General knowledge/ most surprising things :
481. Tsunamis, often wrongly called tidal waves. They are not caused by tides or even by the wind, but by underwater earthquakes, landslides or volcanic eruptions. These disturbances cause the sea bed to move very quickly, which shifts a large amount of water and disrupts the sea surface. Tsunamis travel extremely fast – up to 750km/h. They have a long wavelength, their crests often being 150km apart, so that a crest passes only every 15 minutes or so. The shores of the Pacific more than those of any other ocean have been damaged by tsunamis because volcanic eruptions and earthquakes occur frequently in that area.
482. Tides result from the regular rise and fall of the water level in the oceans. This phenomenon is caused by the gravitational pull of the Moon and Sun on the Earth and by the centrifugal force generated by the rotation of the Moon-Earth system as a whole. These two forces act in opposite directions. The solar tide has a period of 12.41 hours because of the monthly rotation of the Moon around the Earth
483. A few hundred meters below the ocean’s surface it is dark because light cannot penetrate to those depths. Blue light penetrates water farther than red or violet light, and because more blue light is returned to the surface without being absorbed, the open ocean usually looks blue in color. Seawater may look blue-green when it contains a large amount of phytoplankton – tiny plant-like organisms that contain chlorophyll. The yellow-brown sea found in coastal regions probably gets its coloring from mud, sand or pollution.
484. Acadia National Park is over forty seven thousand acres of beautiful eastern scenery and landscape and one of the most visiting National Parks in the United States of America. Acadia National Park was the first National park to be develop east of the Mississippi river in the United States. It was created in 1916 and first called the Sieur de Monts National Monument and then the Lafayette National Park, before it took on it’s name of the Acadia National Park in 1929 which means it’s a land of plenty in the Greek terminology. If you’re visiting the Acadia National Park in the United States, check out the amazing ponds in Acadia including the Jordan pond and enjoy the greens and blues of the quiet rivers and lakes.
485. Nocturnal animals have highly developed senses. Their sense of hearing, sight and smell are specially adapted, to make the most of night-illumination. Some nocturnal animals have vision that is easily adapted to night and day illumination The bodies of nocturnal animals have special adaptations to enable them to survive the dark. Nocturnal animals like lemurs have special eyes, while bats use echolocation. Echolocation refers to the bat’s ability to emit a high-pitched sound. The sound bounces off objects within range and gives the animal information about the shape, distance and direction of the object. Nocturnal animals like rabbits have an extra powerful sense of hearing.
486. The traditional art of the Aborigines/ Bradshaw painting is one of oldest and most popular of rock paintings. was focused on portraying and narrating the stories of the “Dreamtime”, a creation myth of the Aborigines. Some Aboriginal art works depict the world around them. Kangaroos, crocodiles and kookaburras are included in these paintings. Certain paintings depict the skeleton and organs of people and animals. The colors used in ancient Aboriginal art were natural shades of earth colors such as red, brown and yellow. The other colors used were white made from pipe clay and charcoal made by burning wood.
487. Believe it or not, pigs are smarter than dogs! And dirty little piggy is not only the smartest animals on the planet, but also one of the cleanest animals around.
488.Believe it or not , Crows can count, differentiate between complex shapes and also carry out observational learning tasks. The New Caledonian Crow has been found to create knives to cut leaves and stalks of grass.
489. A rat’s psychology is similar to humans and therefore they are mostly used for lab experiments. Rats possess a mental ability called the met cognition that is seen only in humans and some primates. They can use their keen sense of smell and hearing to detect landmines and bombs. They can even identify human sputum samples containing tuberculosis bacteria.
490. The African Grey Parrot is a native of the West and Central African rainforest. Parrots can mimic human speech, but African Grey parrot can do a step further. They can associate words and their meanings to form sentences
