How do volcanoes form at divergent boundaries?

Geography
1 answer:
Dmitriy789 [7]3 years ago
8 0

The divergent plate boundaries are the places where the tectonic plates move away from each other. As they move part, which is actually driven by the convection currents in the mantle, they leave a gap between them of very thin and cracked crust. The convection currents manage to push the magma up with easy through this gap. As the magma pushes upward, it reaches the ocean floor, where the temperatures is significantly lower and it quickly cools off and forms new igneous rocks, or rather new crust. Since the magma is constantly rising and constantly making new crust, the new crust is pilling up, forming a mid ocean ridge with intense volcanic activity. Eventually, the rising magma will manage to come out on the surface and create volcanic islands, thus a chain of volcanic islands, which can even result in the formation of new large land of mass.

katovenus [111]

By the end of the 19th century, most of Europe's colonies were in Africa.

Explanation:

Several of the European countries managed to become colonial powers. They managed to colonize very large portions of the world, and the majority of the continents were subject to the colonization. The European colonies were located in:

  • Africa
  • Asia
  • Australia

In the late 19th century, things have changed though, and the Europeans had lost their colonies in North America, South America, and the Caribbean, except fro the Guyanas. On the other side, the colonies increased significantly in the other parts of the world, such as Africa and Asia. While there were solid amount of colonies in Asia, it was Africa that was the colonization hot spot in this period, with all of the continent being colonized by some of the European countries.

The biggest objection to Wegener's continental drift hypothesis was _____.
Ann [662]

Answer:

a) there was no evidence to support it

Explanation:

Wegener noticed while looking at the maps that some parts of the continents, especially South America and Africa, seem to match up perfectly. This led him to think that maybe the continents in the past were actually connected, but because of some force they moved apart. He went out public with his hypothesis, but it was largely rejected, and he was laughed at and ridiculed, as the scientists thought that there's no force that can move the continents. Wegener didn't stop there, and he continued to look for clues, and finally managed to find some clues at the topography of the Atlantic Ocean. He noticed that the mid-ocean ridge is the highest, but as you move away from it, the sea mounds are becoming flatter and lower, thus a sign of erosion, and he actually turned out to be right.
