what processes associated with mountain and basin formation may accompany ocean-continent convergence?
Mountain and basin formation can occur as a result of ocean-continent convergence, which is the collision of an oceanic plate with a continental plate.
One of the main processes associated with mountain and basin formation during ocean-continent convergence is the creation of a subduction zone. As the oceanic plate moves beneath the continental plate, it can create a trench in the ocean floor. This trench can act as a focus for seismic activity and can lead to the creation of volcanoes on the continental plate.
Another process associated with mountain and basin formation during ocean-continent convergence is the formation of fold and thrust belts.

Not mentioned in the CRB article, but featured on the side, what fish-eating bird species has made a comeback since the ban on DDT?
The fish-eating bird species that has made a comeback since the ban on DDT is the bald eagle.
From the 1940s to the 1970s, the chemical compound DDT was frequently used as a pesticide in the US. It caused the eggshells of bald eagles and other bird species to become thin and brittle, which prevented them from having offspring.
The bald eagle population, which had been steadily dropping for decades, had a considerable resurgence after DDT was outlawed in the early 1970s.
As of today, there are about 10,000 nesting pairs of bald eagles in the United States, up from a low of less than 500 nesting pairs in the lower 48 states in the 1960s. This recovery is regarded as a significant achievement for the protection of endangered species.

stalagmites group of answer choices are a type of flowstone. are composed of limestone precipitated out of cave water. begin as delicate, hollow structures called soda straws. are icicle-shaped cones that hang from cave ceilings.
Stalagmites are a type of flowstone found in caves that are formed from the deposition of limestone precipitated out of cave water.
They grow from the floor of a cave upwards and are typically conical or rounded in shape. While they are often thought of as being icicle-shaped cones that hang from cave ceilings, this is actually the formation known as stalactites.
Stalagmites begin as delicate, hollow structures called soda straws, which are formed when water drips through a small opening in the ceiling of a cave. Over time, the water evaporates and leaves behind a small deposit of calcium carbonate. As more and more water drips through the opening, the deposit grows longer and thicker until it eventually forms a stalagmite.
Stalagmites can take on a variety of shapes and sizes depending on the conditions in the cave where they are formed. Some are tall and skinny, while others are short and wide. They can also be very colorful, with shades of white, beige, and brown being the most common.
Overall, stalagmites are a fascinating natural wonder that can provide insight into the geological history of an area. They are also an important part of the ecosystem in caves, providing shelter and food for a variety of cave-dwelling creatures.

continuing to watch what would be our current east coast/georgia area, during which period do the appalachian mountains reach their highest elevation (based on what you can see in the video)?
Based on what I can see in the video, the Appalachian Mountains reach their highest elevation during the period between 250 and 300 million years ago. This is known as the Alleghenian orogeny, a period of mountain building that resulted from the collision of the North American and African tectonic plates.
During this period, the eastern coast of North America was located near the equator and was covered by a shallow sea. As the North American plate moved westward, it collided with the African plate, causing the crust to buckle and fold, forming the Appalachian Mountains. The video shows a time-lapse of the eastern coast of the United States over millions of years, with the Appalachian Mountains slowly rising and falling as the tectonic plates continue to shift. While the exact timing of the highest elevation of the Appalachians may not be clear from the video alone, it is clear that the mountains have undergone significant changes over time.
Today, the Appalachians are not as tall as they were during their peak, as millions of years of erosion have worn them down. However, they still provide important ecological and geological features to the region, and are an important part of the history and culture of the eastern United States.

A continental volcanic arc is formed when an oceanic plate subducts under a continental plate, while a volcanic island arc is formed when an oceanic plate subducts under another oceanic plate.
It's important to note that both types of arcs are formed at subduction zones, where one tectonic plate is forced beneath another. However, the type of arc that forms depends on the type of plates involved in the subduction process.
In a continental volcanic arc, the subducting plate is an oceanic plate, which is denser than the continental plate it is diving beneath. As the oceanic plate descends into the mantle, it begins to melt, forming magma that rises to the surface and creates a chain of volcanoes on the continental plate above. Examples of continental volcanic arcs include the Andes Mountains in South America and the Cascade Range in the western United States.
In contrast, a volcanic island arc is formed when two oceanic plates collide and one is subducted beneath the other. As the subducting plate descends, it generates magma that rises to the surface and forms a chain of volcanic islands. The Aleutian Islands in Alaska and the Japanese archipelago are examples of volcanic island arcs.
In summary, the key difference between a continental volcanic arc and a volcanic island arc is the type of plates involved in the subduction process. A continental volcanic arc is formed when an oceanic plate subducts under a continental plate, while a volcanic island arc is formed when an oceanic plate subducts under another oceanic plate.

the principal cause of desertification is: group of answer choices inappropriate land use such as agricultural clearing and overgrazing. extended droughts in untouched rain forest climates. air pollution as rural areas become urbanized. warming global temperatures due to the burning of fossil fuels.
The principal cause of desertification is inappropriate land use, such as agricultural clearing and overgrazing. Desertification is the process by which fertile land becomes desert due to a combination of natural and human factors. Inappropriate land use can lead to soil erosion, loss of soil fertility, and the destruction of vegetation cover. This, in turn, can lead to a reduction in the amount of moisture in the soil, which can create a cycle of further degradation and desertification.
Inappropriate land use is often a result of human activities, such as agricultural practices that require extensive land clearing and overgrazing of livestock. When natural vegetation is removed, soil erosion can occur, and the soil becomes less fertile, leading to desertification. Overgrazing can also lead to the destruction of vegetation, which in turn can cause soil erosion Air pollution as rural areas become urbanized can also have an impact on desertification, but again, it is not the principal cause. Urbanization can lead to increased air pollution and the destruction of vegetation cover, but these are secondary effects that result from inappropriate land use.
In summary, the principal cause of desertification is inappropriate land use, such as agricultural clearing and overgrazing. While other factors can contribute to desertification, they are not the primary cause. To combat desertification, it is essential to adopt sustainable land use practices that preserve the natural vegetation cover and prevent soil erosion.

in which rock or sediment type is would you expect the water flow to be the least? question 1 options: silt unweathered limestone unconsolidated sand sandstone
The rock or sediment type in which you would expect the water flow to be the least is unconsolidated sand.
Unconsolidated sand refers to loose sand grains that have not been compacted or cemented together. Due to its loose nature, water can easily flow through the spaces between the grains. However, since there is no cohesion between the grains, the water flow is not hindered or slowed down by any structural integrity of the sediment. In comparison, silt particles are smaller than sand grains and are more tightly packed, which means that water flow can be slowed down or blocked by their cohesive nature. Sandstone, on the other hand, is a type of sedimentary rock formed from sand grains that have been compacted and cemented together. While water can still flow through the pores of the rock, the flow may be impeded by the rock's structure. Unweathered limestone, like sandstone, is also a compacted sedimentary rock and may hinder water flow due to its dense structure. Therefore, unconsolidated sand is the rock or sediment type in which water flow is expected to be the least obstructed.

By implementing these measures, farmers are working to protect the river basin and ensure a sustainable future for agriculture in the region.
According to the CRB article, farmers have taken two measures to protect the river basin. Firstly, they have implemented conservation practices that aim to reduce soil erosion and improve water quality. These practices include the use of cover crops, no-till farming, and precision agriculture. Cover crops protect the soil from erosion, reduce nutrient runoff, and enhance soil health. No-till farming helps to retain soil moisture, reduce erosion, and increase organic matter in the soil. Precision agriculture involves using technology to apply fertilizers and pesticides only where they are needed, reducing waste and environmental impact. Secondly, farmers have adopted water management strategies that aim to reduce water use and improve efficiency. These strategies include the use of drip irrigation, water monitoring systems, and water storage facilities. Drip irrigation delivers water directly to the root zone of plants, reducing evaporation and improving water efficiency. Water monitoring systems help farmers to track water usage and identify areas where improvements can be made. Water storage facilities, such as ponds or tanks, allow farmers to capture and store rainwater, reducing the need to pump water from the river.
