What are some characteristics of Saturn?

Electricity that runs through this metallic hydrogen is thought to give Saturn its relatively weak magnetic field.\nSaturn's mass is 95.16 times that of the Earth. It is 9.58 astronomical units, or AU from the sun. One AU is the distance the Earth is from the sun, or about 93 million miles. The surface temperature of Saturn is 218 degrees Fahrenheit.\nScientists also believe that the core of Saturn is made largely of iron and nickel and is several times the size of Earth. The saying that Saturn can float in a bathtub big enough to hold it is true, for it is less dense that water. Saturn&a..

Why is the water cycle important?

The water cycle is an important process that recycles water and nutrients. In doing so, it brings freshwater to people, animals and plants all around the world. The water cycle begins with the ocean, lakes, ponds and other bodies of water on earth. Water evaporates from these bodies of water, and as the evaporated water lifts into the sky, it is cooled rapidly and condenses to form clouds. These clouds act as storage compartments for water. As they become filled with water, precipitation occurs. Clouds travel all around the world by wind currents and can bring precipitation to every part of th..

Is sulfur a metal or non-metal?

Sulfur is a brittle substance that is insoluble in water. Its atomic weight is 32.065 grams per mole, and its density is 2.067 grams per cubic centimeter. There are four isotopes of sulfur.In nature, sulfur is found in conjunction with different minerals, including gypsum, pyrite and barite. The most common application of sulfur is in the production of sulfuric acid. There are different compounds formed from sulfur, such as sulfur dioxide and hydrogen sulfide.

What does a home need to have to be considered a green home?

For a home to be "green," it must be designed to have as little impact on the environment as possible. When selecting a site for a green home, experts recommend choosing an area that has already been developed and building the smallest house that meets your needs. Selecting a site near public transportation will further reduce energy use by allowing the occupants to take advantage of mass travel.\nWhen designing the home, it should be orientated to take advantage of natural heating and cooling from the sun and wind. Landscaping, like a large shade tree, can also be used to provide extra insula..

Why was the periodic table invented?

Mendeleev devoted much of his time in the late 1860s and early 1870s to identifying and comparing elements. He frequently discovered new elements while performing experiments, but had no way of keeping track of his findings. Consequently, he began jotting down new elements on paper, but quickly realized that he needed a way to sort and organize them for easy future reference. Mendeleev began loosely organizing a chart, which grouped elements according to their atomic weights. As he plotted elements in horizontal rows on his chart, Mendeleev noticed a distinct pattern begin to appear, but only ..
