Exploring Earth ScienceThe Earth and Moon

Travel along and we will find out where we live in space and what we can see

in space.

Do you know what a solar system is?

Do you know what is in our solar system?

Our solar system is made up of an enormous sun and everything that

travels around it.

The closest planet to the sun.

The beautiful planet.

The planet we live on.

The red planet.

The biggest planet.

The king of rings.

A planet made of gases.

The coldest planet.

Planet

A large ball of rock or gas that moves around

the sun.

We live on one of the nine

planets in our system. Other small bodies

called asteroids and comets can be found in our

system also.

Draw the path of the earth around the sun.

OrbitThe planets move in a path around the sun.

StarsA huge ball of hot gases.

(Sun is the nearest star to earth)

• Sunlight comes from the sun to the Earth. The sunlight that warms our faces right now left the sun over eight minutes ago. The sun warms the Earth.

What causes daytime and

night time on the Earth?

What causes the changing of our

seasons?

The spinning around like a top is called rotation. As it spins only one side faces the sun. Day begins when our part of the world turns to face the sun.

Night falls when our part of the Earth turns away from the sun. The side facing away from the sun has nighttime.

This rotation or spinning of Earth causes day and night. The Earth rotates on its axis. The axis is an

imaginary line through its center. It rotates once every 24 hours causing

day and night.

Every day the Earth travels around the sun. The

Earth and the moon travel

together in an orbit around

the sun once a year.

One revolution around the sun equals 365 days. This revolution causes the

changing of the seasons.

When the Earth moves closer to the sun, summer returns. When the Earth moves farther away from the sun in its

orbit, winter returns.
