Soils vary throughout the world. Climate, elevation, plant growth; these are just some factors that influence weathering and soil formation. The tundra and the desert are alike in some ways; different in others. Both the tundra and the dessert have little available water for plant growth.

Imagine you are collecting soil samples from a desert location and the tundra. What might these soil samples have in common?

A) a very low amount of humus
B) lots of decomposing tree roots
C) very small, fine-textured soil particles
D) a large amount of sand and very little silt or clay

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the correct answer is b

what bodys are there orbiting?

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
