WebCAUSES OF PLATE MOVEMENTS CONVECTION CURRENT, RIDGE PUSH, SLAB PULL. SEAFLOOR SPREADING THEORY - Hess & Dietz The seafloor is expanding and it started from the ridge. Evidences of Seafloor Spreading Theory 1. Age of Rocks (rock on the mid-ocean ridges are younger than those found on the continents) 1. WebApr 15, 2024 · The motion of tectonic plates is driven in large part by these convection currents. The base of the plates is pulled along by the currents as they rise and expand horizontally beneath the lithosphere. This force, in addition to others like ridge push and slab pull, is what actually gets the plates moving. More about the Ridge Push and ... cod 2 stats

WebMay 23, 2024 · The ridge push occurs at the resilient upwelling mantle at ridges placed on the mid-ocean level. The newly formed plates placed at the oceanic ridges are still warm once they are formed, so their elevation is higher than colder, denser plate material that is placed further in the ridge. WebOct 30, 2024 · Plate fragments connected to slabs drag the mantle, and conversely, fragments that are not attached to any slab are dragged by the interior flow, with fragments pulled by connected slabs moving faster. Increasing basal heating from 4 to 43% leads to higher FD, as it boosts the first cause. WebIt is now thought that a mechanism called slab pull drives the movement of tectonic plates. Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As... calories burned on treadmill 180 pound person
