C2 Ordlista - Geologi

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

tektonik

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

plattektonik

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

spricka

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

subduktion

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

isostasi

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

litosfären

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

astenosfären

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

karst

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

orogenesis

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

geode

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

kimberlit

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

istid

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

morän

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

drumlin

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

kalderan

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

diagenes

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

metamorfism (geologi)

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

avlagring

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

felrörelse

a layer of rock or sediment that stores and transmits groundwater

akvifer

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

hård, kompakt massa av mineraler som bildas i bergarter

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

batholith

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

böjning i berglager som orsakas av jordens tryck

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

destruktivt lerflöde på sluttningarna av en vulkan

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

sättningar

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

magmatisk intrång

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

fint sediment som omger större fragment i en sten

(of rock) formed from cooled magma or lava

magmatisk bergart
