Snake Caught by Spider’s Web !!..

Very few spiders in the world are known to bite others as a defensive strategy or/and as a natural inheritance. Nearly all spiders are venomous, but few are dangerously poisonous. Most spiders will attempt to escape, but they may bite if cornered. Look, they don’t care the type of the victim.

Bora Bora island – the fantasy on the Earth!!..

Bora Bora is an island in the overseas territory of France in the Pacific Ocean. The island, located about 230 km away and is surrounded by a lagoon and a barrier reef. In the center of the island are the remnants of an extinct volcano rising to two peaks.

The most dangerous Bird in the world !!..

According to the Guinness Book of Records, the Cassowaries are the world’s most dangerous birds, capable of dealing fatal blows. They are very unpredictable, aggressive creatures, especially if wounded or cornered.

Cassowaries are very large flightless birds native to the tropical forests of New Guinea and northeastern Australia. Normally cassowaries are very shy but when disturbed can lash out dangerously with their powerful legs.

They are capable of inflicting fatal injuries to an adult human. Wounded or cornered birds are particularly dangerous. Cassowaries, deftly using their surroundings to conceal their movements, have been known to out-flank organized groups of human predators.

The Cassowary lives in the rain forests of Australia and New Guinea and are actually pretty shy animals if undisturbed, but if you get to close and it thinks you’re a threat you could receive a bone-breaking kick or get sliced by its dagger-like sharp claws.

During WWII, soldiers stationed in New Guinea were warned to stay away from these birds, but some of them still became victims.

The Cassowary is also one of the most difficult animals to keep in the Zoo because of the frequent injuries suffered by Zoo keepers that look after them.

The meat of the cassowary is said to be very strong in taste and to even make some people a bit dizzy the first time they eat it.

Cassowaries are still part of the diet in New Guinea, where they are either hunted or kept as domestic animals, though this is risky as the birds can escape and if it injures or kills anyone in the village family members will expect compensation or a revenge killing.

This bird can take care of itself, but, unfortunately, this doesn’t seem to help it very much against human cruelty and it is on the endangered species list, along with so many others.

According to researches, the total population of cassowaries is been rapidly reducing, So it would be our duty to protect them although they are the most dangerous birds on earth, and less dangerous than human 🙂

Lost Cities in the World !!…

(1) Troy

Myth, folklore, mystery, and intrigue surround the ancient city of Troy like no other ruin on Earth. Once thought to be purely imaginary, a prop in Homer’s epic poem The Iliad, excavations in northwestern Turkey in 1871 eventually proved that the city indeed existed.

In 1871, German adventurer Heinrich Schliemann began digging at Hisarlik, Turkey, (shown here) in search of the fabled city. His roughshod excavation wrought havoc on the site, but revealed nine ancient cities, each built on top of the next and dating back some 5,000 years. At the time, most archaeologists were skeptical that Troy was among the ruins, but evidence since the discovery suggests the Trojan capital indeed lies within the site.

(2) Mohenjo Daro

The Indus Valley civilization was entirely unknown until 1921, when excavations in what would become Pakistan revealed the cities of Harappa and Mohenjo Daro (shown here).

This mysterious culture emerged nearly 4,500 years ago and thrived for a thousand years, profiting from the highly fertile lands of the Indus River floodplain and trade with the civilizations of nearby Mesopotamia.

(3) Tadmor

There is evidence that the ancient city of Palmyra, also known as Tadmor, was in existence as far back as the 19th century B.C. Its importance grew around 300 B.C. as trading caravans began using it as a way station between Mesopotamia and Persia. Palmyra’s strategic location and prosperity attracted the interest of the Romans, who took control of the city in the first century A.D.

Catching an Anaconda – Unbelievable

The Earth….

From the perspective we get on Earth, our planet appears to be big and sturdy with an endless ocean of air. From space, astronauts often get the impression that the Earth is small with a thin, fragile layer of atmosphere. For a space traveler, the distinguishing Earth features are the blue waters, brown and green land masses and white clouds set against a black background.

Many dream of traveling in space and viewing the wonders of the universe. In reality all of us are space travelers. Our spaceship is the planet Earth, traveling at the speed of 108,000 kilometers (67,000 miles) an hour.

Earth is the 3rd planet from the Sun at a distance of about 150 million kilometers (93.2 million miles). It takes 365.256 days for the Earth to travel around the Sun and 23.9345 hours for the Earth rotate a complete revolution. It has a diameter of 12,756 kilometers (7,973 miles), only a few hundred kilometers larger than that of Venus. Our atmosphere is composed of 78 percent nitrogen, 21 percent oxygen and 1 percent other constituents.

Earth is the only planet in the solar system known to harbor life. Our planet’s rapid spin and molten nickel-iron core give rise to an extensive magnetic field, which, along with the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth’s atmosphere protects us from meteors, most of which burn up before they can strike the surface.

From our journeys into space, we have learned much about our home planet. The first American satellite, Explorer 1, discovered an intense radiation zone, now called the Van Allen radiation belts. This layer is formed from rapidly moving charged particles that are trapped by the Earth’s magnetic field in a doughnut-shaped region surrounding the equator. Other findings from satellites show that our planet’s magnetic field is distorted into a tear-drop shape by the solar wind. We also now know that our wispy upper atmosphere, once believed calm and uneventful, seethes with activity — swelling by day and contracting by night. Affected by changes in solar activity, the upper atmosphere contributes to weather and climate on Earth.

Besides affecting Earth’s weather, solar activity gives rise to a dramatic visual phenomenon in our atmosphere. When charged particles from the solar wind become trapped in Earth’s magnetic field, they collide with air molecules above our planet’s magnetic poles. These air molecules then begin to glow and are known as the auroras or the northern and southern lights.

The Earth is divided into several layers which have distinct chemical and seismic properties (depths in km):

Tectonic plates

According to plate tectonics theory, the outermost part of the Earth’s interior is made up of two layers: the lithosphere, comprising the crust, and the solidified uppermost part of the mantle. Below the lithosphere lies the asthenosphere, which forms the inner part of the mantle. The asthenosphere behaves like a superheated and extremely viscous liquid.

The lithosphere essentially floats on the asthenosphere and is broken up into what are called tectonic plates. These plates are rigid segments that move in relation to one another at one of three types of plate boundaries: convergent, divergent and transform. The last occurs where two plates move laterally relative to each other, creating a strike-slip fault. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation can occur along these plate boundaries.
The main plates are
