- The condensation hypothesis for the formation of the moon suggests that the moon and Earth formed as a double planet from the same cloud within the solar nebula. It predicts a. that the moon and Earth should have nearly the same mass and radius. b. that the surfaces of the moon and Earth should be very similar and show evidence of plate tectonics. c. that the moon and Earth should have identical compositions and densities. d. all of the above. e. a and c.Planetary scientists are excited about the possibility that some of the moons in the outer solar system might have a global subsurface ocean of liquid water. It's uncertain whether or not Jupiter's moon Callisto has a subsurface ocean, but some scientists think it might. Let's imagine that a short distance below the surface, Callisto has a water layer 20,000 meters thick. Callisto has a radius of 2.410x106 meters. Earth has a radius of 6.378x106 meters, and its oceans are equivalent to a layer of water 3000 meters thick all over the surface of the planet. Which of the following is an accurate comparison of the Earth’s amount of liquid water with this estimate of the amount of water Callisto might have? Group of answer choices If this scenario is correct, Earth and Callisto have roughly the same amount of liquid water. If these scientists are right, Callisto has about one-sixth as much liquid water as the Earth does. If these scientists are right, Callisto has about 11 times as…What are the conditions necessary for a terrestrial planet to have a strong magnetic field? A molten metallic core only Fast rotation only A rocky mantel only Both a molten metallic core and fairly fast rotation Both a molten metallic core and a rocky mantle
- 4) Science fiction movies often portray asteroid belts as crowded, dense regions that require spaceships to maneuver quickly to get through them. In this problem, we will calculate the fraction of volume in an asteroid belt that is actually occupied by asteroids. a) If there are 300,000 large asteroids between 2 and 3 AU from the Sun, and each asteroid is assumed to be spherical with a radius of 100 km, determine the total volume occupied by asteroids in this region. Recall that the volume of a sphere is given by the equation V = 4TR³ /3. b) Let's assume the region in which these asteroids orbit is an annulus with an inner radius of 2 AU, an outer radius of 3 AU, and a thickness of 2Ro. Determine the volume of this region. Recall that the area of a circle is given by the equation A = TR². Here are two conversions that you'll need: 1 AU = 1.496 × 108 km and 1 Ro = 6.955 × 105 km. c) What is the ratio of the volume occupied by asteroids to the volume of the asteroid belt (i.e., the…Question: The current and most scientifically accurate theory for the formation of the Moon is: a.) The large impact theory. b.) The capture theory. c.) The fission theory. d.) The twin formation theory.3. Several years ago, NASA conducted the Lunar CRater Observation and Sensing Satellite (LCROSS) mission to look for evidence of water deep in craters near the south pole of the Moon (www.nasa.gov/mission_pages/LCROSS/main/index.html). Preliminary analysis of the LCROSS data has already demonstrated that there are indeed signifcant quantities of water on the Moon-a useful thing to know if we ever decide to build a permanent base on the Moon. The LCROSS spacecraft was launched from Earth aboard at Atlas V rocket on 18 June 2009. It was then sent on its way to the Moon by a Centaur transfer stage rocket. On 9 October 2009, while being observed by the LCROSS spacecraft, the Centaur rocket crashed into a crater at the south pole of the Moon creating a huge plume of Lunar dust. Instruments on the LCROSS spacecraft measured the spectroscopic properties of this dust and radioed this data back to Earth for analysis. Then, 4 minutes after the Centaur rocket impacted the Moon, the LCROSS…
