Movements of Tectonic Plates Flashcards
Tectonic plates are constantly _______.
Moving
Tectonic plates experience 2 type of forces:
Tension and Compression
Occurs when plates are pulled apart causing either an elongation or breakage
Tension
Tension forms what?
Volcanic islands, mid-ocean ridges
Occurs when plates are pushed towards each other causing them to crash
Compression
Compression forms what?
Mountains and Earthquakes
Under compression, it occurs when the Earth’s crust bends away.
Folding
Upward bend
Anticline
Downward bend
Syncline
Happens when the Earth’s crust completely breaks and slides apart each other
Faulting
Faulting causes what?
Earthquake
2 plates against each other
Convergent
3 types of Convergent
- Continental - Continental
- Continental - Oceanic
- Oceanic - Oceanic
Continental - Continental formations:
Mountains
Continental - Oceanic formations:
Volcanoes, Subduction zones
Oceanic - Oceanic formations:
Trenches, Volcanic Islands, Subduction zones
2 plates move away from each other
Divergent
Divergent forms:
Ridges, Valleys, Canyons
- plates slide past each other
-fault line at center
Transform Fault
