These are 10 Amazing Nature Phenomena

10. Ice Circles

An ice disc, ice circle, or ice pan is a natural phenomenon that occurs in slow moving water in cold climates. Ice circles are thin and circular slabs of ice that rotate slowly in the water. It is believed that they form in eddy currents. Ice discs have most frequently been observed in Scandinavia and North America, but they are occasionally recorded as far south as England and Wales. 

9. Red Tides

Red tide is a common name for a phenomenon known as an algal bloom (large concentrations of aquatic microorganisms) when it is caused by a few species of dinoflagellates and the bloom takes on a red or brown color. Red tides are events in which estuarine, marine, or fresh water algae accumulate rapidly in the water column, resulting in coloration of the surface water. It is usually found in coastal areas.

These algae, known as phytoplankton, are single-celled protists, plant-like organisms that can form dense, visible patches near the water's surface. Certain species of phytoplankton, dinoflagellates, contain photosynthetic pigments that vary in color from green to brown to red.

8. Columnar Basalt

During the cooling of a thick lava flow, contractional joints or fractures form. If a flow cools relatively rapidly, significant contraction forces build up. While a flow can shrink in the vertical dimension without fracturing, it can't easily accommodate shrinking in the horizontal direction unless cracks form; the extensive fracture network that develops results in the formation of columns. The topology of the lateral shapes of these columns can broadly be classed as a random cellular network. These structures are predominantly hexagonal in cross-section, but polygons with three to twelve or more sides can be observed. The size of the columns depends loosely on the rate of cooling; very rapid cooling may result in very small (<1 cm diameter) columns, while slow cooling is more likely to produce large columns.

7. Sun Dogs

A sun dog or sundog, also called a mock sun or a phantom sun, is an atmospheric phenomenon that creates bright spots of light in the sky, often on a luminous ring or halo on either side of the sun.

Sundogs may appear as a colored patch of light to the left or right of the sun, 22° distant and at the same distance above the horizon as the sun, and in ice halos. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Sundogs are best seen and are most conspicuous when the sun is low.

6. Moeraki Boulders

The Moeraki Boulders are unusually large and spherical boulders lying along a stretch of Koekohe Beach on the wave cut Otago coast of New Zealand between Moeraki and Hampden. They occur scattered either as isolated or clusters of boulders within a stretch of beach where they have been protected in a scientific reserve. The erosion by wave action of mudstone, comprising local bedrock and landslides, frequently exposes embedded isolated boulders. These boulders are grey-colored septarian concretions, which have been exhumed from the mudstone enclosing them and concentrated on the beach by coastal erosion.

5. Penitentes

Penitentes, or nieves penitentes (Spanish for "penitente-shaped snows"), 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.

4. Light Pillars

A light pillar is a visual phenomenon created by the reflection of light from ice crystals with near horizontal parallel planar surfaces. The light can come from the Sun (usually at or low to the horizon) in which case the phenomenon is called a sun pillar or solar pillar. It can also come from the Moon or from terrestrial sources such as streetlights.

3. Catatumbo lightning

The Catatumbo Lightning is an atmospheric phenomenon in Venezuela. It occurs only over the mouth of the Catatumbo River where it empties into Lake Maracaibo. The frequent, powerful flashes of lightning over this relatively small area are considered to be the world's largest single generator of tropospheric ozone, that is, ozone that does not replenish the stratospheric ozone layer.

It originates from a mass of storm clouds at a height of more than 5 km during 140 to 160 nights a year, 10 hours per day and up to 280 times per hour. It occurs over and around Lake Maracaibo, typically over the bog area formed where the Catatumbo River flows into the lake.

After appearing continually for centuries, the lightning ceased from January to April 2010, apparently due to drought. This raised fears that it might have been extinguished permanently. The phenomenon reappeared after several months.

2. Cave of the Crystals

Cave of the Crystals or Giant Crystal Cave  is a cave connected to the Naica Mine 300 metres (980 ft) below the surface in Naica, Chihuahua, Mexico. The main chamber contains giant selenite crystals (gypsum, CaSO4·2 H2O), some of the largest natural crystals ever found. The cave's largest crystal found to date is 12 m (39 ft) in length, 4 m (13 ft) in diameter and 55 tons in weight. The cave is extremely hot with air temperatures reaching up to 58 °C (136 °F) with 90 to 99 percent humidity. The cave is relatively unexplored due to these factors. Without proper protection people can only endure approximately ten minutes of exposure at a time.

1. Pink and White Terraces

The Pink Terraces, or Otukapuarangi ("fountain of the clouded sky") in Māori, and the White Terraces, also known as Te Tarata ("the tattooed rock"), were natural wonders of New Zealand. They were thought to have been completely destroyed by the 1886 eruption of Mount Tarawera, being replaced by the Waimangu Volcanic Rift Valley.

The Terraces were formed by geothermally heated water containing large amounts of silicic acid and sodium chloride from two large geysers. These geysers were part of a group of 40 geysers in the nearby area.

The Pink and the White Terraces were 800 metres apart. The White Terraces were at the north end of Lake Rotomahana and faced away from the lake at the entrance to the Kaiwaka stream. They descended to the lake edge 40 metres below. The extra sunlight they received from facing north gave them a more bleached or white appearance. The Pink Terraces were about two thirds of the way down the lake sheltered from the harsh sun on the western shores, facing south-east. Their pink appearance (near the colour of a rainbow trout) was largely due to less sunlight reaching them and therefore less bleaching.
