Which steps do geologists use to find the epicenter of an earthquake?

Geologists appropriate seismic streams to determine an earthquake's epicenter.

You first require to record the coming times of the P waves and S waves from the seismograph and then deduct them.

Once you discover the time variation, you then require to look on a distance-time plan to discover how far from the epicenter that 1 seismograph is.

Then, on your map, using the map's scale, you need a compass and initiate the compass just to the distance you determined on the distance-time graph.

Using the area of the seismograph as the center-point, trace around with the compass. The range of your circle should be equivalent to the measure from the distance-time graph.

You later need to do this alike calculation for two additional seismographs. Where the three circles meet, such is the epicenter of that earthquake.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
