C2 Level Wordlist

the scientific study of the Earth's lithosphere and the processes that shape its structure, including the movement of tectonic plates, earthquakes, and volcanic activity

Ex: International collaboration is common in tectonics research , fostering a global effort to uncover the mysteries of Earth 's lithospheric behavior .
plate [noun]

a large, rigid section of the Earth's lithosphere that moves, leading to geological activity like earthquakes and volcanic eruptions

Ex:
fissure [noun]

(in geology) a narrow break or crack that partially divides a rock or surface without completely separating it

Ex: The tectonic plates pulled apart , causing a new fissure to emerge in the earth 's surface .

a geological process where one tectonic plate moves under another and sinks into the Earth's mantle

Ex: Subduction zones are often associated with deep ocean trenches , such as the Peru-Chile Trench along the western coast of South America .
isostasy [noun]

the gravitational balance between Earth's rigid lithosphere and the underlying, semi-fluid asthenosphere, influencing variations in surface elevation

Ex:

the Earth's rigid outer layer, made up of the crust and upper mantle, and divided into tectonic plates

Ex: The lithosphere contains diverse geological features , from vast mountain ranges to deep ocean trenches .

a layer of semi-fluid rock beneath the Earth's crust that allows tectonic plates to move

Ex:
karst [noun]

a landscape formed from the dissolution of soluble rocks, characterized by sinkholes, caves, and underground drainage systems

Ex:
orogeny [noun]

the geological process of mountain building, usually occurring due to the collision or convergence of tectonic plates

Ex: The Alps in Europe are a consequence of the collision between the African and Eurasian plates , demonstrating orogeny .
geode [noun]

a hollow rock with a cavity inside, lined with crystals or mineral material, formed through natural processes and often valued for its aesthetic qualities

Ex: Explorers discovered a large geode in a limestone cave , revealing intricate crystal formations within its hollow cavity .

a volcanic rock that often contains diamonds, formed during explosive eruptions from the Earth's mantle, and is of particular interest in diamond exploration and mining

Ex:

the geological process involving the expansion and movement of glaciers, shaping landscapes through erosion, deposition, and the formation of distinctive glacial landforms

Ex: Glaciation in the Pleistocene epoch left behind moraines , creating undulating terrain across many regions .
moraine [noun]

a deposit of rocks, sediment, and glacial material left by a moving glacier, forming distinctive landforms along its edges or terminus

Ex: As the glacier melted , it left behind a series of recessional moraines , documenting its gradual retreat .
drumlin [noun]

a streamlined, elongated hill formed by glacial action, with a teardrop shape and the steeper end facing the direction of ice movement

Ex: Researchers studied the orientation of drumlins to reconstruct the flow direction of the ancient ice sheet .
caldera [noun]

a large, basin-shaped volcanic crater formed by the collapse of a volcano after a massive eruption

Ex:

the physical and chemical changes occurring in sediments between their deposition and their consolidation into sedimentary rock

Ex: The process of diagenesis can transform loose sediment into solid rock , such as sandstone , shale , or limestone , over geological time scales .

a complete change in the form and structure of a rock as a result of heat and pressure

Ex: Geologists study metamorphism to understand the processes that shape the Earth 's interior over millions of years .

the process by which particles settle out of a liquid or gas due to gravity, forming a sediment layer

Ex: Sedimentation in pipelines can reduce flow rates and efficiency .
faulting [noun]

the movement or displacement along a fracture in the Earth's crust, resulting from tectonic forces, which can lead to earthquakes

Ex: The faulting process can disrupt underground utilities like pipelines .
aquifer [noun]

a layer of rock or sediment that stores and transmits groundwater

Ex: Groundwater levels in the aquifer dropped during the drought .

a hard lump or mass formed in sedimentary rock by natural cementing processes

Ex: The size and shape of concretions provide clues about ancient environments .
pluton [noun]

a large body of igneous rock formed beneath the Earth's surface from magma that has cooled and solidified

Ex: Plutons can create significant uplift and deformation in the Earth 's crust .
folding [noun]

(in geology) the bending or deformation of rock layers due to compressional forces

Ex:
lahar [noun]

a fast-moving mixture of volcanic ash, debris, and water

Ex: The construction of bridges considers the potential impact of lahars on river crossings .

the process during which a building or piece of land sinks to a lower level or to the ground

Ex: Engineers monitored the area for subsidence to ensure the stability of the newly constructed dam .

(geology) the injection of magma into existing rock formations underground

Ex: Intrusions often exhibit distinct mineral compositions .
matrix [noun]

(geology) the fine-grained material surrounding larger rock fragments or grains within a sedimentary rock

Ex: The limestone matrix contained fossil fragments .
igneous [adjective]

(of rock) formed from cooled magma or lava

Ex: Geologists study igneous structures to understand Earth 's geological history .
