What is the primary source of erosion?
Erosion by Water Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
Does the moon have weathering and erosion?
However, the surface of the Moon doesn't change like it does on Earth. Because the Moon has no atmosphere and no liquid water, weathering, erosion, and deposition don't take place. Landslides, earthquakes and volcanoes also don't happen on the Moon either.
What is the primary cause of erosion on the moon quizlet?
What is the primary cause of erosion on the Moon? Meteoroid impacts have battered the surface of the Moon for billions of years and are the primary cause of erosion.
Is there erosion on moon?
The Moon has almost no erosion because it has no atmosphere. That means it has no wind, it has no weather, and it certainly has no plants. Almost nothing can remove marks on its surface once they are made.
Is there erosion on Moon?
The Moon has almost no erosion because it has no atmosphere. That means it has no wind, it has no weather, and it certainly has no plants. Almost nothing can remove marks on its surface once they are made.
What is the primary cause of erosion on the Moon quizlet?
What is the primary cause of erosion on the Moon? Meteoroid impacts have battered the surface of the Moon for billions of years and are the primary cause of erosion.
What is the likely source of lunar ice?
Older ice could have been sourced from water-bearing comets and asteroids impacting the surface, or through volcanic activity that drew water from deep within the Moon. But there aren't many big water-bearing impactors around in recent times, and volcanism is thought to have ceased on the Moon over a billion years ago.
What are the major factors that rule out the CO formation theory for the Moon Earth system?
What are the major factors that rule out the co-formation theory for the Moon-Earth system? Each body has a different density and a different chemical composition. The cratering of the lunar highlands shows us: they are older than the smoother maria.
What caused craters on the Moon?
Craters are the most common surface features on many solid planets and moons—Mercury and our Moon are covered with craters. This portion of the Moon is covered by numerous circular holes. These are impact craters, each of which was formed when an asteroid or comet collided with the Moon's surface.
What is the source of the fine powdery dust found on the Moon’s surface?
What is the source of the fine, powdery dust found on the Moon's surface? It is the result of many meteoric impacts, breaking surface rocks into pieces.
Is lunar water drinkable?
You have to take the soil, or ice deposits, and have to process it to get water. You have to purify it so you can drink it. Otherwise, it wouldn't be safe to drink. Lunar regolith (lunar soil) are pretty nasty little particles, and they can cause a lot of respiratory issues.
What is the primary method used to determine how the Moon 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.
What are the four main theories about the formation of the moon?
The four main theories proposed by modern scientists on how the moon was formed include capture theory, fission theory, condensation theory, and giant impact theory.
What caused the surface of the Moon to look the way it does?
The phases occur because the Sun lights different parts of the Moon as the Moon revolves around the Earth. That means the reason we see different phases of the Moon here on Earth is that we only see the parts of the Moon that are being lit up by the Sun.
How are craters on the Moon formed for kids?
Craters are formed when asteroids or comets strike the Moon. Most of the larger craters formed early in the Moon's history, until about 3.9 billion years ago. The Moon and all other planetary bodies in our solar system still are hit by asteroids and comets — they usually are small and infrequent, however.
What is the soil on the Moon made of?
The lunar soil consists of three basic components: (1) rock fragments, (2) mineral grains and (3) glass particles.
Why is there sand on the Moon?
It's formed when meteoroids crash on the moon's surface, heating and pulverizing rocks and dirt, which contain silica and metals such as iron. Since there's no wind or water to smooth rough edges, the tiny grains are sharp and jagged, and cling to nearly everything.
Is Silent Sea real?
It premiered on Netflix on December 24, 2021. The title The Silent Sea comes from the Sea of Tranquility on the moon; the story follows a crewed mission to retrieve samples from a lunar research base. Mostly science fiction, it also blends genres like thriller and mystery.
Is there gold on moon?
Digging a little deeper than the Moon's crust, scientists have discovered that the Moon does indeed have a number of precious metals such as gold and silver.
What is the Moon made of and how did it form?
The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.
How did the Moon form quizlet?
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.
What are the three theories on the origin of the Moon explain them?
This hypothesis was that a molten moon had been spun from Earth because of centrifuge-like forces and became the dominant explanation. There are three theories as to how our planet satellite could have been created: the giant impact hypothesis, the co-formation theory, and the capture theory.
What is the surface of the Moon made of?
The average composition of the lunar surface by weight is roughly 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, 0.42% chromium, 0.18% titanium and 0.12% manganese. Orbiting spacecraft have found traces of water on the lunar surface that may have originated from deep underground.
How are the 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.
How do you make a crater on the moon?

What are 3 main types of landforms found on the Moon?
While the craters, highlands and maria are the moon's three main landforms, the moon's surface has a number of other highly visible features.
What is the source of the dust found on the Moon quizlet?
What is the source of the fine, powdery dust found on the Moon's surface? It is the result of many meteoric impacts, breaking surface rocks into pieces.
Can the Moon burn you?
Moon dust may not burn you, but it's no picnic. Like Earth sand, moon dust is effectively made of tiny glass shards, but the sharp edges have not been worn down by erosion.
What is lunar water Netflix?
A group of astronauts are sent to the moon with a special assignment — to bring back samples of a mysterious substance at all costs. But what they find upon arrival is that their mission is a lot more dangerous than they ever imagined.
What is water ice on Moon?
The Moon has no atmosphere, any substance on the lunar surface is exposed directly to vacuum. For water ice, this means it will rapidly sublime directly into water vapor and escape into space, as the Moon's low gravity cannot hold gas for any appreciable time.
