Grouping practices for reading instruction play a critical role in facilitating effective implementation of both reading instruction and inclusion of students with disabilities in general education classes.
What drives the process of plate tectonics. Tectonic plates are pieces of the Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km thick and consist of two principal types of material: oceanic crust and continental crust. The composition of the two types of crust differs markedly, with basaltic rocks dominating oceanic crust, while continental crust consists principally of lower density granitic rocks.
Â· just now. Report Abuse. Tectonic plate movement creates ocean basins at mid-oceanic ridge by vulcanism from due to decompression of upwelling of convecting mantle. It is not the tectonic plates that create this movement; convection of the mantle does that. Since tectonic plates are mechanically coupled to the aesthenosphere they are pulled along as the mantle convects.
