Layers
Name the 4 layers of the Earth we are studying from outermost to innermost.
Crust, mantle, outer core, inner core
Draw arrows showing the directions of a divergent boundary
Away from each other.
Define Volcano
an opening in the earth's crust through which lava, ash and gases can escape
The most damage on the surface of an earthquake occurs at the
epicenter
Which 2 layers are solid.
Crust and inner core.
This layer is made of solid iron and nickel
Inner core
Draw arrows showing transform fault boundary. Also called slip or sliding boundary.
Up and down.
Violent eruptions occur at this type of volcano such as Mount St. Helens
Composite
Where is the focus located and why does it happen there
The focus is located along a fault or boudary where 2 plates catch and then snap or brake- a- part.
It is located in the crust.
Which 2 layers are not solid
Mantle and inner core
This layer is the thinnest and made of rock
The crust
Draw arrows showing a convergent boundary
Toward each other.
This type of volcano has gentle flowing lava and an example of these are the Hawaiian Islands
Shield Volcanoes
These types of waves generate from the focus and cause damage and after shocks
Seismic Waves
A divergent boundary causes which types of landforms
Can cause rift valleys , but also mountains in the ocean
Which layer is the thickest and largest
The mantle
Which type of boundary causes a subduction zone and what happens to the 2 plates
Convergent boundary when one plate slides under the other.
Most common type of volcano
Shield volcano
The scale to measure earthquakes is called the _____ scale
Richter
Transform fault boundaries cause
Earthquakes
This layer is made of molten magma
The mantle
A convergent boundary causes which type of landform
Mountains
Over 60% of the earth's volcanoes are located along __________
Ring of Fire
The most famous fault is called the ________________ and goes from Mexico to oregon
San Andres Fault
Name the 3 main types of rocks and next to each write what activity forms each type
Igneous- Melting and cooling
Sedimentary- compaction and Cementation...weathering, erosion
Metamorphic- extreme heat and pressure
