Volcanoes

Fourth graders discover that a volcano is a doorway from deep inside the Earth, learning how melted rock rises and erupts, why volcanoes come in different shapes, and how they build new land over time.

QUESTION 1
What is the difference between magma and lava?
Magma is melted rock below the surface; once it reaches the surface and flows out, it is called lava.
QUESTION 2
How does a volcano erupt?
Pressure from magma and gas builds up underground until it bursts out through a vent at the surface.
QUESTION 3
How do volcanoes build new land?
When lava cools and hardens it becomes new rock, and over many eruptions this builds mountains and even islands.

Create: my volcano diagram.

Have students draw a volcano cross-section, label the magma chamber, vent, and crater, and add arrows for the eruption, so the hidden structure makes sense. A printable volcanoes worksheet is in the Science library.
