# The Collision-Ring Theory Seems Best To Describe How

## What does the collision ring theory describe?

Answer and Explanation: Collision ring theory is the reigning theory of how our moon developed. Billions of years ago likely before any life on Earth had evolved a planet-sized object collided with the Earth creating a far greater cataclysm than the meteor which would kill of the dinosaurs much later.

## Is it true that the moon is humid airless and has an irregular surface?

## How are the size and the mass of the moon different from the Earth?

Mass density and gravity

The moon’s mass is 7.35 x 1022 kg about 1.2 percent of Earth’s mass. Put another way Earth weighs 81 times more than the moon. The moon’s density is 3.34 grams per cubic centimeter (3.34 g/cm3). … A person who can jump up 10 feet on Earth would be able to jump almost 60 feet on the moon.

## Does the moon have variations in its surface temperature?

Temperatures change all across the moon as both the near and far side experience sunlight every lunar year or terrestrial month due to lunar rotation. The moon tilts on its axis about 1.54 degrees — much less than Earth’s 23.44 degrees. This means the moon does not have seasons like Earth does.

## How do scientists believe the Earth’s Moon was formed quizlet?

How do scientists think the moon was formed? The moon was formed when material from an object Mars-sized and earth’s outer layers were thrown into earth’s orbit and eventually came together to form the moon. … The moon is between the earth and the sun.

## How do astronomers think the moon was formed quizlet?

How do astronomers think the moon was formed? When the Earth was very young a planet sized object collided with it. material from the collision was thrown into orbit around Earth. Eventually the materials combined to form the moon.

## What is the currently accepted best theory for the origin of the Moon?

What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.

## What is true of the Moon’s orbital and rotational periods quizlet?

What is true of the Moon’s orbital and rotational periods? They are equal.

## What is one important way in which both the Moon and Mercury are different from Earth?

After all the two bodies have significant differences: unlike the moon Mercury has a global magnetic field its density is higher there is an abundance of volatile elements such as sulfur its surface contains much less iron particularly in its crustal silicates — which indicates that the processes deep inside both …

## What is the mass of a moon?

Bulk parameters
Moon Earth
Mass (1024 kg) 0.07346 5.9724
Volume (1010 km3) 2.1968 108.321

## Why is mass different on the Moon?

A: Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon. The moon’s gravitation force is determined by the mass and the size of the moon. … This means that if you went to the moon you would weigh less even though your mass stays the same!

## What are some differences between the Earth and the Moon?

The first and major difference between the earth and the moon is that the earth is a planet and moon is a satellite (the earth goes around the sun and the moon goes around the earth which is a planet). Majority of the planets do have satellites orbiting them. The earth has only one satellite.

## Is Mars Hot or cold?

Despite its red hot appearance Mars is very cold. According to the National Weather Service Mars has an average surface temperature of about -81°F. This can go all the way down to -220°F in the winter and up to about 70°F on Mars’ lower latitudes during the summer.

## Did NASA find water on the moon?

In August 2018 NASA confirmed that M3 showed water ice is present on the surface at the Moon poles. Water was confirmed to be on the sunlit surface of the Moon by NASA on October 26 2020.

## Why is moon dust toxic?

Lunar dust has silicate in it a material commonly found on planetary bodies with volcanic activity. Miners on Earth suffer from inflamed and scarred lungs from inhaling silicate. On the Moon the dust is so abrasive that it ate away layers of spacesuit boots and destroyed the vacuum seals of Apollo sample containers.

## What are the maria on the moon quizlet?

Maria are the large smooth dark areas of the Moon’s surface. They have few craters. This is a Latin word for “seas” (think of mare). These regions like most of the Moon are devoid of water.

## How does Pluto’s demotion from a planet to a dwarf planet support the solar nebula theory?

How does Pluto’s demotion from a planet to a dwarf planet support the solar nebula theory? Pluto’s composition and orbit more closely resemble that of a Kuiper belt object and Pluto does not have the characteristics of the outer planets.

## Why does the moon lack an atmosphere quizlet?

Why do mercury and the Moon have almost no atmosphere? A – The gravity at their surfaces is low so most gas molecules travel fast enough to escape the planet.

## How were the maria on the moon created quizlet?

2 – Maria formed when lava flowed out of the moon filled large craters and cooled to solid rock. The composition of the moon and the composition of Earth’s mantle are similar.

## What formed the maria Why are they smooth?

The maria were formed after large impacts from meteors carved out basins in the lunar crust. When the Moon was volcanic magma seeped to the surface filled the basins and eventually hardened resulting in the relatively smooth flat areas seen today.

## How were craters formed?

Craters are formed by the outward explosion of rocks and other materials from a volcano. Calderas are formed by the inward collapse of a volcano’s magma chamber. Craters are usually much smaller features than calderas and calderas are sometimes considered giant craters.

## Which hypothesis best explains the way scientists think the moon was formed?

The prevailing theory supported by the scientific community the giant impact hypothesis suggests that the moon formed when an object smashed into early Earth. Like the other planets Earth formed from the leftover cloud of dust and gas orbiting the young sun.

## Which theory is the most likely cause of the formation of the moon the theory that is the most likely cause of the formation of the Moon is the hypothesis theory?

Giant Impact Hypothesis

The leading theory for the formation is the “Giant Impact Hypothesis“ which posits a Mars-sized planet collided with the early Earth throwing material into orbit which became the moon.

## What is the great impact theory?

A theory that explains the origins of Earth’s moon postulating that an asteroid roughly the size of Mars impacted the Earth during its formation. This impact resulted in rocky surface material being blown outward from the Earth some of which accreted to form the Moon.

## What is the best description of the Earth’s rotation over its entire history quizlet?

What is the best description of the Earth’s rotation over its entire history? It has slowed down very gradually at about . 0015 seconds per century.

## What is true about the orbital and rotational periods of the Moon?

The Moon’s orbital period is 27.322 days. … Because of the effect on the Moon of tidal forces due to the Earth the same side of the moon always faces the Earth. The rotation period and the orbital period of the Moon are the same. Therefore Earth-bound observers can never see the ‘far-side’ of the Moon.

## What is true about the Moon’s orbital and rotational times?

The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still. Scientists call this synchronous rotation.

## What theory of Mercury’s origin can best explain the fact that its core is made of such dense materials?

What theory of Mercury’s origin can best explain the fact that its core is made of such dense materials? the range of wavelengths or frequencies over which electromagnetic radiation extends. Wavelength was shifted upward (frequency decreased). This means that the source and the detector are moving away from each other.

## How do Mercury and the moon visually compare?

Mercury is often compared to the moon because its surface looks similar to the backside of the moon (the main source of erosion for both is meteorite impact). Both have weak magnetic fields but mercury doesn’t have any Maria like the moon does. Also the density of the moon is much less than that of Mercury.

## How are surfaces of Mercury and the moon Similar different Why quizlet?

Why? Similar: Mercury’s surface is heavily cratered much like the lunar highland. Different: Mercury lacks lunar like maria and has intercrater plains and scarps instead.

## Does the moon rotate?

The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth. … Over time it has slowed down because of the effect of Earth’s gravity. Astronomers call this a “tidally locked” state because it will now remain at this speed.

## Is the sun bigger than the Earth?

The sun lies at the heart of the solar system where it is by far the largest object. It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
