Detrital sedimentary rocks are classified mainly on the basis of... 1) Colors of the cementing minerals
2) Grain sizes of the detrital particles
3) Compositions of soluble minerals
4) Degree of compaction and lithification
Detrital sedimentary rocks are classified mainly on the basis of the grain sizes of the detrital particles. Therefore, the correct answer is the second option.
Detrital sedimentary rocks are rocks that form from the weathering and erosion of pre-existing rocks. This process is known as mechanical weathering. Weathering refers to the breakdown of rock into small particles while erosion involves the transportation of weathered rock by various agents such as water, wind, and ice.
When sedimentary rocks are formed from the transported sediment that has accumulated over time and are cemented together, they are referred to as detrital sedimentary rocks. Detrital sedimentary rocks are characterized by the size and shape of the sediment that they are made up of.

Mechanical circumstances for dormancy may be broken by ______________ , an artificial method where the seed is scratched or dipped in acid to break down its coat. Dormancy can also be broken naturally through ____________ by rocks, or alternate periods of freezing and thawing.
Mechanical circumstances for dormancy may be broken by scarification, an artificial method where the seed is scratched or dipped in acid to break down its coat. Dormancy can also be broken naturally through abrasion by rocks, or alternate periods of freezing and thawing.
Scarification is the process of breaking the hard outer shell of a seed to allow water to penetrate and initiate germination. This is accomplished by mechanical abrasion (such as rubbing the seed between two surfaces) or by exposing the seed to an acid bath.
The goal of scarification is to reduce the hardness of the seed coat, making it permeable and allowing water to enter and initiate germination.
Abrasion, also known as weathering, is the process of physical breakdown of rocks and soil through forces such as wind, water, or ice. As rocks move and bump against each other, small particles are scraped off and can abrade the outer layer of a seed. This can result in enough weakening of the seed coat to allow the seed to germinate.
Alternating periods of freezing and thawing can also break the dormancy of a seed. This process, known as "cold stratification", involves placing the seed in a moist environment and then subjecting it to temperatures of 4°C (39°F) or below for a period of several weeks or months.
This simulates the conditions that occur in nature during winter, and the temperature fluctuations help to break down the seed's protective coating.
In conclusion, dormancy of seeds can be broken through scarification, abrasion, or cold stratification. By understanding the effects of these processes, gardeners and farmers can ensure that their plants and crops have the best chance of germinating and reaching maturity.

what does this ancient sedimentary rock rich in iron indicate about the conditions in which it was deposited?
This ancient sedimentary rock rich in iron indicates that the conditions in which it was deposited were likely oxygen-deprived and relatively still.
This is because iron is only able to be deposited and preserved in environments that don't contain significant amounts of oxygen, as it quickly oxidizes in the presence of oxygen.
Also, sedimentary rocks form when sediment is deposited in a relatively still environment, and iron is able to form deposits due to its high density. The environment in which the sedimentary rock was likely deposited was an anoxic (low oxygen) environment, as indicated by its high iron content.
The lack of oxygen and still environment indicates that the ancient environment where this sedimentary rock was deposited was not conducive to life.
In an anoxic environment, there is little to no oxygen to support aerobic organisms, and the still environment would have prevented circulation and the transport of nutrients, making it even less hospitable for life.
The fact that this sedimentary rock contains high levels of iron is a clear indication of the conditions in which it was deposited. This sedimentary rock was likely deposited in an oxygen-deprived and relatively still environment, making it hostile to life.

T/F: a northern hemisphere ocean basin with a standing-type tidal oscillation will have a standing wave that rotates counterclockwise.
True : A standing wave that moves in the opposite direction of the clock will exist in an ocean basin in the Northern Hemisphere with a standing-type tidal oscillation.
Do tides rotate in ocean basins?Counterclockwise rotation of the tidal crest around the basin continues. On one side of the basin, the tide is high, and on the other, it is low. The tide wave rotates clockwise (viewed from above) in basins of the Southern Hemisphere because the Coriolis deflection is reversed.
The open ocean, in addition to seas and large embayments, are well-served by this so-called dynamic model of tides. A series of cotidal lines that radiate outward from a central node, similar to the spokes on a bicycle wheel, provide ocean scientists with a visual representation of the rotatory motion of the tide wave in a basin. Points where high tide occurs at the same time of day are connected by a cotidal line; They are typically drawn once an hour. Along the coast, the tidal range ranges from zero at the node to a maximum at the antinode.

The relative fitness of the vV genotype can be calculated by comparing it to the relative fitness of the WW genotype. Since WW homozygotes produce, on average, 2.2 kids, and wv heterozygotes also produce, on average, 2.2 kids, then the relative fitness of the WW genotype is 1.0.
Since w homozygotes produce, on average, 1.7 kids, then the relative fitness of the vV genotype is (1.7/2.2) = 0.77. This means that the vV genotype has a lower relative fitness than the WW genotype.
This difference in relative fitness between the WW and vV genotypes is due to the fact that w homozygotes are more likely to have the disease, which reduces their reproductive success.
This is an example of natural selection in action, as individuals with the WW genotype have a higher relative fitness than individuals with the vV genotype, and so the WW genotype is more likely to be passed on to future generations.

The right answer is option d) freshwater coastal swamps and bogs. Coal beds are formed from the accumulation of dead plant material that has been buried and compressed over time.
This plant material accumulates in oxygen-poor environments such as swamps and bogs, where it is slowly transformed into peat, a precursor to coal. As more and more plant material is deposited and buried, the weight of overlying sediment compresses the peat, causing it to lose water and become denser. Over millions of years, this process transforms the peat into coal.
Therefore, coal beds are typically found in areas that were once covered by large, freshwater swamps and bogs, such as the Carboniferous period (about 300 million years ago) in North America and Europe.

What is the cause of the difference in surface water salinity between equatorial and subtropical regions in the atlantic ocean?
Answer:
This is because equatorial regions also get a high volume of rain on a regular basis, which dilutes the surface water along the equator. So the higher salinities are found at subtropical, warm latitudes with high evaporation and less precipitation.
Explanation:
