3. match the following words with the appropriate definition: 1. the imaginary line which passes through the north and south poles, upon which the earth rotates once every 24 hours 2. runs through the middle of the earth dividing it into northern and southern hemispheres. 3. spheres, as taught in math classes, are three-dimensional lines, and hemi means "half." therefore, the earth has four different possible sections. 4. this type of imaginary line runs perpendicular to the equator on a map 5. this type of imaginary line runs parallel to the equator on a map a. equator b. prime meridian c. longitude d. hemisphere e. latitude

The correct matches are:

1.The imaginary line which passes through the North and South Poles, upon which the Earth rotates once every 24 hours - b. Prime Meridian;

The Prime Meridian is an imaginary line that divides the earth into East and West Hemisphere, as well as going through the North and South Pole. The Earth rotates once every 24 h upon this line.

2. Runs through the middle of the Earth dividing it into northern and southern hemispheres - a. Equator;

The Equator is an imaginary line that divides the Earth on North and South Hemisphere. It is a horizontal line, right in the middle section of the planet.

3. Spheres, as taught in math classes, are three-dimensional lines, and hemi means "half." Therefore, the Earth has four different possible sections - d. Hemisphere;

The Earth is divided into North and South Hemisphere by the Equator, and West and East Hemisphere by the Prime Meridian.

4. This type of imaginary line runs perpendicular to the Equator on a map - c. Longitude;

The longitude lines run perpendicular to the Equator, or with other words, they cut through it at a 90 degree angle.

5. This type of imaginary line runs parallel to the Equator on a map - e. Latitude;

The latitude lines are imaginary lines that are parallel to the Equator, and they are longer when they are closer to the Equator and shorter when they are closer to the poles.
