-
alluvion
gradual formation of new land, by recession of the sea or deposit of sediment
-
desertification
the gradual transformation of habitable land into desert; is usually caused by climate change or by destructive use of the land
-
diastrophism
the process of deformation that produces continents and ocean basins in the earth's crust
-
eating away, eroding, erosion, wearing, wearing away
(geology) the mechanical process of wearing or grinding something down (as by particles washing over it)
-
fold, folding
a geological process that causes a bend in a stratum of rock
-
glaciation
the process of covering the earth with glaciers or masses of ice
-
intrusion
the forcing of molten rock into fissures or between strata of an earlier rock formation
-
metamorphism
change in the structure of rock by natural agencies such as pressure or heat or introduction of new chemical substances
-
orogeny
the process of mountain formation (especially by the upward displacement of the earth's crust)
-
stratification
forming or depositing in layers
-
subduction
a geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate
-
chatter mark
marks on a glaciated rock caused by the movement of a glacier
-
ablation
the erosive process that reduces the size of glaciers
-
abrasion, attrition, corrasion, detrition
erosion by friction
-
anamorphism
metamorphism that occurs deep under the earth's surface; changes simple minerals into complex minerals
-
beach erosion
the erosion of beaches
-
epigenesis
a geological change in the mineral content of rock after the rock has formed
-
foliation
(geology) the arrangement of leaflike layers in a rock
-
Riss glaciation
the next-to-last Pleistocene glaciation in the Alps and the deposits laid down at that time
-
Saale glaciation
the next-to-last Pleistocene glaciation in northern Europe and the deposits laid down at that time
-
Wolstonian glaciation
the next-to-last Pleistocene glaciation in Britain and the deposits laid down at that time
-
deflation
(geology) the erosion of soil as a consequence of sand and dust and loose rocks being removed by the wind
-
katamorphism
metamorphism that occurs at or near the earth's surface; breaks down complex minerals into simpler ones
-
planation
the process of erosion whereby a level surface is produced
-
soil erosion
the washing away of soil by the flow of water
