Study Notes

Cyclonic Rainfall

Known as frontal rainfall, occurs when two air masses with different temperatures meet.
Warm air rises over cooler, denser air, forming a front where cooling occurs.
Cooling leads to condensation, resulting in the formation of clouds and subsequent rainfall.

Water Cycle

Oceans serve as the primary source of water on Earth.
Water evaporates from oceans, soil, plants, and other surfaces, entering the atmosphere as vapor.
Atmospheric water vapor condenses into clouds due to temperature changes.
Winds from the ocean transport moisture-laden clouds across land.
Precipitation occurs primarily as rain or snow over land, replenishing the soil and plant life.
Water that is not absorbed runs off into rivers and streams, a process known as surface runoff.
Surface runoff eventually flows back into oceans, completing the cycle.
The water cycle represents the continuous movement and transformation of water through Earth's various systems: oceans, land, and atmosphere.
