What is the size scale?

The scale size is a numerical reference tool, most often used to describe either an earthquake or a star brightness, as can be seen from the ground. The scale that is most often used to indicate the brightness of the star or their "apparent size" is called an astronomical size scale. The Richter scale and the torque of the size are used to describe the earthquake. The higher the size of the star size, the appears. For example, the brightness of the sun, our closest star, is about -26, while the full moon is assigned to a size of about -13.

The observer in the urban area will be able to see some stars at night, but no dimmer than the size of three. Someone in a rural area can see stars as matte as size six or seven and telescope brings a number to almost ten.Telescopes allow us to see many dim -most stars up to 30.Bones three, because the light of the comet extends over a larger area.

Those who lived in areas susceptible to the earthquake or who studied them to any degree may be somewhat familiar with the Richter scale, used to measure the size of the earthquake. The size of Richter size assigns a single number from one to ten to represent the overall energy by the released earthquake. It is a logarithmic scale with a base of ten, which means that an increase in one unit represents ten times more released energy. For example, an earthquake of 7.0 releases ten times more energy than one measuring 6.0.

The amount of energy released in the earthquake, measured by therichter scale closely correlates with the amount of its destructive potential. For this reason, this is the most widespread measure for measuring earthquakes. It is closely related to Richter's scale is a torque scale. It's also logarithmické but with base 30 than 10.

Moment size of the scale measures energy release as a function of the Earth's rigidity, multiplied by the amount of shift that occurs along the failure, as well as the size of the area that has been moved. Recently, the size of the size of the size began to replace the Richter scale as the most commonly used of both. In practice, the moment of the size of the earthquake is often numerically similar to the value of Richter Scale, causing this switch mostly unnoticed.
