Earth Layers
The thinnest layer of the earth
Most earthquakes occur along
Plate boundaries OR the Ring of Fire
This type of rock forms from compacted & cemented sediments
Sedimentary
Type of weathering that causes a new substance to form
Chemical
Type of front that is associated with Thunderstorms and severe weather
Cold
The solid layer made of iron and nickel
Inner core
The number of seismograms needed to determine an earthquake's epicenter?
3
This category of igneous rock can produce large crystals
Instrusive (inside the earth)
Location on a meander, where the most erosion occurs
Cutbank
An airmass with an identifier of cP would bring this type of air
dry and cold
This layer is broken into tectonic plates
Lithosphere
The numeric scale used to rank an earthquake's magnitude (energy expressed)
Ricther Scale
A fine grained igneous rock cools where?
Quickly above ground
This agent (force) of erosion is most responsible for shaping the Earth's surface
Water
Atmospheric pressure ______ with an increase in altitude
The tectonic plates move on top of this layer
Asthenosphere
This deep feature forms at subduction zones
Trench
Type of volcano that forms @ divergent boundaries from the melting of oceanic crust
Shield
Type of structure built perpendicular to the shoreline for the purpose of building up a beach
groin
List 3 greenhouse gasses:
Water vapor, carbon dioxide, methane, nitrous oxides, ozone, CFC's
Plate movement occurs because of:
convection in the mantle
What is the difference between a convergent boundary & a subduction zone?
A convergent boundary occurs when 2 tectonic plates collide. A subduction zone is a TYPE of convergent boundary that forms when ocean and continental crust meet.
The type of volcano that forms when an oceanic and continental plate collide
Stratovolcano or Composite cone
A longshore current is:
a curent that flows parallel to the shoreline due to wave refraction.
List 4 consequences of climate change:
-Increase in flooding & droughts
-Decrease in crop yield
-Increase in the intensity of hurricanes
-Increase in allergies & heat-related diseases/deaths
-Decrease in forests & increase in tropical diseases farther away from the equator
-Decrease in biodiversity
-Rise in sea level & increase in coastal erosion
