Handleiding

In polar regions, the polar lights can often be

viewed at night. In northern latitudes, they are

called the northern lights, or aurora borealis. In

southern latitudes, they are called the southern

lights, or aurora australis. Auroras are caused

by the sun: The sun is constantly emitting tiny

charged particles in all directions. When these

“solar winds” strike the magnetic field of the

Earth, it creates the colorful polar lights in the

Earth’s atmosphere we call auroras.

There are many islands that are created by

volcanoes. Hawaii’s Kilauea is one of the most

active volcanoes on Earth. An interesting

phenomena is caused by the flow of some of the

lava directly into the ocean, constantly creating

large clouds of vapor over the coast. At night,

the lava shows off its beautiful, multifaceted

glowing colors.

Volcanoes can be found all across the Earth.

Volcanism is especially common along the

edges of continental plates. There are

approximately 1,500 active volcanoes on land

masses around the world. They are created

when hot magma rises up from the Earth’s

interior to the surface. It is impossible to predict

when and how powerfully a volcano will erupt.

It is only possible to perform precise

observations of their activity.

MAGMA OR LAVA?

Magma and lava are both names for

molten rock. If the molten rock is found

beneath the Earth’s surface, it is called

magma. If it emerges to the Earth’s surface

in a volcanic eruption, for example, it is

called lava.
