What have you learned about the earth’s atmosphere? It plays an important role in our lives. The earth’s atmosphere is composed of different layers where significant processes occur such as the weather systems. The different weather phenomena that we experience on the planet are the result of the interaction of factors and processes such as geography, location, and the sun’s radiation. This lesson will discuss the processes and behavior of the various weather systems.

Demonstrate an understanding on the account for the occurrence of land and sea breezes, monsoons, and inter-tropical convergence zone.
This module is divided into two lessons:
- Lesson 1: Behavior of heated air and surrounding air
- Lesson 2: Atmospheric Phenomena: Breezes, Monsoon, and Inter-tropical Convergence Zone (ITCZ)

1. explain what happens when air is heated;
2. describe the direction of heated or warm air;
3. cite the effect of unequal temperature of air in the atmosphere;
