• Continental

• Both are equally dense

• Neither is dense

• Oceanic

What are the 4 main layers of the Earth?

• outer core, inner core, lithosphere, asthenosphere

• crust, mantle, inner core, outer core

• atmosphere, lithosphere, asthenosphere and hydrosphere

• crust, ocean, continental and atmosphere

Which layer of the Earth is responsible for convection currents?

• Outer core

• Crust

• Inner core

• Mantle

What is the main evidence used to support the continental drift theory?

• The number of earthquakes in a region

• The color of the ocean water

• Matching shapes of coastlines and distribution of fossils and rock formations

• The temperature of the Earth's core

What is the main difference between the lithosphere and asthenosphere?

• The lithosphere is rigid and solid, while the asthenosphere is plastic and can flow.
