he theory that early Proto-Indo-European speakers spread westward on horseback, overpowering earlier inhabitants and beginning the diffusion and differentiation of Indo-European tounges. Dispersal Hypothesis.
East Asia's coastal, island and peninsula area are similar as they lie on the Ring of Fire. Accordingly, every one of these territories has tremors and volcanoes. Be that as it may, they additionally have hot springs. These ranges are unique in relation to inland regions due to the elevation: the island is more tough and rocky than the beach front, island and promontory zones.
Wind erosion is the main cause. And since it is the desert that wind can pick up tiny sand rock particles that slowly grind against the rock. Over time the erosion will give a jagged rock the smooth features as if it had been submerged in a river for the roughly same period of time.
To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
