Rain is liquid precipitation: water falling from the sky.
Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one. As this continues to happen, the droplet gets heavier and heavier. When the water droplet becomes too heavy to continue floating around in the cloud, it falls to the ground.
Human life depends on rain. Rain is the source of freshwater for many cultures where rivers, lakes, or aquifers are not easily accessible. Rain makes modern life possible by providing water for agriculture, industry, hygiene, and electrical energy. Governments, groups, and individuals collect rain for personal and public use.
Raindrops condense around microscopic pieces of material called cloud condensation nuclei (CCN). CCN can be particles of dust, salt, smoke, or pollution. Brightly colored CCN, such as red dust or green algae, can cause colored rain. Because CCN are so tiny, however, color is rarely visible.
When rain forms around certain types of pollutants, such as sulfur dioxide and nitrogen oxide, the CCN react with water to make the rain acidic. This is called acid rain. Acid can harm plants, aquatic animals like fish and frogs, and the soil. Sulfur dioxide and nitrogen oxide can be released into the atmosphere naturally, such as through a volcanic eruption. These pollutants can also be released by human activity, such as the burning of fossil fuels.
Burning fossil fuels can influence rain patterns. In urban areas, where many vehicles are on the road at once, rainfall is more likely during the weekend than during the week. This is because during the week, millions of cars release exhaust into the atmosphere, creating billions of CCN in the clouds. By the end of the week, clouds are much more likely to be saturated with moisture and CCN.
Scientists have developed a process called cloud seeding to "plant" CCNs in clouds to cause rain. Cloud seeding would reduce drought, although there is very little evidence that it works yet.
Although most people think raindrops look like teardrops, they actually look more like chocolate chip cookies. Like raw balls of dough dropped on a cookie sheet, the smallest raindrops, up to 1 millimeter in diameter, are actually spherical. At 2 millimeters raindrops start to flatten, because of the air pressure pushing up on them as they fall to Earth. This effect is increased at 3 millimeters, and depressions form on the bottom of the drops as the air pushes up on the drops harder. At 4 millimeters raindrops actually distort into a shape that looks like a parachute. When they get to be about 4.5 millimeters in diameter, raindrops are so big that they break apart into two or more separate drops.
Raindrops measure 0.5 millimeter (.02 inches) in diameter or larger. Drizzle, which is smaller than rain, consists of drops smaller than 0.5 millimeter. Most of Earth's precipitation falls as rain.
Raindrops often begin as snowflakes, but melt as they fall through the atmosphere. Snow forms in the same way rain does, but in colder conditions.
Rain falls at different rates in different parts of the world. Dry desert regions can get less than a centimeter (0.4 inches) of rain every year, while tropical rain forests receive more than a meter (3.2 feet). The world record for the most rain in a single year was recorded in Cherrapunji, India, in 1861, when 2,296 centimeters (905 inches) of rain fell.

snake
snake, (suborder Serpentes), also called serpent, any of more than 3,400 species of reptiles distinguished by their limbless condition and greatly elongated body and tail. Classified with lizards in the order Squamata, snakes represent a lizard that, over the course of evolution, has undergone structural reduction, simplification, and loss as well as specialization. All snakes lack external limbs, but not all legless reptiles are snakes. Certain burrowing lizards may have only front or hind limbs or be completely legless. Unlike lizards, snakes lack movable eyelids, which results in a continuous and often disconcerting stare. Snakes also lack external ear openings. Internally, they have lost the urinary bladder. The visceral organs are elongated, with reduction of the left member in relation to the right; the left lung is greatly reduced or even lost entirely. However, snakes possess increased numbers of vertebrae and have developed two novelties among vertebrates: a tracheal lung in the neck region and a venom-conducting system for subduing prey.

Snakes are thought to have evolved from terrestrial lizards as early as the Middle Jurassic Epoch (174.1 million to 163.5 million years ago). The oldest known fossil snake, Eophis underwoodi, was a small snake that lived in southern England about 167 million years ago.
Snakes and humans
Snakes are misunderstood and often maligned, primarily out of ignorance about their true nature and position in the natural world. All snakes are predators, but venomous snakes (that is, biting snakes that use their fangs to inject toxins into their victims) have given an inaccurate reputation to the entire group, as most people cannot tell the dangerous from the harmless. Only a small percentage (fewer than 300 species) are venomous, and of those only about half are capable of inflicting a lethal bite. Although snakebite mortality worldwide is estimated at 80,000–140,000 people per year, the majority of deaths occur in Southeast Asia, principally because of poor medical treatment, malnutrition of victims, and a large number of venomous species. Although there are about 8,000 venomous snakebites per year in the United States, the average number of annual fatalities is less than 10 or so per year—fewer than are attributed to bee stings and lightning strikes. In Mexico, 10 times as many people die annually from bee stings as from snakebites.

Snakes can control the amount of venom they inject and may bite aggressively for food or defensively for protection. Snakes have a limited amount of venom available at any given time and do not want to waste it on nonprey organisms. As a result, about 40 percent of bites suffered by humans are defensive in nature and “dry” (without envenomation). Statistics show that the vast majority of snakebites occur while either catching and handling captive snakes or trying to molest or kill wild ones. In either case, the snake is only defending itself. Rattlesnakes, for example, are venomous, and large ones are quite dangerous owing to the amount of venom they can inject. However, most are shy and retreating, and none will attack a person unmolested. When approached or molested, they will coil up and rattle as a warning to be left alone, striking only as a last resort. Most cases of reputed snake attack are based upon encroachment by a person into the snake’s territory, which makes it feel trapped or cornered, or provocation of a snake during the breeding season. Even in these scenarios, only two snakes have a reputation as dangerous aggressors: the black mamba (Dendroaspis polylepis) of Africa and the king cobra (Ophiophagus hannah) of Southeast Asia. Nevertheless, snakes are inoffensive under the vast majority of circumstances. People are rarely indifferent about them, generally exhibiting emotions that range from religious awe and superstitious dread to repulsion and uncontrollable fear. It is interesting to note that, although most people profess to fear or hate snakes, one of the most visited areas of any zoo is the snake house—proof that snakes are mysterious and fascinating, even if they are loathed. Given their exquisite colours, patterns, and graceful movements as they crawl, swim, or climb, some snakes can be considered among the most beautiful animals.
In common parlance, venomous snakes are often referred to as “poisonous snakes.” This phrase is not technically correct, because the term “poisonous” only applies to organisms that unload their toxins when another organism consumes them. Very few snakes are truly poisonous. One of the most common, yet harmless, poisonous snakes in North America is the garter snake (Thamnophis), whose body has the ability to absorb and store the toxins of the newts, salamanders, and other poisonous prey it eats.

Nearly every culture since prehistoric times (including various present-day cultures) has worshipped, revered, or feared snakes. Serpent worship is one of the earliest forms of veneration, with some carvings dating to 10,000 BCE. Although Satan is depicted as a serpent in the biblical account of the Creation, snakes are revered by most societies. A vast global compendium of superstitions and mythologies about snakes has sprung up. Many stem from the snakes’ biological peculiarities: their ability to shed their skin is associated with immortality; their ever-open eyes represent omniscience; their propensity for sudden appearance and disappearance allies snakes with magic and ghosts; a phallic resemblance embodies procreative powers; and the ability to kill with a single bite engenders fear of any snakelike creature.

The hides of six snake species (especially pythonss and wart snakes) are commonly bought and sold in the skin trade. The number of rattlesnakes used for their skins is minor in comparison. Hundreds of thousands of live snakes are collected for sale in the international pet trade. Nearly 100,000 ball pythons and 30,000 boa constrictors are imported annually into the United States. The removal of such enormous numbers from the wild threatens the survival of these species, and many snake populations are in decline as a result of capture and habitat destruction. The release of nonnative pet snakes into the wild has also led to the introduction of several invasive species, including the Burmese pythons that have devastated small mammal populations in the Florida Everglades.

Most snakes do not spend much of their time doing anything but resting. A snake’s primary activity is concerned with either thermoregulation or finding live food, which often involves passive waiting rather than active searching. The thermoregulation problem varies with latitude and altitude. The actions and reactions of a snake in temperate North America are distinct from those of one living in the American tropical lowlands but are similar to those of another living at higher altitudes in the Andes of Ecuador. No matter where they live, snakes are subjected to pressures from the living (biotic) parts of the environment as well as from the physical, nonliving (abiotic) parts. But the amount or degree of challenge to the snake from different segments of the environment changes drastically depending upon the region it inhabits. An individual living in the hot, humid tropics of Africa, with comparatively constant temperatures close to optimum throughout the year and ample moisture from both rainfall and the surroundings, faces environmental problems that are overwhelmingly biotic, involving competition with other members of its own species for food, the challenge from other species of snakes and perhaps other vertebrates for possession of the ecological niche, and constant pressure of the predators that find it a tasty morsel. On the other hand, the common adder, or European viper (Vipera berus), living north of the Arctic Circle in Europe, is the only snake present in the area and lives practically unchallenged in its niche. However, its survival is challenged continually by its physical environment, and death from overheating, freezing, or dehydration is a repetitive threat. These differences between animals from different parts of the world are reflected in their life histories, and it is neither possible nor legitimate to speak of the “life history of the snake” unless one speaks of only a single region or species.
