Coral Reefs and estuaries

Front

What are Coral Reefs?

Back

Coral reefs are underwater structures made from calcium carbonate secreted by corals, which are marine invertebrates. They are typically found in shallow, warm, and clear waters.

Front

Why do Coral Reefs need lots of sunlight?

Back

Coral reefs require lots of sunlight for the symbiotic algae called zooxanthellae that live within the coral polyps. These algae perform photosynthesis, providing energy to the corals.

Front

What are the two main types of coral?

Back

The two main types of coral are hard corals (which build reefs) and soft corals (which do not build reefs).

Front

What are the main threats to Coral Reefs?

Back

The main threats to coral reefs include climate change, overfishing, and pollution.

Front

What is a Tide Pool?

Back

A tide pool is a shallow pool of seawater that forms on the rocky intertidal shore, usually at low tide.

Front

What is an Estuary?

Back

An estuary is a coastal area where freshwater from rivers meets and mixes with saltwater from the ocean.

Front

What role do zooxanthellae play in coral reefs?

Back

Zooxanthellae are symbiotic algae that live within coral polyps, providing them with energy through photosynthesis and contributing to the coral's color.

Front

How do Coral Reefs benefit marine life?

Back

Coral reefs provide habitat, food, and breeding grounds for a diverse range of marine species, supporting biodiversity.

Front

What is the significance of Coral Reefs to humans?

Back

Coral reefs provide benefits such as coastal protection, tourism, and resources for fishing and medicine.

Front

What is the intertidal zone?

Back

The intertidal zone is the area of the shoreline that is exposed to air at low tide and submerged at high tide.
