landforms

Landforms are mountains, volcanoes, streams, lakes, oceans, valleys, hills and much more. The main things that I will be telling you about are how mountains are formed, how volcanoes erupt, the theory of tectonic plates and what makes up the amazing earth.

There are four tectonic plates around the world. They fit together like huge puzzle pieces. The forces beneath earth’s surface cause the plates to shift and move. When plates rub together volcanoes or earthquakes appear on the boundaries. Mountains are formed from plates pushing together, rubbing and colliding

Mountains are formed when pressured on the earths crust forces it to rise. It also pushes large blocks of rocks upwards. The earth’s core is similar to an apple core. The deeper you into the centre of the earths core it gets hotter and hotter. The earth is made up of an ‘outer crust; the mantle, an outer and inner core.

Landforms are constantly changing. These changes are caused by volcanoes, weathering, humans and glaciers. This is called continental drift. Pangaea is an ancient super continent that has drifted apart over millions of years.

When learning about landforms I found out that Australia has no tectonic plates. I also found out about the earths core and how volcanoes and mountains are formed and erupt.
