4. WHAT IS HEAT BUDGET (DEFINE) (kidsgeo.com) Incoming heat absorbed by the earth. Outgoing heat escaping the earth. In the form of radiation are balanced If not balanced it will be cooler or warmer (slideshare.net)

5. REASONS WHY EARTH BECOME WARM, COOL AND BALANCE  Warm More energy comes into the system than goes out of the system. (Global warming)  Cool Less energy comes into the system than goes out of the system.  Balance Incoming heat absorbed by the earth and outgoing heat escaping the earth.

6. EFFECT OF WARM, COOL, AND BALANCE A. Warm 1. People feel hot. 2. Forest will burn. 3. Typhoon will be stronger. (global warming) B. Cool 1. Body temperature drop 2.
