Rocks
Name the three types of rocks.
Igneous, Metamorphic, and Sedimentary
What is the definition of Geology?
The study of the Earth, its history, and the processes that act on it.
What is the layer of rock that forms Earth's outer surface called?
The Crust
What do transform boundaries create?
They create earthquakes by grinding past each other and releasing energy in the form of seismic waves.
What was the name of the super continent 450 million years ago?
Pangea
What processes create metamorphic rocks?
Extreme heat and pressure.
Describe what deposition is.
Process in which sediment is laid down in new locations.
What are the circular currents in the mantle caused by the magma being heated by the core off the Earth called?
Convection Currents
What movement does a divergent boundary make?
Two tectonic plates moving away from each other (diverging)
Which area of river is more likely to erode faster: Where there is a fast current or slow current?
Fast current
Which type of rock can have fossils in it?
Sedimentary
Describe what erosion is.
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another
Describe what weathering is.
The breaking down of rocks and other materials on the Earth's surface.
What is created when two continental plates converge?
Mountain ranges (this is how Mt. Everest grows a little each year)
What is the Ring of Fire?
The Ring of Fire is a string of volcanoes and earthquake zones around the Pacific Ocean where different tectonic plates meet.
The longer an igneous rock takes to cool, the ___________ the crystal size.
larger
What are the vibrations that travel through Earth carrying the energy released during an earthquake called?
Seismic Waves
What is the lithosphere?
A rigid layer made up of the uppermost part of the mantle and the crust.
What causes tectonic plates to move?
Hint: It has something to do with the asthenosphere.
The sinking of the lithosphere into the asthenosphere.
Describe the Theory of Continental Drift
The theory that all of the continents were originally all together and then moved apart due to tectonic plate activity.
Some sedimentary rocks will fizz when a drop of acid is placed on it. What mineral do these rocks contain that causes this reaction?
Calcite
What is the Principle/Law of Superposition?
A theory that says sedimentary rocks on the bottom are older than rocks on the top.
What is the asthenosphere?
The soft layer of the mantle on which the lithosphere floats.
Describe what a subduction zone is.
An area where two plates meet and one moves under the other. This is where the subducted plate melts.
When is Ms. Arch's last day?
Friday, March 14th (unless baby comes early)
