The higher the dewpoint is, the more moisture that is in the air. The higher the dewpoint is above 65 F, the stickier it will feel outside (feels like you have to breathe in a bunch of moisture with each breath). 75 F or above dewpoint, the air really feels sticky and humid. RH can be more difficult to explain.
Unlike all of the other planets in the Solar System, Mercury is just bare rock. It does have a tenuous atmosphere, but ground and space-based observations see just the gray rocky color of Mercury. This gray color comes from Mercuryâs molten surface that cooled and hardened billions of years ago after the formation of the [â¦]
It is because Mercury s color and the surface are very similar to the Moon. They both are rocky gray and have broken up craters. However, there are some differences between them. The moon, unlike Mercury, has lot of darker areas, or what astronomers call seas.It is because the Moon has a lot of lava flows that creates those dark areas. Also, the Moon has more variety of colors compared to Mercury.he moon, unlike Mercury, has lot of darker areas, or what astronomers call seas.
