Plate Tectonics Basics (6th Grade)

Front

What is the primary cause of the movement of Earth's tectonic plates?

Back

Convection.

Front

What are the two types of Earth's crust?

Back

Oceanic and continental.

Front

What type of plate boundary occurs when two plates collide and one plate slides under the other?

Back

Convergent with Subduction.

Front

What is the name of the boundary where tectonic plates move away from each other?

Back

Divergent.

Front

Which of the following does NOT provide evidence for the Theory of Plate Tectonics: different types of rocks found on different continents, fossil distribution, or sea-floor spreading?

Back

Different types of rocks found on different continents.

Front

What is the process called when one tectonic plate moves under another?

Back

Subduction.

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.

Front

What is the significance of the mid-ocean ridge in plate tectonics?

Back

It is a divergent boundary where new oceanic crust is formed.

Front

What type of boundary is characterized by plates sliding past each other?

Back

Transform boundary.

Front

What evidence supports the theory of plate tectonics related to fossil distribution?

Back

Similar fossils found on widely separated continents suggest they were once connected.
