crust

mantle

outer core

inner core

Question 22

22.

Particles transfer energy easily upon collisions because they are packed relatively close together. Which is the most likely part of the Earth where this takes place?

crust

mantle

outer core

inner core

Question 23

23.

Choose all statements below that CORRECTLY explain why convection currents occur in the mantle causing plates on the Earth’s crust to move.

Radioactive decay from the Earth’s mantle drives the movement of fluid to rise up and down based on density

Warm particles in the fluid like mantle rise towards the crust while the cooler more dense particles fall

Earth’s sunlight allows the fluid from the mantle to rise and fall

Thermal energy is transferred from colder more dense particles to warmer less dense particles in the mantle

The inner core experiences high temperatures and pressures due to the radioactive reactions and transfer this thermal energy to the outer core and mantle
