A -it is a large volume of air whose temperature and humidity are fairly uniformand covers an extensive surface areab -it experiences high temperature-it is a zone of low pressure and the doldrums-the zone migrates to the north and south of the equator with apparent movement ofthe overhead sun-it is a zone where the S.E and N.E trade winds converge-it is associated with convectional rain and thunderstorms10.a - Temperature decreases with increase in altitude. -. Rainfall increases with height upto 300m then it starts to decrease- Windward slopes are wetter than leeward slopes. -. Atmospheric pressure decreases with increasing altitude. -. Local winds are common, they blow up slope during the day and down slopeduring night. -. In temp. Regime slopes facing the equator are warmer than those facing the polesb i - Increases air pollution from industrial activities. -. Deforestation uncontrolled logging.
- In temp. Regime slopes facing the equator are warmer than those facing the polesb i - Increases air pollution from industrial activities. -. Deforestation uncontrolled logging. Ii - Widespread changes in the natural ecosystem with grasslands and deserts areasexpanding as forested areas shrinks. -. Possible rise in temp. May increase evaporation rates leading increased rainfallin some areas. -. Increased rainfall will cause flooding of low lying areas. -. Water stored in polar glacier will melt leading to rise in sea levels and flooding ofcoastal lands. -. In temperate regions, winters are likely to be wetter and summer drier. -. Wetter warmer conditions may increase pests diseases thereby affecting humans,crops livestock. -. Change in climate is likely to cause extinction of various plants and animal species. -. Possible drought might increase in most parts of the world. -. Cause in change in agricultural activities massive crop failure leading to foodshortage. C i - A rain gauge consists of a funnel, metallic cylindrical container and a collecting jar. When it rains, water from direct rain drops collects into the jar through the funnelThe water collected is then poured into a graduated in mm measuring cylinder. The readings taken recorded. C ii - Thermometers six thermometers. -. Hygrometer. 11.

A Tropical convergence zone is a low pressure belt that lies between the tropicswhere the North East and South East trade winds convergeb - The forest is evergreen due to high rainfall and abundant sunshine- The trees grow tall to complete for sunlight- Trees have broad leaves to encourage water loss through evapo-transpiration transpire excess water due to high rainfall- these are mainly hardwoods due to abundant sunshine- Trees have buttressed roots to support their great heights and large trunks in thewet soils. -. Tree roots go deep into the ground for anchorage- There are many tree species due to the tropical conditions. -. The forest has little underground because the canopies block sunlight from reaching theground- The forests have numerous lianas climbers which twine around the tall trees to reachsunlight in the dense forest. -. Trees grow rapidly due to the high temperatures and high rainfall14.
