What is igneous rock?
What is convergent?
The term for magma that has emerged from a volcano
What is lava?
What topographic maps show
What are the surface features and elevation of the earth?
What is the epicenter?
Sedimentary rocks are directly made by weathering (true/false)
What is false?
The process that creates mid-ocean ridges
What is seafloor spreading?
The name of the region around the Pacific plate known for its high volcanic activity
What is the Ring of Fire?
Lines that connect all points at the same elevation on a topographic map
What are contour lines?
The point on a fault where the first movement occurs
What is the focus?
The cause of metamorphic rocks formation
The plate boundary that most commonly produces earthquakes
What is a transform boundary?
What are subduction zones?
Dashed lines showing a decrease in elevation on a topographic map
What are depression contours?
Vibrations that radiate outward in all directions from earthquakes
The term for weathered rocks and minerals
What is sediment?
The term for a spot in a plate where volcanoes occur, away from any plate boundaries
What is a hot spot?
The most dangerous type of volcano
What are stratovolcanoes?
Difference between the highest and lowest point on a topographic map
What is the relief?

Igneous rock formed above ground
The theory that all tectonic plates were originally in one supercontinent before breaking apart
What is Continental Drift?
The name of a superheated plume of fast-moving gas that has emerged from a volcano
What are pyroclastic flows?
Every 5th contour line in bold, labeled with the elevation number
What is the contour index?
Theory that stress builds between 2 plates locked in place by friction, then the plates overcome friction causing them to move. The plates then snap back to their former shape.
What is Elastic Rebound Theory?
