What are the 3 main zones of a coral reef?

Coral reefs can be separated into three distinct zones: the back reef, reef crest, and fore-reef (Figure 7). The back reef includes the shallow lagoon between the shore and coral reef.

What are the main types of coral?

There are two main types of coral- Hard Coral and Soft Coral. Hard corals are made of a rigid calcium carbonate (limestone) and appear very much like rocks. Each polyp secretes a hard exoskeleton made up of calcium carbonate and a chalky internal skeleton that stays in place even after they die.

What are 5 characteristics that define coral reef zones?

Coral Reef Zones Video Scientists divide coral reefs into zones. They base these divisions on location within the reef and characteristics such as depth, wave action, light intensity, temperature, and water chemistry. Zones of the reef include: lagoon, back reef, reef flat, reef crest, and fore reef.

What are polyps coral reef?

Coral polyps are tiny, soft-bodied organisms related to sea anemones and jellyfish. At their base is a hard, protective limestone skeleton called a calicle, which forms the structure of coral reefs. Reefs begin when a polyp attaches itself to a rock on the sea floor, then divides, or buds, into thousands of clones.

What are 5 major abiotic factors in coral reefs?

Five major abiotic factors in coral reefs are water, temperature, sunlight, salt, and waves. All of these are parts of the coral reef ecosystem that are not alive but have a major impact on the conditions of that ecosystem. All coral reefs are found in ocean waters, mainly in shallow, tropical areas.

What is in a reef?

A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes—deposition of sand, wave erosion planing down rock outcrops, etc.

How many species are in coral reefs?

Coral reefs support more species per unit area than any other marine environment, including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Scientists estimate that there may be millions of undiscovered species of organisms living in and around reefs.

What are the types of coral reefs?

The three main types of coral reefs are fringing, barrier, and atoll. Schools of colorful pennantfish, pyramid, and milletseed butterflyfish live on an atoll reef in the Northwestern Hawaiian Islands. The most common type of reef is the fringing reef. This type of reef grows seaward directly from the shore.

Where are the 3 largest coral reef found in the world?

The Florida Reef (also known as the Great Florida Reef, Florida reefs, Florida Reef Tract and Florida Keys Reef Tract) is the only living coral barrier reef in the continental United States. It is the third largest coral barrier reef system in the world (after the Great Barrier Reef and Belize Barrier Reef).

Is coral a reef?

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. ... They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas.
