17. Choose the answer that best describes the geologic process that contributes to the formation of fault-block mountains. A)The Earth's crust is pushed together which tilts layers of rock on their side producing steep scarps.

B)The Earth's crust is pulled apart creating deep folds and then pushed together generating steep scarps.

C)The Earth's crust is pushed together which forces up blocks vertically creating steep scarps.

D)The Earth's crust stretched from swelling underneath and vertical movement by blocks generates steep scarps.

B.

Explanation:

Have a great day! And good luck

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
