Admin What would happen if you were on Mercury?
Its proximity to the Sun means that one side of the planet can reach scorching temperatures that exceed 430 degrees Celsius, but Mercury rotates so slowly that the cooler side can dip below -180 degrees Celsius. If you visited Mercury, you’d either freeze or bake to death, depending on which side you walked on.
Why can’t humans breathe on Mercury?
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).
What is the composition of Mercury Venus Earth and Mars?
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a volatile envelope of gases, ices, and, for the Earth, liquid water.
What is the atmosphere composition of Mercury in percentages?
Nitrogen and oxygen are two gases that make up the majority of Earth’s atmosphere, and they appear in Mercury’s as well. The abundance of nitrogen is 2.7 percent of Mercury’s air, and oxygen accounts for 0.13 percent.
What is the composition of the surface of mercury?
Mercury has a solid, cratered surface, much like the Earth’s moon. Mercury’s thin atmosphere, or exosphere, is composed mostly of oxygen (O2), sodium (Na), hydrogen (H2), helium (He), and potassium (K). Atoms that are blasted off the surface by the solar wind and micrometeoroid impacts create Mercury’s exosphere.
What are 10 Things you need to know about mercury?
10 Need-to-Know Things About Mercury. 1 Small World. Mercury is the smallest planet in our solar system – only slightly larger than Earth’s Moon. 2 Inside Track. 3 Fastest Planet. 4 First Look at Mercury’s Previously Unseen Side. 5 Rough Surface.
How does Mercury’s atmosphere affect its internal temperature?
On other planets, the atmosphere functions as a blanket, helping to redistribute heat somewhat. But on Mercury, the thin atmosphere does nothing to stabilize the incoming solar rays—and because the distance to Mercury from the sun is so small, the day side of the planet feels the heat keenly, while the night side,…
How is mercury deposited in the environment?
This airborne mercury can fall to the ground in raindrops, in dust, or simply due to gravity (known as “air deposition”). The amount of mercury deposited in a given area depends on how much mercury is released from local, regional, national, and international sources. Emissions from Power Plants
