Earth & Space Science
You will learn how to use a globe like a world map.
After completing this tutorial, you will be able to complete the following:
1. How does a globe differ from a map?
~ A globe is a three-dimensional, spherical model of the Earth, while a map is only a flat, two-dimensional illustration of the Earth's surface.
2. Why are globes a more accurate representation of Earth than maps?
~ Globes are a more accurate representation of Earth than maps because they demonstrate Earth's spherical shape. They also present a more precise representation of the relative sizes of Earth's land masses and bodies of water.
3. What are the vertical and horizontal lines on a globe called?
~ The vertical lines on a globe are called lines of longitude, and the horizontal lines are called lines of latitude.
4. What is the prime meridian?
~ The prime meridian is the primary longitudinal line, located at zero degrees. It is the longitudinal version of the equator.
5. How is the distance between the lines on a globe measured?
~ The distance between longitudinal or latitudinal lines is measured in degrees. For example, two longitudinal lines are separated by one degree. Each degree can then be divided into sixty minutes, and each minute can be divided into sixty seconds.
