what are the 3 primary reasons that coasts are greta places to live in / why people settled along
coasts? correct answers agriculture, mild climate, access to sea for trade
how did the stabilization of sea level around 7,000 years ago promote people to settle coastal
areas? correct answers stable coastal landscape, fertile areas, warmer climate (cultivate crops)
what are some of the lines of evidence that scientists used to determine that early humans
probably migrated along a coastal route as well correct answers "Arlington springs man"
crossed the Bering strait land bridge
Artifacts in Monte Verde
When did coasts first become a tourist destination? When did they become a major destination
spot? correct answers tourist destination after WWII
after 1900s
Berm & Berm crest correct answers separates beach face from back shore
beach scarp correct answers
Are barrier islands just a strip of sand or are they part of a complex of environments that all
evolve together? Be able to describe what that evolution may entails correct answers barrier
islands: Sandy strip of land out in the ocean separated from the mainland by a lagoon.
What is a delta and why are some vulnerable to sea level rise ( Mississippi River delta) **
correct answers deltas are where rivers meet the sea or lake, they are low lying so they are very
vulnerable to SLR.
how does a coastal headland evolves into a sea stack. What causes this to occur and what
landforms are the intermediate steps between a headland and a sea stack? correct answers starts
with a big rock, has so much erosion that it forces caves, stacks, etc...
why are costal foredunes important? what's their role in coastal evolution and mitigating coastal
vulnerability ** correct answers they protect the coast
first line of defense when a storm wave comes through
helps nourish the beaches
are wide beaches always totally safe from storm impacts? correct answers the wider the beach,
the less vulnerable it is
(not necessarily though, storm surges can raise water levels and impact low elevation )
how does changing water level (sea level or lake level) alter the magnitude of storm impact
where the waves are causing erosion correct answers sea level rises: the waves move landward
sea level falls: waves move seaward
, are there strong astronomical tides in the Great Lakes? Why or why not correct answers They do
not.
whats the difference between a diurnal tide and semi-diurnal tide correct answers
what is the term for the tidal range in a place like the Bay of funny where it is greater than 4m?
correct answers
Spring tide vs. neap tide correct answers
why would a perigean spring tide result in increased coastal flooding correct answers spring tide
happening when the moon is closest to earth so it is even higher.
what is the relationship between salt marsh plants, tides and sea level? How have scientists used
this relationship to uncover what past sea levels were correct answers
High tide flooding correct answers flooding which causes public inconvenience
what is a storms surge and when in the tidal cycle would the worst surge occur correct answers
Seiche vs. meteotsunami correct answers
wave height/ crest/ trough correct answers
4 factors that control type and size of wind waves correct answers - wind velocity
- wind duration
- fetch
- original sea state
identify direction of maximum fetch for given coastal location correct answers longer fetch:
bigger waves can build
shorter fetch: smaller waves can build
direction of the biggest fetch is the direction its coming from
significant wave height correct answers highest 1/3 of all waves because it has the most impact
what happens when a wave transitions from a deep water wave to a shallow water wave correct
answers In deep water: no connectivity between ground and wave no sediments moving
Shallow water: waves feel the bottom, the orbitals spin off
as approaching shallow water, spin off energy hits the bottom slowing the wave down and
stopping the water and hitting the top
Spilling vs. Plunging breakers correct answers spilling: horizontal beach
plunging: steep beach
surging: very steep beach
