MOST IMPORTANT QUESTIONS OF GEOGRAPHY ICSE CLASS 10 , PART 04

1. AFFORESTATION PREVENTS SOIL FROM GETTING ERODED.

ü Afforestation is the planting of trees .the roots of trees can hold the soil and prevents from soil erosion.

2. LATERITE SOIL IS RED IN COLOUR

ü it is red in colour because of red soil which is formed by leaching

3. WHAT IS SOIL EROSION

ü Soil erosion may be defined as the detachment and transportation of soil by the agents of denudation such as weathering running water etc.

4. STEPS THAT COULD BE TAKEN TO SOIL EROSION.

ü agronomic measures

· strip cropping

· banned jhooming

· sheet erosion

· conserve grazing land

ü mechanical measures

· contour ploughing

· DPAP

· watershed

5. SIMILARITIES BETWEEN RED SOIL AND LAERITE SOIL

RED SOIL	LATERITE SOIL
High iron oxide	High iron oxide
Poor nitrogen and lime	Deficit of nitrogen and lime
Tamil nadu, Andra Pradesh	Tamil nadu, Andra Pradesh

6. BLACK SOIL DOES NOT GET LEACHED

ü Black soil does not get leached because of high holding capacity of moisture, it has high water retention capacity.

7. KHADER IS MORE FERTILE THAN BHANGER.

ü Khader is more fertile than bhanger because it is newly deposited alluvial soil at every year.

8. DEFINE:

ü SHEET EROSION: gradually removal of top layer of soil due to destruction of vegetation is called sheet erosion.

ü IN SITU: soil is formed at their originate position by weathering of parent rocks is called in situ

ü SOIL CONSERVATION: soil conservation refers to the steps taken to protect the soil from erosion.

9. ALLUVIAL VS RED SOIL

Alluvial soil	Red soil
Punjab, Haryana, west Bengal, Odisha	Tamil nadu, Karnataka, Andra Pradesh, Odisha

10. DIFFERENT REGION OF INDIA HAVING DIFFERENT KINDS OF SOIL

ü India has a vast latitude and longitude extent. Different type climate prevails in different parts of India; there are also different types of rocks which differ region to region so that different region of India has different types of soil.

11. CONSERVATION OF SOIL AS NATURAL RESOURCE

ü Conservation of soil is important because of wearing off the nutrients from the top soil may cause the less agriculture productivity.

12. SOIL IS GOOD FOR THE CULTIVATION OF CASHEW NUTS = laterite soil

13. SOIL COVERS ALL MOST IN WEST BENGAL= alluvial soil

14. SOIL IS A RESULTS OF LEACHING= laterite soil
