THE IMPACT OF CHANGES BY HEATING OR COOLING

How these Changes affect Our Lives and the Earth

Page 2: How these Changes affect Our Lives and the Earth.

Water is changed by heat…

When heat is added to ice, it melts and forms water.

When heat is added to water,

it forms a gas: water vapor.

Page 3: How these Changes affect Our Lives and the Earth.

On Earth we see this as…

Glaciers melting

Snow melting

Fog

Adding heat changes the Earth in other ways…

The Sun warms soil and allows a see to germinate.

The Sun warms the sand at the beach.

The Sun provides heat for plants and animals.

Heat changes the rocks on Earth…

Some rocks change because of heat and pressure.

Some rocks are formed because the heat inside of the Earth is so great that it melts them. New rocks are formed when the molten rock cools.

Heat can cause change by melting...

Heat can cause change by cooking…

The Earth is changed by cooling...

Snow cools the ground and the

atmosphere.

Water enters small cracks in rocks. The water freezes and

expands. The cracks get bigger and will eventually break apart

the rock.

The water in the polar regions is

cooled and forms ice.

Heating and cooling…

Can cause change in the properties of materials.

Not all materials respond the same way to being heated.

Not all materials respond the same way to being cooled.
