1. Compared to Earth’s continental crust, Earth’s mantle is (1) thinner and more dense (2) thinner and less dense (3) thicker and more dense (4) thicker and less dense

3. If an object is “regular” (like the classroom), then volume can be calculated… V = L x W x H V = cm x cm x cm = cm 3

4. If an object is liquid (like water), then volume can be measured… V = mL

5. If an object is “irregular” (like a rock), then volume can be measured by water displacement…

6. According to an electronic balance, this rock has a mass of 13.7 g. What is the rock’s density? mL

7. Why does the oceanic crust sink beneath the continental crust? (1) The oceanic crust has a greater density. (2) The oceanic crust is pulled down by Earth’s magnetic field. (3) The continental crust is stronger. (4) The continental crust is pulled upward by the Moon’s gravity. The diagram shows 2 pieces of Earth’s crust pushing into each other. It appears that the oceanic crust is sinking below the continental crust at this location.

8. What is the density of mineral sample A? (1) 12.0 g / cm 3 (3) 4.0 g / cm 3 (2) 3.0 g / cm 3 (4) 0.33 g / cm 3

9. What is the density of mineral sample B? (1)12.0 g / cm 3 (3) 4.0 g / cm 3 (2) 3.0 g / cm 3 (4) 0.33 g / cm 3

10. 13.5 g / mL Three materials are dropped into a container of mercury (13.5 g / mL ). The first material is water (1 g / mL ). The other two are shown below the picture. m = 15 g V = 18 mL m = 78 g V = 5 mL What order will they take? water
