It is made up of thousands of smaller reefs and islands. You can even see parts of it from space! It is home to about 400 kinds of coral and thousands of fish species. However, global warming is a big threat. Higher sea temperatures cause coral bleaching, where the coral turns white and dies. Landforms are the natural shapes of the Earth’s surface. Common landforms include mountains, volcanoes, hills, plains, rivers, lakes, islands and waterfalls. Mountains are high landforms, often formed by the movement of the Earth’s crust. Volcanoes are special mountains that can erupt and create new land, like islands. Plains are large, flat areas, usually good for farming. Islands are pieces of land surrounded by water. Rivers are flowing water bodies that cut through land and form valleys over time. Documentaries about landforms often use bird’s-eye view shots. These shots show the true size and beauty of the landforms, helping people understand how amazing our planet is. ( ) 1. What is the Great Barrier Reef made up of? A.
