, rivers, streams, and wetlands.Mountain environments are made up of complex living organisms in mountainous areas. Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, or tundra.Which letter in this diagram represents evaporation?
A
B
C
D
Answer: The Answer is A
Explanation: Because that cycle shows the process of evaporation .
The salt Intrusion is being condensed to water vapour through heat from the sun.
HOPE THIS HELPS!!!!
Evaporation is the process that allows a liquid to change of phase to a gas phase or vapor.
We will see that the correct option is A.
In the image we can see the cycle of water, we know that roughly it works as:
Water liquid.Water evaporates and goes to the clouds.Rain makes the water come down to the Earth.Finally, that water comes again to the larger masses of water.So looking at the image, we can see that the point that represents the evaporation of water is point A, where we have arrows that show the direction that water takes, meaning that it goes from the liquid to the clouds (goes from liquid to gas)

Which part of Africa was most affected by the slave trade?
Answer:
West Central Africa
Explanation:
The majority of all people enslaved in the New World came from West Central Africa.
Aquifers are made up of gravel and sand characterized by holes and channels, like the pores of a sponge. They hold water that has accumulated over thousands of years. The water moves through the pores of the aquifer rock very slowly. Using this information, what can you predict about our ability to clean up aquifers polluted by pesticides, herbicides, and other toxic chemicals
Answer:
It turns really difficult -and expensive- to clean or revert the situation of a polluted aquifer, if not impossible.
Explanation:
Once an aquifer has been polluted it turns really difficult -and expensive- to clean it or revert the situation. Because groundwater, together with pollutants, moves slowly through the aquifer, contamination may remain undetected for many years. Once pollution is detected, it might be impossible to predict its expansion and extension underground. Besides, aquifers are connected, so a polluted aquifer may easily contaminate another one.
Different techniques can be applied to clean an aquifer; however, these are so expensive that almost nothing can be done to clean it up.
The contamination source, if detected, can be cut off, but the polluted area is hardly recovered.

How did Britain's policy of salutary neglect contribute to the Revolutionary War?
ОА.
Because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.
O B. Because the colonies did not have de facto independence, they revolted when Britain withdrew military and other aid.
OC. Because the colonies had de facto independence, they revolted when Britain granted other colonies true independence.
OD. Because the colonies felt de facto neglected by Britain, they revolted when it stopped contributing to their economy.
Answer:
A. Because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.
Explanation:
The American Revolutionary War was a war of independence of the United States of America that was fought between the 19th of April, 1775 and 3rd of September, 1783. The war started when the delegates from the thirteen (13) American colonies in Congress (First continental congress) revolted against the Great Britain over their lack of representation in the colonies and refusal to give consent to parliament's taxation such as Stamp Act and Townshend Acts.
Hence, Britain's policy of salutary neglect contributed to the Revolutionary War because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.
