Situation 1: The climate of the place is warm and humid, and it rains frequently. The rocks in this region are rich in iron. Many organisms live in and around the rocks. Situation II: The climate is very hot, and the region receives scanty rainfall. The rocks in this region are rich in calcium. Very few organisms seem to live around the rock. Situation III: The climate is very cold and dry. The rocks in the region are rich in aluminium. Large organisms can be found on the rock, but tiny worms and insects are very few in number.
1. In which of the three situations is the formation of soil the fastest? Why?
2. In which situation is the formation of soil the slowest? Why?
3. In which of the situations would the soil formed be dry in texture?
4. In which of the situations would the formed soil be rich in calcium?
Answers
Explanation:
1: in situation 1 as it is warm and humid
2:in the situation 2 as example you can take desert where there is no soil but sand
3: in situation 2
4: in situation 2
Answer:
Here are the answers to each question.
1. Formation of soil is fastest in the first situation.
2. The formation of soil is slowest in the third situation.
3. The soil formed would be dry in texture in the second situation.
4. The soil formed would be rich in calcium in the second situation
Explanation:
1. Formation of soil is fastest in the first situation because
rainfall is one of the most important factors in soil formation therefore for a fast formation of soil, the necessary conditions are frequent rainfall and warm, moist conditions.
2. The formation of soil is slowest in the third situation because in very dry and cold regions , there insufficient rainfall for the formation of soil at a faster rate.
3. The soil formed would be dry in texture in the second situation because soils present in dry and hot regions will have low water content and therefore will be dry in texture.
4. The soil formed would be rich in calcium in the second situation because of the dry and hot conditions, the soil's water retention capacity would be low and therefore it will be lacking Nitrogen and Carbon but would be rich in Calcium.
