Underline the Imaginary Lines Direction: Complete each statement about imaginary lines, underline the correct answer. 1. (Latitude, Longitude) is an imaginary line that runs through the Earth’s surface from West to East. 2. Equator is the longest parallel that divides the Earth into two hemispheres (Western and Eastern, Northern and Southern). 3. All latitudes are (parallel, perpendicular) to the Equator. 4. Latitudes are measured in (meters, degrees). 5. As we move away from the Equator towards the Poles, the length of the latitude (increases, decreases). 6. Longitudes are used to locate places in (north and south, west and east). 7. A/An (coordinate system, equator) is a network of intersecting latitudes and longitudes. 8. (Prime meridian, Equator) serves as a reference point for measuring the distance east or west, located at zero degree (0°). 9. North pole and South pole both measured (90°, 0°). 10. All longitudes are (parallel, perpendicular) to the Equator.

Textbook-Style Explanation
Imaginary lines on Earth help us locate places and understand our planet’s geography better. These lines are known as latitude and longitude, and together they form a coordinate system used in maps and globes.
Latitude lines run horizontally around the Earth from west to east. The most important line of latitude is the Equator, which is located at 0° and divides the Earth into the Northern and Southern Hemispheres. Lines of latitude are parallel to each other, and they are measured in degrees from 0° at the Equator to 90° at the North and South Poles. As we move toward the poles, the circles of latitude become smaller in size.
Longitude lines, also called meridians, run vertically from the North Pole to the South Pole, crossing the Equator at right angles, or in other words, they are perpendicular to lines of latitude. The Prime Meridian at 0° longitude passes through Greenwich, England, and divides the Earth into the Eastern and Western Hemispheres. Like latitude, longitude is also measured in degrees, but it goes up to 180° east or west.
When latitudes and longitudes intersect, they form a grid system that allows us to pinpoint any location on Earth. For example, a location might be given as 30°N, 90°W, meaning 30 degrees north of the Equator and 90 degrees west of the Prime Meridian.
Understanding these imaginary lines is essential for navigation, geography, time zones, and global communication.
