What kind of sediment settle in the sound?
-
Fine silt
-
Loam
-
Coarse sand
-
Clay
Correct Answer
A. Fine siltExplanation
Fine silt is the type of sediment that settles in the sound. Silt particles are smaller than sand particles but larger than clay particles. They have a smooth texture and can be easily transported by water. When the water in the sound slows down, it is unable to carry the silt particles anymore, causing them to settle at the bottom. This fine silt sediment is commonly found in areas with calm waters, such as in estuaries or bays.Rate this question:

What kind of sediments settle on the ocean beach?
-
Silt
-
Gravel
-
Coarse sand
-
Clay
Correct Answer
A. Coarse sandExplanation
Coarse sand is the correct answer because sediments that settle on the ocean beach are typically larger in size due to the wave action and strong currents. Coarse sand particles are larger than silt and clay particles, and they are commonly found on beaches where the waves have enough energy to transport and deposit them. Gravel is also a possibility, but it is less common on ocean beaches compared to coarse sand.Rate this question:

-
The supratidal zone of crashing breakers with swirling sand and shallow water; the intertidal zone, alternately covered and exposed by tidal waters; and the dry, sandy subtidal zone extending to the base of the sand dunes.
Correct Answer
A. The subtidal zone of crashing breakers with swirling sand and shallow water; the intertidal zone, alternately covered and exposed by tidal waters; and the dry, sandy supratidal zone extending to the base of the sand dunes.Explanation
The correct answer is the subtidal zone of crashing breakers with swirling sand and shallow water; the intertidal zone, alternately covered and exposed by tidal waters; and the dry, sandy supratidal zone extending to the base of the sand dunes. This answer accurately describes the three distinct zones found in ocean beach habitats. The subtidal zone refers to the area below the low tide mark, where crashing waves and swirling sand are present. The intertidal zone is the area that is covered and exposed by tidal waters, experiencing regular changes in water level. The supratidal zone is the area above the high tide mark, where the sand dunes are located.Rate this question:

Oxygen is plentiful in the ocean beach habitat because of which three factors:
-
Wind coming off the ocean, the presence of water coming in with the tides and in the space between the sand sediment.
-
The presence of water coming in with the tides, salt spray and plants.
-
The wind coming off the ocean, salt spray and plants.
-
The wind coming off the ocean, the presence of water coming in with the tides and plants.
Correct Answer
A. Wind coming off the ocean, the presence of water coming in with the tides and in the space between the sand sediment.Explanation
The correct answer is that oxygen is plentiful in the ocean beach habitat due to the wind coming off the ocean, the presence of water coming in with the tides, and in the space between the sand sediment. The wind helps to circulate the air and bring in fresh oxygen from the ocean. The water coming in with the tides also carries oxygen from the ocean. Additionally, the space between the sand sediment provides a habitat for oxygen-producing organisms like algae and bacteria, further increasing the oxygen levels in the beach habitat.Rate this question:

Debris and detritus are deposited ___________________
-
At the high tide line.
-
At the shoreline.
-
Along the shoreface.
-
In the intertidal zone.
Correct Answer
A. At the high tide line.Explanation
Debris and detritus are deposited at the high tide line because this is the area where the highest level of water reaches during high tide. As the tide recedes, it leaves behind the debris and detritus that was carried by the water. This line marks the boundary between the wet and dry areas of the shore, making it a logical location for the deposition of debris and detritus.Rate this question:

-
Free floating microscopic plants that are the basis of the marine food chain.
-
Free floating microscopic animals that are the basis of the marine food chain.
-
Free floating microscopic scavengers that support the marine food chain.
-
Diatoms that cause red tide and are toxic to the marine food chain.
Correct Answer
A. Free floating microscopic plants that are the basis of the marine food chain.Explanation
Phytoplankton are free floating microscopic plants that are the basis of the marine food chain. They play a crucial role in the ecosystem by converting sunlight and nutrients into organic matter through photosynthesis. This organic matter then becomes food for other organisms in the marine food chain, such as zooplankton, small fish, and ultimately larger predators. Phytoplankton are responsible for producing a significant amount of the Earth's oxygen and are essential for maintaining the health and balance of marine ecosystems. They are not animals, scavengers, or toxic diatoms causing red tide.Rate this question:

-
A gastropod is a mollusk that has two shells it is a bivalve or pelecypod with a strong muscular foot.
-
A gastropod is a mollusk that attaches itself to hard substrate to survive.
-
A gastropod is a mollusk that has an internal shell like a squid.
Correct Answer
A. A gastropod is a mollusk that has one shell. It is a marine snail.Explanation
A gastropod is a type of mollusk that has one shell. Specifically, it is a marine snail. This means that it is a snail that lives in the ocean and has a single shell for protection. Other mollusks, such as bivalves or pelecypods, have two shells, so they are not considered gastropods. Additionally, gastropods do not attach themselves to hard substrate to survive, nor do they have an internal shell like a squid.Rate this question:

Coarse sand settles in the intertidal zone because:
-
Turbulent ocean waves can carry coarse sediment and deposit it on the shoreline.
-
Turbulent ocean tides can carry coarse sediment and deposit it on the shoreline.
-
Gentle sound waves deposit coarse sediment in the ebb tidal deltas.
-
The longshore current carries coarse sediment to the shore.
Correct Answer
A. Turbulent ocean waves can carry coarse sediment and deposit it on the shoreline.Explanation
Turbulent ocean waves have the energy and force to carry coarse sediment and deposit it on the shoreline. The strong waves can pick up and transport larger particles, such as coarse sand, and then deposit them when the waves break or recede. This process is common in the intertidal zone, where the waves impact the shoreline. The other options, such as ocean tides, sound waves, or longshore currents, may also have some influence on sediment transport, but they are not as directly related to the settling of coarse sand in the intertidal zone as turbulent ocean waves.Rate this question:

Tides- the daily cycle of 2 high and 2 low tidal flow of water onto and into a low lying shore area caused by the:
-
Moon and sun’s gravitational pull on Earth.
-
Moon's gravitational pull on Earth.
-
Sun’s gravitational pull on Earth.
-
The oceans wave energy.
Correct Answer
A. Moon and sun’s gravitational pull on Earth.Explanation
The tides are caused by the gravitational pull of both the moon and the sun on Earth. The moon's gravitational force is stronger because it is closer to Earth, but the sun also has a significant influence. As the moon and sun exert their gravitational pull, they create a bulge of water on the side of the Earth facing them, causing a high tide. On the opposite side of the Earth, there is also a high tide due to the centrifugal force of the Earth's rotation. As the Earth rotates, different areas experience high and low tides throughout the day.Rate this question:

The action of ____________________ sweeps larger shell particles and sand across the substrate surface, sometimes causing abrasions or burying plants and animals.
-
Waves
-
Tides
-
Longshore current
-
Winds
Correct Answer
A. WavesExplanation
Waves have the ability to generate a force that can move larger shell particles and sand across the substrate surface. This movement can sometimes cause abrasions or bury plants and animals. Waves are formed by the transfer of energy from the wind to the water surface, resulting in the oscillation of water particles. As waves approach the shore, they become higher and break, exerting a strong force on the substrate and causing movement of sediment.Rate this question:

Correct Answer
A. Most supratidal animals are__scavengers_________ that feed__on debris along the____ strand line____Explanation
Most supratidal animals are scavengers that feed on debris along the strand line. The term "supratidal" refers to the area above the high tide line, where these animals are commonly found. Scavengers are organisms that feed on dead and decaying organic matter, such as dead plants and animals, which are often washed up along the strand line. This food source is abundant in the supratidal zone due to the constant movement of the tides. Therefore, supratidal animals have adapted to be scavengers in order to take advantage of this food resource.Rate this question:
