How Glass Is Recycled

Glass is unusual. It can be melted and remade for ever without getting any worse. Bottles are first sorted by colour. Clear, green and brown glass have to be kept apart, because you cannot make clear glass from green. The glass is then crushed into small pieces called cullet. Metal lids are pulled out with a magnet. Cullet melts at a lower temperature than the raw materials glass is made from. That means recycling glass uses less energy than making it new. The melted glass is poured into moulds and blown into new bottles.

  1. 1. What would a flow diagram for this text show?
  2. 2. What happens to the melted glass at the end?
  3. 3. What is crushed glass called?

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 would a diagram of a volcano need to label?
  2. 2. What builds the mountain?
  3. 3. What is it called once it reaches the surface?
