Review Ch 3 Models of the Earth

Where does the north end of a compass needle point?

• toward the North Pole
• toward the geomagnetic north pole
• toward the South Pole
• toward the equator

The distance measured by a degree of longitude

• is always about 111 kilometers.
• increases as you move from the equator toward the poles.
• decreases as you move from the equator toward the poles.
• is constant.

What is true about the equator?

• It is the only line of latitude that is a great circle.
• It is the same as the prime meridian.
• It is a line of longitude.
• It falls at latitude 60°N.

How are latitude and longitude measured?

• in kilometers
• in miles
• in degrees, minutes, and seconds
• in hours, minutes, and seconds

What is the prime meridian?

• the only line of longitude that is also a great circle
• the international date line
• the only line of latitude that is also a great circle
• the line of longitude designated as 0°

What does color indicate on a topographic map?

• elevation
• direction
• geologic unit
• type of feature

Geologic maps are designed to show

• various colors that represent political boundaries.
• the distribution of rocks and faults, folds, and other structures.
• types of rocks, minerals, and soil.
• elevation, relief, and other surface features.

What is latitude?

• the angular distance north or south from the equator
• the linear distance north or south from the equator
• the angular distance east or west from the prime meridian
• the linear distance north or south from the prime meridian

What is longitude?

• the linear distance north or south from the prime meridian
• the angular distance east or west from the prime meridian
• the angular distance north or south from the equator
• the linear distance east or west from the equator

Latitude and longitude can locate a place on Earth’s surface by describing its position in degrees, minutes, and seconds

• east or west of the prime meridian and north or south of the equator.
• north or south of 180° latitude and east or west 180° longitude.
• east or west of the international date line and north or south of the poles.
• north or south of the prime meridian and east or west of the equator.
