True or false Tectonic plates are moved by movement of gasses?
False
Which way do the plates move if its a convergent boundary?
towards each other
True or false, the mantle sits below the outer core.
False

Whats it called where two plates meet?
Plate Boundries
Which plate boundaries most commonly cause earthquakes? and which way are the plates moving?
Transform and they slide past one another.
What is the more technical name for the earths crust? it starts with L
Lithosphere
Explain how convection currents cause continental drift
When the convection currents move the plates, this makes the continents and oceans ontop move and shift over the earth.

Give an example of a constructive boundary and what type of plate boundary it is.
Convergent and this is when it creates something on the earth such as mountains, an example could be the Himalayas.
What material is mantle made out of?
Magma/molten rock
Explain convection currents, what are they?
Convection currents are like invisible rivers of heat flowing within the Earth's mantle. When parts of the mantle get heated, they become less dense and rise upwards. As they rise, they cool down and become denser, causing them to sink back down. This continuous cycle of rising and sinking creates a circular motion known as a convection current. These currents play a crucial role in driving the movement of tectonic plates and shaping the Earth's surface over time.
What does SULTAN stand for?
Scale, Units, Labeled Axis, Title, Axis, Neatness
What 2 plates does NZ sit on?
