1. Driving Forces and Effects of Plate Tectonics

2. Causes of Plate Movement
Mantle convection: The process in which heat from Earth’s inner and outer cores is transferred through the mantle
Energy source for convection: heat of Earth’s interior
Gravity pulls down the cooler, more dense region of the mantle

3. Hot Spots
Hot spots: regions of volcanic activity in the interior parts of plates away from plate boundaries
Examples: Hawaii and Yellowstone

4. Hot Spots
Hot spots occur where rising magma from the lower mantle remains stationary for millions of years.
As a plate moves over the rising magma, melting of the plate occurs.
Hot spots are regions of intrusive and extrusive volcanic activity that can build volcanoes and lava flows put up regions of the crust to form mountains

5. KEY IDEA: The hot spot is stationary… the plate moves creating an island chain

7. Other Effects of Plate Tectonics
Environmental hazards (ex. Earthquakes)
Changes in Earths’ climate and weather
The rock cycle
Major landscape feature of Earth (ex. Mountains, plains, oceans)
Exposing rocks to weathering and erosion providing new information
