Tide Pools By: Brianna Pearson

Description Tide pools are areas on rocks by the ocean that are filled with seawater. Tide pools can be small, shallow puddles found high up on the shore or huge, deep holes nearer to the sea.

Tide pools form when the ocean covers the beach twice a day. Some of the plants and animals that live close to the sea are covered when the tide washes over them.

They have to be able to survive in both wet and dry conditions. The tides bring fresh oxygen and food to them. They have to be able to survive in both wet and dry conditions. The tides bring fresh oxygen and food to them. Between tides, some of the smaller pools become too warm and begin to dry up.

Many of the animals hide under cool, damp rocks and moist seaweeds so that their bodies do not dry out before the tide comes in again.

Formation The tides on Earth are strongly influenced, in addition to astronomical factors, by the sizes, boundaries, and depths of ocean basins and inlets, and by Earth's rotation, winds, and barometric pressure fluctuations.

Although it is the gravitation of the Moon and Sun that raises the tides, the energy in the churning waters is extracted from the rotational energy of Earth spinning on its axis.

Rock Crab The rock crab crawls across the ocean floor, using its claws to pick up pieces of food. The rock crab crawls across the ocean floor, using its claws to pick up pieces of food. It can also use its pincers to defend itself if it's attacked. It can also use its pincers to defend itself if it's attacked. Most crabs are scavengers and will eat almost anything -- even other crabs. Most crabs are scavengers and will eat almost anything -- even other crabs.

High Tide When high tide occurs the waves are at their farthest in shore. This is when the tide pools are replenished with more animals

Low Tide When low tide occurs the water level goes back out to sea. When low tide occurs the water level goes back out to sea. During this time, many animals become trapped in what are called tide pools. During this time, many animals become trapped in what are called tide pools.
