Chapter 10 Plate Tectonics

Any trace of an ancient organism that has been preserved in rock

A collision between two pieces of continental crust at a converging boundary produces a

Alfred Wegener evidence of landforms, fossils, and climate supported sea-floor spreading.

What type of boundary is pictured below

When 2 continental plates collide what is the result

What type of boundary is pictured below

A rift valley forms at a

The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle

According to Wegener's hypothesis of continental drift

Geological theory that states that pieces of Earth's lithosphere are in constant, slow motion

Old oceanic crust is more dense than new oceanic crust because it is

What type of boundary is the picture below

Most geologists think that the movement of Earth's plates is caused by

What is Pangaea?

The place where two plates come together is known as a

In sea-floor spreading, molten material rises from the mantle and erupts

The lithosphere is broken into sections called

What technology did scientists use in mid-1900's to map the mid-ocean ridge?

What is the process that is happening at the deep-ocean trench.
