It is true that parabolic dunes were commonly active in Georgia, and the Southeast at about 20,000 years ago. (The answer is True).

Parabolic dunes form when strong winds blow and erode the vegetated parts of the sand. The shape of these parabolic dunes is like a U shape with a convex nose and elongated arms. Parabolic dunes are also known as U-shaped, hairpin or blowout. This type of dunes is known in coastal desert areas. These parabolic dunes often occur in semiarid areas when precipitation persists at the bottom of the dunes as well as the soil on the underside

Answer:

It is A

Explanation:

Barrier islands are constantly shifting and evolving due to a variety of factors, including the accumulation and removal of sand. The most important factor in this process is the balance between sediment input and output.

If sediment input exceeds output, the island will grow and expand. Conversely, if sediment output exceeds input, the island will shrink and may even disappear entirely.
There are several factors that can influence the balance between sediment input and output. For example, wave action and ocean currents can transport sand onto or away from the island, while storms and hurricanes can erode and redistribute the sand. Human activities such as dredging, beach nourishment, and development can also have a significant impact on sediment input and output.
To successfully manage and preserve barrier islands, it is important to understand and monitor these factors and their effects on the island's size and shape. This can involve ongoing monitoring of sediment levels and movement, as well as careful planning and management of development and restoration projects. By balancing sediment input and output, we can help ensure the long-term health and stability of these important coastal habitats.

Ethiopia has a relatively unequal population distribution due to two factors: the first is due to Ethiopia's cold climate and rocky terrain, which restrict agricultural activity; the second is due to Ethiopia's hot climate and little rainfall.

What is the population distribution of Ethiopia?

According to estimates, Ethiopia's population density in 2019 was 112 per Km2 (290 per mi2), based on a total land area of 1,000,000 Km2 (386,102 sq. miles).

Is Ethiopian population growth a benefit or burden Why?

This is due to the dependency burden—a term used to characterize the number of people who are seen to be economically unproductive, such as children and the elderly—growing rapidly with the population.

What are major factors that affect population distribution in Ethiopia?

The climate, namely the amount of rainfall and temperature, the soil and vegetation, drainage, and slope, is the most significant physical element that determines the distribution of the population in Ethiopia. The majority of these physical characteristics are affected by altitude in Ethiopia.

One important unanswered question related to the geology of the terrestrial worlds is: What is the extent and composition of subsurface water on other planets and moons?

The presence of water is a crucial factor in determining a celestial body's potential habitability and understanding its geological history. While we have evidence of surface water on some terrestrial worlds, such as Mars and Earth's Moon, the extent and composition of subsurface water remain largely unknown. Answering this question is essential for gaining a comprehensive understanding of the potential for life beyond Earth and for uncovering the geological processes that shape these worlds.

Exploring the extent and composition of subsurface water would require a combination of remote sensing techniques, in situ measurements, and sample return missions. Remote sensing instruments like ground-penetrating radar and spectrometers can provide valuable information about subsurface water through the analysis of electromagnetic signals and absorption features. These instruments would enable scientists to map the distribution and properties of subsurface water on various terrestrial worlds.

In situ measurements, such as drilling or excavating, would be necessary to directly access subsurface water and obtain physical samples. These samples could provide insights into the composition, isotopic ratios, and potential biological activity within subsurface water reservoirs. Sample return missions, like the OSIRIS-REx mission that returned samples from asteroid Bennu, would allow for detailed laboratory analysis of subsurface water samples on Earth.

Answering the question about subsurface water would contribute to our understanding of the potential habitability of other worlds and shed light on the geological processes that shape their surfaces. It would also provide crucial information for future manned or robotic missions, aiding in the planning of resource utilization and colonization efforts.

MPI's times-interest-earned (TIE) ratio is 5.04.

The TIE ratio measures a company's ability to cover its interest expenses using its earnings before interest and taxes (EBIT). To calculate the TIE ratio, we need to determine the EBIT. Given that the basic earning power (BEP) ratio is 12%, we can calculate the EBIT as follows:

EBIT = BEP × Total Assets.

EBIT = 0.12 × $6 billion = $720 million.

Next, we use the ROA to find the operating income before taxes (EBT). EBT = ROA × Total Assets.

EBT = 0.07 × $6 billion = $420 million.

Now, we can calculate the interest expense by subtracting the EBT from the EBIT: Interest Expense = EBIT - EBT = $720 million - $420 million = $300 million.

Finally, we can compute the TIE ratio by dividing the EBIT by the interest expense: TIE = EBIT / Interest Expense = $720 million / $300 million ≈ 5.04. Rounded to two decimal places, the TIE ratio is 5.04.

Several rivers, like the River Thames, do not create deltas. These wide floodplains are also referred to as bottomlands or floodplains.

Sediments carried by swiftly moving water rapidly cut the surface straight downwards which in turn creates valleys with a V shape. An area of land next to a river that stretches from the banks of its channel to the foot of the surrounding valley walls is referred to as a floodplain or bottomlands.

These geological structures or creations are the result of moving glaciers and flowing rivers. Valleys are low-lying sections of land that have been eroded and washed out by the antagonistic forces of gravity and water.

The impact of sea level change on the Pacific Coast versus the Atlantic Coast is a complex issue that depends on a variety of factors. However, in general, the Pacific Coast is expected to experience a more significant impact than the Atlantic Coast.

One reason for this is that the Pacific Coast is more geologically active, with frequent earthquakes and volcanic activity that can exacerbate sea level rise.

In addition, the Pacific Coast has a larger area of low-lying land than the Atlantic Coast, which makes it more vulnerable to flooding and erosion.
Another factor is the presence of certain natural features, such as fjords and steep cliffs, that can magnify the effects of sea level rise.

The Pacific Coast also has a higher concentration of major cities and infrastructure than the Atlantic Coast, which means that the economic and social impacts of sea level rise could be more severe.
However, it's important to note that the impacts of sea level rise will be felt differently in different regions of both coasts, depending on factors such as local topography, climate, and human activities.

Ultimately, both coasts will need to prepare for and adapt to the inevitable effects of sea level rise, in order to protect people, property, and natural resources.

The claim that "The North Star (Polaris) will always be in this position in the night sky" is false.

The star Polaris, which appears to be stationary in the night sky, is the one that is closest to the Earth's axis. Polaris is truly moving, though, and will eventually stray from the celestial North Pole. This is due to the Earth's axis's gradual precession, or top-like swaying.

One precession cycle of the Earth's axis takes approximately 26,000 years to complete. This implies that Polaris won't always remain the North Star. Another star, Vega, will replace the North Star in roughly 12,000 years.
