1 EQ: Why does the surface of the Earth change?
125 Evidence of Continental Drift Evidence of Continental Drift 126 12/14/15 12/14/15 EQ: Why does the surface of the Earth change? Application/ Starter: Look at the pie chart. What are the four most abundant elements in order from least amount to greatest amount in the layers of the earth? Connection/, Exit: What are your ideas about how the continents are able to move? Practice:

2 Look at the pie chart on the left
Look at the pie chart on the left. What are the four most abundant elements in order from least amount to greatest amount in the layers of the earth? Starter  Iron 5%, aluminum 8.13%, silicon 23.77%, oxygen 46.6%

9 Historical Evidence: Mesosaurus
Description: freshwater, crocodile-shaped reptile, approximately 1 m long Location: Africa, South America

10 Sea Floor Spreading: Process by which new oceanic lithosphere forms at mid-ocean ridges

11 Ocean floor is pushed away from mid-ocean ridge by the formation of new ocean floor

12 Mid Ocean Ridge A large system of underwater mountains that have a deep crack running through the center. This deep crack is called a rift valley. .

13 Forms the single largest mountain chain in the world.
Mid Ocean Ridge Forms the single largest mountain chain in the world.

14 Formation of new oceanic crust begins at the mid-ocean ridges
Formation of new oceanic crust begins at the mid-ocean ridges. The farther away the crust from the ridge, the older the crust is. As the new ocean floor is formed, it pushes any continents with it. This explains continental drift.

15 Ocean trenches are the deepest part of the ocean
Ocean trenches are the deepest part of the ocean. They are found close to some continents or near islands. As the ocean floor spreads, it eventually moves down deep into the Earth along the trenches. The process by which crust plunges back into the Earth is called subduction.
