Earths Layers
The outermost and thinnest layer of the Earth
Crust
This layer of the Earth is broken into pieces called tectonic plates
lithosphere
the plate boundary where 2 plates collide with each other
convergent boundary
The type of plate boundary that creates new oceanic crust
divergent boundary
What forces have acted on the Appalachian Mountains to give them the rounded shape?
A. weathering B. volcanic eruption C. earthquakes D. tsunamis
weathering
The thickest layer of the Earth located between the crust and the outer core
mantle
The 2 types of tectonic plates are
oceanic and continental
The plate boundary where 2 plates slide past each other
transform boundary
The process of new oceanic crust forming is
sea-floor spreading
Some sedimentary rocks were formed from sediments deposited into oceans millions of years ago. Which process was most responsible for depositing the sediments?
A. elevation B. erosion C. eruption D. evaporation
what is erosion B
When the crust shifts, which typically results?
earthquakes
Newly formed oceanic crust occurs at which type of plate boundary?
divergent boundary
The plate boundary where 2 plates pull apart from each other
divergent boundary
mid ocean ridge
How can a metamorphic rock change into a sedimentary rock?
where is convection currents being created and name both layers
mantle; anthosphere
Plate tectonics provided evidence to support what theory that could not be explained before
Continental Drift
The plate boundary where mountains are formed
convergent boundary
Underwater volcanos will sometimes create large waves that are known as
tsunamis
the scientific results that support a theory are
evidence
The layer of the Earth that contains the crust and uppermost part of the mantle
lithosphere
Plate tectonics cause changes to the geological features of the Earth. True or False
True
The plate boundary such as the San Andreas Fault in California that often produces Earthquakes
transform boundaries
The process where old crust is recycled by being pushed under another plate into the mantle is called
subduction
According to Wegener, what evidence supports the theory of continental drift in which the continents were all together as one landmass?
fossils from other area appears on different continents.
continents fit like puzzle
