A geologist is studying a rock that is half a meter long, 325 centimeters wide, and 150 centimeters tall. What is the volume of this rock?

You need to determine the volume of a rock, but the rock in question has an irregular shape, so the standard volume equation will not work. Which of the following lab tools can be used to determine the volume of the rock?

Which two observations help constrain the dimensions of Earth's core and mantle?

What does the wobble of Earth's rotation axis tell us?

How do we know that the radius of Earth's core has to be at least 3100 km?

How do we know that the radius of Earth's mantle has to be at least 1771 km?

How do we know the actual dimensions of Earth's core and mantle?

Determine how much a block sinks in water. The density of the block is 0.8 g/cm3, its mass is 2 cm, and the volume is 8 cm3. The density of the water is 1.0 g/cm3. How much of the block's mass is below the water surface?

Select the correct statements below about an iceberg with a density of 0.917 g/cm3 that is submerged in ocean water with a density of 1.025 g/cm3.

Part complete What kind of tectonic boundary would be evidenced by down-dropped blocks of rock and shallow-focused earthquakes?

Part complete You are visiting Key West, Florida. Which tectonic plate are you on, and what is the nearest adjacent plate?

Which of the following evidence does NOT support plate tectonics?
