Tectonic Plates
What is plate tectonics?
Plate tectonics is the theory that the plates of the earth's crust are slowly moving
What is a sediment?
A sediment is small bits and pieces of rocks (similar to pebbles)
Define: Metamorphic Rock
A rock formed by heat and/or pressure
What is magma?
Magma is melted rocks that have taken on a liquid form
Name the 4 layers of the Earth
The crust, the mantle, the inner core and the outer core
Plate tectonics is directly responsible for and drives the...?
The rock cycles
A compacted sedimentary rock is also known as a
Clastic Sedimentary Rock
What is contact metamorphism caused by?
Heat
What is an intrusive igneous rock?
An igneous rock that has cooled below earths surface.
The largest section of the mantle is known as the...?
The lower mantle
Name 3 catastrophes that are caused by the movement of tectonic plates
Double points: Explain how the movement of the plates cause each event.
Earthquakes, volcanoes, and tsunamis
Earthquakes are caused by the opening. shifting and collision of the plates, volcanoes are caused by the movement of the asthenosphere and tsunamis are caused by underwater earthquakes and volcanoes
What is a bioclastic rock?
A rock that contains organic matter such as fossils.
What is regional metamorphism caused by?
Pressure
What is the difference between lava and magma?
Lava is magma that is found on the surface of the earth, magma is found below the surface.
The crust and the upper part of the mantle is known as the...?
The lithosphere
What are plate boundaries?
The place where tectonic plates meet
Define: Lithification
Lithification is the process by which sediments are compacted and cemented together to make sedimentary rocks
Metamorphic rocks that have visible sheets or layers are known as?
Foliated Metamorphic Rocks
Igneous Rocks that form from lava are known as...?
The moving layer of the mantle is known as the....
The asthenosphere
What are the three types of plate boundaries?
Convergent Boundaries, Divergent Boundaries, and Transform Boundaries
What is a evaporite?
A sedimentary rock formed when water evaporates from a group of dissolved minerals
What is a non-foliated metamorphic rock?
A metamorphic rock that does not have regular or visible layers.
Igneous rocks can be identified by scientists based on what three factors?
1) The type of minerals it contains
2) The texture of the rock
3) The color of the rock
Plate tectonics is a combined effort between which two layers?
The lithosphere and the asthenosphere
