c. rich in microorganisms
d. a fast developing soil
The correct answers are:
D. All of the above;
The versatility of the soil types and their properties in different regions is a result of multiple factors, including the climate of the place, the amount of rainfall, the topography of the area, as well as the organisms that live there. All of them have contribute in their own unique ways to the soil formation, and what kind of soil it will be.
B. Fragile;
The permafrost soil, also known as gelisol, is a soil type that is very fragile. This type of soil is very thin, it has almost no natural protection, the humus layer is is in the top couple of mm, and it is easily eroded.

Answer:
Disapear in a great Earthquake
Explanation:
The snow at the top of the Himalayas seems eternal and dormant, but it is not: it grows at an annual rate of four millimeters due to plate tectonic pressure, which increases the fear of an earthquake in Nepal. The phenomenon escapes the human eye, but dates back millions of years. The Indian plate slowly slips under the eurasian plate, and this pressure gradually lifts the highest mountains on earth.
The mountain range grows 4 millimeters upward each year, because the Indian plate continues to slide between 2 and 2.5 centimeters annually under the eurasia. On the surface, the arm wrestling between the two plates has potentially terrifying consequences in Nepal, where experts predict a “big earthquake” and the population reacts in terror to any news of earthquakes elsewhere.
