A SCIENTIST HAD A THEORY THAT THERE ARE CRACKS IN THE CONTINENTS SO HE COMBINED H

THEORY ABOUT PLATE TECTONICS

• They think gravity pulls one edge of the plate and the rest of it moves to
• Then they will either collide,pull apart,or grind past each other.
• When it does that it will change earths surface by creating volcanoes
• Or mountain ranges or deep ocean trenches

PLATE BOUNDARIES

• Plate boundaries is where plates meet
• They move very slowly apart from each other

DIVERGENT BOUNDARIES

• It is a place where plates move apart
• When it happens on Earth two of Earths plates move apart

CONVERGENT BOUNDARIES

• Its where two plates come together or converge
• When they converge its called a collision

TRANSFORM BOUNDARIES

• Its where two plates slip past each other going in opposite directions

PLATE MOTIONS OVER TIME

• When ever plates move it changes Earths surface
• It has made it change a lot over time
