Types of Seashores

in Fresh/Geography/Nature/Science and Geography

There are different types of seashores

Rocky  Shores

These are sometimes bedrock and sometimes boulders. Have lots of spaces for animals and plants to live. They have to deal robustly with strong waves and the constant rose and fall of the tide. Different types of rocks influence what you will fond living on the rock itself. If sheltered those rocks might be covered with seaweed and provides protection and food for a variety of animals. If exposed – by for example the constant hotting of the waves – then this prevents the growth of seaweed

Rock Pools

These are created when the tide goes to and water is trapped in the rocks – live animals can be left behind

Sandy and Muddy Shores

Here animals might leave a hole, burrow, tracks, or a swirl of sand as something buries itself. Sandy beaches contain billions of particles brought in by the waves. Muddy shores usually form near river estuaries (eg. River Avon) where large mudflats can occur. Soil from the fields turns to mud, and comes down the river. When it reaches the sea these mud left overs may end up on the seabed near the sea. This silt is sculptured by the waves into the soft banks.

Shingle Beaches

Lots of pebbles – hard for animals to attach themselves to the rocks. Will only find lichens.
