The sun is around 875,000 miles across and weighs around 300,000 times more than Earth. In fact, the sun is so large, that 1,600 Saturns could fit inside. By comparison, the Earth is only around 25,000 miles around. Despite its enormity, the sun is not the largest star in the sky. There is a red giant called Betelgeuse, which is located in the Orion constellation, that scientists estimate is between 10 and 40 times the size of Earth's sun.
How did the lunar highlands form?

The lunar highlands formed when magma erupted from below the moon's surface into a lava lake. As the lava cooled, large rocks floated to the surface to form both of the highlands.\nThe highlands are made up of three different types of rock: Ferroan Anorthosite Suite, Mg-Suite and Alkali Suite. The first type is the most common and oldest rock found on the moon's highlands, dating back 4.5 billion years. This is the rock that crystallized and formed in the magma, then later floated on top during the creation of the primary crust of the highlands.\nOnce the lava forming the highlands c..
How does sleet form?

Sleet can only form under very specific weather conditions, which is why it is not as common as other forms of precipitation. It usually occurs during the winter when the proper conditions are most common. Sleet is different than freezing rain. Freezing rain also falls through a layer of cold air towards the ground. However, it freezes upon contact with the object and not in the air. Freezing rain lands as rain, but sleet lands as ice. Sleet is also different than hail. Similarly to sleet, hail is made of ice. Hail, however, freezes while in the clouds. Sleet freezes while it falls.\nAdditiona..

In the material domain, efforts are focused on the adoption of renewable sources of energy, with most sustainability programs targeting a shift away from the use of fossil fuels for energy because they are limited and non-sustainable. The economic domain focuses on the destructive nature of most economic activities and tries to create changes in the way measurements about economic activities are done, so as to minimize the negative impact of such activities on the environment. The life domain addresses the impact of human developments on the environment and advocates the protection of all form..
Does carbon graphite conduct electricity?

Graphite, a nonmetal, has a planar structure with honeycomb lattice layers. Apart from being soft, opaque and black, graphite is insoluble and has high boiling and melting points. The insides of pencils, batteries, arc-lamp electrodes and lubricants such as bicycle oil are made from graphite.\nAnother allotrope, or different form of carbon, is diamond. Diamond does not conduct electricity and is rather hard. Diamond can be changed to graphite if it is heated without oxygen.
What makes people float?

An individual's buoyancy depends greatly on her body type. Bone and muscle are more dense than water, while fat is less dense. Individuals with higher body fat ratios find floating easier, while those with less fat and more muscle float lower in the water. Lung capacity also plays a role, since the density of the air stored in the organs is much less than the surrounding water.

Heterotrophic representatives of Eubacteria absorb the nutrients from the environment while autotrophs, such as Cyanobacteria, obtain energy for life processes through photosynthesis. Autotrophic organisms classified as Archaebacteria are found in extreme environments, such as volcanos, hot springs or deep oceans, where they can’t use energy from the sun to produce food. Instead, they use energy from chemical reactions, according to National Geographic.

Oxidation of glucose, also known as glycolysis, is the process which releases energy stored in glucose by combining it with oxygen. During glycolysis, carbon, hydrogen and oxygen in one molecule of glucose recombine with six molecules of oxygen. The products of one molecule in glucose in glycolysis include six molecules of carbon dioxide, six molecules of water, and energy molecules called ATP and NADP. ATP, or adenosine triphosphate, is the primary energy source that cells use to perform their functions.

The cerebrum is the largest part of the human brain. It has two halves which are connected by nerve cells and fibers called the corpus callosum. Each half of the cerebrum is further divided into lobes. They are the frontal, parietal, temporal and occipital lobes.\nThe diencephalon contains the hypothalamus, the subthalamus and the thalamus. The hypothalamus controls functions such as hunger and thirst, and emotions such as fear and anger. The subthalamus and the thalamus carry impulses to and from other areas of the brain.\nThe medulla oblongata is an extension of the spinal cord into the back..

Record your starting value in micrometersStart your equation by writing down, or inputting into a calculator, the micrometer value that you wish to convert to centimeters.Divide your micrometer value by 10,000If you have 1 micrometer, divide 1 by 10,000. A quicker way to work this equation is to move the decimal point to the left four places.Record your answerWrite down your answer, which shows that 1 micrometer is equal to 0.0001 centimeters.
