Why earth is unique from the other planets in the solar system and why is it important to protect and preserve its resources?

Earth is one special planet. It has liquid water plate tectonics and an atmosphere that shelters it from the worst of the sun’s rays.

Why is the atmosphere so important?

The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation keeping the planet warm through insulation and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.

Why does the Earth have atmosphere?

Our atmosphere protects the Earth from the harsh rays of the sun and reduces temperature extremes acting like a duvet wrapped around the planet. … Mars and Venus have atmospheres but they cannot support life (or at least not Earth-like life) because they don’t have enough oxygen.

How is our atmosphere different from the?

Answer : Earth’s atmosphere is different from Venus and Mars in the composition of air. Earth’s atmosphere is composed of various gases like oxygen carbon dioxide nitrogen water vapour along with various gases in small quantities.

Why is Venus atmosphere so different from Earth’s?

Venus received a lower abundance of water-rich componds and a higher fraction of sulfer-rich compounds than the earth. … Earth’s chemistry was different and it was farther out from the sun so that even larger bodies of liquid water could be present and that made all the difference in the world.

What is the main difference between Venus and Earth?

Venus has an atmosphere that is about 100 times thicker than Earth’s and has surface temperatures that are extremely hot. Venus does not have life or water oceans like Earth does. Venus also rotates backwards compared to Earth and the other planets.

What do the atmospheres of Venus and Mars teach us about our own atmosphere?

The atmospheres of our two neighbours Venus and Mars can teach us a lot about the past and future scenarios for our own planet. … Intimately linked to the story of water – and ultimately to the big question of whether life could have arisen beyond Earth – is the state of a planet’s atmosphere.

How are Mars and Earth similar and different?

Mars is only about one-half the diameter of Earth but both planets have roughly the same amount of dry land surface area. … Mars and Earth are very different planets when it comes to temperature size and atmosphere but geologic processes on the two planets are surprisingly similar.

Why doesn’t Mars have an atmosphere?

Earth’s magnetic field protects us from high-energy particles coming from the Sun by deflecting them away from the planet avoiding our atmosphere from being stripped away. Mars doesn’t have a magnetic field of its own so solar radiation strikes its atmosphere directly knocking atoms off into space.

How are the atmospheres of the inner planets different from the atmospheres of the gas giants?

The terrestrial planets are rich in heavier gases and gaseous compounds such as carbon dioxide nitrogen oxygen ozone and argon. In contrast the gas giant atmospheres are composed mostly of hydrogen and helium. The atmospheres of at least the inner planets has evolved since they formed.

What best describes the atmosphere of Mars?

The atmosphere of Mars is about 100 times thinner than Earth’s and it is 95 percent carbon dioxide. Here’s a breakdown of its composition according to a NASA fact sheet: … Carbon monoxide: 0.08 percent. Also minor amounts of: water nitrogen oxide neon hydrogen-deuterium-oxygen krypton and xenon.

Why is atmospheric pressure so much lower on Mars compared to Earth?

The atmosphere of Mars is much thinner than Earth’s. The average surface pressure is only about 610 pascals (0.088 psi) which is less than 1% of the Earth’s value. … Owing to the larger distance from the Sun Mars receives less solar energy and has a lower effective temperature which is about 210 K (−63 °C −82 °F).

Why is Mars red quizlet?
