As compared to subaerial basaltic lavas, submarine basaltic lavas differ in that they form pillow-like mounds because they cannot flow as far from their source. So, option c. is correct.
Subaerial basaltic lavas, which flow on the Earth's surface exposed to air, can flow for longer distances due to lower cooling rates and solidification. In contrast, submarine basaltic lavas, which are erupted under water, experience rapid cooling and solidification upon contact with water. This rapid cooling process causes the submarine basaltic lava to form pillow-like mounds, also known as pillow basalts. These mounds are characterized by their round or elongated shapes, formed as the outer layer of the lava solidifies and the still-liquid lava within breaks through, creating a new pillow. It is important to note that submarine basaltic lavas do not always produce violent pyroclastic debris flows, nor do they necessarily produce large crystals of pyroxene and plagioclase.
The formation of large crystals depends on various factors, such as cooling rate and chemical composition of the lava. In general, the key difference between submarine and subaerial basaltic lavas lies in their cooling processes and the resulting morphologies, with submarine lavas forming pillow-like mounds due to their limited flow distance from the source. So, option c. is correct.

The correct answer is c. Submarine basaltic lavas form pillow-like mounds because they cannot flow as far from their source as subaerial basaltic lavas. This is due to the higher pressure and cooler temperatures of the ocean environment, which causes the lava to solidify more quickly and form distinctive pillow shapes.
Additionally, submarine basaltic lavas tend to have smaller crystals of pyroxene and plagioclase due to the rapid cooling process, while subaerial lavas may have larger crystals due to slower cooling on the surface. There is generally less explosive activity associated with submarine basaltic lavas compared to subaerial lavas, so they do not typically produce violent pyroclastic debris flows. Submarine basaltic lavas differ from subaerial basaltic lavas in that they cool much more rapidly due to the surrounding cold water, which can cause them to form distinctive pillow-shaped mounds of rock. In contrast, subaerial basaltic lavas have a chance to flow longer distances before cooling, resulting in more extensive lava flows with characteristic flat, smooth surfaces. Submarine basaltic lavas can also have different chemical compositions than subaerial basaltic lavas, due to differences in the conditions under which they form.

explain to a conoeist (someone who rows a small boat )it is not recommended to follow the inner banks of the river in this course of the river
Answer:
Dear canoeist,
I would like to advise you that it is not recommended to follow the inner banks of the river in this course of the river. This is because there might be obstacles or currents that can make rowing difficult and even put you in danger. The outer banks are usually less steep and have less undercurrent, making it easier to navigate the river safely. Additionally, following the inner banks might also disturb the natural ecosystem of the river, which can have negative consequences. It is essential to keep yourself and the river safe by following the recommended path, which usually means not sticking to the inner banks.
Best regards,
Drake
I hope this answers your questions
There are a few reasons why it is not recommended for canoeists to follow the inner banks of a river in certain courses.
The current is stronger: The inner banks of a river are often where the current is strongest. This is because the water is constricted by the banks, so it has to flow faster to get through. This can make it difficult for canoeists to control their boats, and it can also increase the risk of capsizing.
There are more hazards: The inner banks of a river are often where there are more hazards, such as rocks, debris, and underwater stumps. These hazards can damage a canoeist's boat, and they can also pose a safety risk.
The view is obstructed: The inner banks of a river often obstruct the view of the river ahead. This can make it difficult for canoeists to see what is coming, and it can increase the risk of collisions.
So, it is generally recommended for canoeists to follow the outer banks of a river whenever possible. The outer banks are often where the current is weaker, there are fewer hazards, and the view is better.

If you decide to sponsor an adoption, you are facilitating the transition of an animal into a new home. Only a reduced adoption cost will be due from the adoptive parent.
These fees assist in paying for the care of other animals in the shelter or rescue organization who might have medical expenses that are significantly more expensive than any prospective adoption fee. The charge serves as a donation to the organization as a whole, enabling it to keep up its efforts to rescue and rehome animals. Contrary to the conventional image of cats as being primped and spoiled, cats don't need nearly as much upkeep or resources as dogs do, hence dogs are more expensive to adopt, buy, and care for.

Calculate how much water is expelled from a shale layer 1 km thick and 10 • 10 km in area, as it is buried from 1 km to 3 km depth, assuming its compaction is in equilibrium. Assume now that this is a source rock with 600 ppm weight percent mature hydrocarbon, of which 15% get expulsed in primary migration. How much oil is generated? What is the average concentration of oil, in ppm, in the water that escapes from the shale?
During the burial process, the shale layer expels approximately 10 km³ of water, and the average concentration of oil in this water is estimated to be 9 ppm.
Expelling water from a shale layer buried from 1 km to 3 km depth involves calculating the volume of water expelled. Assuming compaction equilibrium, the amount of oil generated can be determined based on the shale's hydrocarbon content and the percentage of oil expelled in primary migration.
The average concentration of oil in the water can be derived by dividing the amount of oil generated by the volume of expelled water.To calculate the volume of water expelled from the shale layer, we multiply its thickness (1 km) by its area (10 • 10 km), resulting in 10 km³. Assuming compaction equilibrium, this volume remains constant during burial.Next, we calculate the amount of oil generated. Considering the shale's hydrocarbon content of 600 ppm (weight percent) and assuming that 15% of the mature hydrocarbons are expelled in primary migration, we multiply 600 ppm by 0.15 to obtain 90 ppm.To determine the average concentration of oil in the expelled water, we divide the amount of oil generated (90 ppm) by the volume of expelled water (10 km³).This gives us an average concentration of 9 ppm (parts per million) of oil in the water escaping from the shale layer.Therefore, during the burial process, the shale layer expels approximately 10 km³ of water, and the average concentration of oil in this water is estimated to be 9 ppm.

Group of answer choices
It must have been on the land.
It must have been exposed to the air.
It must have had flowing currents of water and these currents switched direction periodically.
It must have been deposited in a swampy environment with stagnant water.
It must have been in a shallow water environment where waves could reach the bottom.
It must have been in the deep ocean, deposited by turbidity currents.
The correct answer is It must have had flowing currents of water and these currents switched direction periodically. This must be conditions under which this sediment was deposited.
In contrast to metamorphic and igneous rocks, which are generated deep beneath the Earth, sedimentary rocks are formed on or around the surface of the planet. Erosion, weathering, dissolution, precipitation, and lithification are the main geological processes that result in the formation of sedimentary rocks. Boulders and even mountains become sediments, such as sand or mud, as a result of erosion and weathering. Chemical weathering, or dissolution, is one type of weathering.

3. Louisiana black bears live on territories at a rate up to 1. 7 bears per square mile. What would
happen if their density increased?
Answer: If the Louisiana black bear population density increased, the bears would begin to compete for resources such as food, water, and shelter. This could cause an increase in aggressive interactions between bears, increased mortality rates, and decreased reproduction rates. Additionally, increased bear densities could also lead to more frequent and serious human-bear conflicts.
Explanation:
Bear populations in the state are believed to be between 750 and 1000, although they are increasing as more natural habitat is being restored. For such populations, "we are witnessing range extension," claimed Davidson.
Black bears in Louisiana would start to compete with one another for resources like food, water, and shelter if their population density rose. This could result in more aggressive bear encounters, higher fatality rates, and lower reproduction rates. Increased bear populations may potentially result in more frequent and dangerous human-bear interactions.
According to earlier research, bear population densities typically vary between 0.5 and 1.0 bears per square mile (CDFW 1993). The Central Coast, the Transverse Mountain Range, the San Gabriel and San Bernardine Mountains are all included in the Western/Southern sub population.
