A geologist studies clouds and the sky.

If you want to keep something for later, you can preserve it in a safe place.

A geyser is an eruption of lava.

The equator is an imaginary line that runs from the North Pole to the South Pole.

The earth is shaped like a sphere.

The crust is a layer of rock deep inside the earth.

Fossils are pieces of rock that come from the eruption of a geyser.

We know that dinosaurs lived on the earth because of fossilized bones that have been found.

Earth only has two layers: the crust and the core.

A volcano is caused by an eruption of magma making its way to the surface of the earth.

Extinct means a group of animals that no longer exist on Earth.

The inner core a solid metal ball in the center of the earth.

Solid things take the shape of their container.

The mantle the outermost layer of the earth where we live.

Fossils are made from plants and animals that died many years ago.

When it is cold outside, we wear more layers to stay warm.

Some volcanoes can be destructive when their lava and ash pour out onto the land around them.

Scientists that study fossils and rocks teach us about the history of the earth.

All rocks are either igneous, sedimentary, or metamorphic.

Characteristic can mean size, shape, color, and texture.

Pressure happens when the weight of something presses or pushes against something else.

The surface of the earth is deep down inside of the earth.

Heat, pressure, and time cause the inside of the earth to change.

The earth's surface is covered by continents and oceans.

Salt is an important mineral that is used by people.

When something varies, it always stays the same.

Layers of sediments, or pieces of dirt and rock, pressed on top of one another over time make sedimentary rocks.
