Why does oceanic crust subduct under continental crust when the two converge?

• Oceanic crust subducts under continental crusts because they have the same density.

• Oceanic crust subducts under continental crusts because oceanic crust is more dense than continental crust.

• Oceanic crust subducts under continental crusts because oceanic crust is less dense than continental crust.

• Oceanic crust does not subduct under continental crust.

A principle in geology and earth sciences that suggests that the same geological processes observed today have been at work throughout Earth's history. This principle, often encapsulated in the phrase "the present is the key to the past," implies that the processes shaping the Earth's surface, such as erosion, sedimentation, volcanic activity, and tectonic movements, have been operating in a uniform and consistent manner over long periods of time.

• Theory of Catastrophism

• Theory of Evolution

• Theory of Relative Processes

• Theory of Uniformitarianism

Observing the erosion of a mountain over time and concluding that the same natural processes eroding this mountain today were also at work millions of years ago.

• unconformity

The concept that the oldest rock layers are at the bottom of a sequence with younger rock layers deposited on top of them.

• superposition

• rock strata

• core sample
