Earth

OLogy Series
place

The Earth is our home. So far, it's the only place that we know of that has life. Everywhere you look on Earth there is life. This is possible because Earth has lots of water. It's also just the right distance from the Sun. Some people call Earth the "Goldilocks planet." It's not too hot (like Venus), and not too cold (like Mars), it's just right!

Oceans on Earth help control:

population

earthquakes

temperature

Are you right?

Correct!

Most of our planet is covered by ocean. In fact, oceans cover over 75 percent of the Earth's surface. Oceans help spread warmth from hot to cold climates.

A lunar eclipse happens when:

Earth gets in between the Moon and the Sun

a dark storm cloud passes in front of the Moon

the Sun stops shining for one hour

Are you right?

Correct!

During a lunar eclipse, Earth gets between the Moon and the Sun. When this happens, the Earth casts a shadow on the Moon. A lunar eclipse only happens when the Moon is full.

Rosamond Kinzler, earth scientist

Most of Earth's volcanoes are underwater where nobody can see them! A chain of volcanoes nearly 70,000 kilometers (43,500 miles) long circles through the Earth's oceans like seams in a baseball.

The Earth's surface is dynamic, which means that it is a really great place to live.

The Earth is dynamic. It is always changing. The Earth's plates are always on the move. In fact, the Earth under your feet is moving almost as fast as your fingernails grow!
