Volcanoes

Volcanoes. volcanism : any activity that includes the movement of magma toward the surface of the Earth volcano : place where magma reaches the surface. magma : liquid, molten rock underground lava : magma that reaches the surface lost gas, gained rock. Major Volcanic Zones.

Mountain Orogeny

Mountain Orogeny. Three types of plate boundary. ORIGIN OF MOUNTAINS. Orogeny = process of mountain building, takes tens of millions of years; usually produces long linear structures, known as orogenic belts. Two main processes: 1) Deformation : continental collisions, resulting in

Section 13-2 Review

Section 13-2 Review. Page #330:1-9. #1. Summarize the difference between mafic and felsic magma. Mafic Magma magnesium & iron dark less viscous. Felsic Magma silica & feldspars light more viscous. #2. Explain how the composition of magma affects the force of volcanic eruptions.

VOCABULARY!

VOCABULARY!. Vent-opening in earths crust where lava erupts and flows out onto the surface Crater- Bowl shaped depression that forms around the central vent. Caldera-Large crater that can form when the side or summit of the volcano collapses into the magma chamber during or after an eruption.
