What is the imaginary line that circles the Earth at 0 degrees latitude called?
Correct Answer
D. Equator
Explanation
The Equator is the imaginary line that circles the Earth at 0 degrees latitude. It divides the Earth into the Northern and Southern Hemispheres and is equidistant from the North and South Poles. The Equator is the point on Earth's surface where the distance to both poles is equal, making it the widest circumference of the planet.
2.
What is located at 90 degrees north of the Equator?
Correct Answer
E. North Pole
Explanation
The North Pole is located at 90 degrees north of the Equator. It is the point on the Earth's surface where the Earth's axis of rotation intersects the surface. It is known for its extreme cold temperatures and is covered by ice year-round. The North Pole is considered the northernmost point on the Earth and is not associated with any specific time zone.
3.
In what format would you write the numbers to locate something on the Earth?
Correct Answer
B. Degrees, Minutes, Seconds
Explanation
The correct answer is "Degrees, Minutes, Seconds." This format is commonly used to specify the location of a point on the Earth's surface using latitude and longitude coordinates. The degrees represent the whole units of latitude or longitude, the minutes represent fractions of a degree, and the seconds represent further subdivisions of a minute. This format allows for precise and accurate location identification.

0 degrees longitude starts at an imaginary line running through Greenwich, England. What is the name of this imaginary line?
Correct Answer
A. Prime Meridian
Explanation
The Prime Meridian is the correct answer because it is the imaginary line that runs through Greenwich, England and serves as the starting point for measuring longitude. It divides the Earth into the Eastern and Western Hemispheres and is used as a reference point for determining the longitude of any location on Earth. The Equator is another imaginary line that divides the Earth into the Northern and Southern Hemispheres, while the Arctic Circle and North Pole are not related to longitude measurement.
5.
What is the imaginary line at 180 degrees longitude that separates one day from another called?
Correct Answer
B. International Date Line
Explanation
The International Date Line is the correct answer because it is the imaginary line located at approximately 180 degrees longitude. It serves as the dividing line between one calendar day and the next. When you cross the International Date Line from east to west, you subtract one day, and when you cross from west to east, you add one day. This line helps to maintain a consistent and standardized system of timekeeping across different regions of the world.
6.
Who is closer to the Equator: Freddy, standing at 41 degrees North Latitude, or Suzanne, standing at 12 degrees North Latitude?
Correct Answer
B. Suzanne
Explanation
Suzanne is closer to the Equator than Freddy because her latitude of 12 degrees is closer to 0 degrees (the Equator) compared to Freddy's latitude of 41 degrees. The closer a latitude is to 0 degrees, the closer it is to the Equator.
7.
Who is closer to the Prime Meridian: Mike, standing at 72 degrees, 30 minutes East Longitude, or Shirley, standing at 72 degrees, 30 minutes West Longitude?
Correct Answer
C. They are the same distance.
Explanation
Since the Prime Meridian is 0 degrees Longitude, both Mike and Shirley are the same number of degrees and minutes from that line - just in opposite directions!
8.
What are the latitude and longitude lines?
Correct Answer
A. Imaginary lines that divide the Earth
Explanation
Latitude and longitude lines are imaginary lines that divide the Earth. These lines are used to determine specific locations on the Earth's surface. Latitude lines run horizontally and measure the distance north or south of the Equator, while longitude lines run vertically and measure the distance east or west of the Prime Meridian. Together, these lines create a grid system that helps in accurately identifying and locating any point on the Earth.
9.
What does the equator, an imaginary line, divide the Earth into?
Correct Answer
A. Northern and Southern HemispHeres
Explanation
The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres. It is located at 0 degrees latitude and circles the Earth horizontally. The equator is significant because it is equidistant from the North and South Poles, making it the point of reference for latitude lines. This division affects climate, day length, and seasonal variations, with regions near the equator experiencing tropical climates.
10.
What is the main line of longitude called?
Correct Answer
C. Prime meridian
Explanation
The prime meridian is the line of longitude that passes through Greenwich, England. It is considered the mainline of longitude because it serves as a reference point for measuring all other longitudes. By convention, the prime meridian has a longitude of 0 degrees, and all other longitudes are measured east or west of it. This line helps establish standard time zones and is used as a reference for navigation and mapping purposes.
