Two predictive methods to reduce the impact of coastal flooding are natural dune system and seawalls.
What is a Seawall?
A seawall is a type of coastal defence built where the water and related coastal processes directly affect the coastline's landforms. A seawall is built to shield populated regions, natural areas, and recreational places from the effects of tides, waves, and tsunamis. In order to shield the inland region from wave action and stop coastal erosion, a seawall is a structure composed of concrete, masonry, or sheet piling that is built parallel to the shore at the transition between the beach and the mainland or dune. A seawall is often a large structure built to withstand storm surges.

describe what happens to the tectonic plates along a transform boundary during the time between earthquakes.
Using the theories of tectonic plates, we got that during the time between earthquakes the tectonic plates lock into the place to prevent from sliding causing pressure to build up.
Plates can move past each other in same plane at a boundary. This type of the boundary is called a transform boundary. This type of the boundary is dominated by strike-slip faulting, although other types of the faulting may be observed, where the two plates slide past each other, earthquakes originate at shallow depths.
Hence, during the time between earthquakes tectonic plates along a transform boundary lock into the place to prevent from sliding causing pressure to build up.

Grade 9 boys went for a school tour to a hill station ooty in tamil nadu. what will be the temperature at the foothills? what will be the temperature at the top of the hill station?
The temperature on the foothills will be hot, while the temperature at the top of the hill will be cooler.
The altitude of a place can factor in temperature conditions. This is related to the relationship between temperature and air pressure.
The higher we are above sea level, the lower the air pressure. In conditions with low air pressure, air molecules will move more slowly, so no collisions between air molecules occur. As a result, less heat is created, the temperature will feel cooler. Conversely, the lower it approaches sea level, the higher the air pressure which creates a hotter temperature due to the denser air molecules.
This means that grade 9 boys will feel the temperature at the top of the hill station will feel colder than the temperature when grade 9 boys are in the foothills.

When does a volcano occur?
Answer:
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Magma is lighter than rock so rises towards the Earth's surface.
Explanation:
Why and how do volcanoes actually erupt?
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.
Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another.
Magma is lighter than rock so rises towards the Earth's surface. As the magma rises, bubbles of gas form inside it.
Runny magma erupts through openings or vents in the earth's crust before flowing onto its surface as lava.
If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises.
When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.
Another way an eruption happens is when water underneath the surface interacts with hot magma and creates steam,
this can build up enough pressure to cause an explosion.

groundwater in constricted fractures is heated past its surface boiling temperature by surrounding hot rocks. the superhot liquid expands in volume, reducing its confining pressure, and flashing it into steam. which geologic feature matches this description?
Geysers are a type of hot spring that periodically erupts water and steam. The word geyser comes from the Icelandic word "geysa" which means "to gush". Geysers are formed when groundwater is heated past its surface boiling temperature by surrounding hot rocks.
The super-hot liquid expands in volume, reducing its confining pressure, and flashing it into steam. The steam then rises and escapes through the opening at the surface, causing the characteristic eruption.
Geysers are found only in certain areas where the water table is heated by a hot magma chamber below the earth’s surface. The most famous geysers are found in Yellowstone National Park in the United States.
Old Faithful is perhaps the most famous geyser in Yellowstone. It is not the biggest or the most regular geyser in the park, but it is the most predictable, erupting every 35 to 120 minutes, shooting a column of water up to 80 feet (24 meters) in the air.

at what depth does metamorphism start in the earth's crust if the surface is 25 degrees celsius, the geothermal gradient is 25c/km, and metamorphism starts at 200c?
Temperature and pressure can become so extreme at a particular depth that they can change the chemical makeup, texture, or mineralogy of rocks. The transformation of rocks is known as metamorphism.
At a depth of 10 to 30 km, the middle and lower crust produces the majority of metamorphic rocks. The rate at which the temperature of the Earth rises with depth is known as the geothermal gradient. It suggests that the Earth's surface is receiving heat from the planet's warm center. For every kilometer of depth, the temperature rises by about 25°C on average. Such magma bodies heat the surrounding rock to a temperature of about 1000 °C, causing contact metamorphism (Figure 7.19). In the absence of directed pressure, this occurs at very shallow depths, hence the resulting rock typically does not foliate. Tectonic forces, like the collision of two continental masses, frequently cause compressional stresses in the rocks, which cause the differential stress. Consequently, the cores of fold-and-thrust mountain belts or eroded mountain ranges are where regionally metamorphosed rocks are found. As far as metamorphic processes go, burial metamorphism occurs at pressures and temperatures that are relatively low (up to 300 °C).

(c) pressure decreases with height in the troposphere on the four giant planets. (d) temperature increases with height in the stratosphere on the four giant planets.
The statement (c)pressure decreases with height in the troposphere on the four giant planets is false .
How does the pressure change in the troposphere?
For every thousand feet of height above sea level, the atmospheric pressure in the troposphere decreases by around one inch of mercury.
As you go to greater altitudes, the density (and pressure) of the air steadily decreases because the earth's gravity keeps our atmosphere near to the surface. Atmospheric pressure is around 30 inches of mercury at sea level and drops by about an inch for every thousand feet of elevation above sea level, or about 26 inches of mercury at an altitude of 4000 feet.
The impacts of weather are most noticeable in the troposphere, where temperature and the presence of high- and low-pressure weather systems affect real pressure.

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;

During metamorphism, changes in the bulk composition of a rock occur primarily as a result of reaction with hydrothermal fluids.
What is the process of metamorphism ?
Earliest metamorphic, sedimentary, or igneous form. When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, any combination of these conditions, metamorphic rocks are created. These kinds of conditions can be found deep below the Earth or when tectonic plates collide.
The process of metamorphism changes the rocks into denser, more compact rocks rather than melting them. Either by the rearranging of mineral constituents or through chemical interactions with fluids that enter the rocks, new minerals are produced. Even rocks that have already undergone metamorphosis might undergo changes due to pressure or temperature. Rocks subject to metamorphism are frequently crumpled, smeared, and compressed. Metamorphic rocks do not grow hot enough to melt because if they did, they would turn into igneous rocks.

which type of volcanic eruption exhibits explosion or fountain of basaltic lava from a single vent
Hawaiian eruption exhibit an explosion or fountain of basaltic lava from a single vent
What is Hawaiian eruption?
Because it is typical of Hawaiian volcanoes, a Hawaiian eruption is a particular kind of volcanic eruption in which lava flows out the vent in a relatively calm, low-level explosion. Typically, these are effusive eruptions with basaltic magmas that are hot near the vent, low viscous, and low in gases. Volcanic ash is only occasionally produced. This kind of eruption can happen close to subduction zones and rift zones, although it most frequently happens at hotspot volcanoes like Kilauea and Iceland. On Surtsey from 1964 to 1967, molten lava flowed from the crater to the sea as another example of Hawaiian eruptions.
Hawaiian eruptions can happen along fissure vents, as they did during the 1950 eruption of Mauna Loa Volcano, or at a central vent, as they did in 1959 during the Kilauea Iki Crater eruption, which produced a lava fountain 580 metres high and constructed a 38-meter cone known as Pu'u Puai. Lava spurts from a fissure on the rift zone of the volcano feed lava streams that flow downslope during fissure-type eruptions. Lava fountains can erupt from core vent eruptions to a height of 300 metres or higher.
