Sea floor spreading, adds new material to the seafloor. What happens to old oceanic crust as new molten material rises from the mantel? The new material spreads out which ends up pushing out the older material away
15 Φεβ 2021 · Which of these also describes the current theory of plate tectonics? a. it combines elements of continental drift and seafloor spreading. b. it suggests that the lithosphere is divided into pieces, called plates.
2 Σεπ 2024 · Magma rises from the mantle and fills the gap, solidifying to form new crust. As the new crust is created, older crust is pushed away from the ridge, leading to the spreading of the seafloor. This process plays a crucial role in plate tectonics and the formation of ocean basins.
seafloor spreading. a parallel pattern of rock material found at identical locations on each side of the Mid-Atlantic Ridge reveals rock of the same geologic age and polarity. A tectonic plate boundary where two plates collide, come together, or crash into each other.
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.
21 Μαρ 2023 · Do you know about tectonic plates and sea-floor spreading? To test your knowledge on the same, take this sea-floor spreading and plate tectonics quiz. As you know, sea-floor spreading is the process where Earth's lithosphere spreads apart.
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.
