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.
longitude lines latitude lines
encircle the earth

are part of a grid mapping system

run east and west

are also known as parallels

are all the same length

Explanation:

To solve this, we analyze each row by referring to the passage:

1. Encircle the Earth

From the passage: "Latitude and longitude are imaginary lines that encircle the Earth." So both longitude and latitude lines encircle the Earth.

2. Are part of a grid mapping system

From the passage: "The two are part of a grid mapping system." So both are part of the grid mapping system.

3. Run east and west

From the passage: "Lines of longitude run north and south, while lines of latitude run east and west." So latitude lines run east - west, longitude lines do not.

4. Are also known as parallels

From the passage: "Latitude lines are also known as parallels". So only latitude lines are known as parallels.

5. Are all the same length

From the passage: "Although lines of latitude can be different lengths, lines of longitude are all the same length." So only longitude lines are all the same length.

Filling the table (checking the appropriate boxes):

	Longitude lines	Latitude lines
Are part of a grid mapping system	$\boldsymbol{\checkmark}$	$\boldsymbol{\checkmark}$
Run east and west		$\boldsymbol{\checkmark}$
Are also known as parallels		$\boldsymbol{\checkmark}$
Are all the same length	$\boldsymbol{\checkmark}$

(If the task was to fill the checkboxes, the above table shows the correct markings. If you needed a different format, please clarify the specific question like "Which lines run east and west?" etc.)
