True ,seawalls are constructed perpendicular to the shore to prevent wave erosion.
What is wave erosion ?
Waves may erode beaches on a variety of geographical and temporal dimensions. A scour zone moves up the beach or down the beach with every rise and fall in the tide. At the tide level, there is a turbulence zone where suspension of sediment is common. It is also the zone where the backwash meets the oncoming surge.
The erosion occurs between three percent and forty percent of the breaker height and deeper. As the tides vary, the breaker zone likewise moves down the beach. Sediment migration in the foreshore-inshore region is highest within the breaking zone. In actuality, the breaker zone is where nearly 50% of the sediment flow occurs.

A semidiurnal tidal cycle exists on the east coast of the united states, which experiences two high tides and two low tides of similar heights every day
What is the Semidiurnal tidal cycle?
Every lunar day, there are two almost identical high tides and low tides, which is known as a semidiurnal tidal cycle. Their wavelength is greater than half the Earth's radius, and they have a period of 12 hours and 25 minutes
Additionally, it is the kind of tidal cycle one would anticipate from a planet fully covered in water and devoid of any continents to hinder the free flow of water.
Semidiurnal tides, or twice-daily high and low tides, are common along most shorelines. The more or less terrestrial to entirely marine conditions in the intertidal zone thus change twice daily, creating a strong vertical gradient of environmental element

depositional environments for sedimentary rocks can be deduced by look at sedimentary structures, like the giant cross-stratified navajo sandstone exposed in zion national park. to what do these dipping cross-bedded layers owe their origin?
These dipping cross-bedded layers blow Wind into sand dunes in the desert.
What are sand dunes?
A dune is a wind-formed sand mound that typically forms near a beach or in a desert. Sand accumulates in dunes when the wind drives it into a protected region behind a barrier. Sand grains build up to form dunes.
Every dune has a slip face and a windward side. The side of a dune that is windward is where the wind is blowing and pushing debris upward. Simply put, a dunes slip face is the unwinding side. In general, a slip face is more level than a dune's windward side.
A dune field or dune belt is a grouping of dunes. An erg is a sizable dune field. Namibia's Skeleton Coast Erg measures 20 kilometres in width and 2 to 5 kilometres in length.
Strong currents in the water below the surface can also create dunes. Subaqueous dunes, also known as underwater dunes, are typical in the ocean, rivers, and canals.

the polar position hypothesis suggests that glaciers should form on earth when continents exist in polar regions. however, from 125-35 ma (~cretaceous period), there were continents at the poles but no glaciers. why?
The most famous of the several climatic indicators that support continental drift is glacial activity.
When Alfred Wegener looked into this area, he discovered an anomaly inside the Permo-Carboniferous ice sheet, which previously covered all of the southern main plates and was discovered through glacial till layers.
It was first proposed that arctic ice should occur on continental when they were situated in polar or closely adjacent to polar regions. There shouldn't be any ice anyplace on Earth if there are no continents close to the South or North Poles.

Upwelling is the oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually the nutrient-rich water from deep water towards the ocean surface. It replaces warmer and usually nutrient-depleted surface water. The nutrient-rich upwelled the water stimulates the growth and reproduction of primary producers such as the phytoplankton.

What are the limitations of using historical records as a means of predicting seismic activity?
A major earthquake has never been predicted by the USGS or any other scientist. We don't know how, and we don't expect to find out any time soon. USGS scientists can only calculate the likelihood of a significant earthquake occurring in a specific area (as shown on our hazard mapping) within a certain number of years.
A prediction of an earthquake must include three elements: 1) the date and time, 2) the location, and 3) the magnitude.
Yes, some people claim to be able to predict earthquakes, but their claims are false for the following reasons:
They are not founded on scientific evidence, and earthquakes are a natural occurrence. Earthquakes, for example, have nothing to do with clouds, bodily aches and pains, or slugs.
They do not define all three elements necessary for prediction. Their predictions are so broad that there will always be an earthquake that fits;

What is a violent rotating column of air in contact with the ground, usually associated with a thunderstorm?.
Typically, a tornado is a violently rotating column of air that touches the ground and is at the base of a thunderstorm. Tornadoes are the most intense storms in nature. Tornadoes, which are spawned by intense thunderstorms, can wreak deaths and ruin an entire neighborhood in seconds. A tornado's winds may reach 300 miles per hour.
As rising air within the thunderstorm deflects the rotating air from horizontal to vertical, the region of rotation now encompasses a significant portion of the storm. A tornado can occur when the updraft is whirling and is nourished by warm, moist air rising from the ground.
Every thunderstorm has the capacity to create tornadoes, but the supercell is the most frequently tornadic storm category. This extremely intense, long-lasting thunderstorm has circulation aloft (mesocyclone) that expands upward and downward throughout the storm.
Destruction and injuries inflicted by a tornado are dependent on its intensity, size, course, time of day, and duration on the ground. Tornadoes can generate winds in excess of 200 miles per hour, and damage pathways can be more than one mile wide and fifty miles long.
