CONTINENTAL Political World Map as Pangea 200 -300 Million DRIFT Years Ago MAPS CONTINENTAL DRIFT Political map of Pangea Continental drift is the movement of continents over time.

How is this possible? Internal structure of Earth Continental crust(solid) Continent (solid) Molten magma of Mantle(molten rock) Outer core(dense liquid) Inner core(solid) Because the Earth is still very hot, the plates in the crust can move around on the more molten magma.

Plate Tectonics: Continents drift on Plates

What is Plate Tectonics? The theory that explains the Movement of continents is called Plate tectonics How do plates move? Plates can move away from each other (divergent) Plates can move towards each other (convergent) Plates can pass each other sideways

Conservative/transform boundary Collision boundary TYPES OF PLATE BOUNDARIES Constructive/divergent boundary Destructive/subduction boundary

Building plate boundaries with Oreo biscuits

EVIDENCE ? ? What evidence supports the movement of continents over time? (Important paragraph type question)

EVIDENCE Continen ts fit perfectly ? The east coast of South America and the west coast of Africa match almost perfectly, especially below sea level. ? ?

EVIDENCE Fossil remains match Continen ts fit perfectly Fossil remains of the Lystrosaurus have been found in Africa, India and Antarctica. Could not swim. ? ?

EVIDENCE Rock formatio ns match Fossil remains match Some mountains end close to the coast. Rocks the same type and about the same age Continen ts fit perfectly ?

EVIDENCE Glacier deposits match Rock formatio ns match Ice sheet over continents 300 million years ago. Glacier deposits in Africa, Brazil and Australia match. Fossil remains match Continen ts fit perfectly

EVIDENCE 1 2 3 4 Continen ts fit perfectly Glacier deposits match Rock formatio ns match Fossil remains match

Continental drift refers to theory that explains the movements of the plates and the processes that occur along the plate boundaries. TRUE FALSE

What are tectonic plates like? A Chocolate B Oranges C Jig-saw puzzle C Keyboard

A destructive or subduction plate boundary is represented by…… A B C D

Statement: Continents that fit together is an evidence of continental drift. Example: The west coast of South America and the east coast of Africa match perfectly. Choose from the following: A The statement as well as the example is correct. B The statement as well as the example is incorrect. C The statement is correct, but the example is incorrect. D The statement is incorrect, but the example is correct.

THE FUTURE? ? California to collide with Alaska LA to join Francisco Pacific ocean becomes smaller Mediterranean sea to disappear San Himalayas becoming higher Horn of Africa drifting away Atlantic ocean wider Eventually – ONE Earth

Was the Durban. Tremor a sign of a new African continent forming? 2016 -02 -10 - Louzel Lombard Cape Town - In only a few million years, Planet Earth might be one continent richer, as the first signs of a continental split was seen in the past weekend's Durban. Tremor. The Durban quake, which measured 3. 1 on the Richter Scale, could have been a movement that will see this city and the whole eastern side of the African continent split from the current African continent. This because the Somali Plate – which has a fault line stretching from the East African Rift southwards down through South Africa and exiting through Durban – is slowly breaking away from its larger African, or Nubian Plate.

What happened here?

What is folding? Forces push rock layers together Rocks bend into folds

Syncline and Anticline Syncline Downwards bend Anticline upwards bend Anticline Sincline Anticline

What is Faulting? F F O O R R C C E E • Strong pressure applied to rocks • Rocks break along faults

Types of faults Tension Compression Lateral forces
