undersea volcanoes are often formed by what boundary

The ______contains the asthenosphere and the lower mantle.

What happens when oceanic plates collide

What is oceanic crust mainly composed of

Who proposed continental drift

____are formed at divergent and converging boundaries

The lithosphere is part of the crust and upper mantle.

How it possible that convection happens in the Earth, despite the mostly solid asthenosphere?

The fact that similar fossils are found on both sides of the ocean is evidence of

a plate boundary where two plate spread apart to form mid ocean ridges, etc.

Which is not evidence for Continental Drift

What process happens at the trench?

Pressure decreases as depth increases within the layers of the Earth.

a boundary where to plate push together to form trenches, etc.

Bands of magnetic material in the sea floor that have opposite poles, can provide evidence for

Rocks are younger at ridge than further away

New oceanic lithosphere forms as a result of
