Friday 2/22/19 Please have your book as well. Bell Ringer: Give two examples of how plate tectonics (movement of earth’s crust) changes Earth’s surface.
2
Converging Plates 2 plates move towards each other.
Different density in the crust = 1 sinks and creates a deep ocean trench & volcanoes. Same density in crust= both go up creating mountain ranges. 5
3
Oceanic and Continental
Plate types Oceanic and Oceanic Oceanic and Continental Continental and Continental Volcanoes 5 Mountains - Himalayas
4
Divergent Plates 2 plates move apart
ocean crust moves apart = a mid-ocean ridge crust moves apart on land = deep valley called a rift valley. 7
5
Continent Crust Ocean Crust
6
Rift Valley in Iceland
7
Transform Plates 2 plates slip past each other moving in opposite directions. Earthquakes often occur as the plates slip past each other.
8
Transform Plates San Andreas Fault in CA
Maybe draw a picture of a road going across the fault. Ask students what would happen when the two plates began to move.
9
7 Put landforms activity under doccam. Do the first (mountains) together. Make sure to label the illustration with the two types of crust and any other important features.
10
Plate tectonics is the cause of…
Continental Drift Size and shape of the oceans Earthquakes Volcanoes Mountain Ranges Deep-ocean trenches Mid-ocean ridges Rift valley

Type of Plate Boundary = Red Dice Type of Crust = Green and White Dice
Plate Tectonics Dice Review Game Carefully read and follow the directions on the handout. Type of Plate Boundary = Red Dice Type of Crust = Green and White Dice White Dot Convergent Boundary Blue Dot Oceanic Crust Green Dot Divergent Boundary Red Dot Continental Crust Yellow Dot Transform Boundary
