General Geology 1

The point in the bedrock at which an earthquake seems to center is known as its

• anticline

• epicenter

• focus

• fault

Diatrophism refers to which of one of the following? The

• rising and sinking of the earth's surface

• formation of geysers

• erosion caused by wind

• movement of clouds

The fraction of the solid part of the earth that lies beneath water and ice is

• 1/3

• 1/2

• 3/4

• 5/6

The surface of the solid part of the earth consists essentially of huge blocks of rock which sometimes break away and rise or sink. This action is called

• volcanic action

• folding

• faulting

• weathering

Generally speaking, MOST of the world's volcanoes

• lie in belts which are almost identical with the two great earthquake belts

• are roughly at right angles to the earthquake belts

• are in the equatorial regions

• form no particular geographic pattern

All but one of the following statements about artesian wells are true. The EXCEPTION is:

• Artesian well water is usually much colder than ordinary well water.

• The water in artesian wells is drawn from aquifers below an impervious layer.

• Artesian well water is usually harder than ordinary well water.

• The source of the water supply in an artesian well may be hundreds of miles from the well.

When oil spouts from a well as a gusher, it USUALLY does so because

• of the pressure of water beneath the oil or of gas above the oil

• air is pumped into the well

• of the release of great heat

• of the tremendous pressure of subsurface rock layers on the oil

The volcano which was formed in Mexico in 1943 was named

• Popocatepetl

• Mauna Loa

• Paricutin

• Krakatoa

A narrow V-shaped valley is considered by geologists to be

• young

• old

• mature

• between mature and old

As compared with a valley made by a stream, a glacial valley is

• rounded and smooth

• irregular and rough

• irregular and smooth

• rounded and rough
