They are hard solid with a crystal lattice structure... with high melting points
If all plate motion stopped, Earth would be a very different place. The agent responsible for most mountains as well as volcanoes is plate tectonics, so much of the activity that pushes up new mountain ranges and creates new land from volcanic explosions would be no more. The volcanoes of the Pacific Ring of Fire, in South and North America, Japan, the Philippines, and New Zealand, for example, would shut off, and the steady southeastward migration of volcanic activity along the Hawaiian Islands would stop. Volcanism would just continue on the big island. There would also be far fewer earthquakes, since most are due to motion of the plates.
Answer:
When the no. of moles of reactant gases (a + b) = the no. of moles of product gases (c + d).
Explanation:
- The relation between Kp and Kc is:
Kp = Kc(RT)∧Δn.
- So, Kp = Kc, when Δn = zero.
- Δn is the difference between the no. of gas molecules in the products side and that in the reactants side.
- So, Δn = zero, when the no. of molecules of gases in the products side = the no. of molecules of gases in the reactants side which means (a + b) = (c + d).
