TRANSCRIPT
Matter• Matter is recycled in an ecosystem,
unlike energy.
• What is it? Anything that has mass and takes up space.
Water Cycle
• It is a continuous process by which water moves from the Earth’s surface to the atmosphere and back.
• It includes the processes of– Evaporation– Condensation– Precipitation
Evaporation
Occurs when energy from the sun heats water causing the water molecules to become so active that some of them rise into the atmosphere as vapor.
Condensation• Condensation
is the process of water changing from water vapor to tiny droplets of water.
Precipitation liquid or solid
Rain, snow, sleet or hail
Water – liquid phase
Water vapor - gas phase
Do the water molecules change what they look like when they change phase?
No, they are still H2O!
The water molecules only change in speed and the distance from
each other.
