Using the theories of shoreline, we got that longshore current is turbulent water current that carries sand and flows within the surf zone parallel to the shoreline.
Hard shoreline stabilization includes the various fixed, immovable structures designed to hold an eroding shoreline in the place. Hard stabilization is one of the most common modifiers of the topography in the coastal zone and is discussed further more detail below. Seawalls, jetties, groins, and offshore the breakwaters interrupt sediment exchange and reduce shoreline flexibility to respond to the wave and tidal actions. Armoring the shoreline changes the location and intensity of the erosion and deposition. Indirectly, hard shoreline stabilization gives the false sense of security and encourages increased development landward of walls, placing more and more people and property at risk from the coastal hazards including waves,
Hence, sand that is carried by turbulent water currents that flow within the surf zone parallel to the shoreline are called longshore currents.

approximately how often do locked segments of the san andreas fault (california) break, resulting in major earthquakes?
Approximately once every hundred and fifty years locked segments of the san andreas fault break, resulting in major earthquakes .
What is meant by Earthquakes ?
An earthquake is the shaking of the Earth's surface caused by a rapid release of energy in the Earth's lithosphere, which generates seismic waves. It is also referred to as a quake, tremor, or temblor. Earthquakes can range in strength from those that are so little that no one can feel them to those that are powerful enough to throw things and people into the air, destroy vital infrastructure, and devastate entire cities.
The number, kind, and size of earthquakes that occur in a region during a specific time period is known as its seismic activity. The average rate of seismic energy release per unit volume is what is known as seismicity at a certain region on Earth. Tremors, which are not earthquakes, are also referred to as seismic rumbling.

channel beds erode faster than channel sides in ____ streams and rivers. - highly turbukent - high velocity - high gradient.
Channel beds erode faster than channel sides in high velocity streams and rivers. A smooth channel has less friction than a rocky or boulder strewn channel, so it moves faster.
The velocity of a stream is thus greatest in a narrow, deep, smooth, semicircular channel. Flow velocity. The velocity of a stream is the rate at which it flows. In high velocity streams and rivers, channel beds erode faster than channel sides. Because of the steep slope, a mountain stream moves quickly. This results in a lot of erosion and little deposition.

The correct answer is Much more sand piled up on the beach relative to the end of the winter season. This occurs during summer season.
A beach is a landform made up of loose materials that is located next to a body of water. Sand, gravel, shingle, pebbles, and other types of rock or biological materials, such as mollusk shells or coralline algae, are often the materials that make up a beach. Depending on the local wave activity and weather, sediments settle in varied densities and structures, resulting in different textures, hues, and gradients or layers of material. Despite the fact that some beaches develop on inland freshwater settings like lakes and rivers, the majority of beaches are found along the coast, where wave or current activity deposits and reworks sediments. Natural processes like wave action and severe weather events cause erosion and change in the geology of beaches.

Answer:The right response is Substantially more sand heaped onto the ocean side comparative with the finish of the colder time of year season. This happens during summer season.
An ocean side is a landform comprised of free materials that is situated close to a waterway. Sand, rock, shingle, stones, and different kinds of rock or natural materials, for example, mollusk shells or coralline green growth, are in many cases the materials that make up an ocean side. Contingent upon the nearby wave movement and climate, dregs get comfortable shifted densities and designs, bringing about various surfaces, tones, and slopes or layers of material Substantially. Regardless of the way that a few sea shores foster on inland freshwater settings like lakes and streams, most of sea shores are tracked down along the coast, where wave or ebb and flow action stores and modifies dregs.

Changes in climate affect the sea level by:
About 90 percent of the heat generated by increased emissions has been absorbed the sea level. As the extra heat and energy warm the ocean, the change in temperature results in unprecedented cascading effects, such as ice melting, sea level rise, marine heatwaves, and ocean acidification.
Influence of sea level rise on human populations:
Due to flooding and erosion, human populations and other species are displaced. Coastal flooding increases groundwater salinity, which diminishes freshwater quality and availability and soil quality. This has repercussions for agricultural produce and cattle. The prevalence of coastal ecosystems.

State a probable period of revolution of the planet
Thelma using proper units.
The period of revolution of the planet Thelma using proper units is 365 Days.
The planets' rotation is not induced by any external force. The conservation of angular momentum is primarily responsible for rotation. L=m*w*r2 is the formula for angular momentum, where m stands for mass, w for angular velocity in radians per second, and r for the circumference of the circular motion.
As the planet gets farther from the sun, the period of revolution lengthens. Neptune therefore has the longest revolution period. Seasons, aphelion, and perihelion are all effects of the revolution on earth. The apogee is the distance between the earth and the sun. The earth is closest to the sun at perihelion.

The greenhouse effect on Venus's surface environment is to increase the planet's surface temperature by hundreds of degrees Celsius (460° C).
The Effect of the Greenhouse Effect on the Planet VenusVenus is a planet that has a very high concentration of greenhouse gases (especially carbon dioxide). This greenhouse effect causes the surface temperature of the planet Venus to reach 460° C, making it very inhospitable for living things to inhabit.
Other planets that have a greenhouse effect include Venus, Mars, and Saturn's largest satellite. Venus' atmosphere is composed mostly of carbon dioxide, trapping radiation that would be re-emitted into space and causing its surface temperature to be higher than Mercury's (given the fact that Mercury is closer to the Sun than Venus).
