3.1 Introduction to Earth

What system is used to describe location on Earth's surface?

• Altitude and attitude

• Latitude and longitude

• Coordinate and elevation

• Distance and direction

What does the equator represent in the latitude system?

• The line at 90° latitude

• The line at 0° latitude

• The line at 45° latitude

• The line at 180° latitude

If a location is at 10° N latitude, how is it positioned relative to the equator?

• 10 degrees South of the Equator

• 10 degrees East of the Equator

• 10 degrees North of the Equator

• 10 degrees West of the Equator

How much farther from the equator is a location at 50° N compared to one at 10° N?

• 5 times farther

• 4 times farther

• The same distance

• 40 times farther

What would 10° S represent in terms of location?

• 10 degrees North of the Equator

• 10 degrees South of the Equator

• 10 degrees East of Greenwich

• 10 degrees West of Greenwich

Lines of longitude are centered on which location?

• Paris, France

• Washington, D.C., USA

• Greenwich, England

• Beijing, China

What does 50° E indicate?

• 50 degrees North of the Equator

• 50 degrees South of the Equator

• 50 degrees East of Greenwich

• 50 degrees West of Greenwich

If a location is 10° W, it is how many degrees west of Greenwich?

• 10 degrees

• 20 degrees

• 50 degrees

• 100 degrees

What is the most common tool used to describe direction?

• Map

• GPS

• Compass
