Answer 1

Soil is formed by the breakdown of larger rocks into smaller rock particles. This can occur through the action of wind which causes breakdown of rocks, action of temperature and heat, effect of chemicals on water rocks and through the movement of plant roots which causes cracking in rocks. Also microorganisms decay the organic matter and add it into soil.

The four main processes involved in water cycle are evaporation, condensation, precipitation and collection.

Nitric oxide and nitrogen dioxide are formed by nitrogen and oxygen in the nitrogen cycle
