new ocean crust
Explanation:
Each cycle of spreading and intrusion of magma during sea floor spreading results in the creation of new oceanic crust.
At a divergent margin, new oceanic crust is being created.
- Most of these centers are called constructive margin due to the creation new crust here.
- The intruding magma welling up as a result of the splitting crust introduces new material to crust.
- This pushes on the old one causes a ridge build up at the margin.

Much of Earth's water is thought to have come from asteroids impacting the planet early in its history. Image via NASA/Don Davis. The surface of the very young Earth was initially an ocean of magma. Hydrogen and noble gases from the solar nebula were drawn to the planetary embryo, forming the first atmosphere.
I would like to think it's the Middle East and North Africa, which is a part of Africa, Asia, and to some extent, Europe.
Answer:
I think Africans were enslaved in the American because they were demand inferior
Explanation:
If you need anything els im here! :)
The correct answer is - d. colder and denser.
The main differences between the surface currents and deeper currents are the temperature and density, and that actually decides their position in the water, on the surface, or deeper.
The surface currents are warmer, and because they are warmer the molecules are much more loose, so the density is lower, which in return makes it easier, thus it is in the surface.
The deeper currents are colder, and because they are colder the molecules are much closer and more concentrated, so the density is higher, which means that they are heavier, thus fall deeper below the easier currents.
