The shadow is grey but not complete black as that of opaque object.

At noon, or when the sun is in the middle of the sun is in the middle of the sky. It is directly above you so it casts arely any shadow. One could argue that it is shortest at night, when it is non-existent, but that technically means that there is no shadow to measure.
It is called a solar eclipse. And when the Earth casts a shadow on the moon, it is called a lunar eclipse.

The shadow is not a solid 'black' colour. It can be the same colour as the object and the shadow allows you to see through it more than an opaque objects shadow. An opaque object would block the light but a translucent object would give a shadow that you could quite easily see through
Everything has a shadow. I think maybe because the shadow is cast upon it's self. Every object that stands in light casts a shadow, unless that object is light (produces light). A light bulb illuminated on a sunny day,has no shadow of the illumined parts. A flashlight in the sun light is a waste, a flame from a lighter on a sunny day is almost invisible. If an object casts no shadow, then, that object is light. I like to describe it as, (concerning people) a humble person casts no shadow.
It is due to the angle and position of the torchlight relative to the object casting the shadow. The nearer the torchlight is to the object, the bigger the shadow that the object casts.
From the absence of light. Shadow is form from an opaque or translucent object blocking a light source (since light travels in a straight line).

Any large object, such as a rock or a mountain will cast a shadow on the moon.
An object casts a shadow whenever it is illuminated. It really has nothing to do with the angle. Regardless of the angle, it will cast a shadow. The LENGTH of the shadow it casts, however, is dependent upon the angle at which the light strikes the object. A stop sign will cast a very narrow shadow when the sun is directly overhead, for example, but will cast a very long one at sunrise or sunset.
1.8 meters. The ratio of object to shadow is 10:6. Therefore if the object is 3, the shadow is 1.8 ( 6/10x3).
Earth casts the shadow.
Either the Moon casts its shadow on Earth, or the Earth casts its shadow on the Moon.
