Odivergent boundary
transform boundary
O convergent boundary

1 Answer

  • Answer: New land is formed when magma pushes up from the mantle and cools at a divergent boundary.

    Explanation:

    A divergent boundary is a type of plate boundary where two tectonic plates are moving away from each other. As the plates move apart, magma from the mantle rises up and fills the gap, eventually solidifying into new land. This process is known as sea floor spreading, and it is responsible for the creation of new oceanic crust.

    Convergent boundaries, on the other hand, are plate boundaries where two tectonic plates are moving towards each other. At these boundaries, one plate typically sinks beneath the other in a process known as subduction. This can lead to the formation of volcanoes and mountain ranges, but it does not result in the creation of new land.

    Transform boundaries are plate boundaries where two tectonic plates are sliding past each other in opposite directions. At these boundaries, there is no creation of new land, but there can be significant deformation and earthquakes as the plates grind against each other.
