ASTR 101 Final- Young (PART 5- new material)

Uranus and Neptune

On which of the giant planets do we think we can find deep "oceans" of liquid and ice water, methane and ammonia?

Saturn

On which planet have astronomers witnessed rare violent storms that produce lightning?

the Kuiper Belt

Our modern understanding of Pluto is that it is a member of:

Hydrogen

The Gas Giant planets are composed mostly of ___________.

The temperature and pressure increases as you go down in the planet

Why are the interiors of the giants liquid?

They are made of dark organic material

Why can't we see rings around Uranus even with an optical telescope?

Jupiter's gravities prevented material in that zone from getting together

Why do astronomers today think that we have an asteroid belt and not a planet between Mars and Jupiter?

It rotates very fast

Why is Saturn oblate?

Ice

A main difference between asteroids and comets is that asteroids are mostly made of rock and comets are mostly made of

The wind direction alternates East/West

A planet will have bands in its atmosphere like Jupiter if:

meteorites

Chunks of solid material that survive passing through the Earth's atmosphere and are found on the Earth's surface are called

Asteroid

How was Ceres classified before it was called a dwarf planet?

In the asteroid and Kuiper belt

Some of the early planetesimals that formed the solar system still survive today. Where would you find such planetesimals?

Charged particles from the sun colliding with atoms in the atmosphere

The Auroras are caused by

E. all of the above

The Red Spot of Jupiter is A. a high pressure storm system in the atmosphere B. twice the size of Earth C. variable in shape D. long-lived (observed for over 300 years) E. all of the above

Charged atoms; straight

The ion tail of a comet is made of _________ and is ___________.

Jupiter

The planet that has an axis that points roughly straight up, and thus has no seasons to speak of, is:

Billions of chucks (of various size) that all orbit the equator of each planet

The rings of the giant planets consist of:

Cracks and ridges in the ice surface and few craters

What evidence can you give that shows the surface of Jupiter's moon Europa must be relatively young?

impact craters

What features are abundant on Earth's moon and almost absent on moons like Titan and Io?

An icy nucleus

When a comet is not active far from the Sun, what does it look like?

Have a meteor shower as the dust burns up

When a comet leaves its dusty debris behind in its orbit, the Earth can pass through this debris and

Moons torn party tidal forces

Where did most of the particles in Saturn's rings come from?

Enceladus

Which moon has geysers that eject water and ice into space?

D. Thin atmosphere with large daily temperature changes

Which of the following best describes the surface of Mars? A. Very cold with high pressure B. Dim with thick toxic atmosphere C. Yellow sky and low surface pressure D. Thin atmosphere with large daily temperature changes

Rocky core, liquid metallic hydrogen, gaseous hydrogen

Which of the following most accurately describes the interior of Jupiter, from its center out to its edge?
