A cutaway that shows the way up

A volcano is a vent in the Earth's crust that lets lava, ash and gases escape from a magma chamber below. The Inside a volcano sheet draws that path in red: the chamber at the bottom, the conduit up the middle and the crater at the top.

Eight sheets, 4 or 5 crayons

Four sheets color all 144 squares: Erupting volcano, Inside a volcano, Volcano at night and Ash cloud over a volcano. Brown is in 7 easy keys; the Volcano at night is drawn in black instead.

The easy Ash cloud over a volcano has only 2 red squares: the crater under the cloud.
On the Sleeping volcano with a snow cap 15 squares stay white: the snow.

Questions and answers

Which color by number volcano shows the inside?

Inside a volcano. It is cut in half, so the magma chamber and the conduit that rises from it can be colored. Open More options and pick it under Pictures; the detailed grid adds gray and black layers of rock.

Is there a volcano that is not erupting?

Yes, two: the Sleeping volcano with a snow cap and the Crater lake. Neither has lava, so neither needs the red crayon; the other six sheets all do.

How many crayons does the erupting volcano need?

Five, numbered 1 to 5: blue for the sky, yellow for the sparks and the heart of the fountain, red for the lava, brown for the mountain and orange inside the fountain. All five are in a basic box of 8.

How this list was compiled: Our own pixel pictures, drawn square by square for this site on 12 by 12 and 24 by 24 grids in October 2026. Nothing is traced, scanned or copied from clip art, and no picture shows a brand, a logo or a character from a film, show, book or game. The facts in the guide and in the Inside a volcano, Ash cloud over a volcano and Crater lake descriptions were checked against the Wikipedia articles Volcano, Volcanic crater, Magma chamber, Lava, Volcanic ash and Volcanic crater lake in October 2026. The color and square counts were counted from the finished grids. Licence: own work
