Natural Resources — Important Questions

Solar energy, Wind energy, Birds and animals, Forest resources

Renewable resources are those that can reproduce themselves or are inexhaustible. Solar energy, wind energy, birds and animals (bio-resources), and forest resources can regenerate naturally. Coal and natural gas are non-renewable as they cannot be reproduced once used.

Control grazing activity, Plant trees in fallow land, Construct check dams, Deep cultivation in fields

All the correct options are mentioned in the chapter as measures to prevent soil erosion. Controlling grazing prevents loosening of soil, planting trees holds soil particles, check dams control water flow, and deep cultivation reduces water speed. Increasing chemical fertilizers is not a soil erosion prevention measure.

Nature, man, and culture

According to the chapter, resources are made from the interactions of three elements: Nature (which provides the raw materials), Man (who utilizes them), and Culture (which determines how and why they are used).

Latin

The chapter states that the name 'Laterite' is derived from the Latin word 'Later' which means a brick. This soil gets its name because it becomes very hard when dry, like a brick.
