Physical weathering, also known as mechanical weathering, is the class of processes that causes the disintegration of rocks without chemical change. The primary process in physical weathering is abras ...
The term tectonics refers to the study of the Earth's surface structure and the ways in which it changes over time. Tectonic processes typically occur at plate boundaries which are one of three types: ...
The surface of Earth is modified by a combination of surface processes that sculpt landscapes, and geologic processes that cause tectonic uplift and subsidence. Surface processes comprise the action o ...
The ocean can be conceptualized as being divided into various zones, depending on depth, and presence or absence of sunlight. Nearly all life forms in the ocean depend on the photosynthetic activities ...
Submarine canyons are more common on the steep slopes found on active margins compared to those on the gentler slopes found on passive margins. They show erosion through all substrates, from unlithifi ...
Topographical map grids are worked out in metres, with the grid lines being 1,000 metres apart.1:100,000 maps are divided into squares representing 1 km2, each square on the map being one square centi ...
The width of the continental shelf varies considerably – it is not uncommon for an area to have virtually no shelf at all, particularly where the forward edge of an advancing oceanic plate dives bene ...
Latitude and longitude The northernmost point of Earth is the geographic North Pole, in the Arctic OceanThe northernmost point on land is Kaffeklubben Island, north of Greenland (83°40′N 29°50′W), ...
Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure, and soil type.Gross physical features or landforms include intuiti ...
The Cocos Plate was created by sea floor spreading along the East Pacific Rise and the Cocos Ridge, specifically in a complicated area geologists call the Cocos-Nazca spreading system. From the rise t ...
Bounded by subducting, spreading and transform ridges, the Scotia plate lies in a particular setting. Surrounded by 2 major and 3 minor plates, its tectonic location is generally reflective of the rel ...
East Pacific and Chile Rise Main articles: East Pacific Rise and Chile RiseA triple junction, the Chile Triple Junction, occurs on the seafloor of the Pacific Ocean off Taitao and Tres Montes Peninsul ...
The northern boundary with the North American plate is a transform or strike-slip boundary which runs from the border area of Belize, Guatemala (Motagua Fault), and Honduras in Central America, eastwa ...
The Arabian Plate is one of three tectonic plates (the African, Arabian and Indian crustal plates) which have been moving northward over millions of years and colliding with the Eurasian Plate. This i ...
