Identify the structure that makes this pattern of rock layers on the ground surface: parallel stripes, showing bilateral symmetry across a mid-line (hinge), with rock getting older as you move outward from the hinge. 

If you see small, angular fragments of shattered rock along a linear boundary between two masses of rock, you must be looking at:

When the mass of water that an iceberg displaces is equal to the mass of the iceberg, it floats. This is an example of:

Scientists can speculate about the mineral composition of the deep mantle by:

Identify the FALSE statement. Beneath the continents, seismic velocities in the mantle increase with depth because the mantle becomes:
