What are the methods that can be adapted to contain landslides?
Solution :
Construction of a retention wall to stop land from slipping and increase in the vegetation cover can be adapted to contain landslides.
Effective surface drainage system is a major way to control landslides during rainy season and spring flows.
Hazard mapping can locate areas prone to landslides. These areas can be avoided for
building settlements and hence avoid loss of life and property in the event of a Landslide.
Chapter 2 Geography Class 8 Extra Questions Question 6
Give a brief description of soil composition or the layers of soil ?
Solution :
Soil can be classified into 4 major layers. They are:-
Horizon O
Horizon A
Horizon B
Horizon C
Horizon O refers to the upper layer of soil, nearest the surface. It is commonly known as topsoil. This layer includes organic litter, such as fallen leaves and twigs. The litter helps prevent erosion, holds moisture, and decays to form a very rich soil known as humus.
Horizon A is the layer below Horizon O. Litter is not present in horizon A and therefore there is much less humus. It consists of subsoil with sand, silt and clay.
Horizon B is below Horizon A. Horizon B consists mostly of weatherized big rocks. This solid rock gives rise to the horizons above it.
Horizon C is found below Horizon B and consists of parent rock.

Write a brief note on terrace farming and intercropping.
Solution :

Intercropping is different crops grown in alternate rows and are sown at different times to protect the soil from rain wash.
Land Soil Water Natural Vegetation And Wildlife Resources Class 8 Extra Questions Question 10
What is a ‘water-cycle’?
Solution :
Rivers, lakes and oceans lose water everyday because of evaporation due to the heat of the sun. That water travels into the air as water vapour and becomes part of a cloud. Through condensation, the water vapour in clouds becomes a liquid such as rain, snow or sleet which is called precipitation. The water then comes back to the earth and the process begins all over again.
