Earth's global rainfall distribution

SCIENCE 9

1. Earth’s global rainfall distribution Presented by: Ma. Beatrice Herrera angela taylan gr. 9 - temperanza

2. precipitation it is the primary mechanism for transporting water from the atmosphere back to the earth’s surface this includes rain, snow, sleet, and hail

3. RAINFALL the quantity of rain falling within a given area in a given time

4. TROPICAL REGIONS ALSO CALLED AS “TROPICS”, ARE THE REGION OF THE EARTH NEAR THE EQUATOR AND BETWEEN THE Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere.

5. Temperatures are maximum at 32ºc and minimum at 18ºc because of the hot, humid weather and convergence of surface winds, heavy rain occurs

6. Temperate zones It is located between the tropic of Cancer and the Arctic Circle in the Northern Hemisphere or between the tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere

7. Temperatures can greatly change here because of its four seasons (Summer, winter, fall, and spring). Average temperature is between 0ºc - 20ºc. Air usually sinks to the surface. Therefore amount of rainfall is light.

8. Polar regions Are located at each end of the earth’s axis. The northern resting on the artic region and the southern on antartica .

9. Both poles are covered with ice and snow. Average temperature is less than 10ºc and the coldest temperature recorded is -89ºc in Antarctica These regions are partly dry because their cold descending air cannot hold much water vapor, precluding the formation of clouds and snowfall. Some regions receive 10 inches of precipitation each year.
