ENVS 104 Week 3

According to your mapping exercise, fault zones like the Balcones Escarpment in Austin, Texas are:

All of the above.

Which prehistoric continents in the geologic past were all one massive landmass called "supercontinents?"

All of the above.

The acceleration due to gravity is 9.8 meters per second squared (32 feet per second squared), which is referred to as 1.0 g and is used as a comparative unit of measure. Earthquake accelerations have never been measured in excess of 1.0 g.

False

Transform faults have mostly vertical displacement rather than horizontal displacement.

False

When the Earth shakes, it releases energy in seismic waves, some of which pass through the whole body of the planet (body waves) and some of which propagate only near the surface (_______ waves).

Rossby

_________ waves are transverse waves that propagate by shearing or shaking particles in their path at right angles to the direction of advance.

Both Love and S

During the time between the disappearance of Rodinia and the reappearance of Pangaea, over 90 percent of all species on the Earth went extinct - a loss of life greater than the extinction of dinosaurs, 65 million years ago.

True

The shallower the hypocenter, the more P- and S-wave energy will hit the surface, thus putting less energy into Rayleigh waves.

True

To describe the location in three-dimensional space of a deformed rock layer or a fault surface, geologists make measurements known as dip and strike.

True
