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

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

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

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

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

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

lithosphère, couche rigide externe de la Terre
a layer of semi-fluid rock beneath the Earth's crust that allows tectonic plates to move

asthénosphère, couche semi-fluide sous la croûte terrestre
a landscape formed from the dissolution of soluble rocks, characterized by sinkholes, caves, and underground drainage systems

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

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

géode, caverne cristalline
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

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

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

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

drumlin, colline allongée formée par l'action glaciaire
a large, basin-shaped volcanic crater formed by the collapse of a volcano after a massive eruption

caldeira, cratère volcanique
the physical and chemical changes occurring in sediments between their deposition and their consolidation into sedimentary rock

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

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

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

faillage, fracturation
a layer of rock or sediment that stores and transmits groundwater

aquifère, nappe phréatique
a hard lump or mass formed in sedimentary rock by natural cementing processes

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

pluton, massif plutonique
(in geology) the bending or deformation of rock layers due to compressional forces

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

un lahar, une coulée de boue volcanique
the process during which a building or piece of land sinks to a lower level or to the ground

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

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

matrice, matrice
(of rock) formed from cooled magma or lava

igné, volcanique
