What are the names of the earth's major plates?

The Theory of Plate Tectonics or Plate Tectonic Theory is a key body of knowledge for geologists trying to figure out "how the Earth works." It basically explains how and why formations such as volcanoes and mountains came about, as well as why earthquakes and tidal waves happen. The movement of the Earth's major plates throughout the planet's history is also responsible for the formation of the seven continents.Although the seven major plates of the Earth comprise most of the continental surface and the Pacific Ocean, the secondary plates cover the rest of the Earth's surface. ..

What are the results of human interaction on the tundra biome?

Ozone depletion is a larger threat to the poles than it is elsewhere because ozone collects in greater abundance around these areas. As a result, ultraviolet light faces less resistance and is more harmful to living organisms of the tundra. The melting of the tundra's permafrost can also lead to increased carbon emissions, as around 1/3 of the world's carbon resides there. If enough permafrost melts, significant amounts of greenhouse gases, such as carbon dioxide and methane, will escape. This in turn can accelerate the effects of global warming.\nThe defining characteristics of tund..

What are the characteristics of ionic bonds?

Ionic bonding produces two oppositely charged ions. When a metal and a non-metal atom form an ionic bond, the metal ion loses electrons and becomes a positively charged cation. Conversely, the non-metal atom gains electrons and becomes a negatively charged anion. Metals are good candidates for ionic bonding because they have few electrons in their outer shells. During ionic bonding, more than one electron can be accepted or donated.

What are fungi that absorb food from decaying organic matter?

Saprotrophic behavior is one of the four ways fungi obtain nutrients. Myorrhizal mushrooms form symbiotic relationships with other plants and animals. Usually, the relationship is mutualistic, meaning both organisms benefit. The mushroom weaves around the root cells of the plant or wraps around the roots themselves. The mushroom provides additional moisture and nutrients to the plant, and in turn, it gains access to sugars the plant produces. Endophytic fungi also form a mutualistic relationship with a host plant. However, they have their own category because, unlike myorrhizal mushrooms, they..

What is ferrous ammonium sulfate?

Ammonium iron(II) sulfate is obtained from iron, ammonia and sulfuric acid, while the hexahydrate is produced by a reaction between ammonium sulfate and ferrous sulfate. Commonly, a very pure form of Mohr's salt is used during the process of titration. It is also used in Fricke's dosemeter in order to measure large doses of gamma rays.

What are the benefits of volcanoes to humans?

The soil on and near volcanoes is rich in nutrients. This feature allows for strong plant growth, which aids the air quality and provides vegetation for people and animals. Certain elements found in volcanic ash and mineral deposits are also used in product manufacturing. Oregon State University Volcano World states that basalt and diabese deposits from volcanoes are often used in building production. Health and beauty manufacturers use pumice and volcanic ash in the development of soaps and household cleaners.\nA primary advantage of volcanoes is that their primary function is to vent hot ste..

What is equal to 2 quarts?

In order to convert quarts to cubic inches (a metric unit of measure for liquids), the number of quarts is multiplied by 57.7. Three quarts are equal to 173.1 cubic inches because this figure is the product of three multiplied by 57.7.To convert quarts to pints, the number of quarts is multiplied by two because there are 2 pints in a quart. Six quarts are equal to 12 pints (six multiplied by two).For quarts to be converted to gallons, the number of quarts is divided by four because there are 4 quarts in a gallon. If someone had 12 quarts, this equals 3 gallons (12 divided by four).

What is the name of the compound with the chemical formula C2H5OH?

Ethanol is a clear and colorless liquid commonly known as pure alcohol or beverage alcohol. It is volatile and flammable and can be produced through fermentation from various products that contain starch, such as corn, wheat and potatoes.\nEthanol is used as a solvent, fuel and preservative. It has bactericidal properties, so it can also be applied on the skin as a disinfectant. Industrially, ethanol is used as an intermediate in the production processes of other chemicals, including ethyl esters, acetic acid and ethyl halides.

Why do living things need nitrogen?

Free nitrogen comprises approximately 78 percent of the gas in the atmosphere. Before living things are able to use free nitrogen it must be fixed by bacteria. Nitrogen-fixing bacteria combine free nitrogen with other elements to form nitrogen compounds that can be absorbed through a plant's root system. Once a plant absorbs the nitrogen compound, it uses it to produce compounds that can be digested by animals. As a plant or animal decays, the remaining nitrogen in its body is returned to the nitrogen cycle.\nWhen an area has a nitrogen deficiency, a chemical fertilizer can be added to th..

What are the functions of human hair?

Hair acts as insulation for the body. When a person becomes cold, body hair stands up, creating added insulation and making body temperature rise. It also traps warm air next to the body, reducing a loss of heat.Hair found in the ears and around the eyes prevents foreign matter from entering the body. Eyebrows reduce the amount of light that enters the eyes. Hair is made of a strong protein called keratin. It is anchored to the skin by a hair follicle whose base is called the hair bulb. Blood vessels in the skin nourish hair bulbs and follicles, and each strand of hair is infused with hormones..
