Have you ever needed to go to a place but you weren’t sure where it is?
Have you ever wondered why it doesn’t snow in the Philippines?
How did you try to find the answers to your questions?
People use maps and globes to find the location of a place and to look at where it is in relation to other places.
Maps and globes help us understand, for example:
But what is a map? What is a globe? Are they the same? If they aren’t, how are they different from each other? Are there things we can use a map for that we can’t do with a globe?
Let’s find out!
The earth is like a big ball, what we call a sphere.
But it’s so big that the only way we can look at the earth as a whole is if we go to outer space and view the earth from a distance.
A globe is like a small version of the earth. It shows the geography of the world — all the land forms and all the bodies of water in the exact location and distance to each other as they are in the real Earth.
The imaginary line that runs through the middle of the earth is called the equator. It divides the earth into two equal halves: the northern hemisphere and the southern hemisphere. The northernmost point of the earth is called the north pole, while the southernmost point is called the south pole.
Because it is spherical (ball-shaped) the globe is a much more accurate representation of the earth. Unlike in flat maps, the size, shape, distance, and other characteristics of land and water elements do not get distorted.
Globes can only show the big picture — an overall view — of the earth. Smaller places such as individual towns and streets cannot be seen in a globe.
A map is a flat representation of a particular place.
Unlike a globe, which always shows the whole world, a map can show the entire earth or just a very tiny part of it. There are continent maps, country maps, city maps, or even maps of just a single building.
A map, like a globe, can show the geography of a place, or it can be used to show the specific characteristics of places — and how they differ from each other — in things like climate or population or disaster risk.
Strictly speaking, latitude refers to a place’s distance north or south of the equator (the line dividing the earth into northern and southern hemispheres).
However, people also use the term “latitude” to refer to the imaginary lines that go around the earth east-west parallel to the equator. If the earth is drawn with its north pole at the very top and the south pole at the very bottom, the latitudinal lines would be horizontal in position, just like the equator.
Longitude — a place’s distance east or west from the prime meridian — is used to refer to the imaginary lines that connect the north and south poles. The longitudinal lines are perpendicular to the latitudinal lines and are vertical in position when the earth is drawn upright.
Together, the lines of latitude and longitude form a grid that helps us specify the location of a place relative to the equator and the prime meridian.

The most notable imaginary lines in the globe are the following:
The worksheets below are designed to help you master the concept of maps and globes, latitude and longitude, and the “special” imaginary lines of the earth.
The worksheets are arranged from the most basic to the most comprehensive. The first worksheet is very easy: identifying a map and globe based on their definition. The next couple of worksheets are for identifying the lines used in a globe or map. The quiz is for assessing if you remember the most essential parts of the lesson.
