Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What makes a volcano erupt?When magma rises, the gases inside form bubbles, the pressure builds, and if it gets too high the rock breaks open, letting the magma out.
2. How can volcanoes erupt in so many different ways?The thickness of the magma and how fast the gases escape decide if it will just flow out as lava or explode into ash and bombs.

Exsolution: The process by which dissolved gases separate from a liquid to form bubbles.
Viscosity: A fluid's resistance to flow; high viscosity means thick and slow-moving, low viscosity means thin and fast-moving.
Pyroclastic Flow: A fast-moving current of hot gas and volcanic debris that flows down the side of a volcano.
