A new Terrestrial planet has been discovered orbiting a
nearby Sun-like star. Astronomers have obtained spectra
of this planet and determined that the atmosphere is
composed of roughly 99% CO2, and the remaining 1% is
mostly N2 and is very thin compared to Earth's
atmosphere. Briefly describe how the planet could have
developed such an atmosphere.
If liquid water is rare on the surface of planets, then most Terrestrial planets must have CO₂-rich atmospheres. Why?

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…arrow_forwardWhat are the conditions necessary for a terrestrial planet to have a strong magnetic field?

- We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals. a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ? b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a.
