What geographic feature would be expected to appear where the star is on this diagram of plate movement?

a volcano

a mountain

a mid ocean ridge

a canyon

Explanation

The answer is "a volcano."

Earth’s crust, also called the Lithosphere, is divided into tectonic plates. These plates move at plate boundaries due to the liquid hot mantle beneath the crust.

Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.

Divergent: extensional; the plates move apart. Spreading ridges, basin-range.

Convergent: compressional; plates move toward each other.

Transform: shearing; plates slide past each other. Strike-slip motion.

At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. Convergent boundaries create mountains, and transform boundaries cause earthquakes as well

shearing motion; plates slide past each other

extensional motion; the plates move apart, spreading ridges, basin-range

compressional motion; plates move toward each other

none of these

The convection currents of magma below these plates would cause what type of motion in the tectonic plates above?

Plate A and Plate B will move away from each other. It is a divergent boundary.

Plate A and Plate B will move away from each other as in a convergent boundary.

Plate A and Plate B will move toward each other. It is a divergent boundary.

At the Mid-Atlantic Ridge, as the tectonic plates move apart, rock is pulled up from depth at the spreading axis and melts as it depressurizes. The molten rock rises to the seafloor and cools to form the layer of crust that paves the ocean floor. This is called "seafloor spreading" and is pictured below.
