water cycle quiz [notes over a picture] [1]

It begins to change back again from a vapour into a liquid. The clouds change from white and fluffy to grey and dense. As the breezes blow the clouds inland they rise and cool even more. The water falls as rain, hail or snow. It flows downhill in streams and rivers. Trees also give off water vapour which rises up into the sky. As it rises it begins to cool and form clouds of water vapour. It collects in hollows like lakes and reservoirs. The warm water changes into a gas and begins to rise. Some of the water soaks down through the rocks. The rivers eventually flow back into the sea. The Sun heats up the surface of the sea.

Which statement is INCORRECT? The water cycle is driven by the Sun. The Sun warms the surface of the sea. Warm air rises. As the warm air rises it gets warmer. The water becomes water vapour. Water vapour also rises up from trees. We see this as fluffy white clouds. As the clouds rise higher they cool. They change to dense grey clouds. The vapour is changing back to water. This falls as rain, hail or snow. The water forms into streams. It flows downhill. Sometimes it is stored in lakes. Sometimes in reservoirs. Some water soaks into the ground. It always ends up back in the sea. Then water cycle starts all over again.

To start the water cycle we need the Sun. You can find it in the top right hand corner of the picture. Click on it to make it appear. Over the picture is an invisible grid. Hover over the grid to find lots of notes. Click on each to make them appear. To check just how much you have understood from the notes there is a one question quiz down the right hand side. Simply find the statement which is INCORRECT. To start the activity again just refresh the page.
