What most often causes the formation of rift valleys along the ocean floor?
Convergent plates
Divergent plates
Transform fault
Thermal vent
The mountains in Colorado contain many foliated metamorphic rocks. What can most likely be concluded about the formation of these mountains?
Ocean tectonic plates rose above the denser continental plates, forming mountains containing layers of metamorphic rocks.
Crystalline structures within the land in the mountains produced metamorphic rocks that formed various layers.
The mountains were formed by the collision of tectonic plates causing sedimentary rocks to compress under extreme heat and them minerals to line up forming layers.
Sediments deposited during mountain building became trapped and solidified in mountains containing layers of metamorphic rock.
Which will most likely form when movement along a plate boundary forces a land mass to be pulled apart?
A convergent boundary
A Mountain Range
A Continental Rift
A Volcanic Island
Geologic data for recent California earthquakes, by location and magnitude, are shown in the map. Based on this data, predict where an earthquake is LEAST likely to occur in the near future and give a logical reason why this is.
Location C, because all of the past earthquakes in that location have been very minor.
Location D, because there are the fewest fault lines here as well as the fewest earthquakes.
Location B, because it is a heavily populated area and precautions have been taken to guard against earthquakes.
Location A, because of the recent frequency of earthquakes in this location, there will not be anymore for a long time.
Crack in Earth's crust that occurs when stress is applied.
fault
earthquake
boundary

Convection currents the effect the movement of the earth's plates are located in what layer?
crust
asthenosphere
lithosphere
upper mantle
What state of matter is the inner core of the earth considered to be?
solid
liquid
gas
high plasticity liquid
The asthensophere is found in the
lithosphere
upper mantle
upper lower mantle
upper outer core
Oceanic plates are considered to be thinner, more dense plates compared to the thicker, less dense continental plates. What might cause this?
Ocean plates are located under both atmospheric and water pressure
Oceanic plates are closer to the core, hotter and melt to be thinner
Oceanic plates consist of many fossils that require pressure to form
Oceanic plates have water in them and allow more space between molecules.

Pangea
Mid Atlantic Ridge
Wegener's Continent
