Droughts occur when evaporation and transpiration rates consistently exceed precipitation over an extended period of time. This prolonged imbalance results in water shortages, crop damage, and reduced streamflow. The primary causes of drought are insufficient rainfall or inadequate snowpack. There

What Causes a Rainbow?, The formation of a rainbow begins with the refraction of sunlight as it enters a raindrop. Refraction is the change in direction of a wave (in this case of lightwaves) as it passes from one medium to another caused by its change in speed. Because light travels at different

Volcanic eruptions are among the most stunning phenomena in the natural world. Volcanoes erupt because of the way heat moves beneath Earth’s surface. Heat is conveyed from the planet’s interior to its surface largely by convection—the transfer of heat by movement of a heated fluid. In this case,

The main contributors to acid rain are sulfur dioxide (SO2) and nitrogen oxides (NOx; the combination of NO and NO2), which are released into the air primarily through the combustion of such fossil fuels as coal, oil, and natural gas. These pollutants are emitted by power plants, vehicles, and

Allergic reactions are caused by substances known as allergens. These substances can be found in a variety of sources such as pollen, mold spores, dust, animal dander, and certain foods. These substances induce the hypersensitive state of allergy and stimulate the formation of reaginic antibodies,

We all know what money is. It’s what we use to buy and sell goods and services and, from a savings and investing standpoint, it’s how we keep score of (i.e., place a value on) the assets we own. But how much does money cost? That might sound like a strange question, because we typically associate

An eclipse happens when one astronomical body blocks light from or to another. In a lunar eclipse, the Moon moves into the shadow of Earth cast by the Sun. When the Moon passes through the outer part of Earth’s shadow—the penumbra, where the light of the Sun is only partly extinguished—the Moon

While it is commonly thought that mirages result from people’s imagination, the phenomenon is actually caused by mere optics. Mirages are optical illusions that appear when light rays bend, or refract, through layers of air with varying temperature and density. Light refraction occurs due to

Sinkholes are depressions that form when the underlying limestone bedrock is eroded or dissolved by groundwater. Water, especially when it is slightly acidic, can dissolve soluble rocks like limestone over time (see also acid rain). The wearing away of limestone in contact with the water creates

Soil erosion, like rock erosion, is caused by the movement of water and wind, and glaciers. Since soil (whether loose of compact) is less resistant to these forces, soil erosion tends to occur more rapidly than rock erosion. This article will consider the causes of soil erosion that humans are more

The auroras—the aurora borealis (or northern lights) in the Northern Hemisphere, and the aurora australis (the southern lights) in the Southern Hemisphere—are brilliant natural spectacles that can be seen in the evening sky especially at higher latitudes. Unlike other phenomena of the night sky,

Thunder is caused by the rapid expansion of air heated by a lightning discharge. When lightning strikes, it heats the air in its path to temperatures as high as 30,000 °C (54,000 °F). This intense heat causes the air to expand rapidly, creating a shock wave that travels outward. As this shock wave

The main cause of tides in the ocean are the gravitational forces exerted by the Moon and the Sun on Earth. When it comes to tide generation, the Moon’s gravitational pull is about 2.2 times stronger than that of the Sun . The Moon’s gravitational field varies across Earth’s surface because of

As natural disasters go, tsunamis are among the worst in terms of overall destruction and loss of life. They rival earthquakes in their ability to suddenly devastate a wide area. In recent years massive tsunamis have caused extensive damage in northern Sumatra and Thailand, parts of Japan’s Honshu

Want to know how hot a fire is burning? The color of its flames can help. When something burns, it is undergoing combustion. Combustion is a chemical reaction that, typically, turns oxygen and fuel into heat and light in the form of a flame, which can range in color depending on how efficiently

Not black, despite what the night sky may suggest. The vast expanse of the universe that separates stars and galaxies—space as we know it—looks black to the human eye, as it is mostly empty. The stars and galaxies that produce light are extremely far apart, and the light that reaches the Earth is

Most people don’t spend time thinking about the smallest units of data, bits and bytes. But when it comes to data transfer or storage, most of us are concerned with the megabytes, gigabytes, or even terabytes. As data capacity increases, what size hard drive should you be looking for next? Data

When you apply for loans and other financial products, you’ll probably agree to a credit check. The bank or lender wants to know that you can handle debt and that you have a solid history of making payments. It uses your credit score to determine whether you’re a good credit risk. If you have a

Ducks are omnivorous birds that feed on both plants and animals. Their varied diet may include aquatic vegetation, insects, seeds, and sometimes even small animals. What they eat largely depends on their species, habitat, and the time of year. Most ducks feed in or near water. Dabbling ducks, such

Easter is the principal festival of the Christian church, a celebration of the Resurrection of Jesus Christ on the third day after his Crucifixion. So where do the colored eggs fit in? The egg was a widely used premodern and pre-Christian symbol of fertility and restoration. European “Pagans” (a

Frogs have a diverse diet that primarily consists of insects and other small invertebrates, though some species also consume larger prey. As insectivores, most frogs feed on a wide array of bugs such as flies, mosquitoes, and beetles, using their long, sticky tongues to snatch fast-moving prey with

Giraffes, as browsers, primarily feed on new, tender shoots and leaves of trees, with a particular fondness for the thorny acacia tree. They use their long necks to browse foliage that is as high as 6 meters (20 feet) off the ground. This ability to reach tall branches gives them access to food

Kangaroos are herbivores, which means they eat only plant-based foods. Their diet mainly includes grass and other types of vegetation. Larger species, such as red and gray kangaroos, are grazers. They feed mostly on grass, much like cattle and sheep, which eat large amounts of grass in open areas.

Rabbits are herbivores and primarily consume a diet rich in plant material, such as grasses and forbs (herbs other than grasses). Their diet is rich in cellulose, a complex carbohydrate that is a key component of plant cell walls. Cellulose is difficult to digest, but rabbits have adapted to

Squirrels’ diets vary based on their species and habitat. The most commonly recognized squirrel, the bushy-tailed tree squirrel, has a diet that primarily consists of nuts and fruits. Squirrels are equipped with strong, chisel-like incisors and powerful jaws, which are essential for gnawing open
