Question

Which statement is true? Inner and outer planet composition supports the nebular theory because heavier elements condense close to the Sun, and lighter elements condense at cooler temperatures. The big bang is a theory about the origin of the solar system. Nuclear fusion occurs at cooler temperatures, away from the Sun. The inner planets are gas giants, and the outer planets are rocky.

Answer 1

Just had that question, its A. Inner and outer planet composition supports the nebular theory because heavier elements condense close to the sun and lighter elements condense at cooler temperatures.

Answer 2

The true statement among the statements given is " Inner and outer planet composition supports the nebular theory because heavier elements condense close to the Sun, and lighter elements condense at cooler temperatures". This is why terrestrial planets like Earth, Mars, Venus, and Mercury are closest to the sun and are very dense.
