Stratus
Stratus clouds are low-level clouds that spread like a horizontal sheet across the sky. They are often seen on overcast days and can bring light precipitation.
Clouds move fast across the sky due to the wind. The wind pushes the clouds along, causing them to travel quickly.
Clouds move across the sky due to the wind. The wind carries the clouds in the direction it is blowing, causing them to drift and change shape as they move.
When clouds are moving fast across the sky, it usually means that there is strong wind at higher altitudes pushing the clouds along.
In Greek mythology, Apollo is not associated with carrying the clouds across the sky. Apollo's chariot is typically linked to carrying the sun across the sky each day. The clouds are usually seen as the domain of other deities, such as Zeus or Iris.
Stratus clouds are often found in lower altitudes and appear as a blanket covering the sky. They are known for their uniform, gray appearance and can produce light rain or drizzle.
Clouds
Clouds move across the sky due to the movement of air in the atmosphere. Wind carries clouds from one place to another, causing them to drift and change shape as they travel.
This is an example of cloud movement caused by wind. Wind carries the clouds along, causing them to move across the sky.
Techinally the kind of cloud that spreads over the the sky in layers is the cumulonimbus cloud, but the cumulonimbus cloud spreads out in THICK layers over the sky. The question would be if the cumulonimbus cloud really does spread over the sky in layers.
Clouds are moved across the sky by the wind. The direction and speed of the wind determine how fast and in which direction the clouds will move. Temperature differences in the atmosphere can also play a role in cloud movement.
The clouds appear to move across the sky because of the Earth's rotation.
