Question:Question 1When rounded to the nearest day, the Sun takes approximately____ days to drift around the entire sky, while the Moon takes approximately___ days.Question 2Match the appropriate moon phase to the description given.The phase between waxing gibbous and waning gibbous. [ Choose ] full moon new moon first quarter last quarter The phase between waxing crescent and waxing gibbous. [ Choose ] full moon new moon first quarter last quarter The phase between waning gibbous and waning crescent. [ Choose ] full moon new moon first quarter last quarter The phase between waning crescent and waxing crescent. [ Choose ] full moon new moon first quarter last quarter Question 3Tonight is a full moon. Three nights from now, the moon’s phase will be [ Select ] [“waning gibbous”, “waning crescent”, “waxing gibbous”, “waxing crescent”] . Roughly a week from now, the moon’s phase will be [ Select ] [“last quarter”, “first quarter”] . Ten nights from now, the moon’s phase will be [ Select ] [“waning crescent”, “waxing gibbous”, “waxing crescent”, “waning crescent”] .Question 4Why does the Moon’s appearance change over the course of its cycle of phases?Question 5 eclipses occur when the Moon’s shadow falls upon the Earth, which can happen during the moon phase. On the other hand, eclipses occur when the Earth’s shadow falls upon the Moon, which can occur during the moon phase.Question 6Why don’t eclipses occur dozens of times over the course of a year?Question 7Which of these are planets that are visible to the naked eye from Earth’s surface?the MoonMarsUranusMercuryPlutoJupiterSaturnNeptuneVenusQuestion 8Typically, the planets drift ward through the night sky from night to night, much like the Moon. However, they occasionally exhibit motion in which they appear to drift ward.Question 9The ptolemaic model of the universe is a centric model with the at its center.The model supported by Copernicus and Kepler is a centric model with the at its center.Question 10Kepler’s first law states that the shape of the orbits of the planets is , with the Sun at one .Kepler’s second law states that, if a line is drawn between a planet and the Sun, equal are swept out in equal times. In other words, planets move when closer to the Sun.c. Kepler’s third law states that the square of a planet’s orbital is proportional to the cube of the planet’s average orbital .Question 11Planets [ Select ] [“rotate”, “revolve”] around the Sun and [ Select ] [“rotate”, “revolve”] on their axis.Question 12The terrestrial planets (Mercury, Venus, Earth, and Mars) and jovian planets (Jupiter, Saturn, Uranus, and Neptune) are very different. For the following characteristics, match whether it describes the terrestrial planets or the jovian planets.orbit close to the Sun [ Choose ] terrestrial planets jovian planets orbit far from the Sun [ Choose ] terrestrial planets jovian planets predominately rocky [ Choose ] terrestrial planets jovian planets predominately gaseous [ Choose ] terrestrial planets jovian planets high density [ Choose ] terrestrial planets jovian planets low density [ Choose ] terrestrial planets jovian planets few, if any, moons [ Choose ] terrestrial planets jovian planets many moons [ Choose ] terrestrial planets jovian planets faster rotation [ Choose ] terrestrial planets jovian planets slower rotation [ Choose ] terrestrial planets jovian planets Question 13Why is Venus hotter than Mercury, even though Venus is about twice as far out from the Sun as Mercury is?Question 14Which of these planets or dwarf planets have no moons?NeptunePlutoUranusVenusMarsJupiterMercurySaturnQuestion 15What is Saturn’s rings composed of? How could we be sure of this just from observations on Earth?Question 16What are dwarf planets? Why is Pluto now considered a dwarf planet?Question 17Of the major moons of the solar system:a. appears to have an ocean beneath its cracked icy crust.b. has an atmosphere of methane.c. has the most volcanic activity of any object in the solar system.Question 18 are the rocky remains of the early solar system, primarily found in a belt between and .Question 19 are the icy remains of the early solar system, primarily located in the belt and the cloud.Question 20Fragments from asteroid collisions or debris from comets make up [ Select ] [“meteors”, “meteorites”, “meteoroids”] . When one of these enters Earth’s atmosphere and burns up, the resulting streak of light is called a [ Select ] [“meteorite”, “meteoroid”, “meteor”] . If part of it manages to survive and reach the Earth’s surface, the remains are called a [ Select ] [“meteorite”, “meteoroid”, “meteor”] .Question 21The “surface” of the Sun is called the , and it has a temperature of K.Question 22The most abundant element in the Sun is , while the second most abundant is .Question 23 are patches on the Sun’s surface that appear dark due to being than the rest of the Sun’s surface. Their number rise and fall in a regular cycle that lasts an average of years.Question 24The aurora in the northern hemisphere is caused by the stream of protons, electrons, and other ions from the Sun known as the . These charged particles excite molecules in the air, which then radiate in different wavelengths of light.Question 25How is energy produced in the core of the Sun (and other stars as well)? Be as specific as possible.
