Answer:
High pressures and hot temperatures force molten rock to the surface.
Explanation:
In Mount St. Helens' case, an oceanic plate called Juan de Fuca slips under the North American plate, creating the Cascadia subduction zone. A continental arc brews adjacent to the subduction zone, where high pressures and hot temperatures force molten rock to the surface. The result is a chain of volcanoes.
Answer: a) and b)
Explanation:
We can both use titrimetric method and electrical conductivity meter meter to determine the concentration of the ions after which we can calculate the value of Ksp
Answer/Explanation:
Differences in temperature in the mantle cause convection currents. If it weren't for these convection currents wouldn't exist.
The answer is true. I know this because it almost happened to me.
We are asked in the problem to convert teh unit mci or millicurie to another unit of radioactivity, becquerel. The conversion to be used in this case is <span>1 millicurie [mCi] = 37,000,000 becquerel [Bq] .The problem gives 15 mCi which when multiplied to </span>37,000,000 is equal to 5,550,000,000 bQ
