The theory of plate tectonics explains many geological events, including
earthquakes, volcanoes, and mountain building. According to the theory of plate
tectonics, which of the following is true?

A.Earth is composed of four layers: the crust, mantle, outer core and inner core.

B.The rocks found on Earth have been changed by natural forces that occur on the
planet.

C.Earth's hard crust is broken into large plates, which keep the continents in fixed
locations.

D.Earth's hard outer shell is broken into large, rigid plates that float atop the
asthenosphere

The crust of the Earth is broken into many pieces called plates. The plates "float" on the soft, plastic mantle which is located below the crust, aka asthenosphere

. According to the theory of plate tectonics, Earth's hard outer shell is broken into large, rigid plates that float atop the asthenosphere

Plate tectonic theory states that the earth solid outer core called the lithosphere is separated into plates and they interact together.

The plate tectonic theory states that this separated plates are constantly moving around. This movement shapes the lithospheric component of the earth.

This movement gives rise to mountain belts, volcanoes due to convergence of this plates.

Diverging plates also gives rise to trenches, subduction zones and other geologic structure.

This outer shell that are broken into large, rigid plates float on top of the buoyant asthenosphere. The asthenosphere is regarded as a semi liquid region.
