p. p. of Rive.
An opening made by riving or splitting; a cleft; a fissure.
To cleave; to rive; to split; as, to rift an oak or a rock; to rift the clouds.
To burst open; to split.
A valley formed at a divergence zone or other area of extension.
An area of the earth's crust along which divergence is taking place, allowing a fault plane to intersect with the surface.
a break in the earth's crust due to separation of the two sides by tensional forces. Often a graben forms along the rift.
Crack in a rock. On a large scale it refers to the separation of plates on fault areas, forming a depression in the earth.
the zone between two diverging tectonic plates.
A long narrow trough, generally on a continent, bounded by normal faults, a graben with regional extent. Formed in places where the forces of plate tectonics are beginning to split a continent. (Example: East African Rift Valley).
The most pronounced direction of splitting or cleavage of a stone (see grain). Rift and grain may be obscure, as in some granites, but are important in both quarrying and processing stone.
A narrow cleft, fissure, or other opening in rock (as in limestone), made by cracking or splitting.
A long, narrow continental trough bounded by normal faults often associated with volcanic activity.
a personal or social separation (as between opposing factions); "they hoped to avoid a break in relations"
a (A) rock plate that moves vertically
a crack in the earth's crust which may result in a steep cliff as the land on one side rises or falls
a long, narrow continental trough that is bounded by normal faults
A cracking or splitting of the earth's crust.
It is a crack in a rock. In broader way it generally refers to the separation of plates on fault areas, forming a depression in the earth.
A distinct, roughly linear trough or depression on the earth’s crust that reflects a pulling apart of the crust due to tension.
break apart
Region where the crust has split apart, usually marked by a rift valley (e.g., East African Rift, Rhine Graben).
A break in the Earth's crust created by geological stress
An elongate trough in the earth's crust formed by tension and defined by normal faults.
The fracture system that forms where two tectonic plates pull apart (like the oceanic ridges) or where a single plate is being pulled apart (like the East African rift).
A rift (or graben) is a valley between two faults.
Direction in which stone splits most readily. Term commonly used for granite or other stone without visible stratification of foliation.
n. A long, narrow crack in the entire thickness of the Earth's crust, which is bounded by normal faults on either side and forms as the crust is pulled apart; v. To split the Earth's crust; rift zone- n. The area on continents where a trough bounded by normal faults is forming; the site of crustal extension, similar to that which occurs at mid-oceanic ridges; rift basin or rift valley- n. The long, and fairly wide trough that has formed as a section of the Earth's crust has dropped down along faults, e.g., African Rift Valley in East Africa.
continental scale collapse trench, normal faults bounded.
refers to the breaking apart of continental plates.
An opening or fissure. In geology, a large fault caused mainly by lateral movement.
In geology, a rift is a place where the Earth's crust and lithosphere are being pulled apart. Typical features are a central linear downdropped fault segment, called a graben, with parallel normal faulting and rift-flank uplifts on either side forming a rift valley. The axis of the rift area commonly contains volcanic rocks and active volcanism is a part of many but not all active rift systems.
