Richter Magnitude is an estimate of the amount of energy released during and earthquake.Upon completion of this activity you will be given the opportunity to receive a personalized Certificate as a "Virtual Seismologist." In order to get this certificate, you must make careful measurements throughout the activity.Alpha decay is usually restricted to the heavier elements in the periodic table.(Only a handful of nuclides with atomic numbers less than 83 emit an -particle.) The product of -decay is easy to predict if we assume that both mass and charge are conserved in nuclear reactions.
The energy given off in this reaction is carried by an x-ray photon, which is represented by the symbol hv, where h is Planck's constant and v is the frequency of the x-ray.
(After you complete Virtual Earthquake, check out the Geology Labs On-Line home page for the latest information about project activities.
Activities about age dating, river discharge and river flooding are available.) will show you the recordings of an earthquake's seismic waves detected by instruments far away from the earthquake.
This process is often called "cosmic evolution" or "cosmological evolution"; while the terms are used by those both inside and outside the astronomical community, it is important to bear in mind that BBT is completely independent of biological evolution.
Over the last several decades the basic picture of cosmology given by BBT has been generally accepted by astronomers, physicists and the wider scientific community.
