Waves Oct29

Waves

In fluid dynamics, wind waves or, more precisely, wind-generated waves are surface waves that occur on the free surface of oceans, seas, lakes, rivers, and canals or even on small puddles and ponds. They usually result from the wind blowing over a vast enough stretch of fluid surface. Waves...

Mountains Oct29

Mountains

A mountain is a large landform that stretches above the surrounding land in a limited area usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth by over...

Fractal Mineral Feb10

Fractal Mineral

IGNEOUS rocks formed from lava flows of the Archaean era (>2,700 million years ago) are often found to contain disequilibrium-textured crystals characterized by spherulitic, branching or dendritic morphologies that occur in layers near the flow surface. Well-known examples are the...

Fractal forms—complex shapes which look more or less the same at a wide variety of scale factors, are everywhere in nature. From the fluctuations in the cosmic microwave background radiation to the coastlines of continents, courses of rivers, clouds in the sky, branches of plants and veins...

Iceberg Jan01

Iceberg

Check out these photos of banded icebergs that have formed over thousands of years. Some of the stripes were created by layers of the iceberg melting and refreezing, while others were formed from the dust and soil picked up from the original ice sheet when it was sliding down the Antarctic hillside. It’s amazing how these two processes can form such distinctive patterns. These photographs were taken by Norwegian sailor, Oyvind Tangen. via...

Appearing as a slender, horizontal spiral of cloud, cirrus Kelvin-Helmholtz is one of the most distinctive cloud formations. However, it tends to dissipate only a minute or two after forming and, as a result, is rarely observed. Average height is around 16,500...

Rainbows Dec24

Rainbows

Natural rainbows are made up of 6 colors: red, orange, yellow, green, blue and violet. The intensity of each color may vary due to atmospheric conditions and the time of day. The rainbows most of see are actually arcs of perfect circles (with radii of exactly 42 degrees,...

Eery Mammatus Dec23

Eery Mammatus

Mammatus are pouch-like cloud structures and a rare example of clouds in sinking air. Sometimes very ominous in appearance, mammatus clouds are harmless and do not mean that a tornado is about to form; a commonly held misconception. In fact, mammatus are usually seen after the worst of a thunderstorm has passed. As updrafts carry precipitation enriched air to the cloud top, upward momentum is lost and the air begins to spread out horizontally, becoming a part of the anvil cloud. Because of its high concentration of precipitation particles (ice crystals and water droplets), the saturated air...
