7.28.M - Lesson: The Water Cycle

Water Cycle

Continuous movement of water through various states.

Evapotranspiration

Combination of evaporation and plant transpiration.

Evaporation

Liquid water changes to gas due to heat.

Transpiration

Plants release water vapor through leaves.

Condensation

Water vapor cools and forms liquid droplets.

Precipitation

Water falls as rain, snow, sleet, or hail.

Surface Water

Water found on the ground's surface.

Groundwater

Water that flows beneath the Earth's surface.

Watershed

Land area draining into a specific water body.

Aquifer

Freshwater

Water with low salt concentration, essential for life.

Saltwater

Water with high salt concentration, primarily in oceans.

Photosynthesis

Process where plants convert sunlight into energy.

Ecosystem

Community of living organisms interacting with environment.

Water Supply

Total amount of water available on Earth.

Finite Water

Limited quantity of water available on Earth.

Water Vapor

Gas form of water present in the atmosphere.

Humidity

Amount of water vapor in the air.

Energy Pyramid

Hierarchy of energy transfer in ecosystems.

Marine Habitat

Ecosystem found in ocean environments.

Freshwater Habitat

Ecosystem found in lakes and rivers.

Arid Ecosystem

Dry environment with limited water availability.

Water Cycle Steps

Evapotranspiration, condensation, precipitation are key processes.

Leonardo Da Vinci

Renaissance scientist who studied water movement.

Pierre Perrault
