28 Απρ 2020 · Seafloor spreading helps create mid-ocean ridges, giant underwater mountain ranges that develop where tectonic activity is driving plates apart from each other. This lovely map highlights where tectonic plates are separating at mid-ocean ridges.

20 Νοε 2017 · 2) Evidence from seafloor spreading and magnetic stripes on the ocean floor support the theory of plate tectonics, where new ocean crust forms at mid-ocean ridges and spreads outward as the plates move.
30 Ιουν 2012 · 1. The document discusses sea-floor spreading, which is the process where new oceanic crust forms at mid-ocean ridges as tectonic plates move away from each other. 2. Evidence that supports sea-floor spreading includes magnetic stripe patterns in the ocean floor and samples from ocean crust that show it is younger near ridges and older further ...
Plate Tectonic Notes. C. Evidence to support theory 1. fossil records are similar on different continents 2. land forms such as mt. ranges and mineral.
Evidence for Seafloor Spreading. In 1960, Harry Hess studied Wegener’s theory. Hess proposed the radical idea that the ocean floors move like a conveyer belt, which in turn move the...
Rift valleys provide insight into the processes of seafloor spreading, the characteristics of plate boundaries, and the mechanisms driving plate motion, as they exemplify how tectonic activity shapes the Earth's surface.
1) Harry Hess proposed the theory of sea floor spreading in 1962, which suggested that new ocean crust is formed at mid-ocean ridges as tectonic plates move away from each other. 2) Evidence for sea floor spreading includes the flat abyssal plains on the ocean floor and magnetic striping patterns in ocean crust that indicate alternating ...
