Amazing dwarf animals

Many of the animals inhabiting the land are considered large and powerful. Sometimes, however, the evolution is moving in strange directions . Often as a result of living in isolation and safety animal may start to lose the need for large amounts , and each successive generation will be a little less.

Dwarf elephants
In many Mediterranean islands are the remains of small elephants, known as dwarf . This phenomenon is called insular dwarfism . Over time, due to the isolation a kind of animal is reduced in size . Dwarf elephants evolved from large , who came to these islands before the water level rose . The smallest elephant weighed 200 kg and was 90 cm tall Unfortunately, most dwarfs died 11 thousand years ago, when the Earth's climate became warmer and the weather changed.

Dwarf antelope
Dwarf antelope is the smallest of all antelopes . Its height of just 25 cm , weight - 3 kg. Its size antelope not received because of the isolation , as other animals , and because of their diet. Antelope herbivores , and each species eats different types of leaves. One tree can feed any number of antelope , as at different heights different foliage . Ancestors dwarf antelope eat the foliage growing below , but because of competition with other small antelopes , this animal had just the same decrease in size . Dwarf antelopes live in the tropics of West Africa and feed on leaves in the undergrowth . They are very cautious and shy and only come out at night. Surprisingly, if they scare these antelopes, avoiding the danger can jump into the air at 2.5 m It is as if a man could jump up to 18 m .

Pygmy buffalo
Sulawesi , one of the islands in Indonesia , live dwarf buffalo, two species of dwarf water buffalo : plains and mountain Anoa Anoa . Water buffalo usually 3 m in length , 2 m in height, and they weigh over 1000 pounds. In contrast, mountain pygmy buffalo only 70 cm in height , 1 m in length and weigh them is 200 kg . Flat Anoa not much more. Size of these small buffalo fashionable to compare with the dog. Unlike cows Anoa live alone or in pairs, eat leaves and grass. They are often hunted for their skins , which are of good quality . As a result, this species is endangered.

Virginia kruglopaly gecko
One of the three Virgin Islands is home to the small reptile in the world. The length of this gecko is 18 mm, and weight 0.15 g They live on the slopes of the hills and hide in relatively moist crevices between the stones . Because of their small size , they do not find easy, so the exact number of the population is difficult to say . Because of their small size, they lose moisture two times faster than their larger cousins, so dwarf geckos prefer moist places, and they breed only when a lot of water around .

Cypriot pygmy hippo
Cypriot pygmy hippopotamus hippos extinct species inhabiting the island of Cyprus from the Pleistocene until the early Holocene. Their height is 75 cm and length 120 cm, weight 200 kg. The smallest surviving hippos slightly larger in size and are known as pygmy hippos live in West Africa. They left in the wild only 3000

enfield-escorts made a real revolution in the industry.



Earth seems to us so big so reliable and so much to us that we do not notice it a secondary position in the family of planets.
Weak only consolation is that the Earth - the largest of the terrestrial planets . In addition, it has the atmosphere of average power , much of the earth's surface is covered with a thin layer of non-uniform water. And it revolves around the majestic companion , whose diameter is equal to a quarter of the earth's diameter .
However, these arguments are hardly enough to maintain our cosmic self-importance . Tiny on an astronomical scale , the Earth - our home planet , and so it deserves careful study. After a painstaking and hard work of many generations of scientists have conclusively proven that the Earth is not the " center of the universe " and the most common planet , ie cold ball , moving round the Sun.

In accordance with the laws of Kepler Earth orbits the Sun at a variable rate slightly elongated ellipse. Closest to the sun it is appropriate at the beginning of January, when the Northern Hemisphere winter reigns , departs furthest in early July, when we have summer. The difference in the distance of the Earth from the sun between January and July is about 5 million km. So winter in the northern hemisphere just a little warmer than in the South , and summer , on the contrary , a little bit cooler. This is more clearly just makes itself felt in the Arctic and Antarctica.

The ellipticity of the orbit of the Earth exerts on the nature of the seasons is indirect and very little impact . The reason for the change of seasons is in the tilt of Earth's axis . Earth's axis is at an angle of 66 ° to the plane of its motion around the Sun. For most practical purposes can be taken that the axis of rotation of the Earth moves in space is always parallel to itself . In fact, the axis of rotation of the Earth, or something the same as the axis of the world, because they are parallel to the celestial sphere describes a small circle , making one complete rotation every 26 thousand years.

In the next hundred years, the north pole of the world will not be far from the North Star , then pulls away from her, and the name of the last star in the handle of the Little Dipper Bucket - Polaris - loses its meaning. After 12 thousand years of peace pole closer to the brightest star in the northern sky - Vega in the constellation Lyra.

The described phenomenon is called the precession of the Earth's rotation axis . Discovered the phenomenon of precession has Hipparchus , who compared the positions of the stars in its catalog with a composed long before his star catalogs and Aristilla Timoharisa . Compare directories and Hipparchus pointed to a slow displacement of the axis of the world.

There are three exterior shell of the Earth: the lithosphere , hydrosphere and atmosphere. Beneath the lithosphere realize solid top cover of the planet, which serves as the ocean floor , and on the continents the same as the land. Hydrosphere - is groundwater , water, rivers, lakes , seas, and finally the ocean . Water covers 71 % of the Earth's surface. The average depth of the oceans 3900 m

Ten Wonders of Nature that could disappear by 2030

Travel Website Budget Travel has compiled a list of the ten wonders of nature, which may disappear by 2030.

The Belize Barrier Reef has suffered greatly in 1998 , losing in many places up to 50 % of the corals . His corals, as before, discolored - both because of global warming , and because of human activities.

Congolese Basin .
Congolese Basin - the second area of ​​the array after the Amazon jungle . By 2040, up to two -thirds of the unique flora and fauna, according to the UN will be lost in the event of lack of effective measures to protect them.
Forests are cut down relentlessly to pastureland , mines, and during the guerrilla war in this region of Africa . Reduction of the area of forest surface leads to a reduction in carbon dioxide absorption , and hence rainfall, which contributes to climate change.

Dead Sea.
Over the past four decades of its area was reduced by one third, and it became shallow at 24 meters . Former beaches are now one and a half kilometers away from the coastline. The water in the Dead Sea comes only from the Jordan River , but the surrounding countries are taken out of the river , more water.
As a result, after 50 years of the Dead Sea does not become. Moreover, that manufacturers of cosmetics and potash constantly depleting mineral resources of the seabed.

Everglades National Park ( Florida , USA).
Marshes , which occupy most of its territory , subject to contamination from the surrounding farms, and the invasion of creatures from outside the park.
Plus, there's the fact that 60 % of the local water supply is pumped to the nearby town and on the farm.
As a result, the area of the park - the only place where dwells the Florida panther - has fallen by half since 1900. For 40 years, the Florida panther, as well as 20 more species may disappear completely .

Madagascar .
If you do not save the forests of the island of the African state , after 35 years, they will be completely cut down and burned and their inhabitants will die . Reserves occupy only 5 % of the island , not allowing animals to safely navigate around Madagascar.
Some rare species of the island have not even been studied and recorded, and may die before they have time to explore.

Maldives .
If global warming continues , these islands that rise only a little over two meters above sea level, will be flooded . In 2008, the president of the state has announced the acquisition of land in other countries , particularly in India , for the settlement of the citizens who were forced to leave their homes , flooded the ocean. In 2009 , to emphasize the imminent danger, he chaired a meeting of the government under water.

North and South Poles .
Global warming threatens the extinction of 80% of the emperor penguins of Antarctica. In the Arctic, the same destruction threatens polar bears , because together with the melting of the polar ice caps are killed whole ecosystems , including food chain. New ice packs will cease to form in Antarctica for 20-40 years.

The population of tigers.
More than half the world's tigers live in India. All in the world in the wild they left about 3-4 thousand, whereas in 1900, India alone there were 100,000 . Fully tigers can become extinct within 12 years. To meet the needs of traditional Chinese medicine are killing an average of one tiger per day. Tiger reserves exist, but they do not provide reliable ways of migration of females needed for a complete reproduction of the population.

Tahuamanu Jungle ( Peru).
In the Peruvian province of Madre de Dios are almost the world's last reserves of mahogany . And it is growing in the jungle Tahuamanu . But because of illegal logging are shrinking . About 80% of mahogany buying dollars. Because of each tree can make furniture for a million dollars .
Loggers build roads , allowing you to enter the jungle to farmers and hunters , and this, in turn, disturbs and destroys the indigenous ecosystem.

Yangtze River basin .
Many observers, including Chinese officials have acknowledged that most of the species of flora and fauna that inhabit this natural region is under threat of destruction.
The reason for that is deforestation, dam construction and reservoir formation . There is also the risk of an earthquake.
Tourist flows can have a twofold impact on the corners of nature : on the one hand, they obviously impair the ecological condition of unique places of the Earth, only hastening their death. On the other hand, local governments can spend the revenue from tourism on the conservation of natural wonders .

15. Moon is moving away from Earth.

Measurements, carried out here for the past 25 years, clearly show that the orbit of the moon is increasing, and it is moving away from Earth.

In general, this occurs at a speed of 4 cm per year. However, astronomers have predicted that when the sun enters into the red giant phase - in about 5 billion years - Earth and Moon, came under the influence of increased its atmosphere, come closer again.

During this period, the moon will come to Earth as close as ever - it will be at a height of 18,470 km. over our planet at a point, called the "Roche limit."

As a result, the Moon will be torn to pieces and scattered to form a big ring of debris diameter of 37,000 km. above the equator of the Earth, like a ring of Saturn.

The movement of rocks

The land on which we walk, made ​​of recycled materials. During certain cycles of volcanic rocks turn into sedimentary rocks and metamorphic rocks, and then all over again. This cycle is not perfect: the magma from the earth rises and cools and turns into volcanic rock. Tectonic processes raise the rock to the surface, where erosion destroys it. The tiny fragments are formed, and the pressure compresses and transforms them into the sediment, such as sandstone. If the sediments accumulate deeper, they can turn into metamorphic rocks under high pressure and at high temperature. During the process of sedimentary rocks can be destroyed, and metamorphic rocks to climb higher. But if metamorphic rocks will move deeper in the kinks when one pushes the other layers, these species will eventually become magma again, and the process is repeated.
