Read the text, then answer the questions.
How a Camel Survives
A camel can cross a desert that would kill most animals. Almost every part of it helps. Its hump is not full of water. It is full of fat. The camel uses the fat for energy when there is no food, which is why the hump sags on a hungry camel. A camel has two rows of long eyelashes and can close its nostrils. Both keep sand out during a storm. Its feet are wide and flat. They spread the camel's weight so it does not sink into soft sand. A thirsty camel can drink a hundred litres in ten minutes.

Volcanoes
A volcano is an opening in the Earth's crust where hot rock reaches the surface. Deep underground, rock is so hot that it melts. Melted rock is called magma. Magma is lighter than the solid rock around it, so it rises. When magma reaches the surface it is called lava. Lava can pour out slowly in rivers, or it can burst out in an explosion, depending on how thick it is. As lava cools it hardens into new rock. Layer after layer, this new rock builds the mountain we call a volcano.
