Is the sun bigger than the moon and Earth?

Jupiter is the largest planet in the solar system, with a diameter of roughly 88,846 miles. Mercury is the smallest, with a diameter of only 3,032 miles, and it is also closer to the sun than any other planet. The planet farthest from the sun is Neptune, at 2,798,842,000 miles away. The Earth is approximately 92,957,100 miles from the sun.

What is a plug dome volcano?

Plug dome volcanoes expand from within. As they grow, the outer surface cools and hardens, then shatters, spilling fragments down its sides. The size and shape of plug dome volcanoes vary from one volcano to the next. The most notable differences between plug dome volcanoes are found in the shape of the dome. The form of the dome depends on a number of factors including the strength and viscosity of the lava, as well as the slope of the surrounding area.\nPlug dome volcanoes can form wherever volcanic activity is present. Typically these formations occur in the craters of larger volcanoes. How..

How do I make a bean plant growth chart?

Divide the y-axis into even units of height, each of which should represent a linear measurement, such as inches or centimeters. For example, the first division may represent a plant that has grown 1 inch by a given time. Divide the x-axis as the y-axis was divided, but this axis should display units of time. For example, the x-axis may be divided into days, weeks or months. Make a dot on the graph that indicates how tall a plant was at a given time. Do this for each of the dates listed on the x-axis. Connect these dots to produce a line graph to measure and track the growth of several differe..

What is the difference between a monosaccharide and a disaccharide?

Both disaccharides and monosaccharides are a form of carbohydrate called simple sugars. Monosaccharides contain one sugar and disaccharides contain two sugars, and for a disaccharide to form, two monosaccharides must come together via a covalent bond. Many sugars present in foods are disaccharides, and they also exist in nature in the sucrose contained in fruits and vegetables. Sucrose cannot be hydrolyzed (adding water to cleave chemical bonds) but other disaccharides can be.\nThe simplest type of carbohydrate is the monosaccharide. Since they are the simplest form, further hydrolyzing is not..

How cold does it have to be to snow?

At 32 degrees Fahrenheit, water vapor in the atmosphere freezes, turning into tiny ice crystals. These collide to form snowflakes, which are too heavy to remain aloft. Most heavy snowfalls take place when there is modestly warm air, which holds more moisture, near the ground that melts the edges of the flakes, causing them to refreeze with others. Windy air or air below 19 degrees Fahrenheit produces smaller, dryer snowflakes that do not stick together as well.

What is a warm air mass that is cut off from the ground said to be?

There are two different kinds of occluded fronts. The first is cold occlusion, which is similar to a cold front. This happens when the air behind an occluded front is colder than the air in front of it. The colder, heavier air mass lifts the warmer air above itself.\nThe other type of occluded front is warm occlusion, which acts like a warm front. In this type, the air behind the occluded front is warmer than the air in front of it.

What is a slug line?

Reuter's handbook for journalists provides detailed guidelines to writing slugs, which are used to code a story for proper identification and routing. Slug lines may also refer to a specific form of carpooling around the Washington, DC area in which drivers pick up strange passengers in an organized commuting community that follows a strict set of protocols.

What is Venus' period of revolution?

Venus takes 243 Earth days to make a complete rotation upon its axis, meaning that Venus has a day that is longer than its year. However, due to the retrograde rotation of the planet, the time between sunrises is only 117 Earth days. Venus is the second planet from the sun in the solar system and is often called Earth's twin due to its similar size and composition.

What comes first, length or width?

However, some people may replace length, altogether, with height, especially if the shape they are referring to is drawn with horizontal and vertical sides. In these cases, width might be listed first before height, particularly if the width measurement is bigger. There is no specific rule for this usage of mathematical description. People tend to list the bigger measurement first, no matter what it describes, in order to make measurements a little more easy to understand. The aim is to list the measurements in a way that is sensible and clear. Because of this, length commonly comes before wid..

What determines the chemical properties of an element?

An element is a substance made exclusively from one type of atom and which cannot be broken down further into smaller particles by nonchemical reaction. An element is identified by the number of protons contained in the nuclei of its atoms. All the elements are listed in the periodic table with such details as chemical symbols. An element’s positioning in the periodic table is essentially determined by the number of electrons, the group is determined by the number of valence shell, and the elements block is determined by the type of orbital in which the valence electron is located.\nChemical..
