Convergent Plate Boundaries

Convergent Boundaries

Plates Collide

Earth is Plated

• Plates - Large Pieces of Rock

• Earth's Crust is Made of Many Plates

Plates "Float" on Mantle

• Magma (Melted/Molten Rock) in the Mantle

• Magma Flows in Currents in the Mantle

Multiple Choice

Earth's crust is made of one solid piece of rock.

• True

• False

Multiple Choice

The place where two plates collide is called a _____________ boundary.

• convergent

• divergent

• transform

• magma

Subduction Zone

• Dense Oceanic Plate Pushes Down & Melts as It Sinks Into the Mantle

• Less Dense Continental Plate Pushes Against & Bends, Breaks the Rock to Build Mountains

Subduction Zone Landforms

• On Land: Ring of Fire - Mountains & Volcanoes

• In Oceans: Trenches & Island Arcs

Deep Ocean Trenches

• Deepest Spots on Earth

• Mariana Trench Deepest of All

Ring of Fire (Video)

• Subduction Zones Around Pacific Plate

• Many Volcanic Mountains, Island Arcs

Multiple Choice

What deep ocean surface feature is created at the place where the oceanic plate pushes under the continental plate?

• mountain

• volcano

• trench

• island arc

Multiple Select

Which land surface features are created at a subduction zone?

• island arc

• mountains

• trenches

• volcanoes

Multiple Choice

Volcanoes are formed at subduction zones when the oceanic plate pushes under the continental plate, melts and magma forms under the mountains on the land.

• True

• False

Multiple Choice

The area of active volcanoes around the Pacific Plate is called

• Volcano Valley

• Ring of Ice

• Volcano Ring

• Ring of Fire

Collision Zone

• Two Continental Plates Push Together

• Rocks Break, Bend, Fold , Push Up

• Tallest Mountains on Earth Form This Way

• Rock at Top of Mountain May Have Ocean Fossils - Rock Was Once Flat Land Under Water and Then Pushed Up Over Time

Himalayan Mountains (Video)

• The Tallest Mountains in the World

• Two Continental Plates Collide
