The Kelvin and Celsius scales are the most used scales for absolute zero.
Two examples of living things covered in scales are snakes and fish. Both of these organisms have scales that help protect their skin and allow for movement in their environments.
Two common scales to measure the temperature of liquids are Celsius and Fahrenheit. Celsius is commonly used in scientific measurements and everyday life in most countries, while Fahrenheit is often used in the United States. Another scale that might be used in specialized situations is Kelvin, where 0 Kelvin is absolute zero.
F, R, C, and K.
A number of scales are used to measure earthquakes. These are broadly split into two main types. Magnitude scales and intensity scales. Magnitude scales give an indication of the amount of energy released during an earthquake and intensity scales give an indication of the sevirity of ground shaking and resultant damage in a given location.
