Mountains and freshwater
Mountains and freshwater
Mountains are often called nature's water towers. They intercept air circulating around the globe and force it upwards where it condenses into clouds, which provide rain and snow.
Mountains also store water in various ways, including the formation of snow and ice which is later released as melt-off during warmer periods (often those with the lowest rainfall).
It is no surprise then that in semi-arid and arid regions, over 70 to 90 percent of river flows come from mountains. But even in temperate areas, 30 to 60 percent of freshwater can come from highland watersheds. In the Rhine basin, for example, the Alps provide 31 percent of annual flows — in summer more than 50 percent — even though they make up just 11 percent of the basin's land area.
In fact, all the major rivers in the world — from the Rio Grande to the Nile — have their headwaters in mountains and one of every two people on the planet depends on mountain water in one way or another: for drinking, as a source of energy or income, for growing food.

Camels: Facts, Types & Pictures
Camels are mammals with long legs, a big-lipped snout and a humped back. There are two types of camels: dromedary camels, which have one hump, and Bactrian camels, which have two humps. Camels' humps consist of stored fat, which they can metabolize when food and water is scarce.
In addition to their humps, camels have other ways to adapt to their environment. They have a third, clear eyelid that protects their eyes from blowing sand. Two rows of long lashes also protect their eyes. Sand up the nose can be a problem, but not for camels. They can shut their nostrils during sand storms.
Humans have used camels as a means of transport for thousands of years. They can carry about 375 to 600 lbs. (170 to 270 kilograms) on their backs, according to National Geographic. This earned these beasts of burden a nickname, "ships of the desert." Domestic camels are often the main source of meat, milk and even leather or wool products.
Size
Most camels tower above humans. A Bactrian camel, according to the San Diego Zoo, grows to a shoulder height of 6 feet (1.8 meters) and a body length of 10 feet (3 m). They normally weigh 1,320 to 2,200 lbs. (600 to 1,000 kg) when they are fully grown

How beautiful nature ;
When you see a waterfall, an undisturbed meadow, or the glassy surface of a lake, it might be difficult to put the beauty into words. But, thanks to the efforts of natural poets and authors, we can use words like ethereal, verdant, and pristine to describe nature’s beauty. Keep reading to find the right word to describe your picturesque scene.
