What is the surface of Mars like?

Mars has quite a few geological surfaces that make it unique. Some features on Mars are visible by the naked eye while others are apparent only through telescopes, space ships and other astronomical equipment. The shield volcanoes on the surface of Mars are virtually extinct, although they are still prominent features. These volcanoes, true to their name, resemble large shields in appearance. They have wide and relatively flat bases that form the shape of large rectangles and squares. Shield volcanoes may cover large distances, and have bases that span several hundred miles. These volcanoes ma..

How do you find the date for the next new moon?

The Moon orbits the earth every 27.3 days, but the lunar phase cycle from one new moon to the next new moon is 29.5 days. This 2.2-day remainder is a result of the fact that the Earth travels 45 million miles around the Sun in its own orbit during the time the Moon completes a single orbit around the Earth and subsequently has to catch up on the additional distance traveled.\nDuring each new moon phase, the Moon travels close enough to the sun that no part of its surface visible to Earth is illuminated by the sun's light. This is in contrast to the full moon phase, wherein the totality of..

What is the scientific name of the fortune plant?

The fortune plant is also commonly called ribbon dracaena, Chinese water bamboo, Belgian evergreen, ribbon plant, friendship bamboo, Sander's dracaena, Goddess of Mercy and curly bamboo. While true bamboos rival trees in height, the fortune plant grows to only 3 to 5 feet tall, making it a popular houseplant. Fortune plants require little care and grow in soil, sand or water. They are often placed in water or fine gravel for decorative displays.

Where can you find lithium?

Lithium is an element and it does not provide vital biological functions for humans. Doctors use it as a mood stabilizer in the lithium ion Li+ form. Lithium salts may also be beneficial in stabilizing the mood. In the industrial world, lithium is a common component in the manufacture of ceramics, glass and aluminum.

What are the dimensions of a 55-gallon drum?

Other common drum sizes include 14, 15, 20 and 53 gallons. These drums are ideal for use with food products, hazardous waste and other solid materials with easy handling, and most are equipped with a lever-locking closure ring for safety. While traditional 55-gallon drums are made of steel, plastic drums have become increasingly common as a lightweight, yet durable alternative. Plastic drums are also UV-protected and rust-proof, offering an extended life compared to a steel drum.

What is the difference between B.C. and A.D. in a timeline?

This system does not contain the year zero. It was developed in 525 A.D., which, because of this feature, is considered the sixth century. It was not used extensively until after 800 A.D. Dionysius Exiguus, an eastern European or Russian monk, created the system. He wished to replace the old Diocletian 247 system, because the Emperor Diocletian promoted the persecution of Christians.\nDionysius based the system on his supposition that Jesus was born 753 years after the founding of Rome, which turned out to be incorrect. However, scholars do not know how Dionysius calculated this date.\nWhen th..

How was the universe created?

Scientists believe that about 13 billion years ago all of the energy, space, time and matter in what eventually became the universe were compressed into a singularity, a tiny point. Some force caused this point to expand, and it has continued expanding ever since.\nWithin a nanosecond of the Big Bang, the universe was trillions of degrees Kelvin in temperature and hundreds of millions of miles across. The universe was too hot for atoms to form, but it was a soup of photons and particles with various types of properties. Some of these particles no longer exist today.\nAs the universe cooled, qu..

What does OIL RIG mean in chemistry?

Oxidation and reduction always occur together in one of these reactions, since what is lost by one molecule is gained by the other. For instance, when zinc is placed into hydrochloric acid, the zinc oxidizes and loses electrons. These electrons reduce the hydrogen atoms, allowing them to bond and form dihydrogen gas while the zinc bonds with the free chlorine to create zinc chloride.

What are the sources of chlorofluorocarbons?

At the point of emission, CFCs are stable, nonflammable, nontoxic, odorless and colorless. However, they start breaking apart and releasing chlorine atoms the moment they reach the stratosphere. The highly reactive rouge chlorine atoms break down the ozone layer, which is responsible for preventing the harmful ultraviolet radiation of the sun from reaching the earth's surface.Due to their known destructive properties, the production of CFCs was banned in 1995. They have been replaced by ozone-safe Hydrofluorocarbons.

How is a volcano formed?

From the magma reservoir, the molten rock is pushed up through cracks in the solid rock above it by the force of gas pressure that builds up, as well as buoyancy because the molten material is lighter than the solid formations around it. As the material exits the vents at the surface of the Earth and accumulates in sufficient quantities, the force of gravity causes some of the material to fall down the sides toward ground level, eventually creating the conical shape of the classic volcano.\nWhile this process typically takes hundreds or thousands of years, some volcanic mountains can be formed..
