A new Terrestrial planet has been discovered orbiting a
nearby Sun-like star. Astronomers have obtained spectra
of this planet and determined that the atmosphere is
composed of roughly 99% CO2, and the remaining 1% is
mostly N2 and is very thin compared to Earth's
atmosphere. Briefly describe how the planet could have
developed such an atmosphere.
The cores of terrestrial planets are mostly metal because:
The entire planets are mostly metal
Metals are denser and so sank to the centres of planets when they were still molten
Metals condensed first in the formation of the Solar System
Radioactivity created metals in the core of planets from the decay of uranium
According to the chart below, how do the gas giants differ from the terrestrial planets?
