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.
Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.riction increases the heat along such boundaries, which causes this material to melt and mix the oceanic plate material, the continental plate material and the water. Andesite volcanoes tend to form at these subduction boundaries.
