TRUE OR FALSE -- if false, replace the word that's false and write the new sentence.

7. The gravitational force increases with increasing mass and increasing distance.

8. The oceanic crust is thinner and denser than the continental crust.

9. The geothermal gradient in the crust is 1oC/km and within the mantle it is 25oC/km.

10. The presence of a low velocity zone is attributed to partial melting in the mantle.

11. Low confining pressures and low temperatures favor folding over faulting.

12. Long-range earthquake forecasts are based on the premise that earthquakes are repetitive or

cyclical, like the weather.

13. The mantle is made up of an ultramafic rock called basalt.

14. The average density of the Earth is about 3.0 gm/cm3.

15. Horizontal tensional forces form normal faults.

7. false

The gravitational force increases with increasing mass and decreasing distance. ( g = G*M/R^2)

8.true

9.false

geothermal gradient is 25 0c /km at crust .

10. true

11.true

12. false

Long-range earthquake forecasts are based on the premise that earthquakes are repetitive.

13. false

The mantle is made up of an ultramafic rock called peridotite.

14.false
