What happens during a flood?

Prereading

Sediments are found almost everywhere.

Despite being strong, hard rocks, igneous rocks found on the surface of the earth can still suffer from erosion. This is when the wind and the water cause the rocks to break into smaller pieces. These pieces are called sediments. You could find sediments if you scoop up a glass of water at the beach. Every piece of sand at the bottom of the glass is a sediment.

Title 1

This river carries many sediments along its path.

The sediments from the igneous rocks are carried by water through rivers and lakes until the current stops and the sediment falls to the bottom. Although sediments are tiny, over time, more and more sediments fall in the same place. The pressure begins to compact the sediments into a solid rock.

Title 1

You can see the different layers of rocks that formed as sediments were compacted.

Sedimentary rocks are found in many beautiful landmarks and you can often see the individual layers of each type of sediment that was compacted. Sedimentary rocks are often used in construction. Sand and gravel are mixed together to form concrete. We also use sedimentary rocks to make beautiful beaches

Title 1

Sedimentary rocks are usually found on the surface of the earth and are constantly receiving more layers of sediment on top of them. Therefore the surface of the earth is always changing. Because of the pressure from all of the new sediments, the rocks are pushed down toward the centre of the earth. This causes them to change into another type of rock.

Causes

Sediments are deposited on top of each other.

Pressure presses the sediments together and forms a rock.

Rivers carry the sediments to a new place.

Wind and water erode the rocks and form sediments.
