Adivergent plate boundary is a boundary at which two tectonic plates move away from each other. as the plates move apart, magma rises upward between them and erupts onto the ocean floor as lava. this lava cools quickly to form solid rock. over time, these hardened lava flows build up on top of each other and are uplifted by tectonic forces to form mid-ocean ridges. based on this information, what type of rock are mid-ocean ridges made of?

Mid-ocean ridges are made up of Igneous rock k/a Mid-ocean Ridge basalt rock.

Explanation:

The cooling and crystallization of magma and ocean ridges result in the formation of the new crust of igneous rocks. The tectonic plates on the lithosphere layer of  the earth keep moving, a divergent boundary is formed when tectonic plates move which may cause an earthquake or oceanic crust.

Mid-ocean crusts are mid-water mountain ranges formed by plate tectonics. A new seafloor and oceanic lithosphere are formed due to the tectonic plate divergent. This seafloor is made up of igneous rocks.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
