Chapter 7.2 Digital Lesson Flashcards
Do GPS stations have to be constantly moving
No
Since Weathering and erosion and deposition change the earth’s surface, what do they do?
Weathering: breaking of rocks into smaller pieces by physical or chemical means
Erosion: when sediment and materials are moved from one place to another
Deposition: when eroded material is deposited due to gravity
How is oceanic lithosphere different from continental lithosphere
Oceanic lithosphere is thinner and denser then continental lithosphere
What causes tectonic plates to move on top of the asthenosphere
Convection
What 3 landforms may result at convergent boundaries
Ocean teaches, island arches, and mountain chains
What happens when magma rises above earths surface
Forms volcanic mountains and plateaus
What can be found in the middle of rift valleys
Volcanoes
Mid ocean ridge
System of elevated volcanic mountain chains on the ocean floor
What feature suggests that a divergent boundary is on the ocean floor
Mid ocean ridge
What kind of stress occurs at a transform boundary, divergent, and convergent boundary
Transform: sheer stress
Divergent: tension
Convergent: compression
Where the Hawaiian islands formed by a transform boundary?
No they were formed by a hot spot
The movement of tectonic plates causes what to happen to the lithosphere
Deformation
What does GPS stand for
Global Positioning System
