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.
How does the movement of tectonic plates occur? The layer of the Earth called the mantle is continuously circulating like rice would in boiling water. This movement under the crust cause the plates to shift moving the plate â¦ s to create mountains, valleys, earthquakes, and tsunamis..
