Class 5 The World Around Us — Water — the essence of life

Name the forms water takes, follow it round the water cycle, tell groundwater from surface water, and recognise the plants and animals that live in freshwater.

Name: ________________________

Before you start

A stretch of land that water has shaped, and the name of each part of it.

123456
  1. 1. Ice cap
  2. 2. Glacier
  3. 3. Waterfall
  4. 4. River
  5. 5. Lake
  6. 6. Forest

Water is doing the same thing at each of these: coming down off the high ground and gathering in the low. The ice cap and the glacier are it held as solid; the waterfall, the river and the lake are it moving and pooling.

  1. 1.Water rises as vapour, gathers as cloud, falls again and runs back to the sea, over and over. What two-word name does this circular movement have?

  2. 2.A village digs wells, borewells, tube wells and handpumps. What are these for?

    • a) Carrying rainwater away from the fields
    • b) Holding water back to form a lake
    • c) Making salty water fit for drinking
    • d) Drawing up water stored under the ground

  3. 3.Where does a river usually begin its journey?

    • a) In a well dug into the ground
    • b) In the middle of a desert
    • c) Out at sea, where it turns towards the land
    • d) High up in the mountains

  4. 4.The water cycle goes round and round with no true beginning, so start it where the Sun's heat turns water into vapour and put the stages in order from there.

    • The vapour forms clouds
    • Water goes back to rivers, lakes and oceans
    • Rain, snow and hail come down
    • The Sun's heat turns water into vapour

  5. 5.Rain is falling on this piece of land. Tap the groundwater — the water that has sunk down and is stored deep below the surface.

    Write the number of the part.

    12345

  6. 6.Rain soaks into the soil and sinks down through soil and rock until it is stored deep below. What is that stored water called?

  7. 7.A fish and a pond heron live at the same pond. What does the fish have that moves it through the water?

    • a) A soft shell
    • b) Long legs
    • c) A tail tube for breathing
    • d) Fins

  8. 8.Why can the greater part of the water on Earth not be used for drinking?

    • a) Most of it is frozen into ice caps
    • b) Most of it is salty sea water
    • c) Most of it is held inside plants and animals
    • d) Most of it is stored too deep underground
