I think the correct answer to this is ‘reduced prey quality’.
This is because in the study made by Trites and Donnelly, they found out that steller sea lions were experiencing nutritional stress. Nutritional stress means that although the prey contains all the necessary nutrients, the quantity of prey is not enough due to a reduction in overall biomass of prey locally.

Oceanic crust slides under continental crust during subduction because oceanic crust is _______.
Answer:
Oceanic crust slides under continental crust during subduction because oceanic crust is denser.
Explanation:
In a convergence boundary where continental crust collides with an oceanic crust , the oceanic crust get subducted due to it more dense nature. The oceanic crust is denser because of the kind of rocks found in it. The oceanic crust is dominated by mafic rocks(basalt, Gabbro and Diabase) majorly, Basalt. Generally, this kind of rocks are heavier than the rocks found in the continental crust(usually granitic) . This kind of rocks (mafic)contribute to it(oceanic crust) dense nature.
Due to the dense nature of oceanic crust, when they collides with the more active continental crust they tend to subduct. The subduction zone causes an introduction of magma as aesthenosphere material are released through this zone . This zone is marked with volcanoes . The oceanic crust subduct to form trenches.
The picture above illustrate the colliding effects of a continental and oceanic crust.

Answer:
A. they formed an alliance with the enemies of the Aztecs
Explanation:
The conquest of the Aztecs took place between 1519 and 1521 and was one of the episodes of the Spanish invasion and colonization of America. The great Aztec Empire had been built by Mesoamerican peoples from the fourteenth century. With their conquest, the Spanish began the colonization of the region that today corresponds to Mexico.
After a great defeat against the Aztecs in 1520, Cortes did not fully reorganize his forces until 1521, when he formed a gigantic army of thousands of Tlaxcaltec warriors (enemies of the Aztecs). In addition, he built numerous vessels to surround Tenochtitlán (the Aztec capital was on an island in the middle of a large lake that no longer exists). Reports told of violent fighting taking place in the streets of Tenochtitlán.
The result of the siege of Tenochtitlán was the Spanish victory. The new emperor, whose name was Cuahtemoc, was taken prisoner, and from there the Spaniards moved on to conquer the other smaller cities controlled by the Aztecs. With the conquest of this people, the Spanish established in the region the Vice Kingdom of New Spain, which was initially administered by Cortes himself.
A passive continental margin has a _____, while an active margin does not.
Answer:
continental rise
Explanation:
Two main types of continental margins have been identified: liabilities and assets. Passive margins are found along most of the coastal areas surrounding the Atlantic and Indian Ocean, including the eastern coasts of North and South America, as well as the coastal areas of Europe and Africa. Passive margins are not located along an active plate edge and, therefore, experience very little volcanism and few earthquakes. These are places where materials from weathering and erosion of adjacent land masses accumulate, which they form a thick and wide wedge of relatively unaltered sediments.
On the contrary, active continental margins appear where the oceanic lithosphere is being subducted below the edge of a continent. The result is a relatively narrow margin, consisting of very deformed sediments that were torn from the descending lithospheric plate. Active continental margins are common around the edge of the Pacific, where they are parallel to underwater pits.

How does the increase in carbon dioxide emissions affect the earth's natural cycle of temperature change?
Final answer:
Increased carbon dioxide emissions enhance the greenhouse effect, leading to an altitude rise in the atmosphere's radiation emission and resulting in global warming. The Earth's surface warms more to balance the incoming and outgoing radiation, and added water vapor further amplifies the warming. Mitigation requires a shift to renewable energy sources.
Explanation:
The increase in carbon dioxide emissions considerably affects the Earth's natural temperature cycle by enhancing the greenhouse effect. An increased concentration of CO₂ in the atmosphere leads to a higher altitude from which the atmosphere emits radiation to space, due to increased absorption by CO₂. This results in the Earth's surface needing to warm more to maintain the balance between incoming solar radiation and outgoing emission, contributing to global warming.
Furthermore, the rise in surface temperature causes an increase in water vapor pressure, which amplifies warming as water vapor is also a potent greenhouse gas. The net effect is an acceleration of the natural carbon cycle and a change in global temperatures, leading to various consequences like altered weather patterns, decreased agricultural outputs, increasing economic instability, and environmental stress on organisms.
It is critical to note that the relationship between atmospheric CO₂ levels and global temperatures is not linear but logarithmic; thus, the precise effect on temperatures poses certain uncertainties. Nevertheless, the documented increase in average surface temperature by about 0.8°C since the pre-industrial era, with significant acceleration since the 1980s, underscores the reality of the enhanced greenhouse effect.
To mitigate these severe implications, a shift from fossil fuels to renewable energy sources like hydro, solar, wind, and nuclear is essential. This shift would help limit further increases in CO₂ levels, slowdown ocean acidification, and provide a more stable climate.

Which layer of earth possesses the greatest thickness?
The mantle is the thickest layer of Earth, extending from the base of the crust to a depth of about 2900 kilometers. Though solid, it deforms and flows due to high temperatures and pressures. It is thicker than both the crust and the core.
Explanation:The layer of Earth that possesses the greatest thickness is the
mantle
. This region of the Earth, situated underneath the crust, spans from the base of the crust down to a depth of approximately 2900 kilometers. It comprises the majority of the solid Earth. The mantle, although more or less solid, has the capacity to deform and flow slowly owing to the high temperatures and pressures present there. Its density progressively increases from about 3.5 g/cm³ at top to over 5 g/cm³ towards the bottom, a result of the compression produced by the weight it carries. The outermost layer is the crust, covering Earth's surface, but it is comparatively thinner with a variable thickness of 6 to 70 kilometers depending on whether it's oceanic crust (typically 6 km thick) or continental crust (20-70 km thick). Finally, beneath the mantle lies the dense metallic core, but even its combined sections (liquid outer core and solid inner core) do not exceed the mantle's vast thickness.

With increasing distance from a mid-ocean ridge, the age of oceanic crust _____.
The age of oceanic crust increases with increasing distance from a mid-ocean ridge, where new crust is formed and spreads outwards. The option (B) is correct.
With increasing distance from a mid-ocean ridge, the age of the oceanic crust increases. This is because new crust is formed at the mid-ocean ridges, and as it spreads outwards, it pushes older crust away from the ridge.
This process is symmetrical on either side of the ridge, with crust aging approximately 1 million years for every 20-40 km away from the ridge. The oldest oceanic crust is found to be up to 280 million years old in the eastern Mediterranean and around 180 million years in the open ocean of the North Atlantic.
This question is not complete, Here I am attaching the complete question:
With increasing distance from a mid-ocean ridge, the age of oceanic crust _____.

Remains or traces of organisms preserved in rock are called fossils.
What is the meaning of Fossils?The preserved remnants of plants and animals that were submerged in sediments like sand and mud beneath ancient seas, lakes, and rivers are known as fossils. Any preserved sign of life that is typically older than 10,000 years is considered a fossil.
Any surviving remains impression, or evidence of a once-living thing from a previous geological epoch is referred to as a fossil. Examples include exoskeletons, bones, shells, animal or microbe imprints in stone, items preserved in amber, hair, petrified wood, and DNA traces. The fossil record is the collection of all fossils.
The geologically changed remains of a formerly lived organism and/or its behavior are called fossils. Body fossils, which represent all or a portion of the organism's body, as well as trace fossils are the two main categories.

The tectonic plates are pressing against one another and creating the mountain, which is why the elevation has increased.
What is sedimentary layers?Beds or strata are the layers in which sedimentary rocks are deposited. A layer of rock with a consistent lithology and texture is referred to as a bed. Sedimentary layers are deposited on top of one another to create beds. Bedding refers to the pattern of beds that define sedimentary rocks.
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.
Sedimentary rocks are created by the accumulation of already existing rocks or fragments of extinct organisms on the Earth's surface. Deep burial of sediment causes it to get compressed and cemented, resulting in sedimentary rock.
