 STARTER: How do you think mountains are formed? Write your ideas into your workbook. We will re-visit this at the end of the lesson. Read page 16-19 of the textbook LI: We are learning how mountains are formed How mountains are formed Fold Mountains: Block Mountains: Volcanic Mountains: Cause (Fault) Stress Result Examples  Fold Mountains ▪ Fold mountains are formed when two tectonic plates collide ▪ This causes the Earth's crust to buckle and fold ▪ In turn, this process squeezes the layers of rock, pushing them upwards to create mountain ranges.  Fold Mountains Hanging wall- above the fault; it “leans into” the other Footwall- below the fault Fold Mountains- The Victorian Alps Fold Mountains Block Mountains ▪ Block mountains are formed when large areas of the Earth's crust are broken into blocks by faults, or cracks. ▪ Some blocks are pushed up, while others are pushed down ▪ This creates a mountain range with steep sides. Block Mountains Block Mountains- The Grampians Block Mountains Volcanic Mountains ▪ Volcanic mountains are formed by the eruption of molten rock (magma) from beneath the Earth's crust. ▪ When the magma reaches the surface, it cools and hardens into rock, building up over time to form a mountain. Volcanic Mountains Volcanic Mountains- Mount Macedon Volcanic Mountains  How was Hawaii formed? How was Hawaii formed? Watch the video carefully! Your task is to write a summary to explain how the Hawaiian Islands were formed. You should have approximately 10 key points.  Questions Complete questions 1, 3, 4 on page 19 (Make sure you answer your questions in FULL sentences!)  Plenary Go back to your ideas at the start of the lesson on how mountains are formed. Do you still agree with your idea? Why/ why not? If you had to give yourself a mark out of 10 for your ideas written in the start, what would you have given yourself? Why?
