Coasts EQ1 Flashcards
lithology
the study of the general physical characteristics of rocks
morphology
the study of the geological structure, shape, or form of a feature
submergent coast
stretch of coastline that is inundated by the sea due to eustatic or isostatic changes (e.g. Dalmatian coast)
emergent coast
stretch of coastline that has been exposed by receding sea levels or isotactic uplift/ rebound (e.g. Haff coast)
concordant
rock structure/ lithology runs parallel to the coast (e.g. creates coves)
discordant
rock lithology runs perpendicular to the coast creating bands of alternate rock types (e.g. headlands and bays)
littoral zone
the wider coastal zone including adjacent land areas and shallow parts of the sea just offshore
cliff profile
the height and angle of a cliff face as well as its features such as wave-cut notches or changes in slope angle
sub- aerial processes
processes acting on cliffs; weathering, mass movement and surface runoff
coastal accretion
the deposition of sediment at the coast and the seaward growth of the coastline, creating new land. it often involves sediment deposition bring stabilised by vegetation
geological structure
the arrangement of rocks in three dimensions; strata, deformation, and faulting
unconsolidated sediment
materials such as sand, gravel, clay, and silt that has not been compacted and cemented to become sedimentary rock (it has not undergone the process of lithification) and so it is loose and easily eroded
hydrological cycle
the water cycle if the journey water takes as it moves from the land to the sky and back again. it follows a cycle of evaporation, condensation, and precipitation
haff
a long shallow lagoon separated from the open sea by a narrow sandbar or barrier beach (as on the Baltic coast of Germany)
Dalmation
numerous elongated islands lying just offshore and parallel to the mainland
