Water Cycle

The hydrolic cycle describes the circulation of the planet’s water. Temperature and weather conditions influence whether water is gas, liquid, or frozen.

Oceans, rivers, lakes, and the atmosphere influence the movement of water.

Can you think why, where, and when this occurs?

What happens?

Recycling Water

Earth has been recycling liquid water, as solid ice, or as a gas vapour for billions of years.

When you drink a glass of water, think who may have tasted it before you.

A polar bear, a brontosaurus, a Viking, farm animals, or an ancient city dweller?

Evaporation and Condensation

The changing state of water is due to evaporation from the oceans into an invisible vapour. Clouds hold this and condensation produces liquid rain or snow.

Think about this process and trace the weather patterns that cause it.

The Hydrolic Cycle

Run-off rainwater may return into rivers by flowing into the oceans. The water in hydrolic cycle is part of a never ending pattern.

Make a picture, diagram, or collect images of the water cycle.

Your Local Water Cycle

Using your location, map out, make a chart of your local water cycle.

What factors may influence the water supply?

Glaciers and Snowfields

Glaciers and snowfields trap and contain freshwater in it frozen state. Snow and ice trap most of Earth’s freshwater.

12% of the earth is ice today. Thousands a years ago, it was a third of the planet.

Check out and contrast the changing nature of the frozen planet over time.

Sea Level Rises 

Melting ice caps and glaciers cause sea levels to rise. What is the impact for communities around the world?

Summary Water Cycle

The movement of water is a dynamic process. It involves changes in different physical states.
