Describe two characteristics of the crust.
it is solid, constantly in motion, 0- 900°C, can be either granite or basalt, 6–80km thick.

Explain the causes of tectonic plate motion
Radioactive decay in the core is a heat source.
3 of 7
describe and explain the location of volcanoes
Describe: volcanoes are located at plate margins, such as between the South American and Nazca Plates; these are destructive plate margins and can form volcanic arc island chains; volcanoes are found at isolated hotspots, e.g. Hawaii, not at plate ma
