What is an example of an asthenosphere? The asthenosphere, in its capacity as a quasi-liquid, has convection currents that extend throughout its whole surface, under the entire area of the plates. The upper layer of asthenosphere under the South American plate, for example, is moving inexorably westward. What is the asthenosphere made of? The asthenosphere […]

When balancing equations do you balance charges?
When balancing equations do you balance charges? Balance charge. Add e- (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the […]

What determines if a single replacement reaction will occur?
What determines if a single replacement reaction will occur? where one element is substituted for another element in a compound to generate a new element and a new compound. We predict a single replacement reaction will occur when a less reactive element can be replaced by a more reactive element in a compound. Is Rusting […]
What happens to the difference in arrival time between P waves and S waves as the distance from the epicenter increases?
What happens to the difference in arrival time between P waves and S waves as the distance from the epicenter increases? The time between the arrival of the p-wave and s-wave becomes greater and greater as the distance from the epicenter increases because p-waves have a faster velocity than s-waves, meaning p-waves arrive at a […]
