Volcanic ash can cause engine failure. Landforms are the natural shapes or features of the land.. There are many different types of landforms found on Earth.. What are Landforms?. Mountain. A mountain is a place on Earth’s surface that is much higher than the land around it.. Mr.McMahon . Learning Objectives . To understand . WHY. volcanic activity occurs.. To understand .

Volcano is open passageway from the interior of the Earth that allows blast rock and gases from the interior to the cortex surface in the form of lava. This activity creates mountains.
