10) Earth Science & Astronomy Working Together (6pts)
Now that you have learned more about the Planets in our Solar System, I would like you to take a moment to think about the specific ways in which our knowledge of Earth Science has aided scientists in learning about the Planets in our Solar System.
Describe, in detail, specific ways in which the topics we have covered in Earth Science are used to understand the Planets in our Solar System. Make sure to give 2 specific examples of how Earth Science topics are used to understand the Planets in our Solar System.

1. ______ are found both on Mars and Earth.
|Heavily cratered landscapes preserved from early in the planets’ histories|
|Erosional features related to flowing water|
|Oceans full of water|
|Answer 1 and 2: erosional features related to flowing water AND active tectonic plates|
|Extremely active tectonic plates|
1. The Great Red Spot on the planet Jupiter is
|a type of storm in Jupiter’s atmosphere that can last for a few months at a time before disappearing.|
|a large, long-lived, high-pressure storm in Jupiter’s atmosphere.|
|clouds of dust-laden gas upwelling above the top of a massive mountain or a volcano on the planet’s surface.|
|the colored polar cap of Jupiter.|
1. Many people get confused by the difference between asteroids, comets, meteors and meteorites. In this jumbled sentence choose the correct term describing these astronomical objects: (sorry for the long runon sentence)
are made of water-ice and frozen crystals of methane, ammonia, carbon and originate in the outer reaches of the Solar System, where as Term 2 are composed mainly of rock and rubble, but if either of these (or pieces) enter the Earth’s atmosphere we call it a Term 3, or a shooting star and if they strike the surface of the Earth they are called a Term 4
1. Match the Planet name with its corresponding description and the “earth sphere” the planet is LACKING!
|A.This planet is heavily cratered and is very small in diameter. It has extreme daytime and nighttime temperatures. It is very close to the Sun.The main “Earth Spheres” missing on this planet are: Biosphere, Hydrosphere, & AtmosphereB.This is a Jovian planet with a lot of atmospheric storms! This planet often displays aurora and has a strong magnetic field. It is the largest of the gas giants.The main “Earth Spheres” missing on this planet are: Biosphere and Geosphere.C.A terrestrial Planet with contains seasons similar to Earth, due to it’s axial tilt! The seasons on this planet are longer than on Earth. This planet contains remnant of Huge volcanoes and has polar ice caps. The main “Earth Spheres” missing on this planet are: Biosphere.D.This planet is Blue/Green in color and is a gas giant! It is covered in a thick atmosphere, often riddled with storms that look like white ovals. This Planet has an axis of rotation that is similar to Earth’s, rotating relatively perpendicular to the orbital plane of motion around the Sun.The main “Earth Spheres” missing on this planet are: Biosphere & Geosphere.|
1. Which planet in our solar system has the lowest average density?
1. The atmosphere of Venus mainly consists of the gas molecule ____________, causing the planet to experience a runaway greenhouse effect resulting in the surface being hotter than the surface of Mercury! Earth does not want to become Venus, so we are trying to cut back from producing these greenhouse gases.
1. Why do we experience Seasons on Earth? And
Why is it warmer in the Summer and colder in the Winter in the Northern hemisphere?
|We experience Seasons on Earth due to the 45 degree tilt of the Earth’s rotational axis. The Earth is tilted toward to the Sun in summer and away from the Sun in winter. This allows for the length of day to vary, shorter daylight hours in the summer and longer daylight hours in the winter. The second factor making summers warmer is that when the Earth is tilted away from the Sun, the surface of the Earth receives more direct solar radiation, making it warmer.|
|We experience Seasons on Earth due to the 23.5 degree tilt of the Earth’s rotational axis and the fact that the earth gets closer and further from the Sun throughout the year. This allows for the length of day to vary, longer daylight hours in the summer and shorter daylight hours in the winter, which is one factor causing summers to be warmer than winters. The second factor making summers warmer is that the Earth is physically at lot closer to the Sun in the summer (Northern Hemisphere), making it warmer. In the winter the Earth is much further from the Sun so the Earth is cooler.|

In the winter we receive more indirect solar radiation, which heats Earth’s surface less.|
1. According to the condensation model of the solar system:
|A.||Rocks and iron condense furthest from the Sun|
|B.||Rocks and iron don’t last in the Solar System formation|
|C.||Ices and gases condense condense furthest from the Sun because that is where they originated|
|D.||Ices and gases condense condense furthest from the Sun because they evaporate close to the Sun|
1. Our solar system seems to have formed about how long ago?
|5 billion years|
|5 million years|
|13.5 billion years|
1. Match the moons of Jupiter with their correct description
|A.Surface contains two terrains, one densly cratered and the other linear groves perhaps formed from recent tectonic activity. This would indicate a convecting, metallic core.B.Moon is old as indicated by its heavily cratered surface. Furthest moon from Jupiter.C.Moon has active volcanoes and its interior is most likely warmed by tidal effects from Jupiter gravitationally tugging on the moon. Most active volcanic body in the Solar System!D.Moon has an interior of rock and a surface of frozen water. Subterranean oceans are most likely warmed by tidal effects from Jupiter gravitationally tugging on the moon.|
1. Mars has polar ice caps composed of Carbon Dioxide and Water ice.
1. Which one of the terrestrial planets has a surface landscape similar to that of the older areas of the Moon?
1. Ozone is concentrated in which layer of the atmosphere? ____________.
1. The most probable theory for the solar system’s formation is
|gas and dust clouds condensed to form the Sun, while planets formed later within a nebular disk.|
|an encounter, in which a passing star ripped off material from the Sun to form the planets.|
|condensation of a slowly contracting nebula of hot gas, first into planets in the outer region, then into the Sun at the center.|
|a capture theory in which the Sun captured objects moving through space which then became the planets.|
1. Which of the following statements is true about the equinoxes?
|They occur in June and December|
|Days and nights are equal in length everywhere|
|The Sun’s vertical rays are striking either the Tropic of Cancer or the Tropic of Capricorn|
|The length of daylight at the Arctic and Antarctic Circles is 24 hours|
1. In our solar system, which of the following planets is not a member of the terrestrial group?
1. By what means do most scientists believe the water that fills our large oceans came to reside on Earth? In other words, where did all the water contained in oceans originate from?
|10% from Polar Ice caps on Mars, 10% from green algae, and 80% from water contained in rocks|
|90% from comets, meteoroids, and asteroids, 10% from volatiles and outgassing|
|10% from comets, meteoroids, and asteroids, 90% from volatiles and outgassing|
|80% from green algae and 20% from volatiles and outgassing|
