The rich soil of Virginia was well suited for large scale farming.
Slaver in England's North American Colonies was first used on a large scale in the tobacco industry of Virginia. Later on, it was discovered that cotton could be grown in the South, so slaves were then needed in the South.
It is called the magnitude scale. It is a log scale.
Missouri, Kentucky, Maryland, Delaware. Later there was the new state of West Virginia, which quit Virginia (and the Confederacy) to join the Union, although there was very little slavery in that mountain region. Also, the District of Columbia was still practising slavery in the first months of the war (on a very small scale), although slave-trading had been abolished there, as part of the Compromise of 1850.
The inventor of the balance scale is philipp von jolly
There are two systems that measure earthquakes. The Richter scale measures the moment magnitude, and the Mercalli scale measures the intensity of an earthquake.
The mercalli scale was made by Giuseppe mercalli he was born in milan.
the modified mercalli scale was VII-VIII
modified mercalli scale measure is type of seismograph that they made in the 1989
The Mercalli scale is a way of measuring the intensity of damage of an earthquake. It is based upon set criteria. This scale might be used rather than the Richter Scal because the mercalli scale is based upon the observed damages, not set scientific data.
Richter scale, Modified Mercalli scale, Centigrade scale, and the Moment Magnitude scale
different scales
The Richter scale
Mercalli is a scale for the measurement of earthquake intensities.
The two main earthquake classifications are the Ritcher and mercalli scales. The Ritcher scale measures the actual amount of energy released by the quake in a scale of 1-10. Every number in the scale is 10x stronger than the number before it. This is the kind of measurement that would be reported in the news first. Most earthquakes are recorded using this scale. The Mercalli scale rates earthquakes by the signs noticeable during the quake and the damage caused. Having plaster falling off walls, for example, would give a rating of 6 (strong). Note that this scale doesn't indicate the actual intensity of the earthquake.
The size of an earthquake is measured on the Ricter scale it can also be measured on the Mercalli scale.For an example the 2008 earthquake in China was 7.8 on the Rictor scale and in was XI on the Mercalli scale
The Mercalli Intensity Scale is a measure of earthquake intensity experienced at a given location. The Kobe earthquake in 1995 had intensities reaching up to VIII (8) on the Mercalli Intensity Scale in the heavily affected areas around Kobe.
