The process begins when rainwater seeps deep (29) __________ the Earth’s surface through a network of narrow channels. Down below, there is magma which heats the surrounding rocks. This intense heat causes the water temperature to (30) __________ dramatically.

Because of the weight of all the water above, the pressure at the bottom of the channels is very high. (31) __________, the water at the bottom can reach temperatures far above 100°C without boiling. Eventually, the superheated water expands and forces some water out at the top. This reduces the pressure, allowing the trapped water to violently flash into steam.

What exactly is a 'carbon footprint'? It is the total amount of greenhouse gases, particularly carbon dioxide, that are generated by our individual actions. Everything from the food we eat to the way we travel contributes to this total. For example, the electricity used to power our homes and the fuel burned by the motorbike we take to school both create emissions that affect our planet’s climate. Understanding this concept is the first step towards making a positive change.

When many people make these small changes together, the collective impact can be enormous and help protect our environment for future generations.
