water cycle

Explain the difference between hygroscopic and capillary water

Cannot be easily absorbed

Can be easily absorbed

Explain the water cycle

Water moves from atmosphere to earth by precipitation (rain,snow,fog,hail,frost)

Part of water that reaches earth is absorbed by the upper layers of soil (hygroscopic or capillary)

Some water filters through upper layers of soil (gravitational water) Water is absorbed by soil (infiltration)

Some water runs off to form streams

Underground water reaches soil surface again via springs

Water reaches atmosphere by evaporation

Plants transpire and lose water to atmosphere (form of water vapour)

Water vapour condenses to form clouds

How do plants lose water to atmosphere

Transpiration

What is gravitational water

Water filtered through upper soil layers to water table
