However, modern geophysics organizations use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial relations; and analogous problems associated with the Moon and other planets.

Although geophysics was only recognized as a separate discipline in the 19th century, its origins date back to ancient times.

They are often in the form of fossil trees that were buried upright and which often cross multiple layers of strata such as sandstone, shale, limestone and even They range in size from small rootlets to trees over 80 feet long.

Sometimes they are oblique (or at an angle to) the surrounding strata, but more often they are perpendicular with (or standing 'upright' in) it.

When an isotope emits an alpha particle, the resultant daughter product has an atomic number two units less than its parent's atomic number, and an atomic weight four units less than its parent's atomic weight.

When an isotope emits a beta particle, it decays to a daughter with an atomic number one unit greater and an essentially unchanged atomic weight.

Was the great majority of the world's sedimentary strata laid down by a single Worldwide Deluge in a short amount of time, or is the evolutionary scenario of slow change, acting over eons of TIME and the associated Geological Time Chart (with its millions and millions of years) a more accurate account of Earth history and how we came to be?

Radioactive isotopes (also called , which is an electron, or negatively charged nuclear particle.Beta particles originate in the nucleus, presumably by breakdown of a neutron into its proton-electron components.Gamma rays are released during both types of radioactive decay.So you have my sympathy, my prayers and my warm regards.After two hundred years of Darwinism, in creation vs.
