If the Earth were to be moved to where Venus is today,
A) the oceans would evaporate, blocking light from the Sun and causing global temperatures to fall
B) carbon dioxide would be released from the oceans leading to higher temperatures but liquid water could still exist on the surface
C) the oceans would evaporate slightly producing a slightly warmer, more humid planet
D) the oceans would evaporate and carbonate rocks would decompose producing a runaway greenhouse effect much more severe than the one that exists on Venus today
