Tectonic plates are huge plates of rock covering the surface of the earth. They are very slowly moving, some moving together, some moving apart.
Sometimes they have been pushing or pulling a bit without any movement until suddenly they give a jerk. That jerk is usually an earthquake.
The natural disaster from the movement of tectonic plates is an earthquake, and if it's under the sea, then it might cause a tsunami.
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
