The Earth rotates at a slow and constant speed of about 1670 kilometers per hour at the equator. This speed is not fast enough to be felt by the human body. Additionally, our bodies have adapted to the Earth's rotation over time, making it seem like we are standing still.
Our sense of motion is relative. We only feel motion when there is something to compare it to. Since we are constantly moving with the Earth, we do not feel its rotation. It's similar to being on a moving plane - you don't feel like you're moving because you're moving at the same speed as the plane.
No, we cannot feel the Earth's rotation during an earthquake. Earthquakes are caused by sudden movements in the Earth's crust, which are separate from the Earth's rotation. The effects of an earthquake, such as shaking and vibrations, are felt because they are happening directly beneath us.
The Earth's rotation does have an impact on the atmosphere and oceans, but these effects are not directly felt by our bodies. Wind is created by differences in temperature and air pressure, while ocean currents are caused by a combination of factors including the Earth's rotation, wind, and differences in water temperature.
The Earth's rotation can be felt in space by astronauts, but it is not a noticeable sensation. In space, there is no air or resistance to create friction, so there is no force to make us feel the Earth's rotation. Astronauts can only feel the effects of the Earth's rotation when they are moving relative to something else, such as when they are on a spacecraft or performing a spacewalk.
