Word List
MAGMA
Molten rock found beneath Earth's surface. When magma erupts from a volcano, it is called lava. Magma is generated in Earth's mantle and lower crust.
LAVA
Magma that has reached Earth's surface through a volcanic eruption. Lava can flow slowly for miles or be ejected explosively into the air.
ERUPTION
The sudden release of lava, gas, ash, and rock from a volcano. Eruptions range from gentle lava flows to violent explosions that can alter climate.
CALDERA
A large depression formed when a volcano collapses into itself after a massive eruption. Calderas can be miles wide and are often filled with lakes.
CRATER
A bowl-shaped depression at the top or side of a volcano, formed by an eruption or collapse. The crater sits above the volcanic vent.
PUMICE
A very light, porous volcanic rock formed when lava cools quickly while full of gas bubbles. Pumice is so light it can float on water.
BASALT
A dark, fine-grained volcanic rock that forms from rapidly cooled lava. Most of the ocean floor and many volcanic islands are made of basalt.
PLUME
A column of ash, gas, and rock fragments ejected from a volcano during an eruption. Large volcanic plumes can reach the stratosphere and affect global temperatures.
DORMANT
A volcano that is not currently erupting but is expected to erupt again in the future. Dormant volcanoes can remain quiet for thousands of years before becoming active.
VENT
An opening in the Earth's surface through which volcanic material escapes. Vents can be located at a volcano's summit or on its sides.
About Volcanoes
Volcanoes are openings in Earth's crust where molten rock, ash, and gases escape from below the surface. They form at tectonic plate boundaries and hotspots, and they play a major role in shaping Earth's landscape and atmosphere.
Volcanoes Vocabulary
This puzzle includes terms for volcanic materials like MAGMA, LAVA, and PUMICE, structural features like CALDERA, CRATER, and VENT, and eruption concepts like PLUME and DORMANT. Together they cover the full anatomy of a volcano.
How to Use This Word Search in Class
Pair this word search with a cross-section diagram of a volcano. As students find each word, they can label it on the diagram. For a hands-on extension, build a model volcano and identify the vocabulary terms at each stage of the eruption.
