Below are sample questions representative of the exercises included on this worksheet and related 9.68 Earth's Internal Heat and Convection skill assessments:

Problem 1Difficulty: Mastery

Which answer gives the best overall explanation of Earth's internal heat and convection?

AThe mantle cannot move because solid rock never deforms under any conditions

BRadioactive decay directly pushes plates sideways without changing thermal energy or density

CEarth's leftover formation heat and radioactive decay maintain internal temperature differences; density changes drive slow mantle flow that helps move material and plates

DEarth's mantle moves because sunlight melts the crust each day and makes continents float on water

Solution & Explanation:A complete explanation connects internal heat sources, temperature and density differences, convection of mantle material, and long-term movement inside Earth.

Problem 2Difficulty: Mastery

A student claims, 'More radioactive isotopes always mean faster plate motion.' Which response is most accurate?

ARadioactive isotopes cannot affect internal heat at all

BMore radiogenic heat can strengthen convection, but viscosity and forces also matter.

CMore isotopes automatically remove all mantle resistance

DPlate motion depends only on wind speed

Solution & Explanation:Internal heating matters, but plate motion results from several interacting properties and forces, so the claim is too simple.

Problem 3Difficulty: Mastery

Use the upwelling model. Why is partial melting shown beneath the ridge rather than throughout the entire mantle?

AAll mantle material is liquid everywhere

BRising mantle stays hot while pressure decreases, so only some material melts

CPartial melting is caused by ocean waves grinding rock

DThe ridge receives enough sunlight to melt the core

Solution & Explanation:Decompression melting occurs when hot mantle rises to lower pressure. It creates partial melt without making the whole mantle liquid.
