The melting point of rocks decreases when water is added.
Rocks that have distinct layers of micas are called slate.
Rhyolitic magmas have high gas content.
The Ring of Fire is the name of the chain of volcanoes that surround the Atlantic.
Japan was formed at an ocean hot spot.
Temperature and pressure will cause Igneous rocks to change into Sedimentary rocks.
Intermediate volcanoes are more explosive than basaltic volcanoes.
Dolomite forms from limestone in tropical areas.
Regional metamorphic rocks form when the heat from igneous intrusions alters the
surrounding rock.
Eldfell volcano near the town of Vestmannaeyjar, Iceland formed at a subduction zone.
The oldest ocean crust is about 500 million years old..

Diagram Questions
1.
Draw and label a cross section of an ocean-continent subduction zone. Make sure you label the converging
plates, the volcano(es), ocean trench, subducting crust, oceanic and continental crust, oceans and plate
movement direction. Points will be given for a LARGE, clear drawing with a title. (10)
Explain the formation of clastic sedimentary rocks. You may use diagrams or list the steps in point form. (4).
