Question

latitude and longitude are imaginary lines that encircle the earth. the two are part of a grid mapping system. by identifying where a place is in relation to a line of latitude, and then identifying where a place is in relation to a line of longitude, you can precisely pinpoint any location in the entire world with only two numbers. lines of longitude run north and south, while lines of latitude run east and west. latitude lines are also known as parallels, because they run parallel to the equator, whereas longitude lines are sometimes called meridians. one way to think of lines of latitude is to imagine them as circles around the earth, with the largest circle at the equator and progressively smaller ones stacked above and below. meanwhile, lines of longitude all pass through both the north pole and the south pole. although lines of latitude can be different lengths, lines of longitude are all the same length.

Explanation:

• Encircle the Earth: Both longitude and latitude lines are part of the grid mapping system that helps in pinpointing locations on Earth, so they both encircle the Earth.
• Are part of a grid mapping system: As stated in the text, latitude and longitude are part of a grid mapping system.
• Run east and west: The text clearly mentions that lines of latitude run east and west.
• Are also known as parallels: The text says latitude lines are also known as parallels.
• Are all the same length: The text indicates that lines of longitude are all the same length.

Answer:

• Encircle the Earth: Longitude lines (☑), Latitude lines (☑)
• Are part of a grid mapping system: Longitude lines (☑), Latitude lines (☑)
• Run east and west: Longitude lines (☐), Latitude lines (☑)
• Are also known as parallels: Longitude lines (☐), Latitude lines (☑)
• Are all the same length: Longitude lines (☑), Latitude lines (☐)
