what does the existence of machu picchu suggest about the power of the inca king?
The existence of Machu Picchu suggests that the Inca king or emperor, Pachacuti Inca Yupanqui, had significant power and resources at his disposal. Machu Picchu is an ancient Inca citadel located in the Andes Mountains of Peru
It is thought to have been constructed in the middle of the 15th century as a royal estate for Pachacuti Inca Yupanqui. It is reasonable to assume that the Inca king had the strength and authority to command the necessary materials and labor force given the amount of labor, resources, and organization required to build such a monumental and elaborate structure in a remote and inaccessible location. Additionally, Machu Picchu's strategic location, with a view of the Urubamba River Valley, may have represented Inca power and control over the neighboring lands symbolically.
However, it's important to note that there are still many unanswered questions about the function and significance of Machu Picchu, and historians continue to disagree about its exact place in Inca politics and society.

Salt marsh __________ help prevent erosion and stabilize shorelines.
Salt marsh vegetation can help prevent erosion and stabilize shorelines.
Salt marshes are coastal wetlands that are regularly flooded and drained by salt water brought in by the tides. Salt marshes are found in temperate and high-latitude areas throughout the world's coastlines, from tropical regions to polar regions.
Salt marshes play a significant role in protecting coastlines from erosion by buffering the force of waves and tides, absorbing storm surges, and holding sediment in place with the roots of vegetation. In addition, they protect low-lying regions from the dangers of coastal flooding by absorbing storm surges and dissipating wave energy. As a result, salt marshes serve as a crucial buffer between the ocean and land, safeguarding the coast and its inhabitants from the hazards of coastal erosion and flooding.

what is foliation? group of answer choices parallel bedding in a rock formed by successive depositional events parallel orientation of platy minerals caused by complete melting parallel orientation of platy minerals caused by metamorphism parallel cracking or jointing of a rock due to stress
Foliation, a result of metamorphism, is the parallel orientation of platy minerals in a rock.
The parallel orientation of flat or platy minerals within a rock is referred to as foliation. The minerals align themselves perpendicular to the direction of the highest stress because to the severe pressure and/or heat that occurs during metamorphism. As a result, the rock develops a characteristic layering or banding pattern. Foliation is distinct from parallel bedding, which is created by several depositional occurrences, and from cracking or jointing, which is brought on by stress but excludes mineral alignment. Metamorphic rocks, such as schist and gneiss, frequently exhibit foliation, which can provide important details about the rock's geological past.

Answer:
When water moves around a bend in the river it moves very fast on the outer edge, picking up sediments.
When water moves around a bend in the river it moves very fast on the outside edge, picking up sediments.
A meander bend, also known as a horse-bends, is a large bend in a river. Meandering rivers are divided into two categories: constant and sinuous. Meanders in constant meandering rivers are tighter and smoother than those in sinuous meandering rivers.
When water moves around a bend in the river it moves very fast on the outer edge, picking up sediments. The river's sediment transport is a crucial aspect of river dynamics. The amount of sediment transported by rivers is influenced by a variety of factors. The energy and speed of the water is the most essential aspect. The amount of sediment the water is carrying is also important. Suspended sediment is frequently transported in the river flow. Sediment is swept downstream and can accumulate where the water slows down or is obstructed in areas where the flow is disrupted. Such regions are often good areas for deposition.

generally speaking, which seismic waves will have the greatest amplitude [height from top to bottom] on a seismogram?
P waves generally have the greatest amplitude on a seismogram. P waves are the fastest seismic waves, meaning they arrive at the detector first and have the highest amplitude when they reach the seismometer.
P waves are also the most energetic of the seismic waves. This is because they are generated by a sudden release of energy at the focus of an earthquake, and since they travel fastest, they retain more energy as they move through the earth.
This energy is then released at the surface and measured by the seismometer.

what type of estuary occurs within the mouth of a river flowing directly into salt water? here fresh water flows out to sea at the surface, and denser seawater flows upstream along the river bottom.
A type of estuary that occurs within the mouth of a river flowing directly into saltwater is a salt wedge estuary. This type of estuary is characterized by freshwater that flows out to the sea at the surface, while denser seawater flows upstream along the river bottom.
A salt wedge estuary is a type of estuary that is primarily influenced by a river's flow, as well as the tidal forces of the ocean. In this type of estuary, seawater, which is denser than freshwater, will enter the river's mouth and flow upstream along the river bottom, creating a wedge-like shape.
The freshwater, which is less dense, will flow over the denser seawater and form a layer on top. The result of this phenomenon is a stratified water column in the river, with saltwater at the bottom and freshwater at the top. This creates a unique habitat for marine and freshwater species alike.
Salt wedge estuaries are commonly found in areas with low tidal ranges, such as the Mississippi River in the United States or the Murray River in Australia.

based upon what occurred during the magnitude 9.0 earthquake on the cascadia subduction zone in 1700, how might an earthquake there affect the california coastline?
The magnitude 9.0 earthquake that occurred in the Cascadia Subduction Zone in 1700 could have a devastating impact on the California coastline. . It caused a massive tsunami to form, which traveled all the way to Japan and destroyed many coastal towns along the way. Additionally, the earthquake caused a powerful lateral spreading of the ground, which caused landslides in some areas and tsunamis in others. These tsunamis could potentially cause destruction along the California coastline if the same type of earthquake were to occur in the future.
It is important to note that the California coastline is composed of three different fault lines: the San Andreas, the Mendocino, and the Cascadia Subduction Zone. If an earthquake were to occur on the Cascadia Subduction Zone, it would most likely cause the most destruction. This is because of the close proximity of the two fault lines and the potential for powerful waves to be produced.
Furthermore, an earthquake on the Cascadia Subduction Zone would have the potential to trigger other earthquakes along the other two fault lines. These earthquakes could potentially cause large amounts of destruction due to their power and the fact that they could spread over a larger area.

at nearly all the stations, the season receives the greater amount of precipitation on average. a. summer b. winter
The answer is "b. winter". In most stations, the winter season receives a greater amount of precipitation on average compared to summer.
At almost all locations, the winter season typically experiences higher precipitation totals. This is because the air becomes colder and less able to hold moisture during the winter when the temperature decreases. As a result, clouds form from the condensation of the air's moisture, bringing forth precipitation. Winter storms also bring a lot of precipitation, including snow, sleet, and freezing rain, to many areas. Although thunderstorms can occasionally occur in the summer, they are typically more confined and localised than storms that occur in the winter. Therefore, across most locations, winter is the time of year that sees the highest precipitation.

which boundary has the deepest earthquakes? why do you think the earthquakes are deepest here? what do you notice about the depth of the earthquake, the farther you go away from this boundary? why do you think this is so?
This is due to the fact that convergent boundaries have more intense pressure, resulting in greater earthquake depths.
The boundary with the deepest earthquakes is the convergent plate boundary, which is when two tectonic plates move toward each other and one plate slides beneath the other. This movement creates a deep-focus earthquake which can reach depths of up to 700km below the surface of the Earth.
The reason why earthquakes are deepest at convergent plate boundaries is because the intense pressure between the plates creates more friction and causes more intense earthquakes. Additionally, the downward motion of one plate beneath another can create deeper earthquakes due to the increased pressure at greater depths.
When looking at earthquakes at different types of boundaries, it is noticed that the farther away from a convergent boundary, the shallower the earthquakes tend to be. This is due to the fact that convergent boundaries have more intense pressure, resulting in greater earthquake depths.
