  • Smooth plains that resemble Lunar maria.
  • Intercrater plains, which are pocked with small craters and occupy about 70% of the surface that we have examined.
  • Rugged highlands that bear some resemblance to the corresponding regions on the Moon.

Does Mercury have landforms?

The surface of Mercury has landforms that indicate its crust may have contracted. They are long, sinuous cliffs called lobate scarps. These scarps appear to be the surface expression of thrust faults, where the crust is broken along an inclined plane and pushed upward.

Does Mercury have mountains?

This indicates that the surface of Mercury has dorsa(ridges), highlands, montes(mountains), planitiae(plains), rupes(escarpments), and valles(valleys).

Does Mercury have water on it?

But you might be surprised to know that astronomers have discovered water on Mercury. Not liquid water, but deposits of water ice at the planet’s poles. This is because there are craters at the north and south poles of Mercury which are eternally in shadow.

Does Mercury have oxygen?

Rough Surface – Mercury is a rocky planet, also known as a terrestrial planet. Mercury has a solid, cratered surface, much like the Earth’s moon. Can’t Breathe It – Mercury’s thin atmosphere, or exosphere, is composed mostly of oxygen (O2), sodium (Na), hydrogen (H2), helium (He), and potassium (K).

Does ice exist on Mercury?

Mercury is not alone in having ice on its surface, as water ice has also been discovered on the moon and on small worlds such as asteroids and comets. These locations may have variations in water deposition, however.



What does it rain on Mercury?

Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain! But the surface of Mercury can reach 427 degrees during the day (because it is so close to the Sun) and can drop to -187 at night (because there is no atmosphere to trap the daytime heat).

Is Mercury the hottest planet?

Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus, thanks to its dense atmosphere. But Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

What color is Mercury?

slate gray

The planets of the solar system are varied in their appearance. Mercury is slate gray while Venus is pearly white, Earth a vibrant blue, and Mars a dusky red.

Is Mercury the smallest planet?

How many rings does Mercury have? Zero.

What is Mercury made of?

Mercury is a rocky planet with a huge iron core which makes up a large part of its interior. The core takes up nearly 3/4 of the planet’s diameter. Mercury’s iron core is about the size of the moon.



How would you describe Mercury?

It has a solid surface that is covered with craters. It has no atmosphere, and it doesn’t have any moons. Mercury likes to keep things simple. This small planet spins around slowly compared to Earth, so one day lasts a long time.

What are the most common elements on Mercury?

The atmosphere of Mercury is a “surface-bound exosphere, essentially a vacuum.” It contains 42% oxygen, 29% sodium, 22% hydrogen, 6% helium, 0.5% potassium, with possible trace amounts of argon, carbon dioxide, water, nitrogen, xenon, krypton and neon, according to NASA.

What does Mercury look like in nature?

Elemental mercury is a shiny, silver-white metal that is a liquid at room temperature and is traditionally used in thermometers and some electrical switches. If not enclosed, at room temperature some of the metallic mercury will evaporate and form mercury vapours. Mercury vapours are colourless and odourless.

What happens when mercury touches gold?

Freddie Mercury may have had the golden voice, but real mercury, that endlessly entertaining and dangerous liquid metal, has the golden touch. That is, if it touches gold it will immediately break the lattice bonds of the precious metal and form an alloy in a process known as amalgamation.

Is mercury poisonous to touch?

Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
