The Water Cycle Flashcards
Earth is a close system what does this mean?
This means that very little matter including water ever enters or leaves the atmosphere
What is the water cycle called and what does it do
It is called the hydrologic cycle and it cleans and replenish is water
What are the different forms of water give some examples
Solid, liquid, gas
Solid – ice and the glaciers
Liquid – lakes and oceans
Gas – steam
What are the different processes in the water cycle
Evaporation Condensation Precipitation Infiltration Run-off Transpiration
What is evaporation
The sun heats the water in oceans, lakes and rivers and turns it into gas called water vapour. What are vapour rises into the air.
What is condensation
As water vapour rises into the air, it cools down and changes into tiny drops of water. When these drops gather together, we see them as the clouds. The jobs are so small and light they can float into the air.
What is precipitation
When where at is forced to rise into the cooler part of the atmosphere, the tiny water drops in cloud join together and become heavier. They fall onto the ground or into oceans, rivers and lakes as rain, snow or hail
What is infiltration
When water lands on the ground as precipitation, some of it soaks into the soil.
What is run off
Some precipitation that falls to the ground also flows into rivers, lakes and oceans
What is transpiration
Plants and animals (Including humans) are also part of the water cycle. Plans take in water from the ground and it passes through their lives where it evaporates into the air
What are the two major stages in the water cycle
Stores and flows
Stores examples– Clouds, oceans, lakes, rivers, snowcaps, glaciers, reservoirs, watersheds, aquifers. Be
Examples of close – precipitation, stream flow, surface run-off, snowmelt, infiltration, groundwater discharge, evaporation, transportation.
