Mengapa Benua Afrika relatif lebih aman dari gempa vulkanik dibandingkan dengan Benua Asia dan Benua Amerika?​

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)

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.

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.

Explanation:

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.

Colder weather can decrease plant enzyme activity. This then disrupts plant nutrient intake because plants secrete enzymes to digest surrounding materials for soil. Consequently, this can stunt growth or more severely cause them to die

Answer: domination of a government or social group by females

Explanation:

Matriarchy refers to the social system whereby women the primary power positions are held by the women in the society. These positions can relate to social privileges, roles of political leadership etc.

Matriarchal is a domination of a government or social group by females. An example of the matriarchal society is the Mosuo of China where inheritance is passed down through the female line. In these society, the women also have their choice of partners.

The Human Development Index takes into account 3 main things about a country:

1. Life Expectancy

2. Education

3. Standard of Living

Long work hours don't necessarily have to do with any of these categories  and it can also be associated with human rights violations (slavery, sweatshops, etc.), so this will not increase a country's HDI, so A is incorrect.

A commitment to education will definitely increase a nation's HDI. Gaining knowledge is part of human development, and a great education system hugely facilitates that. B is correct.

It might seem like having the highest GDP will make a country have a better standard of living, but this isn't always the case. A country could produce tons of things but pay the workers very little, so this would not lead to a good standard living. Although a high GDP usually means that a country is doing better, it doesn't necessarily increase a nation's HDI, so C is incorrect.

D is correct because living longer means that the life expectancy is higher. This means that better healthcare, services, treatments, medicines, opportunities, etc. are available in the country, and being able to live longer is very important for human development.

Have a wonderful day and keep on learning! :D

Answer: C. a commitment to the education of its population

D. people who live longer than the world average

Explanation:

I took the quiz

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.

Hope this makes sense :))

Answer:

the amount of total precipitation

Diversified economy ==> A nation with several climate zones exports almonds, cranberries, corn, wheat, and peaches.

Specialization ==> A nation rich in precious gem/stones just exports diamonds to be made into necklaces, rings, and other jewelry.

Single-resource economy ==> A nation with many pineapple plantations exports fresh pineapples, canned pineapples, and pineapple products.

Explanation:

Each of these economies differ from each other greatly.

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.

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.
