This main type of rock forms under heat and pressure.
What is metamorphic?
This plate tectonic anomaly forms island chains such as the Hawaiian Islands.
What is a hot spot?
In 2011, this sliding boundary produced a 6.3 magnitude earthquake that shook Christchurch New Zealand.
What is transform?
This fault (boundary) is characterized by folded mountains, plateaus and earthquakes.
What is a convergent boundary?
Ocean plates will always do this when converging with continental plates.
What is sink?
Layer G is also known as this formation.
What is an intrusion?
This type of chemical sedimentary rock forms plant and animal debris.
What is coal?
Lava escapes this landform in the ocean when two ocean plates diverge.
What is an mid-ocean ridge?
On February 6, 2023 a magnitude 7.8 slip-strike form of this tectonic phenomenon occurred in southern Turkey, killing over 55,000 people.
What is an earthquake?
The mid atlantic fault involves two of thsi type of crust. They are diverging away from each other creating volcanoes, earthquakes and mid-ocean ridges.
What is oceanic?
What are convection?
The youngest layer:
What is layer I?
This magnesium poor-sedimentary rock deposit is more than 3,000 feet thick in some parts of Illinois.
What is limestone?
When these two plates of crust converge, no magma reaches the surface to form a volcano.
What are continental?
These are created when ocean crusts subduct. Pressure at the bottom of the deepest one is more than 1,071 times the standard atmospheric pressure at sea level.
What are trenches?
The eastern portion of the African plate is currently splitting into what some geologists refer to as the Nubian and Somali plates, creating this tectonic landform.
What is a rift valley?
As slow moving mantle rock sinks towards the core of the Earth, its density will become this and slowly rise towards the crust.
What is less?
The oldest layer.
On April 30, 2018, the Puʻu ʻŌʻō cone of the Kīlauea volcano collapsed, triggering an eruption that spewed this material up to 26,000 gallons per second for 4 months.
What is lava?
As the Juan de Fuca plate subducts under the North American plate, ocean crust melts and forms this landform.
What is a volcano?
The April 2015 this boundary produced the Nepal earthquake (also known as the Gorkha earthquake) which killed 8,962 people in Nepal and injured 21,952.
What is convergent?
The subducion of the Indian Plate beneath the Sunda Plate formed the volcanic arc in western Indonesia, one of the most active areas on the planet with a long history of powerful eruptions and these seismic events.
What are earthquakes?
So long as the temperature of the core remains ____, slow-moving mantle rock will continue to circulate.
What is hot?
This law states that in undeformed stratigraphic sequences, the oldest strata will lie at the bottom of the sequence.
What is the Law of Superposition?
The biggest coal deposit by volume is the Powder River Basin in this western state, which the USGS estimated to have 1.07 trillion short tons.
What is Wyoming?
80% of the world's volcanoes are located along these zones.
What are subduction zones?
This rock formation is created underground when an earthquake occurs.
What is a fault?
The subduction of these two plates along the great Alaska-Aleutian Megathrust comprise ~2,500 miles of the "Ring of Fire" where ongoing subduction gives rise to arcs of active volcanoes and the largest earthquakes in the world.
What are the North American and Pacfic plate?
Convection currents in the mantle are creating this type of boundary:
What is divergent?
What 'D' in the diagram is referring to.
What is a fault?
