Reasons and types of plate movement: Why and how do plates move?
Density: n Density: The amount of matter of a substance in a given space or volume.
Density: n n Density: The amount of matter of a substance in a given space or volume. Density = mass / volume
Density: n n n Density: The amount of matter of a substance in a given space or volume. Density = mass / volume D=m/v
Density: n n n Density: The amount of matter of a substance in a given space or volume. Density = mass / volume D=m/v n The more dense a material is the more it will “sink”.
Density: n n n Density: The amount of matter of a substance in a given space or volume. Density = mass / volume D=m/v n n The more dense a material is the more it will “sink”. The less dense a material is the more it will “rise”.
Density: n D=m/v n Heating a material causes the molecules to move apart which increases its volume.
Density: n D=m/v n Heating a material causes the molecules to move apart which increases its volume. n When volume goes up …. Density goes down
Density: n D=m/v n Heating a material causes the molecules to move apart which increases its volume. n n When volume goes up …. Density goes down What is the density of an object with a mass of 10 grams and a volume of 2 ml?
Density: n D=m/v n Heating a material causes the molecules to move apart which increases its volume. n n n When volume goes up …. Density goes down What is the density of an object with a mass of 10 grams and a volume of 2 ml? What is the density of the same object that still has a mass of 10 grams but a volume of 5 ml?
How do the plates move? : n Convection currents of hot magma in the upper mantle that is part of the lithosphere cause the plates to move as the plates ride around on top of it.

So what can happen?
So what can happen? n Three types of boundaries can form from this movement.
So what can happen? n Three types of boundaries can form from this movement. n Convergent: two or more plates moving toward each other
So what can happen? n Three types of boundaries can form from this movement. n n Convergent: two or more plates moving toward each other Divergent: two or more plates moving away from each other
So what can happen? n Three types of boundaries can form from this movement. n n n Convergent: two or more plates moving toward each other Divergent: two or more plates moving away from each other Transform: two plates that are next to each other move parallel to each other in opposite directions.
Convergent Boundaries
Convergent Boundaries: n Types: n Oceanic-Oceanic: One plate gets subducted (pushed under) the other and a trench is formed as well as undersea volcanoes. Called a subduction zone. n
Convergent Boundaries: n Types: n Oceanic-Continental: The ocean plate is subducted under the continental plate. Called a subduction zone. n Strong earthquakes happen here. n
Convergent Boundaries: n Types: n Continental-Continental: Neither plate is pushed under. Instead they both buckle and push upward. n This is what creates mountain ranges.
