The theory of Convection and Continental drift show that earth's
surface beneath the ocean is dynamic.
What is earth composed of ?
- The Earth is actually composed of three stacked spheres. The Earth's core is made up of a mass of extremely heated iron and nickel.
- The mantle is composed of components that are abundant in iron, magnesium, and calcium, and is a less dense and significantly larger intermediate sphere.
- The crust, which is the thinnest layer, is made up of lighter rocks.
- The earth's interior is heated and under a lot of pressure, which causes it to transfer a lot of its internal heat through a process known as "convection." Hot materials rise, move laterally, cool, and finally fall in a cycle through convection.
- One of the earliest hypotheses put up by geologists for how continents might migrate through time is called continental drift. The science of plate tectonics has now supplanted the theory of continental drift.
