Cycles of Matter
Matter Matter is recycled in an ecosystem, unlike energy. What is it? Anything that has mass and takes up space.
Water Cycle Condensation
The Water Cycle condensation
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.
Evaporation Liquid Gas add heat energy
Condensation Gas Liquid take away heat energy
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
What is a water molecule? Two hydrogen atoms and one oxygen atom. It is written as H 2 0.
Ice cube – solid phase
Water – liquid phase
Water vapor - gas phase
When heat energy is added to water molecules, they move faster and further apart.
Solid form of water
A drop of liquid water
Vapor form of water
Do the water molecules change what they look like when they change phase? No, they are still H 2 O! The water molecules only change in speed and the distance from each other.
Water Cycle Condensation
The Water Cycle Water is continually moving from the surface of Earth through the atmosphere in the three states of matter: solid liquid gas.
The Journey of Water Drop
Take a journey through the water cycle!

WATER CYCLE. Water Cycle WATER IS ALWAYS MOVING!!!
SOL 3.9 Tina Owen. What is the water cycle? The water cycle is the movement of water from the ground to the air and back to the ground by evaporation,
WHAT IS THE WATER CYCLE? Water is always moving between the atmosphere (troposphere) and surface of Earth. Water is always moving between the atmosphere.
