Collision Zones and Mountains What happens when two continental plates collide? Because the rock making up continental plates is generally lighter and less dense than oceanic rock, it is too light to get pulled under the earth and turned into magma. Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of __________________ .

At divergent boundaries , tectonic plates are moving __________ from each other. One result of huge masses of crust moving apart is ______________ spreading. This occurs when two plates made of oceanic crust pull apart. A crack in the ocean floor appears and then magma oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a _______________ ___________. The magma also spreads outward, forming _________ ocean floor and _________ oceanic crust. When two _______________ plates diverge, a valley-like rift develops. This __________ is a dropped zone where the plates are pulling apart. As the crust widens and thins, valleys form in and around the area, as do _______________, which may become increasingly active. Early in the rift formation, streams and rivers flow into the low valleys and long, narrow lakes can be created. Eventually, the widening crust along the divergent boundary may become thin enough that a piece of the continent breaks off, forming a new tectonic plate. Name 2.
