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

Identify all the statements below that are TRUE 

The particles kinetic energy increases from 7 minutes to 25 minutes

The particles potential energy increases from 7 minutes to 25 minutes

The particles are loosely attracted to each other at 35 minutes

The forces between particles are breaking apart from 34 to 36 minutes

The particles gain and transfer energy to each other the duration of the experiment

The energy from particles is destroyed from 7 to 25 minutes

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
