Tectonic Plate Boundaries & Movements- Molls

Earth's crust is broken up into several large rocky pieces called ...

• plates
• faults
• fossils
• mountains

According to Alfred Wegener's theory of Continental Drift

• The Earth is slowly cooling and more glacial ice is forming

• Earth's surface is breaking down each day

• The continents move continually as the Earth rotates

• The continents appear to have once been joined together as a large, single land mass

As depth beneath the Earth's surface increases, temperature and density

• Both decrease
• Approach Zero
• Both increase
• Stay the same

The proposed cause of tectonic plate movement is:

• Convection Currents
• Rapid cooling of Earth's core

• Conduction Currents

• Seismic Waves

What are the two types of crust

• continental and oceanic
• ocean and upper
• lower and upper
• lithosphere and asthenosphere

This is the layer of the Earth that the plates move on

• Lithosphere
• Asthenosphere
• Crust
• Core

What type of plate boundary is shown in the picture

• convergent

• divergent

• transform

• faults

This is when two plates converge but one slides under the other due to density.

• Uplift
• Subduction
• Trench
• None of the above

What type of plate boundary is shown in the picture?

• folded mountains

• transform

• convergent

• divergent

What plate boundary is shown in the picture?
