Ridge-push - Wikipedia, the free encyclopedia
Ridge-push is a proposed mechanism for plate motion in plate tectonics. Because mid-ocean ridges lie at a higher elevation than the rest of the ocean floor, gravity causes the ridge to push on the li...

; Gravitational force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone. It works together with Slab Pull, but is much less significant. See also Slab Pull.

As a crustal plate moves further from an oceanic ridge, it cools and becomes increasingly dense. This causes it to sink beneath the continental crust in a subduction zone. The weight of this sinking, cooling plate causes a major pulling action, which causes the rest of the plate to be pulled downwards as well.

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, typically having a valley known as a rift running along its spine, formed by plate tectonics. This type of oceanic ridge is ...

I expected Crist and Ridge to each add about five points to the ticket in their respective states, while I thought Portman would be a push. Something is seriously wrong with the Republican Party when even its relatively harmless and/or popular public officials can’t seem to get any respect from the voting public.

A modern ice-push ridge on the northwest shore of Gardner Lake in southeastern Connecticut is 0.6-1.2 m high and 1.2-3.1 m wide. In February and March 1967, the positions of survey stakes placed on the lake ice were measured periodically. ... Accession Number : AD0694373 ... Descriptive Note : Research rept.,

Denis Urubko and Serguey Samoilov have reached BC Aug 25, next day brought some equipment to 5200. 27-28 they rested in BC. Then they're planning the acclimatization push via normal route (NW ridge) till 7800. Perhaps, they are ascending now, Denis hasn't written yet today.
