Question

Where are the newest parts of earth’s crust located?

a) on the tops of mountains on the tops of mountains
b) on plateaus on plateaus
c) at the edges of continents at the edges of continents
d) at mid-ocean ridges

Answer 1

The newest parts of Earth's crust are found at mid-ocean ridges, where divergent plate boundaries allow magma to rise and form new crust.

Step-by-step explanation:

The newest parts of the Earth's crust are located at mid-ocean ridges. These ridges are sites of divergent plate boundaries, where tectonic plates are moving apart from each other. As these plates separate, magma from the mantle rises to fill the gap, creating new crust as it cools and solidifies. Most of these boundaries are found in ocean basins, with an example being the Mid-Atlantic Ridge. The process of new crust formation at mid-ocean ridges is tied to the convection currents in the mantle, which drive the movement of the tectonic plates.

Consequently, the correct answer to the student's question is 'd) at mid-ocean ridges.'
