Is Uranus hot or cold?

The extreme weather on Uranus is largely due to the planet's sharp axial tilt of almost 98 degrees Fahrenheit. In comparison, Earth only has a tilt of 23.5 degrees. Earth has 10 percent more gravity than Uranus. Over 80 percent of the atmospheric composition of Uranus is made up of hydrogen, while helium and methane make up the rest. The 2.3 percent composition of methane is what gives Uranus a bluish-green color.

What are some different sheet metal gauges?

The gauge, also spelled gage, is a set standard for the thickness and weight of sheet metals. Gauges differ between iron and iron-based metals like steel and other metals like aluminum or brass. A sheet of steel is slightly thicker than a sheet of aluminum of the same gauge, while the same gauge of zinc is much thinner than either. Zinc sheet metal of a gauge of three is only 0.006 inches (0.15 millimeter) thick. The lowest gauges, zero to 0000000, are only used for heavy steel sheets and iron plates between 0.31 to 0.50 inch thick, while the highest standard gauge of 38 refers to steel that i..

Does NASA track solar flare activity?

It is important to monitor solar flares and other solar activity because they may impact Earth. A solar flare can impact Earth if the event happens on the side of the sun facing towards the planet. Solar flares can alter Earth's upper atmosphere temporarily, which in turn can cause disruption with signal transmissions and wireless communication. For example, it can cause problems for GPS satellites and affect television and radio broadcasts. Solar flares can also cause a power grid to fail; this occurred in 1989 when solar flares caused disruptions and a major blackout in Quebec.

What plants live in grasslands?

Average annual rainfall can support an occasional tree, but drought and grassland fires that sweep through every one to five years prevent the growth of large forests. The tallest prairie grass, big bluestem, or turkey feet, can reach 11 feet tall with a root system 7 feet long. It grows where the climate is wet, while shorter varieties of grass dominate drier areas with hotter summers and colder winters. The deep root systems fortify the plants against strong winds and help keep the soil in place. Grassland plants die back in winter but are kept alive by the robust underground support system ..

Why isn't the atomic mass usually a whole number?

On the periodic table, students can find the atomic mass written below the element's name. The number written above the element is the atomic number, which is the number of protons of a given element. For example, lithium has an atomic mass of 6.941 and an atomic number of 3.

What can I substitute for kaffir lime leaves?

To zest a lime as a substitute, wash and dry the lime. Hold the lime still, and run a zest grater over the lime. Only take the green part of lime, as the white pith can be bitter. Scrape the zest into a measuring spoon to measure the amount. A tablespoon of lime zest is usually enough if the recipe calls for six lime leaves.

What is a mid-ocean ridge?

Mid-ocean ridges are formed when the ocean floor is uplifted and two tectonic plates meet at the same boundary. Magma forms and causes a mountain range to rise up from the ocean floor. All of the mid-ocean ridges in the world are connected and form one single global mid-oceanic ridge system that can be found in every ocean on Earth. This means that the mid-ocean ridge is the longest mountain range on Earth. It has a total length of approximately 60,0000 kilometers.

What are the day and night temperatures on Uranus?

Uranus is the coldest planet in this solar system, even though it is not the furthest planet from the sun. The planet is a gaseous planet, made up of mostly hydrogen, helium and methane. The blue-green appearance of the planet is due to the methane in its atmosphere. The planet's internal temperatures may reach 8,540 degrees Fahrenheit. The length of a year is equivalent to 84.01 Earth years.

What does a biologist do?

Research biologists study different groups of living organisms around the world. These types of biologists use state-of-the-art research techniques and tools to examine species such as micro-organisms, mammals, reptiles and amphibians in their natural habitats. Therefore, research biologists generally perform their work in exotic locations across the globe.\nHealth care biologists include physicians, veterinarians, nurses and dentists. These types of biologists prevent the spread of infectious and deadly diseases and formulate ways to enhance the health and well-being of their patients.\nEnvir..

Which elements tend to form covalent bonds?

The purest form of a covalent bond exists in diatomic gases. Hydrogen, oxygen, nitrogen and the halogens all form these types of bonds. By sharing an electron they satisfy the octet rule for both atoms. Because the atoms have the same electronegativity, the shared electron has the same attraction to both.\nThe carbon-hydrogen bond organic materials require a covalent bond. These two elements form long chains that sometimes branch and have functional groups bonded to the chain. Breaking the covalent bond requires energy. In contrast, many ionic compounds readily dissociate when dissolved in wat..
