Still, hydrogen is the third most abundant element on the Earth's surface. Most of the Earth's hydrogen is in the form of chemical compounds such as hydrocarbons and water.[13] Hydrogen gas is produced by some bacteria and algae and is a natural component of flatus.
Compared to a similarly-sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (it averages about 90 cm (35 in) tall) and so it appears more streamlined. An cheetah weighs about 95-250 pounds.
Baby cheetahs, called cubs, are very small when they are born, weighing 5 to10 ounces (150 to 300 grams), according to the San Diego Zoo. As the cubs grow, the mother teaches them how to hunt and other essentials. Cubs will stay with their mothers for one and a half to two years. Even under a mother's watch, 90 percent of cubs still die before they are three months old, according to the Smithsonian. Lions and hyenas often eat the young cheetahs. If they do make it to adulthood, the cats only live for around 10 to 12 years.
