In the Autumn term, Year 5 have been looking at mountains and rivers as part of our Connected Curriculum unit. One of the most important skills that we have had to learn is how the different type of mountain are formed. All the mountains look different from one another and this is down to how they are created.
- Volcanic mountains rely on volcanic activity to get bigger and example of this type of mountain are Mt St Helens in America.
- Fold mountains are created when tectonic plates collide and make the largest mountain ranges in the world like the Himalayas and Mt Everest
- Fault block mountains, like the Sierra Nevada in North America, are formed when the Earth’s crust cracks and forces some pieces up and others down
- Dome mountains are formed a little like Volcanic mountains except the magma pushes the ground up but never breaks through the surface. These mountains then have their sides eroded to make the dome shape. Examples can be found in the Rocky Mountains
- Plateau Mountains are created by the erosion of land by rivers and rainfall and are found in places such as New Zealand.
We learned about how these mountains are created and created explanations to go with the diagrams of the mountains.
In the next lesson we looked at how mountains are shown on maps using contour lines and how these show the height and the steepness of a mountain. These are advanced geography skills and we really enjoyed learning them and putting them into action.
