Holes

A bore is a kind of drilled well. Water is drawn up from underground through the bore hole by some kind of pump. The pump can be an electric pump, a hand pump, or a wind driven pump.

A cat flap is a small door, often cut through a larger door, that is just the right size for a cat to go through. The flap part of the cat flap is a small door, hinged at the top, so the cat can go through but wind and insects can't.

A channel is a waterway, or a path that has been worn by water. Channels can be so large you can't see the other side, or quite small, like a gutter by the side of a road.

The picture is of a channel that has been worn into the rock by the waves of the sea.

A chasm is an extremely deep hole or fissure in the ground. Chasms are usually very large, big enough for a person to fall into.

A cleavage is the hole left after you cleave something. More commonly though, a cleavage is the space between a woman's breasts.

A cleft is a hole between two parts of something, similar to a cleavage. The man in the picture has a cleft chin.

A crack is a long, thin break in something. Cracks are usually found in something big and hard, like a wall or a concrete building.

A crater is a large, circular hole in the ground that could have been caused by several different things. Craters can be many kilometers wide and very deep.

Craters are found on top of volcanoes, and they can be caused by meteors hitting the Earth. They are sometimes caused when the ground collapses above a large underground chamber like an old mine or a cave.

A dent is a hollow, like a shallow hole in a surface. Dents are usually caused by hitting something. The car in the picture has a dent in its side.

A dip can be one of many things. As a verb, you dip something by lowering it briefly into a liquid, for example the person in the picture is dipping some bread. The semi-liquid food he is dipping the bread into is also called a dip. Dips are very tasty, can be made from virtually anything, and are usually served with some kind of bread. Many dips are made with a yoghurt base.

A dip is also a shallow dent or depression in the ground, often seen where a drain crosses a road.
