Map Scale- Relationship of a feature's size on a map to its's actual size on Earth
Projection- Scientific method of transferring locations on Earth's surface to a flat map
Meridian- a circle of longitude passing through a location on Earth's surface
Longitude- Distance east or west of an imaginary line
Latitude- Measurement north or south of Earth's equator
Parallel- imaginary line parallel to Earth's equator
Prime meridian- zero of longitude
The three main map projections are Mercator, Robinson, and Goode-Homolosine.
Map scale allows you to be as zoomed in or as zoomed out as you want to be in a location without changing the size of the map. Map projection tries to make an accurate representation of Earth even though it's a sphere. Map projections put the spherical Earth onto a 2D flat paper.
