Weathering and Sediments
Exfoliation, abrasion, and frost wedging are this kind of weathering.
What is mechanical weathering?
Any chemical or biochemical sedimentary rock that is made of calcite.
What is limestone?
This type of stream forms where the topography is steep.
What is a straight stream?
The main force that shapes coasts.
What are waves?
What is silt?
This is the depositional environment for both arkoses and breccias.
What is an alluvial fan?
The type of drainage pattern that looks like branches of a tree.
What is dendritic drainage?
This type of continental margin is characterized by a narrow, steep continental shelf.
What is an active margin?
What is hydrolysis?
Lithification of sediment to form a sedimentary rock involves these two processes.
What are compaction and cementation?
These types of streams do more horizontal (side to side) erosion rather than vertical erosion
What are meandering streams?
These coasts are formed when glacial valleys are flooded by rising sea level.
What is a fjord?
Sediment that is made up of mostly grains of this mineral is mature.
What is quartz?
This type of rock forms when minerals that are dissolved in water come out of solution due to changes in temperature, pressure, ph, etc.
What is a chemical sedimentary rock?
This type of sediment is deposited on the floodplain of a river.
What is silt and clay?
Basically an overgrown sandbar that borders some passive margin coastlines.
What is a barrier island?
Solid pieces of pre-existing rock formed mostly by mechanical weathering
What is Clastic sediment?
The type of rock formed when living things extract minerals to make their shells or other body parts, and those remains accumulate after they die.
What is a biochemical sedimentary rock?
This elevated area that borders a stream can form naturally during a flood or be man-made to prevent flooding.
What is a levee?
This "current" is caused by the fact that waves don't wash ashore perfectly parallel to the shoreline.
What is longshore current?
