Earthquakes happen in the Earth’s crust outer core inner core lithosphere

Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates.

OpenStudy (helpz-q):

So i'm thinking the answer would be A because the crust is the outermost layer of earth, right?

OpenStudy (helpz-q):

And in an earthquake the ground cracks

OpenStudy (harrycraig):

Its just due to shifting of tectonic plates , ans is lithosphere

OpenStudy (helpz-q):

Are you sure?

OpenStudy (jalil.h):

Above the asthenosphere is the outermost strength zone, a region where rocks are cooler, stronger, and more rigid than those in the plastic asthenosphere. This hard outer region, which includes the uppermost mantle and all of the crust, is called the lithosphere ("rock sphere"). It is important to remember that despite the fact that the crust and mantle differ in composition, it is rock strength, not rock composition, that differentiates the lithosphere from the asthenosphere. The difference in strength between rock in the lithosphere and rock in the asthenosphere is a function of temperature and pressure. At a temperature of 1300°C and the pressure reached at a depth of 100 km, rocks of all kinds lose strength and become readily deformable. This is the base of the lithosphere beneath the oceans, or, as it is most colloquially termed, the oceanic lithosphere. The base of the continental lithosphere, by contrast, is about 200 km deep.

OpenStudy (helpz-q):

So its the lithosphere? If so then thank you very much

OpenStudy (helpz-q):

could you guys help with one more?

OpenStudy (harrycraig):

yes its told you

OpenStudy (helpz-q):

The theory of continental drift suggests that the continents have moved in the past the continents are slowly moving now the continents have moved in the past and are still moving the continents moved in the past but are not moving now i think its c

OpenStudy (harrycraig):

yup its c
