A volcano is a vent in the Earth's surface that spews lava or rocks. When a volcano erupts, magma from the magma chamber flows up a conduit inside the throat of the volcano. Once the magma reaches the surface of the Earth, it is called lava. Volcanoes often look like mountains, in that they have a conical shape, but usually have a crater at the top that distinguishes them.

Draw an inverted V. Erase the point on the V and replace it with a flat, horizontal line. This is the body of the volcano.
Draw a giant, puffy cloud shape over the volcano. This is the top of the smoke spewing from the volcano.
Draw a straight line connecting the far left side of the cloud to the left side of the top of the volcano. Draw a straight line connecting the far right side of the cloud to the right side of the top of the volcano. This shows that the smoke is spewing from the top of the volcano.
Draw several squiggly lines, starting at the top of the volcano and moving down the body of the volcano. This represents the lava dribbling down the volcano's side.
Draw several irregular shapes -- representing rocks -- in the air around the smoke cloud. These rocks have just flown from the exploding volcano, so draw a line behind each rock showing its trajectory as it flies from the top of the volcano.
Draw a horizontally-oriented oval under the ground beneath the centre of the volcano. This is the magma chamber.
Draw two parallel vertical lines up from the centre of the magma chamber to the top of the volcano. This is the conduit through which magma flows.
Draw several lines inside the mountain that run parallel to the flank of the mountainside, to show the layers of rock and ash inside the volcano.
Tips and warnings
- If you wish to colour the volcano, use crayons, markers or coloured pencils. The volcano should be grey or brown. Make the stripes of lava bright red, and the smoke grey. The rocks should be grey as well.
