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 is the formation mechanism?Generated from a large-scale submarine volcanic eruption, primarily composed of buoyant pumice
2. How does Lakagigar float and move across the ocean?The island is made of pumice, a light volcanic glass that traps gas and becomes buoyant. When enough pumice builds up, it forms a raft that can float. Ocean currents push the raft, making it drift across the sea.
3. Why does Lakagigar have plants and animals on it?The first plants that grow on Lakagigar are hardy grasses and lichens that can survive on rough, porous rock. These plants create tiny homes for insects and give food for birds. The island’s movement can carry these plants and animals to new places.

Pumice raft: A large floating mass of pumice stone formed after a volcanic eruption, capable of transporting organisms.
Island biogeography: The scientific study of the factors that affect the species diversity on islands.
Ocean currents: Continuous, directed movement of seawater generated by forces such as wind, the Coriolis effect, and temperature differences.
