Class C
shows up around larger airports as a solid magenta line. They have a layer similar to Class B, but on a smaller scale and typically with only one other shelf. The standard ceiling is 4,000 ft. AGL.
In the example above, begins at the surface and extend up to 5,200 feet MSL.

Class A
Extends from 18,000 feet MSL to 60,000 feet MSL,
this airspace is for aircraft traveling long distances over 18,000 feet MSL
Image: Class A
Class B
airspace is shown with a solid blue line around MAJOR airports in circles radiating outward.
The center circles typically starts at the surface and extends up to the top of the airspace. The standard height is 10,000 ft. MSL. There are usually at least 2 other shelfs of circles.
Image: Class B
Class D
airspace is indicated by dashed blue lines around the airport. airspace is around medium-sized airports and typically has a blue number inside of a blue box.
In the example above, the blue number in the box is 30, meaning the airspace ceiling extends up to 3,000 feet MSL.
Image: Class D
Class E
airspace is indicated by a thick, faded magenta line or a dashed magenta line.
Most of the airspace in the United States. airspace typically extends from 1,200 feet AGL to 17, 999 feet MSL (18,000 is the floor of Class A airspace) when there is no overlying airspace.
Image: Class E
Class G
Goes from ground up to 1,200 feet AGL and in some places to 700 ft. AGL (generally up to Class E airspace) - in some areas it doesn't exist at all
This is uncontrolled airspace. airspace does not require any authorizations as long as there are no TSR's or other special restrictions.

Airport Airspaces
Every cubic inch of air over the US is contained in some volume of lettered airspace
The volumes are classified as B, C, D, E, G
Class B, C, and D airports exist in controlled airspace
They are controlled by ATC (Air Traffic Control) and have control towers
Class A is over 18,000 ft., so we don't have to worry about this one
