Deserts take up about one third (33 percent) of the Earth's land surface.

Deserts are often composed of sand and rocky surfaces.

In hot deserts the temperature in the daytime can reach 45 °C/113 °F or higher in the summer, and dip to 0 °C/32°F or lower in the winter.

The Champions of the Animal KingdomPeople are good at a lot of things, but if animals could enter the Olympics as one team they would probably win almost all the medals! Animals can outrun, outswim, and outjump all humans. Young cheetahs learn to hunt by watching their mother. Later, they start taking part in the hunt. Cheetahs are the fastest land animal and can reach speeds of 113kph in short bursts. ©G.Ellis/GLOBIO.org Fastest Mammal on Land Cheetahs can run up to 113 kph. Fastest Mammal in Water Dall porpoises can swim up to 56 kph. Fastest Flying Bird Peregrine falcons can dive toward the ground at more than 320 kph. Fastest Flightless Bird North African ostriches are the fastest birds on land. They can run at speeds up to 72 kph. They are also the biggest bird. They can weigh 155 kg. Fastest Fish Sailfish can swim up to 109 kph. Loudest Animal The blue whale’s low-frequency pulses are as loud as 188 decibels. This is louder than a jet engine. A blue whale’s call can be detected more than 805 km away. On land, the loudest animals are howler monkeys. Their howls can be heard 4.8 km away.

Arctic terns migrate to and from the Antarctic - about 35,405 km round trip - each year. Among mammals, gray whales and northern elephant seals are the migration champions. They travel up to 20,900 km round trip each year. Deadliest Animal Female Anopheles mosquitoes, which carry and transmit malaria, play a role in the deaths of more than a million people each year. Most Venomous Animal A single sea wasp (a kind of jellyfish with 60 tentacles, each 4 m long) has enough venom to kill 60 adult humans. Strongest Animal The rhinoceros beetle can lift 850 times its own weight

Poison-arrow frogs are social frogs found in Central and South America. They are known by their bright colors which warn other animals that they are poisonous. Its poison is one of the most powerful known and can cause paralysis or death. It is so potent that one millionth of an ounce can kill a dog and an amount smaller than a grain of salt can kill a human. One frog carries enough poison to kill about 100 people. Native hunters use it on the tips of their arrows which is how the frog got its name. Poison-arrow frogs are about the size of a man's thumbnail (less than one inch). The tiny frogs lay their eggs on leaves. When the tadpole hatches, it is carried on one of the parents' back to a bromeliad where the parents feed it small insects, ants, spiders, crustaceans, and tiny water animals. The mother frog may also lay infertile eggs as food for the tadpoles. Poison-arrow frogs are beautiful to look at. Their colors vary from red to yellow to blue. The enemies they encounter are large animals (including humans) who may step on them. Though poison-arrow frogs carry a deadly poison, they are usually harmless if left alone.

The Ocelot is mostly nocturnal and very territorial. It will fight fiercely, sometimes to the death, in territorial disputes. In addition, the Ocelot marks its territory with especially pungent urine. Like most felines, it is solitary, usually meeting only to mate

The bombardier beetle may look innocent enough, but it is famous for being able to spray boiling hot and chemically toxic bodily fluids in the direction of any would-be predator. The bombardier beetle doesn’t exactly melt in your mouth (but it will melt you).

The horned lizard is a seemingly normal looking lizard found in the southwest region of the United States. It doesn’t use its horns to defend itself, as you might expect. Rather, when attacked, it pressures its own sinus cavities until the blood vessels in its eyes burst, and it sprays its attacker with blood from its eyes.

The skunk, or polecat, is actually an attractive little mammal and some people keep them as pets (sans glands, of course). Skunks are omnivores but will turn to trash and carrion when no fresh insects or honeybees, their favorite food, are available. Though their amazing musk can be smelled miles away, their vision is exceptionally weak, and most skunks can only see about 10 feet in front of them. As a result, many are run over – half of all skunk deaths, in fact, are due to humans. All Mustelidae family members (like weasels and ferrets) can spray musk, but skunks are famously the most potent. The skunk’s anal musk is so powerful that if sprayed directly, the victim will experience temporary blindness.

Camel spiders became an Internet sensation during the Iraq war of 2003, when rumors of their bloodthirsty nature began to circulate online. Many tales were accompanied with photos purporting to show spiders half the size of a human. For many years, Middle Eastern rumors have painted camel spiders as large, venomous predators, as fast as a running human, with a voracious appetite for large mammals. The myths are untrue. These creatures do not actually eat camels' stomachs or sleeping soldiers, and they are not so large—but the real camel spider is still an amazing predator. The camel spider's history of misinformation begins with a misidentification. Camel spiders are not even spiders. Like spiders, they are members of the class Arachnida, but they are actually solpugids. Camel spiders, also called wind scorpions and Egyptian giant solpugids (SAHL-pyoo-jids), are only about 6 inches (15 centimeters) long. Photos that purport to show creatures six times that size have misleading perspective—the spider is invariably placed in the foreground where the lens makes it appear much bigger than its actual size. True, they are fast, but only compared to other arachnids. Their top speed is estimated at 10 miles (16 kilometers) per hour. Camel spiders are not deadly to humans (though their bite is painful), but they are vicious predators that can visit death upon insects, rodents, lizards, and small birds. These hardy desert dwellers boast large, powerful jaws, which can be up to one-third of their body length. They use them to seize their victims and turn them to pulp with a chopping or sawing motion. Camel spiders are not venomous, but they do utilize digestive fluids to liquefy their victims' flesh, making it easy to suck the remains into their stomachs.

A Dwarf is a creature from Germanic mythologies, fairy tales, fantasy fiction, and role-playing games. It usually has magical talents, often involving metallurgy. The original concept of Dwarves is very difficult to determine. Sources have gradually given Dwarves more comical and superstitious roles[1]. Dwarves were certainly humanoid, but sources differ over their lifestyles, and their similarity to Elves. They may have had a strong associations with death[2][3]: paled skin; dark hair; connections with the earth; their role in mythology. They followed animistic traditions, showing similarities to such concepts of the dead. They were similar to others from the 'Vættir' family, such as Elves.[2]

he first bomb was exploded in a test at Alamogordo, New Mexico, on July 16, 1945. See also Manhattan Project. Two more bombs had been built, and the possibility arose of using them to convince the Japanese to surrender. President Harry S. Truman decided to allow the bombs to be dropped. For maximum psychological impact, they were used in quick succession, one over Hiroshima on August 6, the other over Nagasaki on August 9. These cities had not previously been bombed, and thus the bombs’ damage could be accurately assessed. U.S. estimates put the number killed or missing as a result of the bomb in Hiroshima at 60,000 to 70,000 and in Nagasaki at 40,000.

Although the human cost of the war was tremendous, casualty figures cannot always be obtained and often vary widely. Most experts estimate the military and civilian losses of Allied forces at 44 million and those of the Axis at 11 million. The total number of civilian losses includes the 5.6 million to 5.9 million Jews who were killed in the Holocaust. Of all the nations that participated in World War II, the human cost of the war fell heaviest on the USSR, for which the official total, military and civilian, is given as more than 20 million killed. The United States, which had no significant civilian losses, sustained more than 400,000 deaths.

n the final days of the war, at the fall of Berlin in 1945, Hitler married his long-time mistress Eva Braun. Facing capture by Soviet forces less than two days later, the two committed suicide.[4]
