Sea floor spreading is actually the creation of new oceanic basaltic crust at divergent plate boundaries called mid-ocean ridges. Material from the asthenosphere becomes molten as convection currents cause it to rise toward the thin upraised boundary between plates there. /as it solidifies, it becomes new crust. Because new oceanic crust is being created there, older oceanic crust is being destroyed at trenches, where the colder, more dense oceanic crust is being drawn into the asthenosphere, completing the roughly 200 million year oceanic crust recycling period.THERE ARE ALSO PART OF AN EVIDENCE OF THE MOSTFAMOUS KNOWN SUPERCONTINENT ALSO kNOWN AS THE PANGEA

What is the name of the theory that explains how forces deep within earth can cause ocean floors to spread and continents to more?

The theory is called plate tectonics. It explains how the Earth's lithosphere is divided into plates that move and interact with each other, leading to phenomena like seafloor spreading and continental drift.


Does string theory negate the four fundamental forces?

String Theory does not negate the four fundamental forces, it explains them in another way.


What is the GUT theory?

The GUT theory is a theory that combines three of the four fundamental forces together. The three fundamental forces are the strong nuclear force, weak nuclear force, and electromagnetic force. This theory explains the connection between these forces and if gravity was able to connect with these forces, then we have the TOE (Theory of Everything).


What is the name of the theory that explains how forces deep within earth can cause ocean floors and continents to move?

The theory you are referring to is called plate tectonics. It explains how the lithosphere (Earth's outer layer) is divided into several large rigid plates that move and interact with each other, causing phenomena like earthquakes, volcanic activity, and the shaping of the Earth's surface.


Which theory explains the forces powerful enough to send gigantic plates sliding around the earth?

What theory explains how forces within the planet create landforms?

The theory of plate tectonics explains how forces within the planet create landforms. These forces include the movement of Earth's lithospheric plates, which can collide, separate, or slide past each other, leading to various landforms such as mountains, valleys, and rifts.

Theory that explains changes in Earths crust by internal forces?

The theory that explains changes in Earth's crust due to internal forces is called plate tectonics. This theory describes how the Earth's outer layer is divided into several large, rigid plates that float on the semi-fluid asthenosphere below. The movement and interaction of these plates cause various geological phenomena such as earthquakes, volcanic eruptions, and mountain formation.
