This is why a newline in character encoding can be defined as LF and CR combined into one (LF+CR, LFCR, CR+LF, CRLF). Two ways to view newlines, both of which have valid internal logic, are that newlines terminate lines or that they separate lines.
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving.
Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs. Types of Seismic Waves. There are several different kinds of seismic waves, and they all move in different ways. The two main types of waves are body waves and surface waves.
