In many tropical areas, rain forests have been clear cut in an effort to grow food crops. this effort has not been successful because tropical rain forests a) have water-soaked or saturated soils. b) have sandy soils that do not hold water. c) have poor soils with little organic matter. d) have soils with a very high organic matter conten

The correct answer is option C, that is, have poor soils with little organic matter.  

In the tropical rain forests, only a thin covering of decaying organic matter is present. The majority of the tropical rainforest soils are comparatively poor in nutrients. The torrential rains and millions of years of weathering have washed the majority of nutrients out of the soil.  

In the tropical rain forests, the soils are generally poor in nutrients and all the nutrients are captivated in the living species. The soils in various regions of the tropical rain forests are laterite soils.  

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

the correct answer would be false.
