Water Cycle
Water Cycle
The continuous circulation of water on, above, and below the Earth's surface.
Evaporation
Evaporation
The transformation of liquid water into water vapor. In the water cycle, this occurs primarily from bodies of water like oceans and lakes.
Condensation
Condensation
The process where water vapor in the atmosphere cools and changes back into liquid form, creating clouds.

Study Notes
- The water cycle, also known as the hydrologic cycle, is the continuous circulation of water on Earth.
- The cycle involves physical transformations between solid, liquid, and gaseous states due to temperature changes.
- It's a continuous and limitless process with distinct stages.
- Water is essential for all life on Earth.
- The water cycle allows water to circulate through the hydrosphere, making it available for use.
Evaporation
- The process starts with water evaporating from the Earth's surface into the atmosphere.
- Liquid water from oceans and other bodies turns into gas due to sunlight and heat.
- Living things contribute through transpiration (plants) and perspiration (animals).
Condensation
- Water vapor moves through the atmosphere via wind.
- As vapor rises to higher altitudes, cooler temperatures cause it to condense back into liquid.
- This forms water droplets that accumulate in clouds, making them darker as they fill.
Precipitation
- When water droplets in clouds become too large and heavy, they fall as rain.
- In colder areas, precipitation may occur as snow, frost, or hail.
Infiltration
- Water reaching the ground penetrates the soil to become groundwater.
- The amount of infiltration is affected by soil permeability, slope, and plant cover.
- Infiltrated water can return to the atmosphere through evaporation or enter surface water bodies.
