Self-study
Scientist: Venus contains a hot molten core, like that of Earth. ████ ████ ██████ █████ ████ █████ ███ ██████ ████ ███ ████ ██████████ ██ ██████ ████ ██████ ████████ ███████ ██████ ████████ ███ ████████ ███████ ████ ████████ ██████ █████████ ███ █████ ███ ███████ ██████ ████████ ███ ████████ ██████ ██ ███ ████████ ██ ████████ ███████
"Surprising" Phenomenon
How does Venus expel the excess heat that its core generates, even though it doesn’t expel that heat through active volcanos or fissures caused by the movement of tectonic plates?
Objective
The correct answer should provide a way for Venus to expel excess heat from its core through means besides active volcanos or fissures caused by the movement of tectonic plates.
3.
Which one of the following, ██ █████ ████ ███ ████ ██ ███████ ███ ████████ ███████████ █████████ ██ ███ ██████████
a
Rock on the ███████ ██ █████ ███████ █████ ██ ████ ██████ ████████████ ████ ████ ████ ██ ██████
The temperature at which Venus’s rocks remain solid doesn’t have a clear relationship to the ability to expel excess heat from the core.
b
The surface of █████ ██ ██████████ █████ ████████ ██████████ ████████ ████ ██ ███████ ████ ██████
This describes a way Venus might expel excess heat. The heat might be expelled through the thin surface into space.
c
The interior of █████ █████████ ███████ ████████████ ██ ███████████ ████ ████ ████ ██ ██████
Varying temperatures doesn’t change the fact that Venus still needs to expel excess heat. This doesn’t provide a theory about how Venus expels such heat.
d
Though Venus lacks ██████ █████████ ███ ██████████████ █████████ ██ ███ ███████ ████████ ████████ ████ ████ ██ ██████
Having surface movement doesn’t clearly relate to expelling excess heat. Does surface movement by itself help expel heat? We don’t know.
e
The atmosphere of █████ ██ █████████████ ██████ ████ ████ ██ ██████
The temperature of the outside atmosphere doesn’t suggest a method that allows Venus to expel heat from its core. The outside air might be hotter, but how did it become hotter? From the core’s heat? How did that heat get expelled? We don’t know.
