An estuary is best defined as a place where--
fresh and salt water meet
a river meets the Chesapeake Bay
a group of animals are gathered
the water from the land flows into a river
Which letter marks the estuary in the diagram shown?
B
C
A
These areas of dark, muddy sand exposed at low tide accumulate decaying organic matter, giving off a foul odor.
Barrier beach.
Mudflats.
Mangrove swamps.
Lagoon.
An assemblage of mangrove trees found in coastal habitats.
Mangrove pod.
Mangrove swamp.
Mangrove herd.
Mangrove patch.
A body of shallow water separated from the ocean by barrier islands or barrier beaches:
Sound.
Mudflat.
Salt marsh.
Lagoon.
What are some plants you might find in an estuary?

Fringing
Atoll
Barrier
Deep water
What is a mixture of salt and freshwater called?

photosynthesis
bioluminescence
chemosynthesis
regeneration
What is a salt marsh?
near coral reefs
deep ocean
grassland flooded with sea water
sand and salt
why mangrove needs aerial root?
to get oxygen during high tide
For respiration at night
For photosynthesis at day time
For animal habitats such as crabs
Black smoke from hydrothermal vents is due to the presence of these elements...
calcium carbonate.
iron, copper, and zinc.
barium and oxygen.
silicon and calcium.
What are some organisms found near hydrothermal vents?
dolphins and whales
lemon sharks and Christmas tree worms
serpulid worms, tubeworms, and mussels
Where are hydrothermal vents are found mostly around...
mid-ocean ridges and seamounts.
continental shelf.
guyots and abyssal plain.
middle of the ocean.
Chemosynthetic bacteria can form a symbiotic relationship with
hydrothermal vent
algae
giant tube worms and giant clams
the vent fluid
What gives the hydrothermal fluid the appearance of smoke
The fluid carries dissolved bacteria from deep beneath the ocean floor. When the fluid mixes with sea water, these bacteria combine with sulfur to form tiny black particles. These particles make the fluid look like smoke.
The fluid carries dissolved metals from deep beneath the ocean floor. When the fluid mixes with sea water, these metals combine with sulfur to form tiny black particles. These particles make the fluid look like smoke.
The fluid carries dissolved from animal debris deep beneath the ocean floor. When the fluid mixes with sea water, the debris combine with sulfur to form tiny black particles. These particles make the fluid look like smoke.
Which has a hotter temperature, the white smoker or the black smoker ?
white smoker
black smoker
neither
