Tectonic Plates Worksheet

Why is it important to describe what happens at plate boundaries?

• To understand the tectonic hazards that occur.

• To learn about animal migration.

• To study weather patterns.

• To predict volcanic eruptions only.

Which type of plate boundary is associated with one plate being forced under another, often causing volcanic activity?

• Destructive

• Conservative

• Constructive

• Collision

What is released when the rock fractures at a conservative plate boundary?

• Water

• Lava

• Waves of energy

• Wind

Which two plates meet at the San Andreas fault?

• Eurasian plate and African plate

• Indian plate and Australian plate

• South American plate and Antarctic plate

In which direction is the Pacific plate moving?

• north-north-west

• south-east

• east

• south-west

What happens at a constructive plate boundary?

• Tectonic plates move apart.

• Tectonic plates collide.

• Tectonic plates slide past each other.

• Tectonic plates stay still.

Which direction does the North American plate move at the Mid-Atlantic Ridge?

• East

What happens where plates diverge?

• New rock forms at the plate boundary

• Mountains are destroyed

• Oceans dry up

• Volcanoes stop erupting

Do earthquakes happen at constructive plate boundaries?

• Yes

• No
