Web26 jun. 2024 · Changes in global sea level have been ongoing throughout the Earth’s geological history, driven by the growth and decay of ice sheets. The Last Glacial Maximum – when ice sheets were at their greatest extent – occurred as early human communities were developing, often focused in coastal areas such as the Mediterranean Basin. Web27 sep. 2024 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. george washington\\u0027s great great grandson https://a1fadesbarbershop.com
