Climate change and the water cycle

Increased greenhouse gases in the atmosphere results in...

• Less heat energy trapped in the atmosphere

• More heat energy trapped in the atmosphere

• Less heat energy from the sun reaching the earth

Which of these are greenhouse gases? Tick all of the correct answers

• Carbon dioxide

• Methane

• Water vapour

• Helium

What is transpiration?

• Another word for condensation

• Evaporation from plants and soils

• A kind of precipitation like heavy rain

• When water is trapped in a reservoir

If there is more heat energy trapped in the atmosphere, that will cause...

• Less evaporation and transpiration

• More evaporation and transpiration

What happens to plants and the soil if there is increased transpiration?

• They hold water well because there is a lot around

• There will be more frequent, light rain to make up for it

• They loose water more quickly and can dry out and even die

Warm air can hold more water vapour than cool air

• True

• False

There will be more intense rainstorms because there is more water vapour in the atmosphere

• True

• False

When heavy rain falls and soil and plants are dry and compacted, they will easily be able to absorb all the water

• True

• False

What is run off?

• When rain isn't absorbed and causes flooding and direct movement of water into rivers and the sea

• A kind of race

• When rain is very easily absorbed and soaks into the ground

What is a glacier?

• A thick river of slow-moving ice

• A type of iceberg in the ocean

• Another word for transpiration

• A kind of greenhouse gas
