26 Απρ 2024 · The theory of plate tectonics states that Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

28 Απρ 2020 · This science lesson plan aims to teach 10th grade students about seafloor spreading through various classroom activities. Students will learn how seafloor spreading happens, how drill samples provided evidence of spreading, and the lines of evidence that support plate tectonics theory.
29 Νοε 2023 · 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.
