Plates on the move
Who is the German Geologist that came up with the idea of Continental Drift?
Who is... Alfred Wegener
Downward movement of the edge of a tectonic plates into the mantle.
What is... Subduction
This type of boundary occurs when 2 plates run directly into each other.
What is... Convergent Boundary
This type of volcano has very fluid magma, eruption are very mild, and is shaped like a long hill.
What is... Shield Volcano
Wegener noticed these 2 continents looked like they would fit together like a puzzle.
What is... Africa & South America
What is... Oceanic Crust
This type of boundary occurs when 2 plates move AWAY from each other.
What is... Divergent Boundary
This type of volcano has very thick magma, eruptions are very violent and shapes the volcano like a large mountain.
What is... Composite Volcano
The Earth's crust is broken up into many of these
What is... Tectonic Plates
This type of crust is LESS dense and will rise over top of the other one when they meet.
What is... Continental Crust
This type of boundary occurs when 2 plates slide past each other.
What is... Transform Boundary
This type of volcano also has very thick magma and violent eruptions. These are usually identified by the large calderas in the middle.
What is... Cinder Cone Volcano
What kind of currents in the mantle cause the plates to move?
What is... Convection
This layer of crust is made up of the crust and top part of the mantle. It is very brittle and broken up into many "plates"
What is... The Lithosphere
What type of landform is created in the ocean between 2 divergent boundaries.
What is... Mid-Ocean Ridge
This landform is created when the more dense oceanic plate subducts under the less dense plate. These are some of the deepest areas of the ocean.
What is... a Trench
Where was Alfred Wegener born?
Where is... Berlin Germany
This layer of crust is made up of the top part of the mantle. It is very fluid and the plates float on top of it.
What is... The Asthenosphere
This type of landform is created when a convergent boundary cause crust to rise up.
What is... Mountains or Volcanoes
What is... Pacific Plate
Some of the youngest crust in the world is located near these geologic features.
What is... Mid-Ocean Ridge
