Polar bears feed mainly on ringed and bearded seals. Depending upon their location, they also eat harp and hooded seals and scavenge on carcasses of beluga whales, walruses, narwhals, and bowhead whales. On occasion, polar bears kill beluga whales and young walruses.
Polar bears get their water from the chemical reaction that breaks down fat. This is why a polar bear's diet is high in fat but low in protein. For example, when they hunt seals, polar bears will eat the blubber, but leave the rest behind for scavengers.Sep 27, 2003
Ask any child what color a polar bear is and s/he will exclaim, “white” with great enthusiasm, but truth be told, their fur is actually transparent and holds no color. It only appears white because it reflects visible light. They're nearly invisible under infrared photography.Feb 27, 2014
CLEAR! But if the Polar bear's skin is black, how come they don't look black in colour? Well, each of the longer guard hairs on the Polar bear's body is hollow and reflects visible light, much like snow. So when the sun is shining brightly, Polar bears appear bright white.Jan 4, 2012
A Polar bear's coat has two layers of hair: an outer layer, made up of long (5-15cm) guard hairs; and a thick undercoat, made up of shorter hair. These guard hairs are mostly transparent or clear, but thanks to some special characteristics that work to create cool optical tricks, these hairs appear white.Nov 2, 2012
Believe it or not, their hair isn't actually white! Their long outer hairs, which protect their soft, thick undercoat, are mostly hollow and transparent. The thinner hairs of their undercoat are also colorless. Polar bear hair looks white because the air spaces in the hairs scatter light of all colors.
Polar Bears can live 20-30 years but only a small amount of polar bears live past 15-18 years.in captivity a polar bear has lived to be 45 years old but in the wild the longest living polar bear was known to be 32 years old.
Rocks tell us a great deal about the Earth's history. Igneous rocks tell of past volcanic episodes and can also be used to age-date certain periods in the past.

Grizzly bear will always win in head to head fight with African lion because grizzlies are stronger, taller, and heavier. They also have the bigger paws with stronger deadly swipes than lion, though they are smaller than polar bear but still they are the stronger and dangerous than all other bears in the world.Aug 14, 2014
"If it's a fight between a 1,200-pound male polar bear and a 600-pound grizzly, I think we know who would win," Dr. Rockwell said. "But in this likeliest of cases, it's debatable. There are actually reports in the literature where grizzlies have killed denning polar bear females."Feb 23, 2010
The largest male weighed 2,210 lbs. That said, the largest bear found was a Kodiak: he was 14 feet tall and 2500 lbs. On average, however, the Kodiak is 800-1500 lbs and stand 5-10 feet tall. Overall, they're much more dense than Polar Bears, but Polars are still bigger.

Nuclear energy is the energy that holds together the nuclei of atoms. Atoms are the most simple blocks that make up matter. Every atom has in its center a very small nucleus. ... Nuclear fusion is the combining of two light atoms into a heavier one and nuclear fission is the splitting of a heavy atom.
Nuclear energy can be used to create electricity, but it must first be released from the atom. In nuclear fission, atoms are split to release the energy. A nuclear reactor, or power plant, is a series of machines that can control nuclear fission to produce electricity.May 24, 2011
In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use nuclear fission to produce electricity.
A clean energy resource. Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. The term includes nuclear fission, nuclear decay and nuclear fusion. ... There is a social debate about nuclear power.
These are the only major accidents to have occurred in over 17,000 cumulative reactor-years of commercial nuclear power operation in 33 countries. The evidence over six decades shows that nuclear power is a safe means of generating electricity. The risk of accidents in nuclear power plants is low and declining.
13% of the world's electricity comes from nuclear power plants that emit little to no greenhouse gases. ... The U.S. saves $12 billion dollars each year for energy costs because of nuclear power. Nuclear power plants actually emit fewer radioactive materials into the environment than a traditional coal-burning plant.Dec 26, 2014
Nuclear energy is clean, reliable and affordable. ... The economics of nuclear energy generation depend on its capacity to produce enormous and uninterrupted amounts of electricity over long periods, with affordable and stable electricity costs. Nuclear generating plants can operate for 60 years or more.
Nuclear power plants are expensive to build but relatively cheap to run. In many places, nuclear energy is competitive with fossil fuels as a means of electricity generation. Waste disposal and decommissioning costs are usually fully included in the operating costs.
If the Nuclear Energy Agency (NEA) has accurately estimated the planet's economically accessible uranium resources, reactors could run more than 200 years at current rates of consumption.
Men's gymnastics was on the schedule of the first modern Olympic Games in 1896, and it has been on the Olympic agenda continually since 1924. Olympic gymnastic competition for women began in 1936 with an all-around competition, and in 1952 competition for the separate events was added.

On 23 December 1888, Vincent van Gogh cut off his ear. He took it to a prostitute in a hotel in Arles in southern France where he was living at the time. The painter died one and a half years later following a suicide attempt.
Van Gogh suffered from psychotic episodes and delusions and though he worried about his mental stability, he often neglected his physical health, did not eat properly and drank heavily. His friendship with Gauguin ended after a confrontation with a razor, when in a rage, he severed part of his own left ear.
He is known as the tortured genius who cut off his own ear as he struggled with mental illness after the breakdown of his friendship with a fellow artist. But a new study claims Vincent Van Gogh may have made up the story to protect painter Paul Gauguin who actually lopped it off with a sword during an argument.May 4, 2009
Late Sunday evening December 23, 1888, Vincent Van Gogh, then 35 years old, cut off the lower half of his left ear and took it to a brothel, where he asked for a prostitute named Rachel and handed the ear to her, asking her to "keep this object carefully."
It shows the artist in three-quarter profile standing in a room in the Yellow House wearing a closed coat and a fur cap. His right ear is bandaged. It was in fact his left ear that was bandaged, the painting being a mirror image. To his right is an easel with a canvas on it.
Every year, approximately 250,000 bulls are killed in bullfights. The animals are stabbed multiple times before suffering slow, agonizing deaths in front of an audience, including children. Animal cruelty is not entertainment. You can help by not attending bullfights.
When Earth formed 4.6 billion years ago from a hot mix of gases and solids, it had almost no atmosphere. The surface was molten. As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere.
Answer 1: Earth´s inner core and outer core are both made of an iron-nickel alloy. The state of matter (solid, liquid or gas) of a given material depends on its temperature and pressure. Most materials, including iron and nickel, change from liquid to solid at lower temperatures and/or higher pressures.
Above the inner core is the outer core, a shell of liquid iron. This layer is cooler but still very hot, perhaps 7,200 to 9,000 degrees Fahrenheit (4,000 to 5,000 degrees Celsius). It too is composed mostly of iron, plus substantial amounts of sulfur and nickel.
Don't be surprised if you get pinched. No surprise, it's an entirely American tradition that probably started in the early 1700s. St. Patrick's revelers thought wearing green made one invisible to leprechauns, fairy creatures who would pinch anyone they could see (anyone not wearing green).Mar 17, 2010
However, unlike many other U.S. cities, Seattle has many more "rain days", when a very light drizzle falls from the sky for many days. In an average year, at least 0.01 inches (0.25 mm) of precipitation falls on 150 days, more than nearly all U.S. cities east of the Rocky Mountains.
Snowfall is 3 inches. The average US city gets 26 inches of snow per year. The number of days with any measurable precipitation is 100. On average, there are 144 sunny days per year in Portland, Oregon.
