Answer:
were introduced into American geography in the 1920s by Carl Sauer
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.
Answer:
Conduction, radiation and convection
Explanation:
Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface.
As the warmed air rises, cooler air moves in to take its place. This is called convection, the energy transfer through the movement of matter.
Ships can transit between the Atlantic and Pacific Oceans using the Panama Canal.
