The inner planets

have this in common

Page 3: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is a small rocky surface?

Page 4: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

These are the names of the gas giants.

What are Jupiter, Saturn, Uranus and Neptune?

Page 6: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

The largest and most massive planet

Page 7: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is Jupiter?

Page 8: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

Neptune is very similar in size and color to this

planet.

Page 9: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is Uranus?

Page 10: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

This inner planet once had liquid water on its surface.

Page 11: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is Mars?

Page 12: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

The gas giants can’t let this escape into space because

the planets have very strong gravitational pulls.

Page 13: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is their atmosphere?

Page 14: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

This is the direction Uranus rotates.

Page 15: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is on its side?

Page 16: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

This force tends to pull together the matter in stars.

Page 17: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is gravity?

Page 18: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

This is likely to happen to the universe in the future.

Page 19: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is, it will expand forever?

Page 20: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

A loose grouping of a few thousand stars.

Page 21: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is an open cluster?

Page 22: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

Saturn’s rings are made up mostly of

these types of chunks.

Page 23: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What are chunks of ice and rock?

Page 24: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

This may indicate that a planet may exist near a distant star.

Page 25: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is a wobble or slight forward and backward

motion?

Page 26: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

This supports the hypothesis that Mars may once have had

the conditions needed to support life.

Page 27: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

present?

Page 28: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

The four outer planets have this in common.

Page 29: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is they are larger than Earth and are made mainly of hydrogen and

helium?

Page 30: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

This explains why many large optical telescopes are

located on mountains.

Page 31: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

What is so they can be above the atmosphere?

Page 32: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

A meteoroid that enters Earth’s atmosphere

produces this streak of light.

Page 33: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

Astronomers predicted the existence and orbit of Neptune based on this.

Page 37: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

orbit of Uranus?

Page 38: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

Meteroids usually come from these.

Page 39: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

Page 40: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

One of the conditions required for life on Earth is this liquid.

Page 41: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

For this reason, Europa is considered a good place to

look for life.

Page 43: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.

These are two ways Venus and Earth are much alike.

Page 49: 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 A BCDE.
