Archipelago

An archipelago, sometimes called an island group or island chain, is a chain, cluster, or collection of islands, or sometimes a sea containing a small number of scattered islands.

See McDonald Islands and Archipelago

Australia

Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands.

See McDonald Islands and Australia

Complex volcano

A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. McDonald Islands and complex volcano are complex volcanoes.

See McDonald Islands and Complex volcano

Dike (geology)

In geology, a dike or dyke is a sheet of rock that is formed in a fracture of a pre-existing rock body.

See McDonald Islands and Dike (geology)

Heard Island and McDonald Islands

The Territory of Heard Island and McDonald Islands (HIMI; ISO 3166 region code: HMD, HM, 334) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. McDonald Islands and Heard Island and McDonald Islands are complex volcanoes.

Indian Ocean

The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approx.

Kerguelen Plateau

The Kerguelen Plateau, also known as the Kerguelen–Heard Plateau, is an oceanic plateau and large igneous province (LIP) located on the Antarctic Plate, in the southern Indian Ocean.

See McDonald Islands and Kerguelen Plateau

Lava

Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface.

See McDonald Islands and Lava

Lava dome

In volcanology, a lava dome is a circular, mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano.

See McDonald Islands and Lava dome

Marine reserve

A marine reserve is a type of marine protected area (MPA).

See McDonald Islands and Marine reserve

Penguin

Penguins are a group of aquatic flightless birds from the family Spheniscidae of the order Sphenisciformes.

See McDonald Islands and Penguin

Phonolite

Phonolite is an uncommon shallow intrusive or extrusive rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic (fine-grained) to porphyritic (mixed fine- and coarse-grained).

See McDonald Islands and Phonolite

Pumice

Pumice, called pumicite in its powdered or dust form, is a volcanic rock that consists of extremely vesicular rough-textured volcanic glass, which may or may not contain crystals.

See McDonald Islands and Pumice

Pyroclastic flow

A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of but is capable of reaching speeds up to.

See McDonald Islands and Pyroclastic flow

Submarine volcano

Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt.

See McDonald Islands and Submarine volcano

Volcanic explosivity index

The volcanic explosivity index (VEI) is a relative measure of the explosiveness of volcanic eruptions.

See McDonald Islands and Volcanic explosivity index

World Heritage Site

World Heritage Sites are landmarks and areas with legal protection by an international convention administered by UNESCO for having cultural, historical, or scientific significance.
