Endogenous Process Ice breaker quiz (pre-test)

Why does radioactive decay play a very important role in earth’s internal heat?

• Radioactive element can be found anywhere in the planet.

• When radioactive element decays, it produces heat.

• Spontaneous nuclear disintegration of radioactive elements produced thermal energy.

• All of the above

How does convection in Earth’s mantle affects the formation of landmass like volcano and mountain?

• Heat tries to escape in the interior of the earth.

• Collision and separation of tectonic plates happens due to the slow motion of convection cells.

• When warm material in the mantle rises up to the surface (ground), it will cool and sink, these cooled materials will eventually be turned into landmass.

• All of the above

What is produced by the radioactive decay of isotopes in the mantle and crust?

• radiogenic heat

• primordial heat

• superheating

• heat from the sun

This refers to the heat left over from the formation of the Earth?

• radiogenic heat

• primordial heat

• superheating

• heat from the sun

Which of the following is the outermost layer of the Earth?

• crust

• core

• discontinuity

• mantle

Which of the following stores magma and located in a region just beneath the crust all the way to the core?

• crust

• outer core

• inner core

• mantle

What heat transfer of fluid in the Earth’s interior results to the movement of rocky mantle up to the surface?

• convection

• conduction

• insolation

• radiation

What refers to the shaking of the surface of the Earth resulting from a sudden release of energy caused by a convection current?

• earthquake

• volcanic eruption

• storm surge

• hurricane

The process of convection is not limited to liquid but also to gas.

• True

• False

Radiation only happens between the Earth and the sun.

• True

• False
