Activity 2.1

INTERACTION WITH NATURAL CYCLES

Aim:

Read the Fact Sheet about global warming.

When you have completed this activity you will have described some of the ways that people interact with a natural cycle.

Procedure:

  • Read about each part of the water cycle described below.
  • Label the drawing using the four terms in bold print.
    • Evaporation occurs when lakes, oceans, rivers and streams are heated by the sun. The liquid water evaporates into a gas called water vapour.

    • Condensation occurs when the water vapour comes together to make clouds.

    • Precipitation occurs when water from the clouds falls to earth as rain, hail or snow.

    • Collection occurs when the rain, hail and snow goes back into oceans, lakes, rivers and streams.

The Fact Sheet explains how global warming can affect the water cycle. In the table below, fill in the examples of human activities that contribute to global warming and damage the health of the water cycle.

Water pollution also damages the health of the water cycle. Write in some specific examples. Also describe how water pollution affects the health of the water cycle.

Human activities Examples How they can affect the water cycle
Air pollution Carbon dioxide from car exhaust Together they cause global warming. This will increase the amount of water vapour in the air.
