![]() Terrain The surface features of an area of land. Crustal deformation refers to the changing earth’s surface caused by tectonic forces that are accumulated in the crust and then cause earthquakes. The Earth where two plates move toward each other, and the oceanic plate plunges beneath the other tectonic plate. The constant plate tectonic motions between the Pacific and North American plates guarantees that the crust in the western US is continually building up stress. Plate Tectonics - Unit 2. ![]() ![]() Subduction zones A place on the surface of Seafloor spreading The movement of two oceanic plates away from each other, resulting in the creation of a mid-ocean ridge. Relative ages are usually determined by crosscutting relationships and the number of impact craters on planetary surfaces. Relatively rigid outer layer of the Earth (the lithosphere), made up of the crust and upper mantle, which contain the continents and ocean floors.Īs a geologic unit, in comparison to another. Mid-ocean ridge A continuous mountain range with a central valley, located on the ocean floor where two tectonic plates move away from each other allowing molten rock from the Earth's interior to move toward the surface.Ĭrustal plates, which result in changes in the position, size, and shape In Europa's case) that has a distinct origin and consists of dominants, unifying features that can be easily recognized A geologic unit that overprints a fault or fracture is younger than both the fault and the surrounding terrain that contains the fault.Ĭrust The outermost layer of a planet, composed of relatively low-density materials. Crosscutting relationships A geological principle that explains that a fault that cuts throughĪ rock must be younger than the rock itself.
