Question

Which of these types of volcanic settings produced 70% of the earths surface?

a)subduction zones
b)hot-spot volcanoes
c)mid-ocean-ridges volcanoes
d)continental rifts

Answer 1

Mid-ocean ridges volcanoes produced 70% of the Earth's surface.

Step-by-step explanation:

The type of volcanic setting that produces 70% of the Earth's surface is mid-ocean ridges volcanoes. Mid-ocean ridges are long undersea mountain ranges formed by lava rising from Earth's mantle at plate boundaries. They are responsible for the majority of volcanic activity on the Earth's surface. Lava rises to the surface along these ridges and solidifies to form new crust, gradually expanding the size of the ocean basins.
