No. a shadow cannot have its own shadow, because its not something solid and its not blocking the path of the light.
the shadow of the sundial is just called a shadow
Only "The Shadow" knows what evil lurks in the minds of men. How long your shadow is! The clouds will hide your shadow.
A sun block, I'm not sure a pure guess
The size of a shadow depends on, the angle that the light source is hitting the object and the size of the object. In some cases, the amount of light can also affect the size of a shadow.
shadow zones.
The shadow zone refers to an position that does direct P waves from angular distances of an given earthquake.
Shadow zones are regions on Earth where seismic waves are unable to reach due to the planet's core structure blocking or refracting them. These zones help scientists to understand Earth's interior composition by observing the behavior of seismic waves as they travel through different layers of the planet. Shadow zones can vary in size and shape depending on the type of seismic waves and the properties of the Earth's core.
An area on Earth's surface where no direct seismic waves from a particular earthquake can be detected.
It's the focus
P-waves refract as they travel through Earth so do not rach all other pars of the earth's surface. Also S-waves can't travel through liquids and so can't pass through the earth's outer core which also causes a shadow zone.
As the diameter of the liquid core increases, the size of the shadow zone decreases. This is because the larger diameter allows for more refraction of seismic waves, leading to less complete shadowing of seismic waves at certain distances.
Time Zones?
If you mean time zones. There is one. Russia has 7 time zones.
Earth's polar zones are also called the Earth's Frigid Zones.
There are 4 zones.
