D: Both B and C are probable. The problem is right in the core of the planet. Which statement about Mars’ two moons is FALSE? Both B and C are probable. Rank these magnetic fields, from weakest to strongest. 1 decade ago. Mars' magnetic field is so weak because: A: it spins much slower than Earth does. How many moons does Mars have? Most striking style of star's gown wasn't the color, Oscars may have launched a brand-new power couple, Expert on the 'golden egg' of retirement savings, How a Supreme Court case shaped modern policing, Study throws cold water on indoor distancing rule, NYC attacker kicked Chinese American man in the head, 3-time NCAA champion coach leaves for a new job. Whether those planets have managed to retain their atmospheres like Earth or have lost them to space like Mars could have a major impact on how common life is in the universe. Possibly residual activity from a “recent” massive impact. Credit: NASA Like Earth, Mars global magnetic field is believed to have been the result of a dynamo effect caused by action in its core. By comparison, the atmosphere surrounding Mars is less than 1% as dense as Earth’s atmosphere because it lacks magnetic protection. Yahoo Answers is shutting down on May 4th, 2021 (Eastern Time) and the Yahoo Answers website is now in read-only mode. B) its core contains less iron than our own. As expected, a strong magnetic field that could easily withstand the pressure of the solar wind was able to guard its atmospheric ions. Well, it’s time to turn out the lights and say goodbye on astronomy and space? Now Sakata et al. Source:
it core may no longer be molten. Mars Dried Out Because Its Magnetic Field Is So Weak – Earth Changes Media Mars Dried Out Because Its Magnetic Field Is So Weak 0 We finally have an understanding of how Mars transformed from a once habitable, Earth-like planet into the dry world we see today.
Mars once had oceans, but its magnetic field just wasn't strong enough to keep the atmosphere - and most of the water - from blowing away. so why is nasa saying there helicopter flew when it cant in a vaccum? E: All of the above are correct. Their composition is significantly different from Mars … Five years of data from the mission have led to a new map of Mars’ weak magnetic field.

Mars once had a strong magnetic field—like Earth does now—produced by a dynamo effect from its interior heat. 27 January 2021, News

Solar winds carry the thin, weak atmosphere away because Mars has a weak gravitational and magnetic field. Mars' magnetic field is so weak because: - its core contains less iron than our own. Get your answers by asking now. The close encounter between comet Siding Spring and Mars flooded the planet with an invisible tide of charged particles from the comet's coma. Mars has a lower density than the Earth, which implies less iron. James. a) it spins much slower than Earth does. That analysis has influenced theories of how Mars cooled after its formation … Mars had a magnetic field when it was young and its iron core was molten and convecting — which … At the Hermean equator, the relative strength of the magnetic field is around 300 nT, which is weaker than that of Jupiter's moon Ganymede. But new research suggests Mars’s weak magnetic field may have helped its atmosphere escape. Mars is best viewed from Earth when it is at: opposition. magnetic field was to determine if Mars had a global field of internal origin. Mercury’s field is weak because it rotates so slowly. The Earth's center, made from iron and assorted different aspects (yet specially iron) rotates and generates a magnetic field. (Both B and C are probable.) its core contains less iron than our own. Before I speculate on creating a magnetic field around Mars, let me just say that Mars actually does have an extremely weak magnetic field (~40 times weaker than Earth’s) but only in the southern hemisphere. So consequently, Mars has a lot less of a magnetic field because its center is way less energetic. Can we send astronauts to the sun if we go at night? So why Earth has what Mars does not ? Weak Fields, Thin Air. Mars’ magnetic field is so weak because. I like the super moon theory. C: its core contains less iron than our own. Hey Savvy, how about u read your assignments and do your own damn homework? If you read enough about Mars, you’ll realize that Mars once had everything that Earth has now, It’s like Earth being a spoiled sibling, has stripped Mars off of its belongings. The Atlantic Multidecadal Oscillation and its relation to rainfall and river flows in the continental U.S. The reason for Mars weak magnetic field is due to the lack of a large lunar moon for a satellite. The data implied that Mars had a weak magnetic field back then. Mars has a lower density than the Earth, which implies less iron. Mars’s magnetic field was active in its youth, pushing back against the solar wind pressure created by charged particles streaming from the Sun. This occurs when a liquid outer core revolves around a … In late December 2014, NASA's MAVEN spacecraft detected evidence of widespread auroras in Mars's Northern Hemisphere and descended to approximately 20–30° North latitude of Mars's equator. 22 April 2021, News
NASA finds Mars’ magnetic field is 10 times stronger than expected Scientists hope to use this new information to unravel the internal structure and geological history of Mars. On Earth, the flow of liquid iron around a hotter solid core conducts electricity that helps keep the magnetic field in place. So the chef's "magnetic field," as it were, extends to the living room, but not to the second floor of the house. Should SpaceX and Elon Musk save Yahoo Answers now. Mars' magnetic field is so weak because: a) it spins much slower than Earth does. That is a magnetic field, but it is important to get the idea of a magnet straight. 27 January 2021, News

Planetary magnetic fields are formed by the interaction between the convection of interior conducting material (molten rock and metal) and the planet’s own rotation. Both are in retrograde orbits. an alien helicopter was recorded near the mars rover, what more proof do people need that we are not alone? ... Mars Dried Out Because Its Magnetic Field Is So Weak. Four and a half billion years ago, Mars boasted a thick atmosphere and abundant surface water—conditions that could have hosted life.
