The correct answer is - C. from thawing the ground beneath them.
Tall buildings in Siberia have to be lifted from the ground because in most of Siberia the ground is not stable. The ground in this part of the world is under the influence of the permafrost for the biggest portion of the year, which makes the ground very rich with frozen water, but unlike the popular opinion that in Siberia the summers are cold too, they are actually not cold but pretty warm and temperatures can reach up to 30 C degrees. This warmth makes the ice and snow melt, thus making the ground very unstable and very rich with water, so any higher and heavier building will start sinking into it, and after that when the winter strikes again the lower part of the building will be trapped by the permafrost.
Answer:
<em>Natural causes of earthquakes </em>
Explanation:
Earthquakes are triggered<em> by the rapid energy release in some of the Earth's small rocks. Energy can be released by elastic stress, gravity, chemical reactions, or even massive body motion.</em>
The release of elastic strain is the most important cause of all these, because this form of energy is the only sort that can be stored in sufficient quantities on Earth to create major disruptions. This type of energy release related earthquakes is called tectonic earthquakes.
Answer: B.
The Moon's Mantle is too cold to move easily, and has no convection and no active tectonic plate motions, due to the Moon's smaller size and colder temperature than the Earth.
Answer:
1. A. True,
2. A. language
3. C. Contagious diffusion
4. A. True
5. A. relocation diffusion
6. C. popular culture
7. C. culture regions
8. C. Politicalism
9. D. All of the above
10. A. Emile Durkheim
11. A. Toponymy.
12. D. hierarchical diffusion
13. B. False
14. B. culture complex
15. B. False
Explanation:
- The contagiousness is rapid ad widespread diffusion that is characterized through the population. Relocation diffusion is the spread of ideas through the diffusion and the movement of people from one place to another. Popular culture is a set of the objects and practices of the belief that are dominant in a society.
- A culture region refers to the homogeneous human aspects of a region, Emile Durkheim explained totemism and has claimed to see the origin of totemism. Cultural complex is a combination of cultural traits. And hierarchical diffusion is spread of ideas form a higher-order to a lower order of culture.
