Q1: Multiple Choice Questions (MCQs)

(i) What is the topmost layer of soil called?
(a) Clay
(b) Topsoil
(c) Pebbles
(d) Silt
Ans: (b)
The topmost layer of soil is called topsoil, and it is essential for plant growth.

(ii) What is the dark, organic material in the topsoil that makes it fertile?
(a) Clay
(b) Sand
(c) Humus
(d) Silt
Ans: (c)
Humus is a dark, organic material formed from the remains of plants and animals. It makes the soil fertile.

(iii) Which natural process breaks down rocks into small pieces to form soil?
(a) Erosion
(b) Weathering
(c) Deforestation
(d) Overgrazing
Ans: (b)
Weathering is the natural process that breaks down rocks into small pieces, forming soil.

(iv) What is the process of planting trees and other plants on barren lands to develop new forest-like areas called?
(a) Overgrazing
(b) Erosion
(c) Afforestation
(d) Terrace farming
Ans: (c)
Afforestation is the process of planting trees on barren lands to develop new forest-like areas.

(v) Why does barren land erode at a faster rate?
(a) It lacks sunlight
(b) It lacks plant cover
(c) It has too much water
(d) It is too hot
Ans: (b)
Barren land erodes faster because it lacks plant cover, exposing it to the sun's heat and making it prone to erosion.

Q2: Fill in the Blanks

(i) Soil erosion mainly occurs due to wind and ____________.
Ans: flowing water
Soil erosion mainly occurs due to wind and flowing water. These elements wash away the topsoil.

(ii) Terrace farming is practiced in hilly regions to prevent ____________.
Ans: soil erosion
Terrace farming in hilly regions prevents soil erosion by reducing water force on slopes.

(iii) Bunds of stones are built along ____________ to prevent soil erosion near river banks.
Ans: river banks
Bunds of stones are built along river banks to prevent soil erosion caused by overflowing river water.

(iv) Cover crops are grown on barren land to protect it from the sun and ____________.
Ans: wind
Cover crops protect barren land from the sun and wind, preventing soil erosion.

(v) Shelter belts, rows of trees along farmland boundaries, reduce the force of strong ____________.
Ans: winds
Shelter belts reduce the force of strong winds, preventing soil erosion along farmland boundaries.

Q3: Match the Column (In a Table)

Ans:

Q4: True/False 

(i) Barren land erodes slower than land with plants.
Ans: False
Barren land erodes faster than land with plants because it lacks plant cover.

(ii) Cover crops are not used for anything other than protecting barren land.
Ans: False
Cover crops, besides preventing soil erosion, are often used as cattle feed.

(iii) Soil erosion mainly occurs due to wind and stagnant water.
Ans: False
Soil erosion mainly occurs due to wind and flowing water.

(iv) Terrace farming is mainly practiced in flat regions to conserve soil.
Ans: False
Terrace farming is practiced in hilly regions to prevent soil erosion on slopes.

(v) Afforestation contributes to soil erosion.
Ans: False
Afforestation helps prevent soil erosion by stabilizing the soil with tree roots.
