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.

Earthquakes
The Earth's crust is not one piece. It is broken into huge slabs called plates, and the plates are always moving — about as fast as your fingernails grow. Where two plates meet, they can catch on each other. Pressure builds up for years while they are stuck. When they finally slip, all that stored energy is released at once. The ground shakes. That shaking is an earthquake. Most earthquakes are too small to feel. A few are strong enough to bring down buildings, which is why new buildings in some places are made to sway.
