Plate Tectonic Hazards

Front 1

Continent-Continent convergent

Back 1

Fold, melt and belts
Earthquakes

Front 2

Continent-continent divergent

Back 2

Hazards: earth quakes
OOZING volcanoes. Not explosive.
Rift valleys. Pulling apart. Growing widercontinent is growing apart.
East African rift valley

Front 3

Ocean-Ocean convergent

Back 3

earth quakes
Trenches
EXPLOSIVE volcanoes.
Older plate goes under newerwaterlower melting pointsudden explosion
Island arcs. Entire edge of newer plate (less dense) is pushed up.
Example: Japan, Indonesia.

Front 4

Ocean-Ocean divergent

Back 4

Earth quakes
Oozing volcanoes
Ridge: (like “rift” for continent-continent) continents pull apartholeoozing magmabigger sea bed.
Ex: mid-Atlantic ridge

Front 5

Ocean-Continent convergent

Back 5

Earth quakes
Trenches
Volcanic Mountains; explosive.
Ex: Andes.

Front 6

Transform plates

Back 6

Earth quakes.
Ex: Faults; Haiti

Front 7

Hot spots

Back 7

weak spot in crust.
Volcanoes
Earth quakes.
Weak spot in crustmagma comes upisland. Continent shiftsold island shifts offnew island
Not only in ocean; underneath continents.
Ex: Yellowstone and Hawaii.
