James looked at a picture of rock layers while studying how scientists determine the ages of rocks. He looked at the variety of
layers and understood that the law of superposition indicated something about the rock layer ages. What does the law of superposition indicate? A. The rock layers can change their position and push younger rock layers under older rock layers.
B. The rock layers can change their position and push older rock layers under younger rock layers.
C. The rock layers on top are the youngest layers and the lower rock layers are the oldest layers.
D. The rock layers on top are the oldest layers and the lower rock layers are the youngest layers.
Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
The answer is (A. A warm current flows along the coast.) Currents carry cold and warm water from place to place. It's an amazing phenomenon that scientists are still trying to fully figure out. Some think it's caused by wind, others think it's caused by the shifting of the tectonic plates, but one thing's for sure, currents are VITAL for this planets life.
The original nucleus is known as the <em>parent nucleus</em>, and the core staying after the rot is known as the daughter nucleus
If a core radiates an alpha molecule, it loses two protons and daughternucleus in this way, the little girl core has a nuclear mass of 4 less and a nuclear number of 2 not exactly the parent core
In β-decay, a neutron is changed over into a<em> proton, electron, and electron-anti neutrino</em>
Which builds the nuclear number of the nuclide by 1. <em>For 211Pb, this would bring about a nuclide of 211Bi.</em>
