Volcano Forms New Pacific Island
Angela Antrim

1NORTHERN PACIFIC OCEAN—Scientists have discovered a new, currently unnamed island in the northern Pacific Ocean. The small island is located in an isolated area between Hawaii and the Marshall Islands. Scientists believe that an erupting volcano formed the island. The new land mass measures roughly two square miles and rises nearly ten feet above sea level.

2Islands form when magma inside the earth spills onto the earth’s surface. Once magma hits the planet’s surface, it is called lava. The erupted lava then cools and hardens to form rocks and land. Scientists believe the volcano that created this new island has been erupting under the ocean for hundreds of years. Nevertheless, the lava has only recently risen above the water’s surface to form land. Scientists think the new island will expand as the volcano continues to erupt.

3The theory of plate movement informs scientists’ knowledge of volcanoes. Scientists believe the earth’s crust consists of eight major, as well as dozens of minor, pieces of land called plates. These plates float on a sea of magma that flows under the earth’s surface. The plates’ movements cause continents to shift and mountains to form. They are also responsible for earthquakes and volcanic eruptions.
