WebThe plates move under horizontal forces that cause them to collide, combine, break up, or, in the case of oceanic plates, to be drawn down (subducted). The forces that act on or near mid-oceanic ridges are called ridge-push force. It is driven by upwelling magmas from mantle regions that drive the plates away on either side of the ridge. WebIn this model, students will discover how convection currents in the Earth’s mantle cause tectonic movement. This activity is meant to be done as a teacher demonstration due to the use of very hot water. Grade Levels 6-8 Student Outcomes Students will: • Describe and model how convection currents cause tectonic plate motion.

What kind of currents in the mantle cause the tectonic plates to …

WebThe development of plate tectonic theory. Scientists agree that the plates move, but there is still debate over the mechanisms that cause the movement; Mantle convection. In the past, the theory of convection currents was used on its own to explain tectonic plate movement; Heat from radioactive decay in the core moves upwards into the mantle WebThe plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the … paragon casino marksville rv park
