Carbon dioxide is more dense than air.
In areas of high pressure the air is being squeezed more by the air above it than it is in areas of lower pressure. So the air will tend to get pushed away from the high pressure area.
It is important for an organism to belong to a lower trophic level because the lower levels receive more energy for their food. Organisms on the higher levels also rely on all the lower levels.
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
Heat is only energy. In areas of low pressure, such as high altitudes, "heat" particles, which are charged electrons, escape more quickly. As more "heat" (electrons) escapes more quickly, things freeze more quickly. As far as I know melting and boiling points are higher, not lower in high altitudes.
At noon in Summer, the Sun is high in the sky, so the shadows are shorter. At noon in Winter, the Sun is low in the sky, so the shadows are longer. A winter sun is more likely to dazzle you, as it is lower in the sky throughout its travel between dawn to dusk.
After Noon, when the Sun is highest in the sky and the shadows are smallest, the Sun continues towards its setting in the West. Since shadows are on the opposite side of an object from the light source, the shadows are then on the East side. As the light source gets lower in the sky, the shadows get longer.
After sunset, shadows appear longer and darker as the light source moves lower in the sky. The angle of the light creates elongated shadows with more defined edges, adding a sense of depth and contrast to the surrounding environment.
In film, expose for bright. Surrounding areas fall off into darker shadows. If they don't quite reach black, use more sensitive film to extend its range or lower your white setting.

The more light that is cast, the greater opportunity for shadows to be created.
no
Cast and form shadows: -Cast shadows are just typical shadows that are created when light is blocked by an object. -Form shadows are the shadows that are on the object and away from the light source. Usually, in painting, cast shadows are used to give an object a more realistic and 3D look to them.
No. For instance oil is more viscous then water but has a lower density
an object has as many shadows as there are light sources generally

Simply because the Sun is lower in the sky.The sun is in the southern hemisphere in the winter and this lower sun makes longer shadows. This is similar to the longer shadows in the afternoon, when the lower sun makes longer shadows.
