The earth beneath you is solid ground made up of rock, soil, and other materials. The past tense of "grind" is "ground."

When Earth's tectonic plates grind past each other and a fault forms, it can result in an earthquake. The stress built up along the fault is released suddenly, causing the rocks on either side to move. This movement generates seismic waves that we feel as shaking on the surface.
When rocks grind and squeeze past each other due to tectonic forces, dynamic metamorphism can occur. This process can lead to the formation of mylonites, which are fine-grained rocks with a strong foliation formed from the intense deformation.

Volcanoes form at boundaries where tectonic plates converge, diverge, or slide past each other. This can lead to the buildup of molten rock beneath the Earth's surface, which eventually erupts through a vent to create a volcano.
The area of Earth science that examines the physical and biological changes that have occurred in the Earth's past is called paleontology. Paleontologists study fossils and other evidence of past life to understand how Earth's environments, climates, and ecosystems have evolved over time.
