Which of the following events/impacts could be expected to affect Earth less than an hour after a solar flare occurs. Select all correct answers A. Radio Burst B. Minor Proton Event C. Geomagnetic Storm D. CIR

Assume that Venus has an isothermal atmosphere with a surface temperature of 750 K. The surface pressure of Venus is 90 times the Earth's surface pressure which is about 1013mb. Also assume that the carbon dioxide dominant atmosphere of Venus is photodissociated and oxygen atoms are produced. These oxygen atoms stop the solar wind at the ionopause distance where the atmospheric pressure of Venus and the dynamic pressure of the solar wind are in balance. Accordingly, calculate the lonopause distance of the planet Venus if the solar wind density is 7 #/cm² and solar wind speed is 410 km/sec.

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.
If the cloud layer of Venus is so thick, how is it possible for any sunlight to reach the surface planet the
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…
