Why is it necessary to have a cast shadow when shading on a drawing?

The cast shadows are generally the darkest parts of any subject, and together with the shadows are often visible when the light surfaces of the objects are invisible. They show the shapes of the objects casting them, and also those of the objects receiving them, and are most important features of any subject.

How will you sketch a sphere?
Start by drawing a circle. A sphere is just a three dimensional circle, so once you have your outline you will need to determine the direction your light is coming from. Having established your light, remember the area furthest away from the light will be in deepest shadow, so shade in that edge. As you move toward the light the shading will need to get lighter. There should be a small area (round in shape) where the high-light is and this should be white or untouched. Finally using the light source, put in a cast shadow to make your sphere look like it is sitting on a surface.
What is the importance of light and shade in drawing?
A plain white page is an example of the white. Take a pencil and draw a line. The only reason you can see the line is because it is different from the white of the page. That is the most simplistic answer possible. But, there is a range of possibilities of tone between pure white and total black - various shades of grey, for instance. Draw a vertical black line representing a wooden post. Such a post would cast a shadow if the sun was shining. The shadow cast would be a grey between the blackness of the post and the whiteness of the page.
How do you draw a diagram of how a shadow is made?
It seems that you are asking about a ray diagram, or ray trace. One of the links below is a picture of a basic ray diagram. It shows how to trace the extent of a shadow cast by an opaque object on a screen. Basically, draw a line from the light source to an edge of the object and continue to where it touches the screen (a point source is easiest, but extended source is more accurate in that it shows where shading is and why). If you draw lines from the light source to several parts of the object, it builds a more accurate picture. This illustrates the phenomenon that light can (hypothetically) project an infinite number of rays (another way to look at it, a wavefront) to cast the exact shape of the object on a background.
How do you draw orthographic projection of curved corners?
All drawing is a form of projection in itself. If you mean how do you project orthographic shapes to trace then the best way would be to place a light 180 degrees behind the object you wanted to draw. This would cast a silhouette (which is essentially what an orthographic drawing is) that you can trace.
When it erupts it can change weather all over the world?
A volcano. Because it can emit enough dust and airborne particles to cast a cooling shadow over the earth for some time.
Why do birds not cast their shadows while flying high in the sky?
Birds flying up in the sky do not cast their shadow because the source of light (sun) is too large compared to the object (bird) and the umbra of the shadow formed on the screen (ground) is very small, negligible.So it is tough to see its shadow on the ground. (P.S. If this is a VNS student reading this for Physics research, then I'm pretty sure you're in my grade and you know who I am)
