Plate Tectonics

What causes the motion of the plates?

• Convection in the outer core

• Magnetic reversals

• Energy from the Sun

• Convection in the mantle

What is a divergent plate boundary?

• A boundary between two plates that are moving apart
• A boundary between two plates that are crashing together
• A boundary between two plates that are sliding past each other
• A boundary between two plates that are not moving

What feature forms near divergent boundaries between two pieces of oceanic crust?

• Mid-ocean ridge

• Non-volcanic mountain

• Continental rift valley

• Trench

What feature forms near divergent boundaries between two pieces of continental crust?

• continental rift valley

• non-volcanic mountain

• mid-ocean ridge

• canyon

What is seafloor spreading?

• continents spreading as ocean crusts collide

• mountains being melted by volcanoes

• ocean get smaller and magma sinks creating in locations where ocean plates are moving towards each other

• ocean spreads and magma rises to fill in gaps creating a mid-ocean ridge in locations where ocean plates are moving away from each other

What process takes place where trenches are found?

• convergent boundaries

• subduction

• earthquakes

• mountain ranges

What process is occurring in this diagram?

• plates of eggs

• diverging

• subduction

• transforming

What type of event will occur at this boundary?

• Earthquake
• Volcano Eruption
• Tornado
• Mountain Building
