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.
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.
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 are the 3 types of erosion?
The main forms of erosion are: surface erosion. fluvial erosion. mass-movement erosion.
How does gravity cause erosion?
Gravity is responsible for erosion by flowing water and glaciers. That's because gravity pulls water and ice downhill. These are ways gravity causes erosion indirectly. But gravity also causes erosion directly.
What is formed on the Moon’s surface?
The surface of the moon The moon's surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer. Early scientists thought the dark stretches of the moon might be oceans, and so named such features mare, which is Latin for "seas" (maria when there are more than one).
What causes 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.
Which true about weathering in the Moon?
Given that weather is created by the interactions among air, water and sunlight, the moon has no weather. So the moon technically has no weathering.
What is the most common type of erosion?
Rill erosion Rill erosion: The most common type of soil erosion, and frequent during heavy rain. It takes place through several narrow channels called streamlets.
What are 4 examples of erosion?
Some erosion examples include wind erosion, water erosion, glacial erosion, temperature erosion, and mass wasting (such as landslides).

What caused the Moon to 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.
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.
What is the formed on the Moon’s surface?
The surface of the moon The moon's surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer. Early scientists thought the dark stretches of the moon might be oceans, and so named such features mare, which is Latin for "seas" (maria when there are more than one).
What cause the crater to form?
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.
Is weathering possible on moon?
Given that weather is created by the interactions among air, water and sunlight, the moon has no weather. So the moon technically has no weathering.
What are the 3 main types of erosion?
The main forms of erosion are: surface erosion. fluvial erosion. mass-movement erosion.
What are the 3 main types of erosion and describe them?
Erosion involved three processes: detachment (from the ground), transportation (via water or wind), and deposition.
What are the two main causes of erosion?
Four Causes of Soil Erosion
- Water. Water is the most common cause of soil erosion. …
- Wind. Wind can also make soil erode by displacing it. …
- Ice. We don't get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water. …
- Gravity. Gravity is a primary culprit behind the three other causes.

What causes gravity erosion?
Mass movement is an erosional process that moves rocks and sediments downslope due to the force of gravity. The material is transported from higher elevations to lower elevations where other transporting agents like streams or glaciers can pick it up and move to even lower elevations.
Where does gravity erosion occur?

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.
When was the formation of the Moon?
It smashed into the developing Earth 4.5 billion years ago. This collision produced enough heat to create magma oceans and ejected a lot of debris into orbit around the Earth, which subsequently coalesced into the Moon.
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.
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.
How are moon craters formed?
These craters formed when rocks or comets from space smashed into the surface of the Moon. The impact was so powerful that it pulverized the ground – creating what we call regolith – and sprayed it out to form those ejecta rays. You can make craters like those on the Moon using simple baking ingredients!
What’s the weather on the Moon?
When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C). There are also no seasons on the Moon. We have seasons because the Earth tilts on an axis at roughly 23.5 degrees.
