| Question | Answer | ||
|---|---|---|---|
| crust | earth outer layer the coolest and least dense layer of earth see also core and | tectonic plates | massive, rigid slabs of Earth’s lithosphere (crust and upper mantle) that constantly move over the weaker asthenosphere, fitting together like a puzzle. |
| mantle | the layer of earth beneath the crust it is about 2,900 km {thick, and makes up about 83 percent of earth or interior see also core and crust | lithosphere | the cool solid outer shell of earth it consists of the crust and the rigid uppermost part of the mantle and is broken up into segments |
| outer core | 2,260 km thick, turbulent liquid layer of iron and nickel located between the mantle and solid inner core. | fracture | the breakage of a rock into two or more pieces |
| inner core | a solid, hot sphere of iron-nickel alloy at the planet’s center, roughly 1,221 km in radius (about 70% of the Moon's size | elasticity | the ability of rock to be stretched and then return to its original position once the stress has been removed |
| latitude | the distance north or south of the equator measured in degrees see also longitude | stress | the amount of force being applied to a rock or Surface |
| longitude | the distance east or west of the prime meridian in Greenwich england measured in degrees see also latitude | strain | physical deformation of materials (ratio of extension to original length), a painful muscle or tendon injury caused by overstretching or overuse, or a genetic variant within a biological species. |
| oceanic ridge | continuous, 65,000-km (40,000-mile) long underwater mountain range formed by plate tectonics, where divergent plates move apart, allowing magma to rise and create new seafloor | plate boundary | a place where piece of the broken lithosphere meet boundary types include convergent divergent and transform |
| sea-floor spreading | a process by which new sea-floor is formed from the magma rising from earth diverging oceanic plates | continental crust | crust that contains mostly land ranging from 15 to 70 kilometers 9 to 43 miles |
| divergent boundary | occurs where two tectonic plates move apart, causing magma to rise from the mantle, solidify, and create new crust. | oceanic crust | crust that lies beneath the ocean ranging from 5 to 10 k 3 to 6 mi thick |
| transform boundary | the process by which one plates of the lithosphere sink and slides under another | friction | a fore that opposes the motion of objects Which are in contact |
| sub Duction | he process by which one plates of the lithosphere sink and slides under another | rift valley | the valley formed by s diverging plate boundary |
| ocean trench | long deep formation on the plates floor that develops where two tectonic plates are moving toward each othelr and one is moving under the others |
