How do you start recycling cans and bottles?

Recycling aluminum cans comes with a small return per pound. Rates vary per state or center. Contact local recycling centers to determine a price and whether the center has an existing promotion, coupon or returning customer bonus program. Some states pay for other recycled materials, but many do not, so research your state's policies and restrictions.\nSome states have "bottle bills" in which a person pays a deposit amount when they purchase the container. Once they empty the container, they can return it to a retail store or a redemption center and reclaim the deposit amount. Some of th..

How old is the Earth?

The earth and the rest of the solar system are believed to have formed out of a cloud of dust and gas called a nebula. Over time, this cloud condensed and became a flat, rotating cloud with a dense central region. As more time passed, the central region contracted into a protosun surrounded by rings of gas and dust that collided to form planetesimals. Eventually, the sun ignited, and the solar system was born. Earth was the third planet out.

What is a chain of islands called?

Island arcs, or chains of oceanic islands, form over intensely hot regions within the Earth. Islands are formed when hot spots rise just beneath the surface and cause the Earth's crust to shift. The arc of an island chain indicates the pattern in which the crust shifted. One of the best known archipelagos are the Hawaiian Islands, which were created by movements in the Pacific tectonic plate.

How many milliliters are in a half gallon?

One cup equals 236.6 milliliters, which is 0.2366 liters. A milliliter is defined as 1 cubic centimeter. Milliliters are based upon the cubic meter of volume for international units, otherwise known as the metric system. Milliliters are measured in graduated cylinders made of plastic or glass.\nGallons equal 231 cubic inches in the United States and 277.42 cubic inches in Great Britain. Commodities measured in gallons include milk, gasoline, juice and bottled water.

What is the biggest star in the universe?

There may be many stars significantly larger in the Milky Way that are hidden from view and as yet unobserved by scientists. Latest theories suggest the largest possible size for any star in the universe is 2,600 times greater than the size of the sun.

What is the definition of land conservation?

Land conservation through easements and trusts allows landowners to preserve sections of their land for conservation purposes. Certain rights are given up with a legal easement or trust, such as the right to develop the property later. Future owners, or heirs to the trust, are bound by the same legalities. Easements and trusts donated for conservation can have tax-deduction benefits in the United States.\nReducing erosion is another method to conserve land. Contour buffers between crops, contour farming on slopes and cover crops all help preserve agricultural land. Buffers work for gradual slo..

What is the function of the cribriform plate?

The cribriform plate is a component of the ethmoid bone that separates the nasal cavity from the brain, with the roofs of the eye sockets situated at the sides of the plate. The cribriform plate has a thin, narrow, sieve-like structure pierced with small holes. Several divisions of the olfactory nerve run through these tiny perforations. The nerve fibers come from the mucus membrane of the nose and provide humans with the sense of smell.

Why are alloys important?

An alloy is a metal composed of more than one element and may have properties different from those of its parent elements. While some alloys such as electrum (a mix of silver and gold) and meteoric iron-nickel are found in nature, humans have been creating alloys for their own uses for more than 4,500 years. An early example of a man-made alloy is bronze, which is made from copper and tin but is harder and stronger than either and can be used to make weapons and tools. Another example is steel, a widely used alloy of iron and carbon that is harder and tougher than pure iron.\nProperties of a m..

Which muscles are used during a baseball swing?

Because the key to a good baseball swing is the speed of the bat head through the hitting zone, conditioning coach Bob Alejo recommends resistance-based training. He says that exercises that rely strictly on body weight resistance are inadequate for developing maximum bat speed. For upper abdominal muscles, Alejo suggests adding weights held at arms length while laying on the back and completing three sets of 10 to 20 repetitions. For lower abdominals, the preferred exercise is hanging leg raises with weights attached to the ankles.\nThe second area to work on is leg strength. The strength of ..

What family does boron belong to?

Another term for the earth metal family is group 13. All of the elements in the group have three valence electrons and have properties that place them between metals and nonmetals. Officially, boron is classified as a semi-metal, and the rest of the group are classified as metals. Ununtrium is a man-made radioactive element that has not been widely studied. Scientists classify it in the boron group because of its close relationship with thallium.
