Y7 Plate boundaries

What are plate boundaries also called?

• Plate junctions

• Plate centers

• Plate margins

• Plate crossings

What happens at divergent (constructive) plate boundaries?

• Plates collide and create mountains

• Plates slide past each other

• Plates are destroyed

• Magma rises and creates new crust

Where do most constructive boundaries appear?

• In the atmosphere

• At the bottom of the sea

• Inside the Earth's core

• On land

What natural hazard is commonly found at constructive boundaries?

• Tsunamis

• Volcanoes

• Powerful earthquakes

• Landslides

What is subduction?

• When an oceanic plate is forced underneath a continental plate

• When two plates slide past each other

• The cooling of magma to form new crust

• The process of mountains forming

What causes volcanic eruptions at destructive boundaries?

• The separation of two tectonic plates

• The collision of two continental plates

• The sliding of plates past each other

• Water and other materials melting through the crust

What is created at collision boundaries?

• Deep sea trenches

• New ocean basins

• Volcanic islands

• Mountain ranges

Why don't volcanoes occur at conservative boundaries?

• Because the plates are moving apart

• Because there is no magma rising up underneath

• Because the plates collide and create mountains

• Because the plates are destroyed

What happens when tectonic plates at conservative boundaries finally move again after being stuck?

• A tsunami is generated

• A new mountain range is formed

• A volcanic eruption occurs

• The ground shakes (earthquake)

Which plates are involved in the formation of the Himalayas?

• The Antarctic and Australian plates

• The African and South American plates

• The Indian and Eurasian plates

• The Pacific and North American plates
