The medium-sized tides that occur across the entire Earth's surface during the Quarter Moon phases are called what?
neap tides
What is a type of rock formed by cooled magma?
Igneous rock is formed from the solidification of magma as it cools.
Is the planet featured in the film Predators a moon of Jupiter?
Whilst the planet seen in the sky bears a striking resemblance, it is unlikely to be Jupiter for the following reasons: 1) The moon on which the soldiers (etc) are stranded appears to have Earth level gravity so it would have be pretty large. It doesn't necessarily have to be as big as Earth itself but it would probably be bigger than any of the other moons around Jupiter - so if such a moon did exist, we would have discovered it, as we have discovered the others using telescopes and space probes. 2) The planet has a tropical climate which suggests it is close to it's parent star (within the "Goldilocks zone"). Jupiter is the 5th furthest planet from the Sun and so any moons around it will be frozen. Also the sun in the movie is (so far as I can tell - the characters don't comment on it) full sized. Whereas the Sun, as it would appear from Jupiter would be very small in the sky. These are the biggest two clues that it is not Jupiter, but merely a planet that resembles it. Now it is possible that the Predator aliens have "cloaked" the planet and are heating it by artificial means... but I think this unlikely. Maybe the sequel will tell us, if there ever is one.
How did the earth's moon became the moon?
Some four billion years ago a massive body, roughly the size of Mars, struck the nascent earth. The debris from this collision settled into orbit around the earth, like a ring. Within just a few thousand years it had coalesced into the moon.
How small can a planet be before it is classified as a dwarf?
The definition of "planet" doesn't specifically list a minimum size. The term is instead defined dynamically: in order to be considered a planet, the body must have "cleared the neighborhood of its orbit". Roughly speaking, this means anything approximately the same distance from the Sun as the potential planet must be either much, much smaller or a satellite (or both) of the planet.For example: There are several thousand known asteroids that come near or cross Earth's orbit. However, they have a much lower mass than the Earth; even if you lumped them all together into a single body, they'd still have a much lower mass than the Earth. So Earth has "cleared its neighborhood" and is a planet.Ceres is the largest known asteroid; large enough for its own mass to have pulled it into an approximately spherical shape (this is another criterion that planets have to meet). It also has a lot of asteroids that are near or cross its orbit, and it's the largest of them ... but it's not nearly as dominant as Earth is; Ceres only represents a bit over a third of the total mass of the asteroid belt (the next largest asteroid is about a third of Ceres' mass). Ceres therefore has not cleared its neighborhood and is not a planet (it's a dwarf planet, because it does have that approximately spherical shape, which is technically called "hydrostatic equilibrium").How about Pluto? It turns out that Pluto's orbit crosses that of Neptune (not literally; there's no possibility they could collide). So it's nowhere near even being the largest thing in its neighborhood, and therefore not a planet (despite being considerably larger than Ceres).The smallest object in the Solar System that's definitely a planet is Mercury, which has a radius of almost 2500 km. The largest (known) object in the solar system that's definitely not a planet (and also not a moon) is either Eris or Pluto; we're not quite sure which because they're both very close to 1160 km radius. So somewhere between the two might be a rough answer. (It turns out that it's easier to clear your orbit if your orbit is closer to the Sun; a Mercury-sized body out beyond Neptune probably wouldn't make the cut.)
Was the moon formed after a planet-sized object collided with the sun.?
No. The moon formed after a planet-sized object collided with Earth.
What was the solar system like when the moon formed?
Scientists theorize that a planet-sized object collided with earth to form the moon.
What do most scientists believe is the origin of the moons?
Scientist theorize that a planet-sized object collided with earth and the moon formed
How was the moon really formed?
The moon formed when a Mars-sized planet collided with Earth when the solar system was still forming, ejecting a portion of Earth into orbit. That rocky debris came together to form the moon.
What came first the sun moon or earth?
Sun first, then the earth and moon formed at the same time around 4.65ga (billions of years ago) when a large moon-sized planet collided with the proto-earth/moon system.
What theory states that the moon formed when a planet sized object collided with earth?
There are four main hypothesis for the formation of the moon. ; Fission hypothesis - The Moon broke off from the Earth ; Capture hypothesis - The Moon was captured ; Co-formation hypothesis - The Moon and Earth were created at the same time ; Giant Impact hypothesis - The Moon was created when a Mars sized object (Theia) crashed into the Earth.
Explain the various stages in the formation of the moon?
The moon formed early in Earth's history when a planet-sized object struck Earth. The resulting debris formed the moon.
How did terestrial planets get moons?
Earth's moon is believed to have formed when Earth collided with a Mars-sized planetoid soon after it formed. Debris from the collision formed a ring around Earth and coalesced into the moon. Scientists still disagree about the origins of Mars' moons Phobos and Deimos. The most prevalent hypothesis is that they are captured asteroids.
Explain the impact theory?
the impact theory states that the moon is formed billions of years ago from condensing gas and debris was thrown off when earth collided with a mars sized object
Why do scientists believe that earth's rocks and the Moon's rocks are similar?
It is believed that the moon was created by a collision between proto-Earth and a Mars-sized planet. The moon was formed from accreted Earth collision material.
Why does uranus rotate on it upside down?
Scientist aren't sure yet but they have a theory that a huge comet or asteroid collided with the blue planet causing it to spin on its side.
How is the moon so big?
Present theories suggest that the moon was formed when proto-earth and another mars sized body collided. The splatter from the impact coalesced into the moon (which was much closer in to the earth at this point. Since then the moon has mooved farther form the earth as it has slowed the earths rate of spin.
