WebExplain what Seafloor spreading is and what is caused by it Theory that the middle of the ocean is spreading apart, forming new oceanic crust. Convection currents inside the mantle cause magma to push up through the crust creating oceanic ridges that split and move apart causing the sea floor to shift WebCauses of Seafloor Spreading / Plate Movement - Convection Currents, Ridge Push, & Slab Pull Activity 8 - Week 8 - Earth and Space 10 Total Score: 32/32 12 points CONVERGENT DIVERGENT TRANSFORM Moving towards each other Moving away from each other Sliding past each other Mountains, Faults, Earthquakes, Trenches, … WebDec 2, 2024 · 4.1: The Forces Driving Plate Motions. The motion of tectonic plates is driven by convection in the mantle. In simple terms, convection is the idea that dense, cold things sink, and buoyant, warm things rise. In the earth the cold sinking things are slabs (subducting plates) and the warm things are plumes, or just rising material from deeper … church view medical centre ta19 9rx

WebMay 6, 2024 · Movement of the plates over Earth’s surface is termed plate tectonics. Plates move at a rate of a few centimeters a year, about the same rate fingernails grow. ... Figure 3. Mantle convection drives plate tectonics. Hot material rises at mid-ocean ridges and sinks at deep sea trenches, which keeps the plates moving along the Earth’s surface ... WebPlate tectonics shapes global landforms and environments through the rock cycle, mountain building, volcanism, and the distribution of continents and oceans. These phenomena, ultimately driven by Earth’s internal heat, … dfb webshopWebMantle convection. slab pull process. Most agree that plate movement is the result of the convective circulation of Earth’s heated interior, much as envisaged by Arthur Holmes in 1929. The heat source for convection is thought to be the decay of radioactive elements in the mantle. How this convection propels the plates is poorly understood. dfb webmail

"WebC. convection currents in the mantle. Answer: C. Explanation: the force that causes most of the plate movement is thermal convection, where heat from the earths interior causes currents of hot rising magma and cooler sinking magama to flow, moving the plates of the crust along with them.

WebFeb 19, 2024 · Plate Tectonics. Plate tectonics refers to the process of plate formation, movement, and destruction. It finds its foundations in two theories, continental drift and sea-floor spreading. Continental drift describes the movements of continents over the Earth's surface. Sea-floor spreading refers to the creation new oceanic plate material and ... WebIt will result to the movement of the lithospheric plates in the asthenosphere due to rising and sinking of materials. Finally, the process repeats as cycle. The convection current is the mechanism demonstrated by Harry Hess which allowed the continents to drift, proving that Alfred Wegener’s theory of continental drift is plausible.
