What color is the brightest star?

Sirius is 8.6 light-years from Earth, and its scientific designation is Alpha Canis Majoris. It also goes by the names Canicula, Dog Star and Aschere. The next-brightest star, Canopus, is 74 light-years from Earth and shares the same classification and color as Sirius. The third-brightest star is called Rigil Kentaurus, also known as Alpha Centauri. With a G classification, Rigil Kentaurus appears as yellowish-white to the human eye.

Which historical figure is considered to be the father of biology?

Aristotle made note of many things that are now considered basic in biology. He was the first to observe that animals are specifically adapted to their environment. He also elaborated upon the concept of parsimony, the idea that animals never spend unnecessary energy and they only retain organs and structures that are useful to them. Aristotle applied his systematic approach of scientific study to many other fields, including physics and linguistics. Indeed, he is often cited as the father of science in general.

What is an acronym for remembering the planets?

The first letter of each word represents a planet in order, moving away from the sun. Mercury is closest to the sun, then come Venus, Earth, Mars, Jupiter, Uranus, Saturn, Neptune and finally the dwarf-planet Pluto. There are many variations of acronyms used to remember the planets, and children and teachers often make up their own.

What are some of the human effects on the taiga biome?

Hydroelectric dams alter the hydrology and water flow characteristics of aquatic ecosystems including streams, rivers and wetlands. The surrounding terrestrial ecosystems suffer harm as well. The timber industry in Canada clears innumerable acres of forest habitat each year. This places pressure on wild animals, which are forced to cope with reduced ranges and access to resources. Natural gas and petroleum extraction techniques also cause the destruction of forests. Alberta’s energy sector alone clears about 470 square kilometers of forest each year.\nThe taiga biome is very large and stretc..

How do you calculate CFH from BTU?

Identify the BTU numberFind the British Thermal Unit number that needs to be converted. Utilize the conversion equationCalculate the conversion by placing the BTU number in the conversion equation. The equation explains that one cubic foot per hour, or CFH, is equal to 1,000 BTU of natural gas or 2,500 BTU of liquid propane when exposed to the environment. Multiply the BTU number by the correct factorMultiply the BTU number that needs to be converted by the correct factor from the equation, depending on whether natural gas or liquid propane is being used.

How many miles deep is the earth's crust?

The earth's crust is composed of vast pieces of rock called plates, which effectively float on the hotter, denser layer called the mantle. Temperatures at the deepest part of the crust can reach 1,600 degrees Fahrenheit, and it is at this depth that a layer called the Mohorovicic discontinuity, sometimes called the Moho, is found. This layer separates the crust from the hotter, softer mantle.

When is the constellation Cygnus visible?

Cygnus was one of the 48 constellations first listed by the Greek astronomer Ptolemy. Its prominent asterism (recognizable pattern of stars visible from earth) gives it the form of a swan or cross. According to myth, the musician and poet Orpheus, after being killed by the maenads, was changed into a swan and placed in the sky next to his lyre, the constellation Lyra.

What are examples of metalloids?

Scientists agree that "metalloid" is a vague term, and even an element usually thought of as a true metal, such as aluminum, might be classified as a metalloid.\nOften metalloids have the luster of metal but are brittle in a way that real metals are not. They can generally be alloyed with metals and are useful as semiconductors and flame retardants. They're also used in fireworks, signal lights and flares.\nSome metalloids, taken in trace amounts, support good health. These include silicon, boron, and even arsenic in incredibly tiny amounts, though arsenic in any appreciable quantity is t..

What is a break in the Earth's crust called?

There are various types of faults, including a normal fault, reverse fault, strike-slip fault and transform fault. Normal faults occur when rocks above the fault plane move down to the rocks below the plane and cause rocks to pull apart, while reverse faults are the result of rocks moving upward to the rocks below the plane. Strike-slip faults are the result of shearing stress that causes rocks to slide parallel to the fault line, and transform faults occur when a crack occurs in part of two tectonic plates' boundary.

Are volcanoes mountains?

Most famous volcanoes are in conical mountains, which look like mountains with craters instead of peaks. Well-known volcanoes with this shape include Mount St. Helens, Mount Vesuvius and Mount Fuji. Underwater volcanoes are vents on the surface of the ocean that can develop into pillar- or mountain-like shapes. Other types of volcano shapes include shield volcanoes, lava domes and subglacial volcanoes.
