THE AMAZING TAJ MAHAL IN INDIA

Taj Mahal is regarded as one of the eight wonders of the world. It was built by a Muslim Emperor Shah Jahan in the memory of his dear wife at Agra.
Taj Mahal is a Mausoleum that houses the grave of queen Mumtaz Mahal. The mausoleum is a part of a vast complex comprising of a main gateway, an elaborate garden, a mosque (to the left), a guest house (to the right), and several other palatial buildings. The Taj is at the farthest end of this complex, with the river Jamuna behind it.
The Taj stands on a raised, square platform (186 x 186 feet) with its four corners truncated, forming an unequal octagon. The architectural design uses the interlocking arabesque concept, in which each element stands on its own and perfectly integrates with the main structure. It uses the principles of self-replicating geometry and a symmetry of architectural elements.
Its central dome is fifty-eight feet in diameter and rises to a height of 213 feet. It is flanked by four subsidiary domed chambers. The four graceful, slender minarets are 162.5 feet each. The central domed chamber and four adjoining chambers include many walls and panels of Islamic decoration.
Taj Mahal is built entirely of white marble. Its stunning architectural beauty is beyond adequate description, particularly at dawn and sunset. The Taj seems to glow in the light of the full moon. On a foggy morning, the visitors experience the Taj as if suspended when viewed from across the Jamuna river.

KOMODO DRAGON

Do you know what is the largest lizard? This lizard is called komodo. It lives in the scrub and woodland of a few Indonesian islands.

Komodo dragon is the world's heaviest lizard, weighing 150 pounds or more. The largest Komodo ever measured was more than 10 feet (3 meters) long and weighed 366 pounds (166 kg) but the average size of komodo in the wild is about 8 feet (2.5 meters) long and 200 pounds (91 kg)

Komodo has gray scaly skin, a pointed snout, powerful limbs and a muscular tail. They use their keen sense of smell to locate decaying animal remains from several miles away. They also hunt other lizards as well as large mammals and are sometimes cannibalistic.

The Komodo dragon's teeth are almost completely covered by its gums. When it feeds, the gums bleed, creating an ideal culture for virulent bacteria. The bacteria that live in the Komodo dragon's saliva causes septicemia, or blood poisoning, in its victims. A dragon will bite its prey, then follow it until the animal is too weak to carry on.

This lizard species is threatened by hunting, loss of prey species and habitat loss.

RAIN FOREST

Rain forests cover about 10% of the earth, but they contain 90% 0f the world’s animals and plants. Rain forests are found in the hottest parts of the earth. They are situated in the area from the Tropic of Cancer to the Tropic of Capricorn. This is the area on both sides of the Equator.
These forests are called rain forests because it usually rains there everyday. The weather is always hot and humid. The main rain forests are in America, Africa, and Asia. The largest area of rain forest is Amazonian in South America. It is three times larger than the whole of Indonesia.
Indonesia was covered by rain forests, but many of its forests have been cut down. Some fire also destroyed the Indonesian forests, especially during the dry season. It is hard now to reforest the bare land.

ELEPHANT

An elephant is the largest and strongest of all animals. It is a strange looking animal which it has thick legs, huge sides and backs, large hanging ears, a small tail, little eyes, long white tusks and above all, elephant has a long nose, the trunk. An elephant is commonly seen in a zoo, it has hard found in it natural habitat.
The trunk is the elephant's peculiar feature. This trunk has various usages. The elephant draws up water by its trunk and can squirt the water all over its body like a shower bath. The elephant's trunk also lift leaves and put them into its mouth. In fact, the trunk serves the elephant as long arm and hand. An elephant looks very clumsy and heavy and yet an elephant can move very quickly.
The elephant is very intelligent animal. Its intelligence combined with its great strength makes an elephant a very useful servant to man. Elephant can be trained to serve in various ways such as carry heavy loads, hunt for tigers and even fight. An elephant is really a smart animal.

MANGROVE TREES

A mangrove is a tropical marine tree. Mangroves have special aerial roots and salt-filtering tap roots which enable them to thrive in brackish water. Brackish water is salty but not as salty as sea water. Mangrove trees are commonly planted and found in coastal areas. Mangroves can serve as walls of protection for natural disaster in coastal area like tsunami. According to BBC News, healthy mangrove forests had helped save lives in the Asia disaster tsunami and people tended to respect these natural barriers even more, especially after the tsunami.
There are several species of mangrove tree found all over the world. Some prefer more salinity, while others like to be very-close to a large fresh water source such as river. Some prefer areas that are sheltered from waves. Some species have their roots covered with sea water every day during high tide. Other species grow on dry land but are still part of the ecosystem. The Times of India reported that rare species of mangrove had been found and was also known as the looking-glass tree, probably because the leaves are silver-coated.
Mangroves need to keep their trunk and leave above the surface of the water. Yet they also need to be firmly attached to the ground so they are not moved by waves.
Any part of root that appears above the water flows oxygen to the plant under water surface. as the soil begin to build up, these roots procedure additional roots that become embedded in the soil.

WHAT IS TORNADO?

Tornadoes are known as one of the most damaging disasters. What is the description of tornadoes? A tornado is a very powerful column of winds which spirals around a center of low atmospheric pressure. A tornado will look like a large black funnel which hangs down from a storm cloud.

The name "tornado" derives from the Latin "tonare". It means "to thunder." While the Spanish developed the word into "tornear" which means "to turn or twist". This is why a tornado is sometimes called twister or cyclone.

The winds inside a twister can spin around at speeds up to 500 miles an hour, but it usually travels at roughly 300 miles an hour. This speed twisting makes a tornado the most dangerous storm.

The average tornado has a diameter of about 200 to 300 yards. The smaller tornadoes are known as satellite tornadoes. These small offspring, about 50 yards across, can be very fierce and do lots of damage.

The forming of a tornado can be very quick. Sometimes it can form in a minute or less. A tornado can travel across the ground at high speeds, then it can suddenly vanish. Most tornadoes last less than twenty minutes and travel less than 15 miles. However, the super storms sometimes travel over 100 miles before they are exhausted.

KINDS OF EARTQUAKE

Earthquake often happens around us. It brings great damages. Earthquake is hard to be predicted and that makes lot victims.

Actually there are three kinds of earthquake. This kinds of earthquake are commonly base on the factor and geological area where the earthquakes happen. These three kinds of earthquake are tectonic, volcanic and explosion.

Tectonic earthquakes is most common one. This kind of earthquake happens while earth's crust rocks break because of the geological strength created by moving of the earth's plates.

Volcanic earthquakes happen exactly with volcanic activity. Volcanic earthquakes are when the volcano produces acidic lava, which drys quickly, when it drys quickly it blocks the top of the volcano. This make no more magma can escape. Pressure starts to build up and eventually the acidic lava can no longer stand the pressure. So the volcano is free to explode, the pressure is released so fast that an earthquake is caused. A volcanic earthquake is usually kept within 10-20 miles of the volcano.

Explosion earthquakes are the result of the collapse earthquakes that are small earthquakes occurring in underground mines and caverns.

TYPES OF VOLCANO ERUPTIONS

Volcanic eruptions have caused some of the worst disasters in the world. They can wipe out entire cities and kill thousands of people.
The name of volcano comes from Roman term. It derives from VULCAN which is the name of Roman fire god. Romans believed that Vulcan lived on a volcanic Italian coast. Romans called the island VULCANO.

According to scientists, volcanic eruptions are divided in to four basic groups. They are commonly known as Hawaiian, Strombolian, Vulcanian and Peleean. The term of Hawaiian eruptions are named after the volcanoes in Hawaii. These volcanic eruptions are the least violent type. They produce highly fluid lava which flows quietly. This gradually builds up a shield volcano.

Strombolian eruptions are named after Stromboli. These result from the constant release of gas from the magma. As the gas escapes, it produces tephra that piles up, turning into a cinder cone. Strombolian eruptions happen when sticky magma plugs the central vent. This makes the magmatic gas build up pressure until it blasts. The magma is turned into volcanic dust and bombs.

Vulcanian eruption which comes from the ancient Roman belief, are more violent than the strombolian eruption. Vulcanian eruption happens and brings magma which is more viscous. Vulcanian explosions are usually larger and noisier than the Strombolian eruptions.

Paleean eruptions are famous as the most violent kind of volcanic eruptions. The name of paleean comes from the eruption of Mount Pelee, Martinique in 1902. It killed almost 38 thousands people. A Peleean eruption occurs when the magmatic gas build up tremendous pressure. This causes violent explosions with glowing clouds of hot ash and dust.

PLATYPUS

Many people call platypus duckbill because this animal has a bill like duckbill. Platypus is a native Tasmania and southern and eastern Australia.
Platypus has a flat tail and webbed feet. Its body length is 30 to 45 cm and covered with a thick, and woolly layer of fur. Its bill is detecting prey and stirring up mud. Platypus' eyes and head are small. It has no ears but has ability to sense sound and light.
Platypus lives in streams, rivers, and lakes. Female platypus usually dig burrows in the streams or river banks. The burrows are blocked with soil to protect it from intruders and flooding. In the other hand, male platypus does not need any burrow to stay.

HUMAN BODY ENERGY

Human body is actually a living machine and is like all other machines. This living machine needs fuel to supply it with energy. The fuel is provided by the food which we eat. However do we know how much we need to stay healthy?
The energy value of food is usually measured in calories. A calorie is the amount of heat which is required to raise the temperature of 1 kg of water by 1 degree C. The number of calories which people need per day varies. It depends on the activity which the people are involved in. For example; people will need more calories for standing than for sitting, people need more for running than for walking, etc.
The energy which is provided by food is in the form of three kinds of chemical substances. They are carbohydrate, protein and fat. Carbohydrate provides 8.8 calories per gram (cal/gm) of energy, protein 4.0 cal/gm and fat 8.0 cal/gm. Each food contains different proportion of these substances.These three chemical substances are all important for body staying healthy.
