Three seismographs
Three seismographs are needed. A circle is drawn from each of the three different seismograph locations, where the radius of each circle is equal to the distance from that station to the epicenter. The spot where those three circles intersect is the epicenter (Figure 13.12).
Map projections can vary on distance, scale, and shape the accuracy and strength and weaknesses depends on the distortion, if you google each type of map and the strength and weaknesses, your answers should come up, just look for and consider the variables I said
True
It was made known after 550 BCE when a monk snuck the silk worm out of the country.
The city of Los Angeles released 96 million "shade balls" into the Los Angeles Reservoir. These will serve to shield the water from the sun's heat in order to reduce evaporation and prevent algal and bacterial growth so no toxic substances are produced in the water. The balls reduce evaporation by 85%-90% so will save a lot of water yearly.
