Most Amazing Natural Phenomena

A natural phenomenon is a non-artificial event in the physical sense, and therefore not produced by humans, although it may affect humans (e.g. bacteria, aging, natural disasters, death). Common examples of natural phenomena include volcanic eruptions, weather, and decay. Most natural phenomena, such as rain, are relatively harmless so far as humans are concerned.

Various types of natural phenomena include (but are not limited to) meteorological phenomena (like hurricanes, thunderstorms, and tornadoes) and geological phenomena (like volcanic activity and earthquakes).

And some of them are just amazing.

Northern Lights

 

Northern Lights is a common name for the Aurora Borealis (Polar Aurorae) in the Northern Hemisphere. Auroras result from emissions of photons in the Earth's upper atmosphere, above 80 km (50 miles), from ionized nitrogen atoms regaining an electron, and oxygen and nitrogen atoms returning from an excited state to ground state. They are ionized or excited by the collision of solar wind and magnetospheric particles being funneled down and accelerated along the Earth's magnetic field lines; excitation energy is lost by the emission of a photon of light, or by collision with another atom or molecule

Mammatus Clouds

Mammatus, also known as mammatocumulus is a meteorological term applied to a cellular pattern of pouches hanging underneath the base of a cloud. The name mammatus, derived from the Latin mamma (meaning “udder” or “breast”), refers to a resemblance between the characteristic shape of these clouds and the breast of a woman.

Red Tides

Red tide is a common name for a phenomenon more correctly known as an algal bloom (large concentrations of microorganisms), an event in which estuarine, marine, or fresh water algae accumulate rapidly in the water column and results in discoloration of the surface water. It is usually found in coastal areas.

Los Penitentes

Penitentes, or nieves penitentes, are a snow formation found at high altitudes. They take the form of tall thin blades of hardened snow or ice closely spaced with the blades oriented towards the general direction of the sun. Penitentes can be as tall as a person.

Sailing stones

The sailing stones, also known as sliding rocks and moving rocks, are a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal intervention. They have been recorded and studied in a number of places around Racetrack Playa, Death Valley, where the number and length of travel grooves are notable. The force behind their movement is not understood and is the subject of research.
