This is a physical phenomenon.
Troposphere
The phenomenon responsible for the formation of the highest mountains is Tectonism. This is caused mostly as a result the collision movements of various lithospheric plates. The process of formation of the mountains is termed Orogeny.
snow
The flow of this liquid is a physical phenomenon; but the formation of this "syrup" is a chemical change.
refraction
This is a physical phenomenon.
GRAVITY
Regelation is the phenomenon of melting under pressure and freezing again when the pressure is reduced.Skating is possible on snow due to the formation of water below the skates.Water is formed due to the increase of pressure and it acts as a lubricant.
Troposphere
All geese like to fly in the V formation also known as a skein formation. This formation helps with their flying efficiency and how far they can fly.
The formation you are describing is icicles. Icicles are created when snow on a roof melts due to warmer temperatures, then refreezes as it drips off the edge of the roof, creating long, pointed ice formations.
The amount of water vapor in the air has the greatest effect on the formation of rain or snow. When the air is saturated with water vapor and condensation occurs, precipitation can form as rain or snow depending on temperature conditions.

The formation of ozone and its depletion is a natural phenomenon but at the same time the various man made factors such as the CFC's, the gases released from the jet planes are increasing the rate of depletion which was earlier in equilibrium with the rate of formation of ozone. Thus it can be said that humans are the ones most responsible for it.
A red tide is a natural phenomenon that causes fish to die. The formation of lightning is a phenomenon still not completely understood.
