Interior Plains The Interior Plains is a vast physiographic region that spreads across the Laurentian craton of central North America.his area was originally formed when cratons collided and welded together 1.8–1.9 billion years ago in the Trans-Hudson orogeny during the Paleoproterozoic Era. Precambrian metamorphic and igneous rocks now form the basement of the Interior Plains and make up the stable nucleus of North America.

- The architects of coral reefs are hard corals. Unlike soft corals, hard corals have stony skeletons made out of limestone that is produced by coral polyps. When polyps die, their skeletons are left behind and used as foundations for new polyps.

- LOCATION: Coral reefs are generally found in clear, tropical oceans. Coral reefs form in waters from the surface to about 150 feet (45 meters) deep because they need sunlight to survive. The three types of reefs include fringing reefs, barrier reefs, and atolls.

Coral Reefs 12. Paradox is that coral reefs have such high productivity in nutrient poor areas. Reasons why: very efficient relationship between coral and zooxanthellae, high flow rate of water over reef, and rapid recycling of nutrients (high levels of bacteria).

INTERIOR PLAINS - GEOGRAPHY The Common Name for the Interior Plains region is the Prairies. The Interior Plains were covered by shallow seas. Sediments from the Canadian Shield and Western Cordillera were kept in the seas for over millions of years. Eventually the sediments were compressed by the layers into sedimentary rock. Some bodies of water that are in the Interior Plains region is the Saskatchewan River, Lake Winnipeg, Great Slave Lake and Great Bear Lake. In the North is Tundra which is a treeless area where the ground is always frozen.

Great Barrier Reef The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).The reef is located in the Coral Sea, off the coast of Queensland, Australia.The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms.resentic reefs are also found in the far north of the Great Barrier Reef Marine Park, and in the Swain Reefs (20 – 22 degrees south). Planar reefs are found in the northern and southern parts, near Cape York Peninsula, Princess Charlotte Bay, and Cairns.

Abyssal Plains They are found within the bounds of the ocean floor and in the transitional zone and are divided into two morphological types—flat, or subhorizontal, and hilly. Flat abyssal plains are confined to the margins of ocean basins or to the centers of the basins of epicontinental seas. Hilly abyssal plains occupy a large part of the bottom of the ocean floor. The surface of the flat abyssal plain is characterized by exceptional evenness, with floor gradients of less than 0.001. Starkly contrasting solitary seamounts, evidently of volcanic origin, are also found.

Interior Plains The Interior plains region of the United States and Canada falls within this area. The Interior Plains were often covered by shallow inland seas. Sediments from the shield and the Rocky Mountains were deposited in these seas over millions of years.

Ethiopia's Magnetic Stripes Hold Clues to Ocean Formation Tendaho's magnetic bands, which measure 6 miles (10 kilometers) wide, are embedded in continental crust, not oceanic crust. And unlike magnetic stripes on the ocean floor, Tendaho's formed through diking: as the African crust stretched thin, streams of magma intruded the continental crust and hardened.Like in the oceanic stripes, ferromagnetic minerals in the dikes aligned with the planet's magnetic field as the magma hardened.cientists predict it could be as many as 2 million years before the crust in the Tendaho Graben ruptures and begins to form an ocean basin. Altogether, this means that Tendaho's magnetic stripes could predate the future ocean basin by nearly 4 million years.

Coral Reefs and Sinking Islands: Revisiting Darwinâs Other Theory Tahiti’s coral, for example, forms a ‘fringing’ reef, a shelf growing close to the island’s shore. The ‘barrier’ reefs of Moorea are separated from the main island by a calm lagoon. Finally, an ‘atoll,’ such as Manuae, appears as a ring of coral enclosing a lagoon with no island at its center.

Coral Reef Biome Facts The Great Barrier Reef is the largest coral reef biome and is located in Australia. It can actually be seen from outer space. The diversity of the species living within different coral reefs depends on the reefs' latitude and the direction of the water.Coral reef biomes must exist in shallow water because they must remain between 70 to 85° F. Shallow water is easier to keep warm by the Sun than deeper water.he diversity of the species living within different coral reefs depends on the reefs' latitude and the direction of the water.

The top threats to coral reefs — global climate change, unsustainable fishing and land-based pollution — are all due to human activities. These threats, combined with others such as tropical storms, disease outbreaks, vessel damage, marine debris and invasive species, exacerbate each other.

Boreal Plains The Interior Plains consists of coral reef in the layers of sedimentary rock, the coral reef also supplies much of the oil found in Alberta and Saskatchewan. When the water in the Interior Plains evaporated mineral deposits were left in the dried out sea beds.

Precambrian metamorphic and igneous rocks now form the basement of the Interior Plains and make up the stable nucleus of North America. With the exception of the Black Hills of South Dakota, the entire region has low relief, reflecting more than 500 million years of relative tectonic stability.

Definitions &Translations An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3000 and 6000 m. Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth ’s surface.They are among the flattest, smoothest and least explored regions on Earth.byssal plains result from the blanketing of an originally uneven surface of oceanic crust by fine-grained sediments, mainly clay and silt. Much of this sediment is deposited by turbidity currents that have been channelled from the continental margins along submarine canyons down into deeper water.

Why are coral reefs so important? The surface of coral reefs in the Indo-Pacific may also be the place of habitat of human cultures that have lived there for centuries. These people can literally live on the immersed surface reefs, cultivate these soils, build their dwell from coral blocks, and even build artificial islands where families can settle.
