The Great Rift Valley (Swahili: Bonde la ufa) is a series of contiguous geographic depressions, approximately 6000 or 7,000 kilometres (4,300 mi) in total length, the definition varying between sources, that runs from the southern Turkish Hatay Province in Asia, through the Red Sea, to Mozambique in Southeast Africa. [1][2] While the name ...
Midcontinent Rift System. The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American Plate. It formed when the continent's core, the North American craton, began to split apart during the Mesoproterozoic era of the ...
The Rio Grande rift is a north-trending continental rift zone. It separates the Colorado Plateau in the west from the interior of the North American craton on the east. [1] The rift extends from central Colorado in the north to the state of Chihuahua, Mexico, in the south. [2] The rift zone consists of four basins that have an average width of ...
Geographically, South America is generally considered a continent forming the southern portion of the landmass of the Americas, south and east of the Colombia–Panama border by most authorities, or south and east of the Panama Canal by some. South and North America are sometimes considered a single continent or supercontinent, while ...
The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge. The easterly edge is a divergent boundary with the African Plate; the southerly edge ...
The Peru–Chile Trench, also known as the Atacama Trench, is an oceanic trench in the eastern Pacific Ocean, about 160 kilometres (99 mi) off the coast of Peru and Chile. [1] It reaches a maximum depth of 8,065 m (26,460 ft) below sea level in Richards Deep (23°10′45″S 71°18′41″W) and is approximately 5,900 km (3,666 mi) long; its ...
The Atlantic Ocean is the second-largest of the world's five oceanic divisions, with an area of about 85,133,000 km 2 (32,870,000 sq mi). [ 2 ] It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South ...
The two continents seem to have started to split apart at what are now their southern tips, with the rift extending northward along the modern coastlines to the Benue Trough, then later split along what is now the southern coast of West Africa and the north eastern coast of South America. As the continents were wedged apart, the trough opened.
