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. What is "magma"?
  2. 2. What does "crust" mean in this text?

Inside a Fire Engine

A fire engine carries everything a crew might need, because there is no time to go back for anything. It holds about eighteen hundred litres of water. That sounds like a lot, but a hose can empty it in under three minutes, so the crew connect to a hydrant as soon as they can. Ladders are carried on the roof. The longest can reach a third-floor window. Inside are cutting tools for road accidents, breathing sets for smoke, and a thermal camera that finds a hot spot through a wall. The engine is red so that it is seen. The siren is for when being seen is not enough.

  1. 1. What does "thermal" mean in "thermal camera"?
  2. 2. What is a "hydrant"?
