|---|---|---|---|---|---|
| show | metals sunk to the centers a long time ago when the interiors were molten throughout
🗑
|
||||
| show | Heat from radioactive decay.
🗑
|
||||
| The reason that small planets tend to lose interior heat faster than larger planets is essentially the same as the reason that _________. | show 🗑
|
||||
| show | not much - on human time scales, the mantle looks like solid rock
🗑
|
||||
| show | Mars's interior has cooled so much its molten core layer no longer undergoes convection.
🗑
|
||||
| Which of the following most likely explains why Venus does not have a global magnetic field like Earth? | show 🗑
|
||||
| show | plate tectonics and widespread erosion
🗑
|
||||
| show | The nitrogen and oxygen in Earth's atmosphere keep the surface pleasantly warm.
🗑
|
||||
| show | Because molecules scatter blue light more effectively than red light.
🗑
|
||||
| Which of the following best describes how the greenhouse effect works? | show 🗑
|
||||
| show | well below the freezing point of water
🗑
|
||||
| show | The maria formed after the heavy bombardment ended.
🗑
|
||||
| Which of the following best describes the geological histories of the Moon and Mercury? | show 🗑
|
||||
| show | The atmosphere is too cold and thin for liquid water today, yet we see evidence that water flowed on the surface in the past.
🗑
|
||||
| show | Mars lost any global magnetic field that it may once have had.
🗑
|
||||
| show | Chemical reactions between surface rock and atmospheric oxygen literally rusted the surface.
🗑
|
||||
| show | Venus has a much stronger greenhouse effect than Earth.
🗑
|
||||
| show | The high surface temperature that has "baked out" all the liquid water from Venus's crust and mantle
🗑
|
||||
| Which of the following best explain what we think happened to outgassed water vapor on Venus? | show 🗑
|
||||
| Which of the following is the underlying reason why Venus has so little wind erosion? | show 🗑
|
||||
| show | Venus has relatively few impact craters and these craters are distributed fairly evenly over the entire planet.
🗑
|
||||
| show | Seafloor crust is younger than continental crust, so it has had less time in which to suffer impacts.
🗑
|
||||
| Why is Earth's continental crust lower in density than seafloor crust? | show 🗑
|
||||
| show | mantle convection and a thin lithosphere
🗑
|
||||
| Why does Earth have so little carbon dioxide in its atmosphere compared to Venus? | show 🗑
|
||||
| Which two factors are critical to the existence of the carbon dioxide (CO2) cycle on Earth? | show 🗑
|
||||
| show | Cooler temperatures lead to slower formation of carbonate minerals in the ocean, so carbon dioxide released by volcanism builds up in the atmosphere and strengthens the greenhouse effect.
🗑
|
||||
| show | The entire Earth will warm up by the same amount.
🗑
|
||||
| The choices below describe four hypothetical planets. Which one would you expect to have the hottest interior? (Assume the planets orbit a star just like the Sun and that they are all the same age as the planets in our solar system.) | show 🗑
|
||||
| What's the fundamental reason that Mars, unlike the Earth, has become virtually geologically dead? | show 🗑
|
||||
| show | Size: same as Venus. Distance from Sun: same as Mars. Rotation rate: once every 25 hours.
🗑
|
||||
| show | Size: same as the Moon. Distance from Sun: same as Mars. Rotation rate: once every 10 days.
🗑
