Inside a Volcano

Science · Volcanoes & Earthquakes · conceptual

Understand the inside of a volcano: magma is hot melted rock underground, lava is the same material after it reaches the surface, and volcanoes have a magma chamber, vent, and crater

What mastery looks like

  • Explain that magma is melted rock underground and lava is the same material above ground
  • Label a magma chamber, vent, and crater on a volcano cross-section
  • Describe the path magma takes from underground to the surface during an eruption

Check your understanding

If Inside a Volcano looks at a cross-section diagram of a volcano, can they point to the magma chamber, vent, and crater, and explain the difference between magma underground and lava on the surface?
