When in the part of its orbit closest to the Sun, Pluto has an atmosphere of nitrogen and methane similar to Triton's, but what happens when it is farther from the Sun ?
- A. These gases are not present
- B. These gases are like plasma
- C. These gases are frozen
- D. These gases are volatile
Explanation
As Pluto moves farther from the Sun, its surface becomes colder and nitrogen and methane condense and freeze onto the surface. This causes much of its temporary atmosphere to collapse.
