Tectonic Plates
A convergent boundary is when 2 tectonic plates
move towards eachother
True or False? Rocks can break apart into sediments
true
What rises up from underground that makes mid Ocean ridges
Magma
Where was Alfred Wegener born?
Germany
Transform Boundaries can cause
Earthquakes to occur
True or false? rocks cannot change from sediments to metamorphic rocks
false
Where would you expect to find the oldest ocean crust?
Furthest from the continental crust
Who came up with this theory?
Alfred Wegner
Where do earthquakes occur most frequently
along plate boundaries
In order for sediments to become sedimentary rock, the best process they must go through is
sediments are pressed and glued together over long periods of geological time
What forms when seafloor spreading occurs
Mid Ocean ridges
Where was Alfred Wegeners last expedition?
Greenland
At what kind of plate boundary is the new oceanic lithosphere created
divergent plate boundary
Where are metamorphic rocks formed
deep underground
What happens to the continents and Ocean over time they create what?
Mid Ocean Ridges
Evidence to support continental drift
The same kind of fossils are found in South America and Africa
The same kind of rock layers are found in North America, Europe, And Africa
What is the plate tectonics theory state?
Earth's surface is made up of tectonic plates that have moved over time
What would most likely provide enough heat and pressure to change a sedimentary rock into a metamorphic rock
Subduction
Which plate boundary can cause mid Ocean ridges
Divergent plate boundaries
What's continental drift?
The continents were once one large landmass that has moved over time
