What are the features of the Great Barrier Reef?
Some key facts about the Great Barrier Reef Marine Park: covers 344,400 km2 in area. includes the world’s largest coral reef ecosystem. includes some 3000 coral reefs, 600 continental islands, 300 coral cays and about 150 inshore mangrove islands.
What type of landscape or landform is the Great Barrier Reef?
Location. The Great Barrier Reef is a coral sea located on Australia’s north- eastern coast in the Coral Sea.
What are some landforms in the coral reef?
Coral reefs are generally divided into three classes: fringing reefs, barrier reefs, and atolls (pronounced A-toles). The simplest and most common type of coral reef, fringing reefs, form close to the shoreline of islands and continents.
Is the Great Barrier Reef dead?
In 2020, a study found that the Great Barrier Reef has lost more than half of its corals since 1995 due to warmer seas driven by climate change. As global warming continues, corals will not be able to keep up with increasing ocean temperatures.

How old is the Barrier reef?
500,000 years
Although coral reefs have been around for over 500 million years, the Great Barrier Reef is relatively young at 500,000 years, and this most modern form is only 8,000 years old, having developed after the last ice age.
What will happen if the Great Barrier Reef dies?
If coral reefs disappeared, essential food, shelter and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer as a consequence. Marine food-webs would be altered, and many economically important species would disappear.
What are the landforms features?
A landform is a feature on the Earth’s surface that is part of the terrain. Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills.
Is the sea a landform?
The oceans of the world are actually a landform of water that do take up 71% of the earth’s surface. It is made up of a total of 5 bodies of water. The world below the ocean contain a large variety of landforms as well. These include the following: mid-ocean ranges, guyots, abyss, trenches and even mountains!
What are the major land features of the marine biome?
Land Features Under the Ocean Marine regions include oceans, coral reefs and estuaries. The ocean meets the land in the “intertidal zone.” In the ocean, or rather under it, are continental shelves, abyssal plains (at the deepest points under the ocean), rises, ridges, basin-shaped estuaries and trenches.

Is coral alive?
Background. Corals consist of small, colonial, plankton-eating invertebrate animals called polyps, which are anemone-like. Although corals are mistaken for non-living things, they are live animals. Corals are considered living animals because they fit into the five criteria that define them (1.
What are plain landforms?
