Answer:
Explanation:
The direction of longshore sediment transport is parallel to the shoreline. Longshore sediment transport refers to the movement of sand and other sediment along the beach or shoreline caused by the action of waves approaching the shore at an angle. When waves approach the shoreline at an angle, they generate a current that moves sediment in a zigzag pattern along the beach. This movement is known as the longshore current, and the sediment transport associated with it is called longshore sediment transport.
The direction of the longshore current and sediment transport is determined by the angle at which the waves approach the shore, as well as the shape of the coastline. The longshore current typically moves sediment from the up current end of the beach to the down current end. However, the direction of the longshore current can change depending on the angle of wave approach and the shape of the coastline. This sediment transport process is important in shaping the morphology of the coastline and in maintaining the balance between sediment erosion and deposition.

Were latitude the only control of temperature, the isotherms would run straight across the maps from east to west. Choose one region of the world where this hypothetical isotherm pattern is actually observed. Group of answer choices
Over the oceans
Over the continents
Over North Africa and the Sahara Desert
Over the oceans, since the water moderates temperature and creates more uniform conditions compared to the fluctuating temperatures over land. Therefore, the isotherms tend to run straight across the maps from east to west in oceanic regions.
However, this scenario is not observed in most regions of the world due to the presence of other factors that affect temperature variations, such as ocean currents, altitude, prevailing winds, and vegetation cover. As a result, the isotherms in different regions of the world follow complex patterns that reflect the interplay of these factors.
That said, the isotherms in oceanic regions tend to follow the hypothetical pattern mentioned above, running straight across the maps from east to west. This is because the large water bodies, such as oceans and seas, act as heat sinks that absorb and release heat more slowly than land surfaces. As a result, the temperature over oceans tends to be more uniform, with smaller variations between different latitudes. This creates a pattern of isotherms that are relatively straight, with a gradual decrease in temperature as one moves away from the equator towards the poles.
In contrast, over the continents, the temperature variations are much more pronounced due to the absence of large water bodies that can moderate the temperature. This leads to a more complex pattern of isotherms, which are influenced by factors such as altitude, prevailing winds, vegetation cover, and ocean currents in nearby regions.
Therefore, while the hypothetical pattern of isotherms running straight across the maps from east to west is not observed in most regions of the world, it is a characteristic feature of oceanic regions where large water bodies act as heat sinks to moderate temperature variations.

c. solid waste and synthetic pesticides.
d. excessive greenhouse heating.
Answer:
b. refined oil spills
Explanation:
Beacuse If oil spills in sea then marines cant go in ships
The most dangerous threat to the marine environment, overall, is probably excessive greenhouse heating. This is because rising temperatures can cause several problems for marine life. For instance, warming oceans can cause coral bleaching, which happens when coral reefs lose their vibrant colors and turn white.
Coral reefs are home to a vast array of marine species, and their destruction can have significant impacts on the ecosystem. Moreover, rising temperatures can cause an increase in the frequency and intensity of storms, leading to more coastal erosion and habitat destruction.
This can have harmful effects on the shells and skeletons of marine organisms, making it difficult for them to survive and reproduce. Acidification can also affect the food chain, as many species depend on these organisms for survival.
In conclusion, excessive greenhouse heating is the most significant threat to the marine environment, and urgent action is needed to address this problem. We must reduce our greenhouse gas emissions and take steps to mitigate the impacts of climate change on the ocean and its inhabitants.

During which of these two days does the air have a greater volume of water vapor? Show your work and justify your answer Day 1: Air Temperature. 86°F and RH 60% Day 2: Air Temperature: 41°F and RH-90% 26. Considering your answers for 1125, does a higher percentage for Relative Humidity always mean that there is more water vapor in the air? Explain
Answer:
Explanation:would a parcel of air at 35oc with a water vapor content of 17.5 g kg be saturated or unsaturated?
Would a parcel of air at 35 degrees C with a water vapor content of 17.5 g/kg be saturated or unsaturated? Explain your answer. Unsaturated. It would take water vapor content of 20 g/kg to saturate the air Unsaturated.
The lowest and highest outside relative humidity values would depend on various factors such as the time of day, temperature, and local weather conditions.
In general, relative humidity tends to be lowest during the warmest parts of the day when the air can hold more moisture, and highest during the cooler parts of the day or during periods of high moisture content in the air, such as during or after rainfall.
For question 26, a higher relative humidity does not necessarily mean that there is more water vapor in the air. The amount of water vapor that air can hold depends on its temperature and pressure, so a higher relative humidity may indicate that the air is nearing its saturation point, but not necessarily that there is more water vapor present.

Explain why we have seasons in detail and how the curved surface of the Earth makes a difference in climate.
Answer: Earth's seasons are caused by the tilt of the Earth's axis relative to its orbit around the sun, which leads to variations in solar radiation and temperature.
Explanation:
When the Earth is tilted towards the sun, as it is during summer in the northern hemisphere, that part of the Earth receives more direct sunlight and therefore more solar radiation. This leads to warmer temperatures, longer days, and shorter nights. Conversely, when the Earth is tilted away from the sun, as it is during winter in the northern hemisphere, that part of the Earth receives less direct sunlight and therefore less solar radiation. This leads to colder temperatures, shorter days, and longer nights.
The curved surface of the Earth also plays a role in climate. The curvature of the Earth means that different parts of the planet receive different amounts of solar radiation, depending on their latitude. Areas closer to the equator receive more direct sunlight and therefore more solar radiation than areas closer to the poles. This leads to warmer temperatures near the equator and cooler temperatures near the poles.
The curvature of the Earth also affects the circulation of air and ocean currents. Warm air near the equator rises and moves towards the poles, while cooler air near the poles sinks and moves towards the equator. This creates global wind patterns and ocean currents, which can influence climate and weather patterns around the world.

how much more intense is an earthquake of 8.6 magnitude compared to an earthquake of 4.5 magnitude? show all your work.
An earthquake of 8.6 magnitude is significantly more intense than an earthquake of 4.5 magnitude. In fact, it is about 31,623 times stronger in terms of energy released.
The Richter scale is logarithmic, which means that each whole number increase in magnitude represents a tenfold increase in amplitude and about a 32-fold increase in energy released.
Therefore, an earthquake of magnitude 8.6 has 1000 times greater amplitude than an earthquake of magnitude 4.5, and releases approximately 1000 × 1000 × 32 = 31,623 times more energy.
The Richter scale is used to measure the magnitude of earthquakes. It is a logarithmic scale that assigns a numerical value to the amount of energy released during an earthquake.
For example, an earthquake with a magnitude of 6.0 is 10 times more powerful than one with a magnitude of 5.0, and 100 times more powerful than one with a magnitude of 4.0. The scale ranges from 0 to 10, but in practice, earthquakes with a magnitude of 7.0 or higher are considered major earthquakes, and those with a magnitude of 8.0 or higher are considered great earthquakes.

the cycle of splitting of a supercontinent, opening of an ocean basin, followed by closing of the basin and collision of the continents, is known as a .
A "Wilson Cycle" is a series of events that involves the separation of a supercontinent, the opening of an ocean basin, the closing of the basin, and the collision of the continents.
The Wilson Cycle is named after J. Turo Wilson, a Canadian geophysicist who proposed the idea in the 1960s. It describes the process by which a supercontinent (such as Pangaea) breaks apart and separates into smaller landmasses, which then move away from each other and form new ocean basins. These ocean basins continue to widen as seafloor spreading occurs, until eventually the oceanic crust collides with a continental margin and begins to subduct.
The Wilson Cycle is a geologic concept that describes the formation, evolution, and eventual destruction of ocean basins. It starts with the breakup of a supercontinent due to plate tectonic processes, leading to the formation of a new ocean basin. As the ocean basin expands, new oceanic crust is created at the mid-ocean ridge.

explain the three possible strength types of rock (isotropic, transversely anisotropic and orthotropic), and give an example (rock name) of each one.
Rocks can have different strengths depending on their internal structure and the type of forces they are subjected to. The three possible strength types of rock are isotropic, transversely anisotropic, and orthotropic.
Examples:
Isotropic - granite and marble
Transversely anisotropic - shales and some sandstones
Orthotropic - slate and schist
Isotropic: An isotropic rock has the same mechanical properties in all directions. This means that it has the same strength and stiffness in all directions. Examples of isotropic rocks are granite and marble.
Transversely anisotropic: A transversely anisotropic rock has different mechanical properties in two perpendicular directions, but it is the same in the third direction. This means that it has different strengths and stiffnesses in the horizontal and vertical directions, but the same in the depth direction. Examples of transversely anisotropic rocks are shales and some sandstones.
Orthotropic: An orthotropic rock has different mechanical properties in three perpendicular directions. This means that it has different strengths and stiffnesses in the horizontal, vertical, and depth directions. Examples of orthotropic rocks are foliated rocks such as slate and schist.
