Opening where magma is forced up and flows out onto Earth's surface as lava forming a volcano.
Steep walled depression around a volcano's vent
Result of an unusually hot area at the boundary between Earth's mantel and core that forms volcanos when melted rock is forced upward and breaks through the crust
An opening in Earth that erupts gases, ash, and lava
Broad, gently slopping volcano formed by quiet eruptions of basaltic lava
Bits of rock or solidified lava dropped from the air during an explosive volcanic eruption
Cinder Cone Volcano
Steep-sided, loosely packed volcano formed when tephra falls to the ground
Volcano built by altering explosive and quiet eruptions that produce layers of tephra and lava
largest intrusive igneous rock body that forms when magma being forced upward towards Earth's crust cools slowly and solidifies underground
Solid igneous core of a volcano left behind after the softer cone has been eroded.
Igneous rock feature formed when magma is squeezed into a vertical crack that cuts across rock layers and hardens underground
Large circular-shaped opening formed when the top of a volcano collapses
Igneous rock feature formed when magma is squeezed into a horizontal crack between layers of rock and hardens underground
