Introduction to tectonics

1. What is the outer layer of the earth’s structure called? 

• Crust

• Core

• Mantle

• Inner Core

2. How hot can the inner core reach? 

• -2000 degrees

• 2000 degrees

• Over 4000 degrees

• 800000 degrees

The mantle is

• solid (from the pressure)

• liquid (melted from the pressure)

• gas

• semi-solid (molten rock)

The cycles in the mantle that cause the plates to move are called * hint think of today's lesson!

What is the crust split up into? 

• mountains

• tectonic plates

• earthquakes and volcanoes

• countries

What is it called where two plates meet? * hint think red lines on your map last lesson

• plate movement

• danger zone

• plate boundary

• dinner plate

Draw a diagram showing convection currents :)
