Catctus Plant: Use And Very Beautiful Images Collection

Introduction Of Cactus Plant:

Cactus is a kind of plant. The plural of cactus can be cacti or cactuses or cactus. In science all genera of cacti (as the whole) are named Cactaceae.

Cacti first came from North America or South America. Many people like to grow cactus in pots or gardens. Now cacti have spread to many other parts of the world.

Many cacti live in dry places, such as deserts. Most cacti have and sharp thorns (stickers) and thick skin. There are many shapes and sizes of cacti. Some are short and round; others are tall and thin. Many cactus flowers are big and beautiful. Some cactus flowers bloom at night and are pollinated by moths and bats. Some cactus fruits are brightly coloured and good to eat. Goats, birds, ants, mice, bats and people eat cactus fruits.

Use:

A cactus may be used for decoration, as the main colorful, vegetative form in a desert environment. It may be used for drink, such as tequila. It may be used for employment, such as the crew of pollinators that make cactus fruits and seeds possible from cactus flowers. It may be used for environmental health, through the carbon dioxide that it takes in and the oxygen that it releases through its stomata, or breathing pores. It may be used for people and wildlife finding their way, through its landmark forms in the monotonous desert environment. It may be used for food, such as the berries and vegetables that the prickly pear cactus [Opuntia spp] offers. It may be used for making money, such as through the dyes that are produced by cochineal insects(Dactylopius coccus) on the prickly pear cactus. It may be used for shelter, such as the nesting cavities that the giant saguaro cactus [Carnegiea gigantea] offers to the Gila woodpecker (Melanerpes uropygialis). It may be used for soil and water conservation, through its soil holding and water intaking roots. It may be used for tools, such as the living fences that people make from any columnar cactus plant.

Igloo Facts History Basics Form Function Use and Very Beautiful Images Collection

Facts Of Igloo:

Igloos are remarkable structures built by many cultures living in particularly cold and snowy areas. Made from the very ice and snow dominating the landscape.They provided an ingenious shelter from the frigid temperatures for families and whole communities. Their unique structure and use lead to them having several interesting properties.

History:

The igloos have been in use by Inuit and certain Native North American tribes for centuries. Their use has not spread much beyond these regions. Pictures of igloos have been found for centuries, as when the explorer Martin Frobisher noted them in his journey in the 16th century. The oldest film of an igloo being built is "Nanook of the North," where the details of an igloo's construction are given.

Basics:

The term "igloo" is derived from the Inuit word "iglu," which simply means "house." Igloos became highly used by the Inuit and other civilizations because of their general convenience. A skilled builder could construct one in about an hour, and the igloo could withstand great forces, whether it be a fierce Arctic wind or a polar bear.

Form:

The igloo is built with blocks of snow that has been compressed and is especially compact. The snow is cut, usually with a saw or knife, and shaped to fit a particular position. No other supports or tools are needed in the igloo's construction. The blocks are used in spirals to form a dome shape. The igloo will usually be built into a snow drift, with a hole left in the ceiling for ventilation of smoke, and the entrance will be built below the igloo itself, with a short tunnel leading out to the open air.

Function:

The purpose of a lowered entrance, like most features of the igloo, is to keep warm air in. The lowered entrance creates a "cold trap" in which body and fire heat cannot escape. The compacted snow will melt on the inside, but the water will fall down the domed walls and soon refreeze, creating an additional support and insulator. With the fresh snow falling on the outside, this cycle makes a continuous loop that keeps the igloo an effective shelter. Sometimes, blankets can be hung on the outside of the igloo for additional insular effects.

Use:

Smaller igloos can be used as temporary structures for hunters and travelers, because of their ease of construction. Usually, though, permanent igloos are large and house an entire family. Occasionally, several families inhabit one igloo. Many times, the bigger igloos are connected through tunnels and the entire community can move through for festivals and celebrations.

Earthquake Introduction Cause Effect And Images

Introduction:

An earthquake is the result of a sudden release of energy in the Earth's crust that create sseismic waves. Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale, also referred to as the Richter scale. These two scales are numerically similar over their range of validity. Magnitude 3 or lower earthquakes are mostly almost imperceptible and magnitude 7 and over potentially cause serious damage over large areas, depending on their depth. The largest earthquakes in historic times have been of magnitude slightly over 9, although there is no limit to the possible magnitude. The most recent large earthquake of magnitude 9.0 or larger was a 9.0 magnitude earthquake in Japan in 2011 and it was the largest Japanese earthquake since records began. Intensity of shaking is measured on the modified Mercalli scale.

Cause:

Earthquakes are caused by tectonic movements in the Earth's crust. The main cause is that when tectonic plates collide one rides over the other causing orogeny earthquakes and volcanoes.The boundaries between moving plates form the largest fault surfaces on Earth. When they stick relative motion between the plates leads to increasing stress. This continues until the stress rises and breaks suddenly allowing sliding over the locked portion of the fault and releasing the stored energy.

Earthquake Effect In As Follows:

1. Shaking and ground rupture

2. Landslides and avalanches
3. Fires
4. Soil liquefaction
5. Tsunami
6. Floods
7.Human impacts

Rainbow Introduction And Very Beautiful Images Collection

Introduction:

A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky, when the Sun shines on to droplets of moisture in the Earth's atmosphere. It takes the form of a ulticoloured arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.In a "primary rainbow", the arc shows red on the outer part, and violet on the inner side. This rainbow is caused by light being refracted while entering a droplet of water then reflected inside on the back of the droplet and refracted again when leaving it.In a double rainbow a second arc is seen outside the primary arc and has the order of its colours reversed red facing toward the other one in both rainbows. This second rainbow is caused by light reflecting twice inside water droplets.

Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind at a low altitude angle. The most spectacular rainbow displays happen when half the sky is still dark with raining clouds and the observer is at a spot with clear sky in the direction of the sun. The result is a luminous rainbow that contrasts with the darkened background.
