Which of the terrestrial planets have the most similar atmospheric compositions quizlet?
Which of the terrestrial planets have the most similar atmospheric compositions? Earth is the only planet that has active plate tectonics and surface water; Venus has the densest atmosphere and the highest average temperature; and Mercury is the planet with the thinnest atmosphere and the smallest size.
Which terrestrial planet is about one third the size of the Earth?
Mercury. Mercury is the smallest terrestrial planet in the solar system, about a third the size of Earth. It has a thin atmosphere, which causes it to swing between burning and freezing temperatures. Mercury is also a dense planet, composed mostly of iron and nickel with an iron core.
