The image shows two tectonic plates moving away from each other. What must have caused the plates to move apart from each other?

• the gravitational pull of the Moon

• convection currents in the mantle

• increase in the Earth's magnetic field

• decrease in the weight of the tectonic plate

The images show the position of landmasses on Earth from about 225 million years ago to the present day. What must have caused the changes over time?

• Ocean tides pushed them apart.

• Gravity from nearby planets pulled them.

• Heavy rain eroded the land which caused movement.

• Earth's internal energy created convection currents which resulted in movement.

Magma rises from the earth’s interior and erupts on the surface in volcanoes. What causes this lava motion?

• heat from sunlight

• magnetism from the Earth's core

• the gravitational pull from the Moon

• convection currents within the mantle

What causes the formation of oceanic trenches?

• the presence of salt in ocean water

• the movement of fish and other marine life activities

• the weight of water pushing down on the ocean floor

• the movement of tectonic plates that are driven by convection currents

In terms of tectonic plates, what do the red arrows represent in the diagram?

• The arrows represent energy transfer via conduction, which contributes to the extremely hot temperatures of the Inner Core.

• The arrows are showing the movement of a trench, which results from less dense and cooler rock returning to the Outer Core.

• The arrows represent convection currents, which contributes to the movement of tectonic plates.

• The arrows show how cooler rock from the outer core is rising towards the lithosphere, thus causing tectonic plate movement.
