Igneous Rocks
Volcanoes
Seafloor Spreading
Layers of the Earth
Earthquakes
100
Type of rock that is made from high silica content with quarts and both feldspars present.
What is Felsic or light colors
100
Composite or stratovolcanoes are found at this type of boundary.
What are subduction zones of convergent boundaries?
100
At this point of the ocean is the deepest and the coldest. It also contains a thick layer of sediment due to the amount of time it has had to build up.
What are the trenches of the ocean?
100
This layer of the Earth rides another layer like a boat on water.
What is the lithosphere riding the asthenosphere?
100
The majority of earthquakes happen at this area.
What are boundaries?
200
Type of rock that is made from middle silica content with light and dark colored minerals present.
What is Intermidiate coloring?
200
Shield Volcanoes are found at this type of boundary
What are divergent boundaries or hot spots?
200
At this point of the ocean, it is the hottest and creates new seafloor. Also known as a divergent boundary. Has a very thin layer of sediment due to the little amount of time the seafloor has been there.
What are the Mid-Ocean Ridges?
200
This is the range of the depth of oceanic crust and the density of oceanic crust.
What is 5-10km. Also it has a density of 2.9g/cm2
200
These kinds of waves arrive second and cause the most damage.
What are S waves?
300
Type of rock that is made from lower silica content, rich in iron and magnesium with plagioclase feldspar, biotite, amphibole, ryrooxene and olivine present.
What is Mafic or dark colors?
300
Cinder Cone volcanoes are found at this type of boundary.
What is near convergent boundaries?
300
The range of age of the seafloor.
What is 0-180 million years of age?
300
The range of depth for continental crust, and the density of continental crust.
What is 25-40km, and has a density of 2.7g/cm2
300
This is how earthquakes are determined where the epicenter is and how powerful they are.
What is by triangulating three stations by reading the seismograms of the earthquake?
400
Classifying rocks with the texture of coarse.
What are intrusive rocks?
400
This volcano is the most explosive and are abundant in the Ring of Fire.
What are the composite or stratovolcanoes?
400
The system that was used to find the topography of the ocean floor. This system/method is where a sound is send to the bottom of the ocean and then bounces back up and the time is divided by 2 to find the depth of the ocean floor.
What is the SONAR system?
400
This increases the deeper you go into the Earth.
What is pressure?
400
The three forces that act on rock.
What are compression (squeezes rocks together), tension (pulls rock apart), or shear (occur when rocks are moving sideways past one another)
500
Classifying rocks with the texture of fine, glassy, vesicular, or porphyritic.
What are extrusive rocks?
500
This type of volcano is the most common and the smallest of the volcanoes.
What are the Cinder Cone volcanoes?
500
Seafloor is destroyed at this type of boundary/area.
What are convergent boundaries/trenches?
500
Only layer of the Earth that is liquid.
What is the outer core?
500
The place along a fault below the ground where the rocks break.
What is the focus?
