You will learn about the words above throughout the lesson, but if you are still unsure of any of them then click on the links below for the definitions. As you use the words in your written work, highlight them and write a definition of their meaning.


Activity One - Review

In Year 7 you will have looked at the importance of water and how it helped to shape the landscape. The hydrological cycle (water cycle) is a closed system which means it has no beginning or end. Watch the youtube clip below and answer the following four questions:

            1. What is the water cycle?
            2. How does the water cycle work?
            3. Copy the diagram below and add the key terminology labels from above.
            4. Define all the words that are mentioned in the clip that you do not know the meaning of.

Activity Two - Weathering and Erosion

Weathering and erosion are vital processes of change. You may remember looking at processes when you explored the 'Wonderful World' unit in Year 7. You have had had a few sleeps since then though or you may be new to the school so it is always good to recap. Watch the YouTube clip and then answer the questions below.

  1. What is weathering?
  2. What is erosion?
  3. What are the different types of weathering?
  4. Design a flow chart to explain how the different sections of weathering occur.
  5. Copy the table below and fill in the columns explaining how water, ice and wind are all forms of erosion.
