landfill A landfill is a place where trucks bring waste from cities or towns. The landfill is a low area of land that gets filled up with this waste. The waste is eventually covered with dirt and becomes "new land" in a way. The waste itself, mixed with other things, is sometimes used to build up new land in a body of water, like a harbor, for example. New buildings or even airports can be constructed on top of waste from a landfill. This building material itself is also called "landfill."
volcano A volcano is a mountain made from hot, melted rock that has come up from deep inside the earth. A volcano begins with an opening in the earth's crust made by force from underground. Then, with an explosion, hot melted rock is thrown into the air through this opening, along with lots of smoke, ash, small rocks, and gases. Volcanoes build up over thousands of years with repeated explosions. Most of the time, nothing is happening inside a volcano. The mountain may have trees and plants growing all over it. It is like it is sleeping--maybe for thousands of years-- but sometimes a volcano becomes active. When a volcano becomes very active, it can explode and pour out the hot, liquid rock that eventually cools and adds to the size of the volcano.
