When a continental plate is split by movements elsewhere on the plate, it will crack in an area of weakness (along fault lines, namely) and subsequently will form a rift valley. A rift valley consists of two sides (part of the solid plate) and displaced land in the middle, which moves downwards as the two adjacent plates move apart. A rift valley often forms the basin of a river, though not always. A good example of one is the Great Rift Valley in East Africa.
Geologic features are any physical features on the surface of a planet or moon, or of the rocks exposed at the surface, by any geologic process.
70% of earth feature is water
plateau
a large surface area
Geologic Maps show the arrangement and types of rocks at the Earth's surface.
uniformitarianism
The geologic principle that the same geologic processes that operate today operated in the past to change Earth's surface.
Surface Geologic Processes also reffered to as, Exogeneous Geologic Processes, are the processes that operates on the Earth's surface and helps to reconstruct the Earth externally. They include, Erosion, Weathering, Mass Wasting, Orogeny. Their agents are called the Epigeal Geological Agents, and include, Wind, Water, Glacier, Waves etc.
which surface feature was made by a destructive process
Antarctica, a continent that covers 10% of the earth's surface, is covered -- 98% of it -- by an ice sheet that contains 70% of the earth's fresh water.
A landform is naturally formed feature on earth's surface.
It is called an unconformity.
