He answer is False
hope this helps XD
Answer:
The crust broke up because of the convection currents, formed tectonic plates, and is slowly pushed on the surface until it collides with another plate and subducts.
Explanation:
This image gives us the basics of how the plate tectonics theory works. The material in the upper mantle is cooler and denser than the material in the lower mantle, so it drops down and it pushes the hotter and less dense material up. This creates a circular motion in the mantle, and this motion creates enormous pressure on the crust above it and breaks it up.
As the crust is broken up, magma is rising constantly for millions of years, so the new magma pushes the old solidified one further away. This also pushes two pieces of crust away from each other. As the crusts move away, they eventually collide with another plate, and either gradually merge with it, or a subduction zone is created. In the latter, the crust moves below another crust and into the mantle, where it gets melted and recycled.
The second largest continent is Africa , the worlds largest desert is Sahara desert and the worlds longest river is amazon
A LANDSLIDE is a type of mass movement that occurs with a thin block of soil, rock and debris separates from the underlying block.
Answer:
Plate Tectonic theory
Explanation:
Plate tectonics is based on continental drift, and seafloor spreading the three pieces of evidence that support this are those given by Alfred Wagner
As the Jigsaw fit between continents that were one at some point in time.
As the polar wandering or the flight to poles i.e how continents are drifted way to poles by forces of wind.
Presence of the same flora and fauna and glacial valley formation that were once a part of the same continent of Pangea and Gondwana.
The hypothesis ultimately got replaced by seafloor spreading as the drawbacks of drift theory which would not give sufficient evidence for the spreading away of continents. Earth's tectonic forces and internal sources of energy i.e heat produced by radioactive decay was not emphasized and Alfred's continuous orogeny could not have been possible.
