Coast Formation
Weathering
the process of breaking down rocks into smaller pieces
Wind
Rocks blown through air
Muddy Shore Characteristics
Little wave action, little erosion, little to no slope, and water moves very slow
Where do They Grow
Brackish wetlands, saline wetlands
White Mangrove Characteristics
Sand roots, no visible roots above water, broad yellow-green leaves with greenish white flowers
Erosion
the process of moving sediment/rocks to another location
Water
Water moving Rock
Estuaries Charateristics
Diluted sheltered, muddy substrate, slow flow of water, no water and erosion
Relation to Equator
30 degrees of the Equator
Mangroves Relation With Salt
Mangroves extrude salt by excreting it through leaves or sequestering it in bark
Sedimentation
the process of depositing materials (sediment/rocks) in a new location where they accumulate
Gravity
Landslides/ Earthquakes
Delta Formation
The mouth of the river exits, low-lying triangular areas form by the deposition of sediments, over a long period of time, the sediments accumulate to form a wide, fan-shaped structure called "Deltas"
Black Mangrove Characteristics
Live on higher ground than red mangroves, horizontal roots, root-like pencil-shaped, excrete salt by glands at base
Pneumatophores
Aerating roots that exit the soil to allow trees to exchange gases in waterlogged soil
How Chemical Weathering Occurs
Results from exposure from acid rain, water, or oxygen
Ice
Glaciers move and pick up sediments
Delta Characteristics
High sedimentation and low water flow
Conditions for Formation
Brackish water, low competition, limit water loss
Why Are They are Important to Humans and Ecosystems
Reduce wave energy, buildup sediments under roots, reducing turbidity of water for corals and seagrass
Physical weathering
Rocks get smaller due to physical forces like heating, cooling, ice, and waves
Particle Size and Erosion Relation
The larger the particles, the shorter distance they travel and the faster they deposit. When water begins to slow down, bigger pieces will form sediments while smaller pieces may stay suspended. The smaller the particle, the longer they take to come out of solution.
Differentation Between Delta and Estuaries
Deltas push the sediments out of the river, while estuaries hold the sediments in the river.
Viviparous Reproduction
Mangrove makes flowers, fertilized to form seeds, develop into propagules which grow while attached to parent plant, then drops from parent and floats horizontally for 40 days, maturing further then floats vertically with appropriate
Carbon Dioxide Relation
May be most effective carbon sinks of any natural ecosystem
