Detrital
Detritus is particles of rock derived from pre-existing rock through processes of weathering and erosion
Got it
rock cycle
The rock cycle is a basic concept in geology that describes the time-consuming transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous
Got it
weathering
Weathering is the breaking down of rocks, soil and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, waters and biological organisms
Got it
sand dunes
In physical geography, a dune is a hill of sand built by wind or the flow of water
Got it
headland
A headland is a coastal landform, a point of land usually high and often with a sheer drop, that extends out into a body of water
Got it
beach
A beach is a landform along a body of water
Got it
barrier island
Barrier islands are coastal landforms and a type of dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast
Got it
Thermal expansion
Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through heat transfer
Got it
Deposition
In the law of the United States, a deposition is the out-of-court oral testimony of a witness that is reduced to writing for later use in court or for discovery purposes
Got it
faults
In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock mass movement
Got it
fracture
A bone fracture is a medical condition in which there is a damage in the continuity of the bone

The rock cycle is a basic concept in geology that describes the time-consuming transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous
Detrital
Detritus is particles of rock derived from pre-existing rock through processes of weathering and erosion
secondary rocks
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water
fold
A geological fold occurs when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation
meanders
A meander, in general, is a bend in a sinuous watercourse or river
river
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river
moraine
A moraine is any glacially formed accumulation of unconsolidated glacial debris that occurs in both currently and formerly glaciated regions on Earth , through geomorphological processes
Surface water
Surface water is water on the surface of the planet such as in a river, lake, wetland, or ocean
Base level
The base level of a river or stream is the lowest point to which it can flow, often referred to as the 'mouth of the river'
metamorphic
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form"
ductile deformation
In Earth science, as opposed to Materials Science, Ductility refers to the capacity of a rock to deform to large strains without macroscopic fracturing
minerals
A mineral is a naturally occurring chemical compound
erosion
In earth science, erosion is the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location
