• c) the sun creates most
• d) the sun creates all
• e) both a) and c)

Explain how the sun gives the earth its seasons.

Which of the following is a false statement?

• Mars' atmosphere is extremely thin
• On Saturn, a warm, high stream of gas blows in a loop at its north pole
• Liquid water is essential for life
• Mercury's poisonous atmosphere interacts with its magnetic field to form plasma tornadoes
• Earth is in the "Goldilocks Zone"

List the planets in increasing order of their distance to the Sun

What kind of currents are driven by changs in saltiness and temperature?

• deep water
• surface
• circulating
• warm
• equatorial

What kind of currents circulate water in giant loops on either side of the equator?

• surface
• wind
• cold
• mild
• deep water

Which currents help spread warmth more evenly around the planet?

• deep water
• surface
• circulating
• warm
• equatorial

Which currents can make the weather far to the north or south much milder?

• deep water
• surface
• circulating
• warm
• cold

Which currents can bring cool, moist weather to tropical coasts?

• deep water
• surface
• circulating
• warm
• cold

Which of the following is most true?

• Earth's climate has always changed dramatically, veering between times of tropical heat (even at the poles), and an ice age so cold that ice sheets neared the equator! For 10,000 years, though, Earth's climate has been stable and mild. But recent human activities seem to have raised the temperature by 2.07°F (1.15°C). And that's causing chaos.
• Earth's climate has rarely changed dramatically, veering between times of tropical heat (even at the poles), and an ice age so cold that ice sheets neared the equator! For 10,000 years, though, Earth's climate has been stable and mild. But recent human activities seem to have raised the temperature by 2.07°F (1.15°C). And that's causing chaos.
• Earth's climate has always changed dramatically, veering between times of tropical heat (even at the poles), and an ice age so cold that ice sheets neared the equator! For 10,000 years, though, Earth's climate has been stable and mild. But recent human activities seem to have raised the temperature by 6.07°F (4.15°C). And that's causing chaos.
• Earth's climate has never changed dramatically, veering between times of tropical heat (even at the poles), and an ice age so cold that ice sheets neared the equator! For 40,000 years, though, Earth's climate has been stable and mild. But recent human activities seem to have raised the temperature by 2.07°F (1.15°C). And that's causing chaos.
• Earth's climate has always changed dramatically, alternating between stable and mild, and an ice age so cold that ice sheets neared the equator! For 10,000 years, though, Earth's climate has veering between times of tropical heat (even at the poles),. But recent human activities seem to have raised the temperature by 2.07°F (1.15°C). And that's causing chaos.
