The Richter magnitude test scale (or more correctly local magnitude ML scale) assigns a single number to quantify the size of an earthquake. It is a base-10 logarithmic scale obtained by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a seismometer output. Measurements have no limits and can be either positive or negative.

The definitions are correct, the Richter scale is used to rate the intensity of earthquakes. The machine with the ink and pointer drawing the bouncy lines is a seismograph.
The numbers on the Richter scale represent powers of 10. That means that a magnitude 2 earthquake is 10 more intense than a magnitude 1. A magnitude 3 earthquake is 100 more intense than a magnitude 1. A magnitude 4 earthquake is 1000 more intense and so on.

Richter scales is an instrument used for measuring the intensity of an earthquake ranging from 0-9 in a logarithmic pattern.

I think it is a scale to measure the force of an earth tremor. Those graphs with feeding ink and rolling paper get the information. An 8 on the Richter scale is an earthquake you would feel for example.

Richter scale was invented by one Mr Charles Richter in Pasadena university in the year 1935. He has used a seismograph machine to find the force released by earthquakes for the local California only. It is open ended scale. No upper limit for it By studying the recorded graph from seismograph seismologist can find the distance of epicenter and the amplitude of shaking. These parameters are used to calculate Richter scale. The energy release from one to next is 10 times more in shaking and 32 times more in energy release. It is logarithmic.

richter scale is the rate of two earthquake waves that shows how much energy is release in a earth quack each earth quack contain 3 wave .the richter number always between 1 and 9 .it never could be more than 9

how earthquakes are measured. I think each number is roughly double the intensity of the number before it. A 4 is strong enough to feel- an 8 would probably decimate your region.

an instrument that measure the Gound/earth movement (like the earth quake)

it is a tool that measures the eatrh's seismic acticity.
