when the earth shakes earthquakes volcanoes and t quakes are sudden releases of energy within the Earth's crust that generate seismic waves. They are primarily caused by: Tectonic Plate Movements Most earthquakes are a result of the interactions at plate boundaries: Transform Boundaries: Plates slide past each other horizontally (e.g., San M Miss Kara Ankunding Jan 16, 2026
volcanoes through time fast forward to significant planetary changes, while modern volcanoes tend to be more localized. Changes in Earth's crust, tectonic activity, and atmospheric conditions have influenced volcanic activity and appearance over time. W L Lavonne Dare Jul 29, 2025
