ES Hmwk; Earthquakes

The landscape shown in the following diagram is an area of frequent earthquakes. This landscape provides evidence for

• converging convection cells within the rocks of the mantle

• density differences in the rocks of the mantle

• movement and displacement of the rocks of the crust

• differential erosion of hard and soft rocks of the crust

Which statement about Earth's crust in NYS is best supported by the many faults found in the crust?

• the crust has moved in the geologic past

• the crust has been inactive throughout the geologic past

• new faults will probably not develop in the crust

• an earthquake epicenter has not been located in the crust

Recent volcanic activity in different parts of the world supports the inference that volcanoes are located mainly in

• the centers of landscape regions

• the central regions of the continents

• zones of crustal activity

• zones in late stages of erosion

Where do most earthquakes originate?

• within Earth's outer core

• along specific belts within the crust

• randomly across the entire Earth's surface

• evenly spaced along the Moho interface

Earthquakes generate primary waves and secondary waves. Compared to the speed of the secondary waves in a given Earth material, the speed of the primary waves is

• always slower

• always faster

• always the same

• sometimes faster and sometimes slower

The separation time between the arrival of primary and secondary waves is

• greatest at station G

• greatest at station D

• greatest at station E

• the same at all stations

If the method illustrated by the diagram is used to locate the epicenter of an earthquake, it appears unlikely for an INDIVIDUAL observatory operating independently to determine the

• direction to the epicenter

• distance to the epicenter

• distance to an epicenter under the ocean

• interval between the initial and subsequent seismic waves

The time lapse between the arrival of the P-waves and S-waves on ONE recording of seismic waves can be used to determine the

• magnitude of an earthquake

• exact location of the focus

• exact location of the epicenter

• distance to the epicenter

You record evidence of an earthquake on your seismograph. What information about the earthquake's epicenter can be determined from your seismograph ALONE?
