Which statement correctly distinguishes weathering from erosion?

Weathering breaks rock down in place; erosion removes the loosened products

Freeze-thaw weathering breaks rock apart because

water expands by about 9 percent when it freezes in cracks

clay minerals plus soluble cations

long-distance transport with abrasion

a current loses energy and drops coarse grains first, then fine

periodic exposure and drying out

radioactive decay of uranium, thorium and potassium-40

25 to 30 degrees Celsius per kilometre

the mantle is solid but ductile and flows slowly over millions of years

Because the temperature reached is far below the melting point of silicate rock
