Based on what you learned about Venus, select all of the correct statements from the following list.
Because of constant cloud cover, we have no maps of the surface of Venus.
Venus' clouds are made of water that drifted upward, because water is lighter than the carbon dioxide in the atmosphere.
In size and mass, Venus is very similar to Earth.
Venus' atmosphere is much thicker than Earth's, and much hotter.
Due to being closer to the sun and therefore slightly hotter than Earth when it first formed, Venus' water vapor could not condense to form oceans. This lack of carbon dioxide-absorbing liquid water has caused Venus to suffer a runaway greenhouse effect.
Venus is geologically dead.
Venus rotates in the opposite direction as Earth, and therefore has a magnetic field of opposite polarity to Earth's.
