QUESTIONS LIST:

• asthenosphere : solid layer with plasticity in the upper mantle just below the lithosphere
• convergent : what type of plate boundary collides with the other to create mountains?
• transform : what type of plate boundary slides past the other to create fault lines?
• himalayas : what mountain range formed from the collision of the india and eurasia plate?
• hotspot : area in the mantle from which magma rises from a narrow plume to form volcanic mountains
• convection current : heated, less dense air or liquid rises and cooler, more dense air or liquid sinks
• subduction : when two plates collide and the more dense one sinks under the earths surface
• continental drift : theory that continents were once one big land mass and over time they drifted apart
• hawaiian islands : what islands were formed over a hotspot?
• aleutian islands : what islands were formed from the collision of two oceanic plates?

• seafloor spreading : when magma oozes from mid ocean ridges, creating new crust that gradually moves away from the ridge and makes one ocean bigger and the other smaller
• divergent : what type of plate boundary pulls away from the other to form rift valleys?
• lava : magma that has reached the surface
• fossil : materialized remains of organisms that show how long an animal lived and the structure of their body
