The answer would be conservative plate boundaries.
They occur where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement. The shockwaves created produce an earthquake.
I hope this helped and is correct! :)
When Went placed the agar block on one side of the decapitated shoot, the shoot curved away from the agar as it grew. This demonstrated that some kind of hormonal signal had diffused into the agar from the coleoptile tips. ... Went's experiment represented the first time that anyone had isolated a hormone from plants.
D prevents repeating. experiments have to be repeated to be reliable.
