ENVIRONMENT RESOURCES #3

IMPORTANT OF ATMOSPHERE RESOURCES

[1] Gases

[A] Oxygen

• oxygen is used by plant and animals for respiration.
• It also supports burning of materials
• animal supports animal life
• oxygen combine with water vapour for chemical weathering

[B] Carbon dioxide

• It is required bt plant for photosynthesis
• Carbon dioxide combines with water to produce chemical weathering.
• Green plant takes in carbon dioxide
• Carbon dioxide absorbs heat to control atmosphere temperature in the carbon cycle.

[C] NITROGEN

• Nitrogen is required by the plant for the manufacture of protein
• It combines with water to provide food for the plant growth
• Nitrogen in soil can be converted to nitrate in the soil.

[D] OZONE:- The ozone layer acts as a blanker to the earth. It protects the earth and its living things against the building effect of ultraviolet rays of the sun.

[E] WATER VAPOUR

• It is important for rain formation
• The resultant rain is used by plant and animals in the process of chemical weathering
• Water vapour moderate atmosphere temperature.
