Water erosion is usually what people think of, but ice, wind and gravity can also cause erosion.
Water erosion is usually along rivers. As the water moves quickly by it rubs on the rock and dirt, causing rivers to slowly get wider.
Ice erosion is caused by glaciers. Sometimes it's a glacier rubbing against land, and there's a lake that was made by a glacier making it's way onto land and then melting.
Wind erosion is a big problem in fields and large open plains with loose dirt. The wind just blows all the dirt away.
Gravity can cause erosion and cliffs. Sometimes along a mountain or cliff the rock won't be able to hold itself up anymore, and gravity will pull it down.
Your answer would be all of them. Wind, water, ice, and gravity.
The main responsible for the delay among the atrial and
ventricular contractions is the action potential conduction velocity of the AV
node cells. If the atria and ventricles contract simultaneously, atria cannot
give any help in filling the ventricles, which is needed, especially in those
with stiff ventricles as in the elderly. Hence atria have to contract first and
then the ventricles.
the answer D. Giant impact hypothesis or large impact hypothesis
The origin of the Moon refers to several explanations regarding the formation process of the Moon, Earth's natural satellite. Theory The large collision hypothesis is the best-known theory regarding the origin of the moon.
<h2>Further explanation
</h2>
The big collision hypothesis theory states that the Moon was formed from debris left over from a collision between Earth and an object the size of the planet Mars, about 4.5 billion years ago. The object that crashed into the Earth is often called Theia taken from the Greek Titan myth, which is the mother of Selene, the goddess of the Moon.
Other hypotheses about the origin of the moon:
- Catching Hypothesis. This hypothesis says that the Moon is an object captured by the Earth.
- Cleavage Hypothesis. This hypothesis says, in the old days, the Earth was spinning very quickly throwing some of its mass.
- Accretion Hypothesis. This hypothesis says that the Earth and the Moon formed at the same time as a double system of ancient accretion disks in the Solar System.
- The Georeactor Explosion Hypothesis. Another more radical hypothesis was published in 2010, saying that the Moon might have been created by a georeactor explosion located along the boundary of the mantle's core in the rapidly rotating equatorial plane of the Earth. This hypothesis can explain the similarity of the composition of the Earth and the Moon.

One of them is smaller, because the moon is much closer to earth than the sun.
Think of the moon orbiting the earth as a smaller version of the earth orbiting the sun.
