What is the water cycle?

A continuous process by which water moves between the Earth's surface, atmosphere, and living organisms, involving evaporation, condensation, precipitation, and collection.

Evaporation

The transformation of liquid water into water vapor, driven by heat from the Sun. It primarily occurs in oceans, lakes, and rivers, but also in plants through transpiration.

Condensation

The process where water vapor in the atmosphere cools and condenses, forming clouds. As more water vapor condenses, droplets become larger and heavier, leading to precipitation.

Precipitation

Any form of water that falls from the atmosphere to the Earth's surface. This includes rain, snow, sleet, and hail.

Collection

The process where water collects on the Earth's surface after precipitation. It includes rivers, lakes, oceans, and groundwater.

How does the water cycle transport matter?

The process by which matter, including water, is moved throughout the environment. The water cycle transports water in its liquid, solid (ice/snow), and gaseous (water vapor) states.

How does the water cycle transport energy?

The water cycle is driven by energy, primarily from the Sun. This energy causes water to evaporate and allows water vapor to rise in the atmosphere.

Convection

The rising of warm, less dense air in the atmosphere, carrying water vapor upwards. This is a key process in the water cycle, driving condensation and cloud formation.

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.
