PLATE TECTONICS

2.

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.

3.

COVECTION CURRENTS

4.

The flows that transfers heat through a fluid.

5.

SLAB PULL

6.

The pull of gravity on a plate that is being subducted

7.

RIDGE PUSH

8.

New crust forming at divergent plate boundaries pushes older crust out of the way as older, denser crust gets pulled away by gravity

9.

DIVERGENT

10.

Plates move away from each other

11.

RIFT VALLEY

12.

Land form that results from a divergent plate boundary.Northeast Africa, near the Horn of Africa.
Is a example

13.

MID OCEAN RIDGE

14.

Understand landform that is caused by a divergent plate boundaries.The Mid Atlantic Ridge is a example.

15.

CONVERGENT PLATE BOUNDARY

16.

is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.

17.

OCEAN VS CONTINENT EXAMPLE

EXAMPLE IS: PACIFIC "RING OF FIRE"
18.

OCEAN VS OCEAN EXAMPLE

EVERYTHING IS HAPPENING UNDER THE OCEAN
19.

CONTINENT VS CONTINENT

EVERYTHING IS HAPPENING ON THE CONTINENT
20.

SUBDUCTION ZONE

21.

the collision between two of the planet's tectonic plates

22.

DEEP OCEAN TRENCH

23.

A long narrow steep sided depression in the earths oceanic crust usually lying above the subduction zone

24.

EXAMPLE OF DEEP OCEAN TRENCH

2 PLATES IN A DOWNWARD WAY
25.

TRANSFORM PLATE BOUNDARY

26.

these faults neither create nor destroy lithosphere, is a type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction.

27.

EXAMPLE OF TRANSFORM PLATE BOUNDARY

28.

Since transform boundary doesn't cause any harm to any thing it just sits there

29.

A paper written by Gerya theorizes that the creation of the transform faults between the ridges of the mid-oceanic ridge is attributed to rotated and stretched sections of the mid-oceanic ridge.
