the oldest sections of the continental crust are breaking apart. Scientists have argued that the Earth’s crust has shifted to change its positions as well as the terrain of the Earth.

Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...

And like an eggshell, the crust has cracked and split into many different pieces called tectonic plates. These plates can be oceanic, meaning they're found mainly under the ocean, or continental ...

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens ...

By determining which ice sheets melted to create a colossal increase in sea levels 14,500 years ago, scientists hope to ...

Situated on the west coast of the island of Newfoundland, the park provides a rare example of the process of continental drift, where deep ocean crust and the rocks of the earth's mantle lie exposed.

Beneath the central and southern Sierra Nevada, seismic signals confirmed a slow-motion detachment of deep crust, matching theories of global-scale continental evolution over geologic time.
