One of these planetesimals developed into earth. The first p wave and the first s wave. Particles in the solar nebula condensed to form solid grains, and with increasing electrostatic and gravitational influences they eventually clumped together into fragments or chunks of rock. An example of a seismic wave with the p wave and s wave labeled.
Determining the distance along the earth's surface from a seismic station to the epicenter of an earthquake is based on the difference in arrival times between. Web 8) why is there virtually no hydrogen and helium present in the atmosphere today? The long answer, and the much more interesting one, begins nearly 200 million years ago. Web it is interesting to note that natural catastrophes devastated the world just as each geologic era ended and another era began to form on earth. To decipher that history, we need to look at the events in sequence. The first p wave and the first s wave. First, the materials were deposited. Web tons of oxygen and tough trees, giant insects and amphibians flying and crawling all over the damn place?
