Dynamic Earth

What is Pangea?

• a supercontinent that began to break apart approximately 200 million years ago

• long, narrow mountain range on the ocean floor, formed by magma at divergent plate boundaries

• all continents were once connected in a single landmass that slowly drifted apart 200 mya

• a deep underwater trough created by one plate subducting under another plage

What is Continental Drift

• a supercontinent that began to break apart approximately 200 million years ago

• long, narrow mountain range on the ocean floor, formed by magma at divergent plate boundaries

• all continents were once connected in a single landmass that slowly drifted apart 200 mya

• a deep underwater trough created by one plate subducting under another plage

What do scientists use to support continental drift?

• rocks & minerals

• fossils & rocks

• fossils & mid ocean ridges

• mid ocean ridges & minerals

What is the crust?

• A large slab of the earth's crust

• Where plates meet

• The thin outer layer of the earth, made of solid rock

• The solid centre of the earth

What is the mantle?

• A large slab of the earth's crust

• Found underneath the crust

• The thin outer layer of the earth

• The solid centre of the earth

? cause the plates to move under the earth
