The Beaufort Sea is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, the Yukon, and Alaska, west of Canada's Arctic islands.

Globally, the distribution of uranium ore deposits is widespread on all continents, with the largest deposits found in Australia.

The island of Puerto Rico lies immediately to the south of the fault zone and the trench. The trench is 800 kilometres long and has a maximum depth of 8648 metres (28,373 ft) at Milwaukee Deep, which is the deepest point in the Atlantic Ocean.

The Durand Line refers to the porous international border between Afghanistan and Pakistan.

The Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right.

Venezuela is the largest foreign supplier of oil. The most vital oil region economically is an area in the coastal plains, the lowlands around Lake Maracaibo. 

One of the significant lake-forming force is movement of the tectonic plates that form the Earth's crust. When adjacent plates separate at fault lines, the steep, narrow gap between them can result in the formation of a graben. Some of the largest, deepest, and oldest lakes on Earth are graben lakes. Perhaps the most famous graben lakes are Lake Baikal, Lake Tanganyika and Rudolf.

The inner core of the Earth, its innermost hottest part as detected by seismological studies, is a primarily solid ball. It is believed to consist of an iron-nickel alloy, and may have a temperature similar to the Sun's surface.

Use of the word fjord is more general in the Scandinavian languages than in English. In Scandinavia, fjord is used for a narrow inlet of the sea.

A combustible compact black or dark-brown carbonaceous sedimentary rock formed from compaction of layers of partially decomposed vegetation and occurs in stratified sedimentary deposits.

In geology the term joint refers to a fracture in rock where the displacement associated with the opening of the fracture is greater than the displacement due to lateral movement in the plane of the fracture (up, down or sideways) of one side relative to the other.

The molten rock material that originates under the Earth's crustand forms igneous rock when it has cooled. When magma cools and solidifies beneath the Earth's surface, it forms what are known as intrusive rocks. When it reaches the Earth's surface, itflows out as lava and forms extrusive (or volcanic) rocks.
