Why doesn't subduction happen at a continent-continent boundary? Select the BEST answer. A. Continental crust all has the same relative density

B. Water is what causes subduction, and since continent-continent boundaries don't have water, there is no subduction

C. Continental crust is stronger than oceanic crust

D. All of the above

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the correct answer is:

a. formation of precipitation

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

answer; 4 electrons;
