FRESHWATER• We can only drink CLEAN freshwater. We call this DRINKING WATER.• Water from rivers and lakes is NON-DRINKING WATER.
DON’T WASTE WATER• We must save water.• Only the 3% of all the water on Earth is freshwater.
The drought• When it doesn´t rain for a long time it’s difficult for the plants and fish to survive.• They usually happen in summer.
What is the water cycle?• The water cycle is a continuous process of EVAPORATION, CONDENSATION, PRECIPITATION and COLLECTION
The water cycle• When it is hot Water from the sea evaporates.• The water vapour condenses into tiny drops and form clouds.• When the clouds are cold, it rains or snow.• The rain or snow falls into the sea.
Water on Earth is always changing state and place. The water cycle.
EVAPORATION• When the Sun heats water, water vapour rises.
CONDENSATION• When the water vapor cools, it turns into water drops and form clouds.
PRECIPITATION• The wind moves the clouds. When the clouds cool, water from the clouds falls as rain. If it is very cold, the water freezes and falls as snow. Rain and snow are both types of precipitation.
COLLECTION• The water that falls to the ground eventually goes into rivers. It can travel to the rivers across the surface of the Earth or underground. Rivers take the water back to the ocean and seas.
