Plate Tectonics

1.  What can tectonic plates form when they converge?

• Mid-ocean ridges
• Rift Valley
• fault line
• Mountains

What is a Subduction zone?

• When an oceanic plate moves under a continental plate
• When two plates slide by each other
• When two plates move away from each other.
• When an oceanic plate moves under a continental plate.

What can a divergent boundary form?

• Landslide and mountain
• Trench and volcano
• Ridge and rift valley
• Earthquakes and volcanoes

What types of plates form a subduction zone?

• Continent-Ocean
• Continent-Continent

An example of an active collision boundary is

• The Hawaiian islands
• The Rocky Mountains
• The Mid-Atlantic Ridge
• The Himalayan Mountains

An example of a divergent plate boundary is

• The Juan De Fuca and Morth American plate boundary
• The Marianas Trench
• The African Rift Valley
• The Ring of Fire

A trench is formed when?

• An ocean plate gets subducted under another ocean plate
• There is a mudslide
• A volcano erupts
• Two continental plates collide

When do P,S, and L waves begin?

• When a Tsunami happens
• Then there is elastic deformation and rocks break
• When plastic deformation causes bending.

What is a collision boundary?

• When two continental plates collide to form mountains
• When two plates slide by each other
• When two plates move away from each other
• When an oceanic plate moves under a continental plate

An example of an active subduction zone and formation of a trench is?

• Ring of Fire with Marianas Trench
• The Mid-Atlantic Ridge
• The African Rift Valley
