& Ans!!
What is the littoral zone? ✔✔the area between the sublittoral zone and the
high-water line
What are the three different types of shores? ✔✔rocky sandy muddy
Which type of shore is the most resistant to erosion? ✔✔rocky
Which type of shore is the most exposed to erosion? ✔✔rocky
What are rocky shores made out of? ✔✔granite and sandstone
Which type of shore has the most biodiversity? ✔✔rocky
Which type of shore has the least biodiversity? ✔✔sandy
What makes rocky shores so diverse? ✔✔stable substrate and tide pool
what environmental factors influence shore communities ✔✔slope, aspect,
desiccation, temperature, wave action, light intensity, and nature of substrate
name the two ways shores are formed ✔✔erosion and deposition
,what is the nature of sandy shore substrate? why? ✔✔unstable. fine particles
are easily moved by winds and tides
Why are sandy shores the least diverse ✔✔unstable substrate, lack of shelter
what do organisms on sandy shores do to make up for the unstable substrate
✔✔burrow
which shore is least exposed to erosion ✔✔muddy
what is an estuary ✔✔semi-enclosed body of water
what is a delta ✔✔river carrying suspended sediments
what are mangroves ✔✔trees and shrubs in tropical saline coastal habitats
what are the two types of mangrove structures ✔✔pneumatophores and
aerials
what are pneumatophores ✔✔specifically adapted root-like structures that
obtain oxygen directly from air
what are the benefits of extensive root systems in mangroves ✔✔they trap
particles suspended in water, they reduce water flow, and they dissipate wave
action
, what are the different types of mangroves ✔✔red, black, white
what are the two types of crust ✔✔continental and oceanic
what is continental crust made out of ✔✔granite
what is oceanic crust made out of ✔✔basalt
what is the mohorovicic discontinuity ✔✔boundary between crust and mantle
evidence for plate tectonics ✔✔mid ocean ridge, pangea, plant and animal
fossils found regions across the sea from their origin, rock strata, paleoclimatic
what are plate boundaries ✔✔where plates met
how do plates move ✔✔the unequal heating of magma
what are the different types of boundaries ✔✔divergent, convergent, transform
what are divergent boundaries ✔✔when plates move away from each other
how are ridges formed ✔✔two plates pull apart and rises magma cool off
