Are there volcanoes in mercury?
Compared to other rocky planets, Mercury is fairly quiet.
No winds sculpt its surface, no flowing water carves channels, and no volcanoes spew lava.
But according to planetary geologist James Head at Brown University, the planet was very different billions of years ago..
Did the moon have water?
Minute quantities of oxygen and hydrogen trapped inside rocks beneath the surface suggest there was once more water on the moon than there is now. Recent unmanned missions to the moon have discovered a few remnants of water ice trapped in sheltered craters around the poles, but much of the moon’s surface is now dry.
Would we die if there was no moon?
Without the moon, a day on earth would only last six to twelve hours. There could be more than a thousand days in one year! That’s because the Earth’s rotation slows down over time thanks to the gravitational force — or pull of the moon — and without it, days would go by in a blink.
What would happen if we nuked the moon?
The W25 would be carried by a rocket toward the shadowed side of the Moon where it would detonate on impact. The dust cloud resulting from the explosion would be lit by the Sun and therefore visible from Earth.
Who is bigger moon or earth?
The moon is a bit more than one-fourth (27 percent) the size of Earth, a much smaller ratio (1:4) than any other planets and their moons. … Double those figures to get its diameter: 2,159.2 miles (3,475 km), less than a third the width of Earth. The moon’s equatorial circumference is 6,783.5 miles (10,917 km).
What if the moon was bigger?
(And with a smaller moon, we might be less stable than we are.) But a bigger moon probably wouldn’t affect Earth’s stability much, Siegler said. It would make the planet’s tilt harder to change, which would mean a more stable climate, which “just means maybe ice ages wouldn’t happen as often,” he told me.
Is moon volcanically active?
Because the Moon does not show any evidence for recent volcanic or geologic activity, it is sometimes called a “dead” planet. The settings of mare volcanism reveal another major difference from volcanism on the Earth. Specifically, Earth’s volcanoes mostly occur within long linear mountain chains.
Is the Moon a dead planet?
Though volcanic activity on the moon ended about 3 billion years ago, the Apollo missions picked up thousands of earthquakes on the moon, or moonquakes. Moonquakes tell us that the moon is not geologically dead. It’s still acting like a planet today.
Is the Moon still alive?
The NASA mission that plunged a rocket into the moon’s surface last month detected about 25 gallons of water in the form of vapor and ice — enough to inspire hope for a lunar colony. By John Johnson Jr.
Why is the moon not geologically active?
Hints that the moon is not quite geologically dead though have been around since the Apollo era, 50 years ago. Apollo missions 12, 14, 15 and 16 left working “moonquake detectors” (seismometers) on the lunar surface. … It is now widely agreed that these are thrust faults, caused as the moon cools down from its hot birth.
How old is the earth?
4.543 billion yearsEarth/Age
Is moon bigger than Sun?
The Moon is about 400 times smaller than the Sun, but it also just happens to be about 400 times closer. The result is that from Earth, they appear to be the same size. And when its orbit around Earth takes the Moon directly between Earth and the Sun, the Moon blocks our view of the Sun in what we call a solar eclipse.
Does the moon have earthquakes?
A moonquake is the lunar equivalent of an earthquake (i.e., a quake on the Moon). They were first discovered by the Apollo astronauts. The largest moonquakes are much weaker than the largest earthquakes, though their shaking can last for up to an hour, due to fewer attenuating factors to dampen seismic vibrations.
What happens if we lose the moon?
The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
Is gold on the moon?
There is water on the moon … along with a long list of other compounds, including, mercury, gold and silver. That’s according to a more detailed analysis of the chilled lunar soil near the moon’s South Pole, released as six papers by a large team of scientists in the journal, Science Thursday.
Who found water on the moon?
On 24 September 2009, NASA published in the Science journal that its Moon Mineralogy Mapper (M3) instrument, which was also on-board the Chandrayaan orbiter, had detected water on the moon from orbit. Just a day later, ISRO announced that MIP had discovered water three months before M3 did.
What would happen if there is no moon at all?
It is the pull of the Moon’s gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth’s tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
Is the water on the Moon drinkable?
Liquid water cannot persist at the Moon’s surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space. However, scientists have conjectured since the 1960s that water ice could survive in cold, permanently shadowed craters at the Moon’s poles.
