How a Polar Bear Stays Warm

A polar bear lives where the sea freezes. It has three ways of keeping its heat in. Under its skin is a layer of fat up to eleven centimetres thick. Fat is a poor conductor, so heat does not pass through it easily. Above that is dense underfur, packed tight so cold water cannot reach the skin. On top are long guard hairs. Each one is hollow and clear, not white. They look white because they scatter the light, the way snow does. A polar bear is so well insulated that it can overheat if it runs too far.

  1. 1. The author says fat keeps the bear warm. What reason is given?
2.Read the text, then answer the questions.

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.

  1. 1. The author says magma rises. What reason is given?
