Tectonic Processes 3

Question 1

4 Layers of Earth:

Answer 1

• Crust
• Mantle
• Outer core
• Inner core

Question 2

What is the difference between oceanic and continental crust/plates?

Answer 2

Oceanic plates: under oceans
Continental plates: carries land

Question 3

What process moves the plates in the mantle?

Answer 3

Convection currents

Question 4

Where are you most likely to find tectonic hazards?

Answer 4

By or on a plate boundary

Question 5

Which direction do conservative plates move in?

Answer 5

Side my side in same or opposite directions

Question 6

What hazards are found at a convergent plate boundary?

Answer 6

Earthquakes, volcanoes and tsunamis

Question 7

How are volcanoes formed at a divergent plate boundaries?

Answer 7

• Plates separate, magma fills the gap, gradually building up layers of volcanic rock under the ocean to form a volcano.

Question 8

What scale is used to measure the energy released by earthquakes?

Answer 8

Richter scale

Question 9

How do earthquakes form at a convergent plate boundary?

Answer 9

One plate slides beneath another, creating friction. When the built-up pressure overcomes this friction, it releases energy as an earthquake.

Question 10

What are the main features of a volcano?

Answer 10

• Main vent
• Crater
• Magma chamber
• Secondary cone
• Layers of ash and lava.
