Birds
Birds are interesting flying
animals. They are vertebrates and warm blooded animals. They belong to aves
class and they can be found all over the world.
Birds breath with their air pocket. Beside as respiration organ, air pocket also can enlarge or reduce their weight when flying or swimming.
There are many kinds of birds. Earth bird has special characteristic. They have different morphology acording to their food and their habitat. Some of them eat seeds, pollen, fish or meat. There are some species that live in land and the others live in water. Land birds live on their nest.
Female birds have specific tasks. they lay eggs and feed their baby, Beside that they look for foods for their baby.

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.

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.

Earthquake
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.

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.
