Question

what is terrace farming?how does it help to conserve soil?

Answer 1

Terrace farming is a practice of preventing rain water to tun off the slopes.The roots hold the soil and prevents soil erosion.

Answer 2

Ans: The factors that determine soil formation are:

1) Composition of parent rock: The inorganic elements and minerals contained in the soil will be similar to those contained in the parent rock.

2) Time of soil formation: The longer the time a soil has taken to form, the more mature it will be because the parent rock materials have been exposed to wreathing and have supported vegetation for a longer time.

3) Topography: Soil in hill regions get washed away easily as it is formed and so the soil is immature here.

4) Climate: Temperature and moisture influence the rate of physical and chemical weathering and determine the rate of soil formation. Decomposition of organic matter in the soil also influenced by climate.

5) Living organisms: Aerating agents like earthworms and plant roots help in making the soil fertile and prevents erosion, respectively.
