What is the evidence for sea-floor spreading? Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves.
By studying the magnetic properties of rocks, scientists can identify magnetic reversals and patterns that support the process of seafloor spreading and the movement of lithospheric plates. A convergent plate boundary is where two tectonic plates move towards each other.
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.
Past the subduction zones where land and ocean plates collide. The diagram shows the magnetic polarity (they look like zebra stripes) of the seafloor at the Mid-Ocean Ridge.
Seafloor spreading is a key process in plate tectonics. It happens at mid-ocean ridges where new oceanic crust forms as plates move apart. This process creates and expands ocean basins, driving the movement of tectonic plates.
8 Οκτ 2024 · Key Contributors to Plate Tectonics. Bruce Heezen, Marie Tharp, and Henry Menard collaborated to map the ocean floor, revealing critical features such as mid-ocean ridges. Their work provided visual evidence of seafloor spreading, supporting the theory of plate tectonics.
