earth's layers and movt

This is an example of -

• convergent
• divergent
• transform

What causes the tectonic plates to move?

• convection of magma
• the earth's magnetic field
• the earth spinning
• earth's gravitational pull

The movement of plates at a divergent boundary

• move towards each other
• slide past each other
• move up and down
• move away from each other

Sea floor spreading happens at what type of boundary

• Divergent
• Convergent
• Transform
• Mountainous

What is a major geological event that occurs when plates shift suddenly and release stored energy?

• earthquakes
• volcanic eruptions
• divergent boundaries

Look at the drawing shown.  What likely happens when two continental plates collide?

• An ocean trench forms.
• Earthquakes occur.
• Sea-floor spreading occurs
• Folded mountains form.

The layer of Earth that is found directly below the lithosphere is called the -

• asthenosphere.
• inner core.
• outer core.
• crust.

The Himalayas in Asia are an example of what type of plate boundary?

• divergent
• continent-to-continent convergent
• ocean-to-continent convergent
• transform

What forms at a divergent boundary?

• mid-ocean ridges
• mountains
• earthquakes
• only volcanoes

What is a subduction zone?

• where plates move into each other
• where plates are moving away form each other
• where plates move past each other
• area where plate slips under another plate
