THE WATER CYCLE
Transcript of THE WATER CYCLE
About the Water Cycle
The water cycle happens everyday! The water cycle is the path the water takes from the earth to the clouds, then back to start all over again. The water cycle have steps to it for the water cycle to be complete. Water cycles go forever. The water cycle is continuous.
Evaporation and Transpiration
Evaporation and transpiration are one of the first steps of the water cycle. Water cycle basically begins with evaporation and transpiration. Evaporation is where the water gets heated up and turns into water vapor and rises into the air. Transpiration is when the water from the plants rises as they heat up. They rise into the air through water vapor and heat to get the water cycle going.
After evaporation and transpiration comes, condensation comes. Condensation occurs when the water vapor in the air gets cold and turns back into liquid. Then, the the liquid in the air changes into a cloud. That is condensation.
After condensation, precipitation happens. Precipitation occurs when the clouds gets heavy and the cloud can't hold the weight anymore. So, it starts to rain, sleet, snow, or hail. That's precipitation. The precipitation fills up our lakes, streams, rivers, oceans, or any other water areas.
A surface runoff occurs when precipitation flows over the land. Sometimes the precipitation will flow down a slope or a hill. That's called a surface runoff.
When earth stores up water from precipitation and saves it in the earth, that is called groundwater. Groundwater is saved for later use. An aquifer is the storage area for underground water.
After evaporation, transpiration, condensation, precipitation, surface runoff, and groundwater... the water cycle starts all over again!

Acid rain is a form of air pollution. Acid rain happens when a chemical reaction like sulfur dioxide and nitrogen oxides are released into the air. They rise high into the atmosphere where they mix and react with water, oxygen, and other chemicals. Most causes of acid rain are the human activities, such as the gases from a factories.
Acid rain can affect the earth in many different ways. It can damage soil, trees, lakes, and buildings. Acid rain can hurt people, animals, and plants.
Acid rain can also damage soil by washing away the nutrients the soil needs to survive with.
Acid rain can hurt trees and plants. Acid rain washes away important nutrients, which can stop the plants and trees from growing. Some trees and plants may die from acid rain.
Acid rain can damage lakes and water. It can fall into lakes and other water areas and damage the area.
Acid rain can also damage rocks and buildings. Acid rain can damage rocks and buildings by eating away the minerals.
