Ocean
Coast
Rocky
Sandy
3
Chemical weathering is what?
Rocks get smaller because heating/cooling/waves
breaking down rocks into smaller pieces
exposure to acid rain,rain dissolves/oxygen rusts
done by living organisms
4
What are the characteristics of the abyssopelagic zone?
200-1000m deep, receives very little light
4000-600m deep,cold temps & pressure
0-200m deep, receives enough light for photosynthesis
1000-4000m deep, receives no sunlight
5
What is the difference between weathering and erosion?
W:deposition of part. from H2O E:material is worn away from surface/trans..
E:material is worn away from surface &transported W:breaking down of rocks
E:breaking down of rocks W:material is worn away from surface &transported
E:diff.in comcentration of molecules W:outermost layer of rock on Earth

Lower,Middle,Upper,Splash zone
Splash zone, lower, upper
Middle,upper, splash zone,benthic
10
How are sandy shores formed?
Shells broken down, into sand
Soft rocks weathered into smaller pieces
wind blows rock onto shore
Runoff brings rock onto shore
11
What is sedimentation?
The deposition of suspended particles from water
breaking down of rocks
a solid that dissolves in a solvent
material worn away and transported
12
What is an estuary?
where fresh water from river meets salt water from ocean
Variation between habitats on a global level
The zone which recieves enough light for photosynthesis
Small isolated reef within a lagoon
13

Important
Threats
15
What is a benefit of mangroves to human & ecological communities?(select multiple)
Prevents tourists from damaging land

20
What is the reason for zonation on a rocky shore?
To combine organisms into one space
To reduce competition for space/food
To separate organisms based off of species
To increase competition for space/food
