HEAVY RAINS

 made our first ocean( it is salty because of the natural minerals of the rock and soil that flows into rivers, and when it reaches the ocean, the water evaporates, leaving the salt behind. 

PANGAEA THEORY

(single supercontinent)

ALBERT WEGENER

German Geologist & Meteorologist observed that continents fit together like a “puzzle”

-continents slowly moved due to earth’s active core

Tectonic plates-

 huge rigid pieces of the earth’s lithosphere

-fit together like a puzzle

Divergent

move away=ocean ridges

Convergent

head on/subduction=mountain, trenches, volacanoes

Transform

slide past each other horizontally= fault strong earthquake

Seafloor spreading

occurs at mid -ocean ridges

-new oceanic crust from magma forms as plates move apart

Mid-Atlantic Ridge

long mountain range '

movement pushing apart

Pacific ocean

63M mi2/2,000 fathoms

Camotes Sea

386 mi2/ 100 fathoms
