Back

The gravitational force of attraction decreases.

Front

What are meteors?

Back

Meteors are small fragments that break from the icy bodies of asteroids or the rocky bodies of comets orbiting the sun and enter Earth’s atmosphere.

Front

What is a moon?

Back

A moon is a natural satellite that orbits a planet.

Front

Do moons orbit the sun?

Back

No, moons orbit planets, not the sun.

Front

How does the distance of the moon from Earth change over time?

Back

The moon moves approximately one inch away from Earth each year.

Front

What effect does the increased distance of the moon have on its orbital motion?

Back

The moon would orbit slower and have a greater orbital path.

Front

What would happen if Earth were too far from the sun?

Back

Biological functions would not be possible as available energy would decrease and water would turn to ice.

Front

What is the role of Earth's atmosphere?

Back

Earth's atmosphere regulates temperature and prevents UV rays and meteorites from reaching the surface.

Front

What could happen if the composition of Earth’s atmosphere were changed?

Back

There may not be enough carbon or oxygen in the atmosphere to support life.
