Study Notes
The Water Cycle
- The water cycle describes how water moves continuously around Earth. This includes oceans, rivers, the atmosphere, and land.
- Water continually circulates through different states (liquid, gas, solid).
- Water flows from mountains to streams, then rivers, and eventually to the sea.
- Seawater evaporates, creating water vapor that rises into the atmosphere.
- As the water vapor rises, it cools, condenses, and forms clouds.
- Clouds release water as rain or snow, which falls back to land and water bodies.
- Water also evaporates from rivers, lakes, and plants through a process called transpiration.
- Fog and dew are other forms of water returning to the Earth.
- Water can also move underground.
- Volcanic activity releases steam that can contribute to clouds.
Water Cycle and Energy
- The water cycle transports both matter and energy.
- The Sun's energy drives evaporation, giving water molecules kinetic energy to rise.
- This kinetic energy transforms to gravitational potential energy as water vapor ascends.
- Convection currents, driven by differences in air temperature (hot air rises, cool air sinks), are crucial in moving water vapor upwards.
- When water falls as rain or snow, potential energy is released as kinetic energy with the falling water.
