WebApr 16, 2024 · Which is the first step in the seafloor spreading process? 1. A long crack in the oceanic crust forms at a mid ocean ridge. 2. Molten material rises and erupts along the ridge. How does seafloor spreading affect the environment? The rate of spreading determines how much CO2 is released to the atmosphere. WebIn the general case, seafloor spreading starts as a rift in a continental land mass, similar to the Red Sea - East Africa Rift System today. [16] The process starts by heating at the base of the continental crust which …
WebNov 3, 2024 · What is the first step in seafloor spreading 2 See answers Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of … WebAccording to Continental Drift Theory, the process of seafloor spreading is the reasonwhy continents drifted apart.4. According to the Seafloor Spreading Theory, continental plate is the actual site oftectonic activity where seafloor spreading occurs.5. Based on Continental Drift Theory, it is in the oceanic plate where tectonic activityhappened.
WebOct 14, 2024 · Wherever the sea floor is spreading, the edges move apart while the magma in the middle hardens. That means the rock in the center is the youngest. As the continents move apart, whole new... WebQ: What causes the movement of lithosphere plates ? A: The interior is categorized primarily into the crust, the core, and the mantle. The lithosphere and ... Q: Name a structural feature that is formed at convergent plate boundaries.

WebApr 9, 2024 · One of the two major processes of plate tectonics is seafloor spreading, while the other being subduction. The renowned examples of mid-ocean ridges are the Mid- Atlantic Ridge and the East Pacific Rise. Seafloor spreading occurs at mid-ocean ridges and obtains basalt, the rock that forms the oceanic crust. Subduction zones are often … green coated bulletsWeb1. The seafloor at a subduction zone sinks. 2. Crust spreads along an ocean ridge and magma fills the gap that is created. 3. New seafloor moves away from the ridge, cools, and becomes more dense. 4. Hot magma … flowrite sloan drop in kitWebDec 9, 2024 · Seafloor spreading gradually pushes tectonic plates apart at mid-ocean ridges. When this happens the opposite edge of these plates push against other tectonic plates. Subduction occurs when two tectonic plates meet and one moves underneath the other (Fig. 7.23). flowritethermalWebApr 11, 2024 · An understanding of the research process is an essential skill for designing a study and developing the research protocol.

Seafloor spreading is the process of magma welling up in the rift as the old crust pulls itself in opposite directions. Cold seawater cools the magma, creating a new crust. The upward movement and eventual cooling of this … flowrite steam valveWebThe process begins when the mantle is heated beneath the core. As heated it rises in the crust (divergent boundary) commonly it rises in a divergent boundary. As it rises magma flows out and create new seafloor. Then the old seafloor was pushed in a convergent boundary to subduct in the mantle and burns. As known it repeats itself again and again. green coated chainWebIn the general case, seafloor spreading starts as a rift in a continental land mass, similar to the Red Sea-East Africa Rift System today.
