Why is Mars known as the “Red Planet?”
Mars has a chemical called iron oxide (rust) in its soil
that causes the surface to take on a reddish appearance.

This is the second largest and lightest planet in the solar system. It's so light that its density would allow it to float on water.
What is Saturn.

Fusion (the changing of hydrogen into helium) occurs in what part of the sun?
What is the core

What do colors mean as it relates to a star's temperature?
ROYGBV
Red stars are coller than blues stars.
300
A chunk of rock from outer space that burns up in the atmosphere.
What is a meteor.

Why do we have season's?
Seasons are influenced by the tilt of Earth on its' axis. When it tilits toward the sun the Northern hemisphere has summer...when it tilits away, the Northern hemisphere has winter.

What happens to the years of planets as they are further away from the sun?
The further away they are the longer their year because it takes them longer to revolve around the sun.

Name the 3 layers of the Sun's atmosphere.
What is the photosphere, chromospehere and corona.

What is the relationship between stars and galaxies?
Galaxies are made of billions of stars.

What do the terms waxing and waning mean in relation to the moon phases?
When the phases are said to be waxing, the visible
portion of the moon seems to be getting larger. When
they are waning, the visible part seems to be getting
smaller. The moon waxes and wanes from right to left.

Why is Venus considered the hottest planet in the Solar System?
Venus has a tremendous Greenhouse Effect – Due to a large amount of carbon dioxide in the atmosphere (98%) -the CO2 traps the heat and causes the surface temperature to reach around 700 Fahrenheit.
500
What impact does the sun have on our planet Earth? Think about the effect solar flares have as well.
The sun provides heat/light energy but can damage plant and animal life with its ultraviolet rays (UV). The solar flares of the sun can interrupt radio communications but in a positive sense create the Northern and Southern lights.
500
Explain the difference between absolute and apparent magnitude?
Apparent is how bright it looks from its' current location.
Absolute is the brightnes from a standard distance.

Distances within the Solar System can be measured in what unit?
What is astronomical units.
500
Identify three things you know about Solar Eclipses.
1) Only last a few minutes (maximum 8)
2) Occurs when the moon blocks out sunlight from reaching the Earth. Only the corona (outer rim) of the sun is still visible.
3) Only 1-2 occur per year due to the moon's orbital tilt.
4) People in the umbra (dark shadow) see a total eclipse.
500
Describe why Earth and other planets are called 'Goldilocks' planets.
Goldilocks planets have the right atmosphere for survival and are also located just the right distance from their sun so they are not too hot or too cold.
