The current flowing parallel to and just offshore of a beach is called the longshore current. It is a narrow current that moves parallel to the shoreline and is generated by waves approaching the shore at an angle.
When waves strike a shore obliquely, the water near the shore is pushed up the beach at an angle and then returns to the sea perpendicular to the beach. This backwash of water is then carried by gravity back down the slope of the beach. The process of water moving up the beach at an angle and then returning down the slope perpendicular to the beach is known as swash. This movement of water generates the longshore current, which moves parallel to the beach in the direction of the swash.
The longshore current can be powerful and can carry swimmers and surfers down the beach, away from where they started. Beachgoers should always be aware of the dangers posed by longshore currents and should never swim alone or without supervision.

name and describe each version of natural selection on polygenuic traits.
Natural selection on polygenic traits refers to the evolutionary process where the genetic variation of multiple genes influences the fitness of individuals in a population.
It occurs through two main mechanisms: stabilizing selection and directional selection. Stabilizing selection favors intermediate phenotypes, reducing genetic variation by selecting against extreme traits. In contrast, directional selection favors individuals with extreme phenotypes, causing a shift in the average trait value over time. These two forms of selection act on polygenic traits and play significant roles in shaping the genetic diversity and adaptation of populations.
Natural selection on polygenic traits involves the selection pressures acting on traits controlled by multiple genes. Polygenic traits are characterized by continuous variation, where individuals in a population display a range of phenotypes. Stabilizing selection is one form of natural selection on polygenic traits. In this process, the average phenotype within a population is favored, leading to a reduction in genetic variation. Stabilizing selection occurs when intermediate phenotypes have the highest fitness, while extreme phenotypes are selected against. As a result, the genetic diversity of the population is maintained around the mean value of the trait, and the population becomes well-adapted to its current environment.
Directional selection is another type of natural selection on polygenic traits. Unlike stabilizing selection, directional selection favors individuals with extreme phenotypes, causing a shift in the average trait value over successive generations. This shift occurs when one extreme of the phenotypic range confers a greater fitness advantage compared to the other extreme or intermediate phenotypes. Over time, the population exhibits a gradual change in the average value of the trait due to the consistent selection pressure acting on one direction.
Both stabilizing and directional selection are important mechanisms in the evolution of polygenic traits. Stabilizing selection maintains the status quo by favoring intermediate phenotypes and reducing genetic variation, while directional selection drives evolutionary change by favoring extreme phenotypes and causing shifts in trait values.
These processes contribute to the adaptation and diversification of populations over time, allowing them to better survive and reproduce in their respective environments.

how is poor infrastructure a cause of drought pls try and explain
Answer:
We can't store water.
Explanation:
Poor infrastructure is a cause of drought conditions because we are unable to store water to fulfill our water needs. Infrastructure helps us to store water that comes from surface runoff such as rivers streams, lakes and rainfall. If we have dams and reservoir, we can store this water and overcome drought conditions by providing this water to the plants as well as to the animals and humans for drinking purpose so we can conclude that poor infrastructure is responsible for the drought condition.

during day three there is a lot of geological activity what rocks are formed
According to the biblical account of creation in Genesis, on the third day, God created the dry land and the plants.
Volcanic activity would have dominated rock creation throughout the early stages of Earth's history, as molten rock (magma) from the Earth's mantle would have been driven to the surface and hardened as igneous rocks. These rocks would have served as the foundation for the continents and oceanic crust.
The forces of erosion and weathering would have began to sculpt the landscape as the Earth's surface cooled and hardened, breaking down the volcanic rocks into smaller particles and depositing them in the form of sedimentary rocks.
Sandstone, shale, limestone, and other forms of rock created by the deposition of sediment and other particles would have been among the sedimentary rocks.

how many spring tides occur in the time it takes the moon to make one complete orbit around earth?
In the time it takes the moon to make one complete orbit around Earth, there are approximately 12.37 spring tides.
A spring tide occurs when the sun, moon, and Earth are aligned in a straight line, creating a gravitational pull that results in higher than normal tides.
The time it takes for the moon to complete one orbit around Earth is approximately 27.32 days, known as the sidereal month.
However, due to Earth's rotation around the sun, it takes slightly longer for the moon to return to the same phase in relation to the sun, known as the synodic month, which is approximately 29.5 days.
During this time, the position of the moon in relation to the sun and Earth changes, resulting in varying gravitational pulls that affect the tides. Spring tides occur twice a month, during the full and new moon phases, when the sun, moon, and Earth are in alignment.
Therefore, there are approximately 24.74 spring tides in a year, or 12.37 spring tides in the time it takes for the moon to make one complete orbit around Earth.
It's important to note that while spring tides result in higher than normal tides, they do not necessarily cause flooding or other coastal hazards. Other factors, such as storms and local topography, can also play a role in the severity of coastal events.

what is the pattern of regional surface winds around the center of a low-pressure system in the northern hemisphere?
The pattern of surface winds around a northern hemisphere low-pressure system is counterclockwise.
The Coriolis force, which acts in the opposite direction in the northern hemisphere around areas of low pressure and in the other direction around areas of high pressure, causes this wind spiral to flow in the opposite direction in the southern hemisphere.
East-west winds, as opposed to north-south winds, are more common. The Coriolis effect, which is brought on by the Earth's rotation, is what causes this to happen. The Coriolis effect causes wind systems to rotate anticlockwise in the Northern Hemisphere and clockwise in the Southern.

list three factors that determine the size of a wave
The size of a wave is determined by three main factors: wind speed, duration of wind, and fetch.
Wind Speed: The speed of the wind directly affects the size of a wave. The stronger the wind, the larger the waves it can generate. Higher wind speeds create greater surface friction and transfer more energy to the water, resulting in larger waves.
Duration of Wind: The duration of wind blowing over a body of water is another crucial factor. Waves continue to grow as long as the wind persists. If the wind blows consistently for a prolonged period, it allows more time for the energy to transfer to the water, leading to larger waves.
Fetch: Fetch refers to the distance over which the wind blows uninterrupted over a body of water. A longer fetch allows waves to build up and gain more energy. As the wind blows over a larger stretch of water, waves have more time and space to develop and grow in size.
These three factors work together to determine the size of waves in a particular area. However, it's essential to note that other factors, such as water depth, current patterns, and underwater topography, can also influence wave size in specific regions.

.Horizontal shear stresses, like those pictured, may produce ______.
strike-slip faults in shallow parts of the crust
metamorphism and ductile deformation at depth
shear zones
Horizontal shear stresses may produce a combination of strike-slip faults in shallow parts of the crust, metamorphism and ductile deformation at depth, and shear zones.
In shallow parts of the Earth's crust, horizontal shear stresses can lead to the development of strike-slip faults. These faults occur when rocks on either side of a fracture move horizontally relative to each other. They are common in areas where tectonic plates are sliding past one another, such as in the San Andreas Fault system.
At greater depths within the crust, where temperatures and pressures are higher, horizontal shear stresses can cause metamorphism and ductile deformation. Metamorphism refers to the transformation of rock due to changes in temperature, pressure, or the presence of fluids. In this context, ductile deformation describes the process where rocks bend, stretch, or flow under stress without fracturing. This type of deformation is more likely to occur at depth, as the higher pressures and temperatures allow for increased plasticity in the rock.
Shear zones are another feature that can be produced by horizontal shear stresses. These zones are characterized by highly deformed rock that has experienced significant shear strain, often resulting from the movement of tectonic plates. Shear zones can be associated with both strike-slip faults and ductile deformation, depending on the specific geologic conditions and depth at which they occur.
