What is Thunderstorm ?

A thunderstorm, also known as an electrical storm or a lightning storm, is a type of storm in which lightning is present and produces the audible sound of thunder in the atmosphere of the Earth. Thundershowers are the name for relatively weak thunderstorms. A cumulonimbus is a form of cloud where thunderstorms develop. Strong winds are typically present along with them, and heavy rain, snow, sleet, or hail are frequently produced.

However, some thunderstorms result in little to no precipitation at all. A squall line, often known as a succession of thunderstorms, can form or become a rainband. Large hail, powerful winds, and tornadoes are just a few of the most hazardous weather events that may occur during strong or severe thunderstorms.

The east coast of United States is at high risk because of the presence of barrier islands, low elevation lands and gentle slopes of the coast.

The west Antarctic Ice sheet is collapsing at a faster rate due to the effect of Global Warming. This causes the ice to melt and an increase in the water level of the oceans and other water bodies. The east coast of the United States mainly comprises of the Atlantic Ocean and with the Atlantic Ice sheet melting it is the most vulnerable coast. The sea level if risen to an altitude greater than what is elevated then the people of the east coast will suffer. The presence of islands within the east coast which are called the barren islands provide the seawater a path to travel in the cities. Also, the area of the east coast is at a lower elevation, and this will provide no blockage to the rising seawater from flooding the cities. The slopes towards the coast are also gentle and not steep which will pave way for the seawater. All these reasons make the east coast most vulnerable.

Answer:

The magma forming process that creates andesitic lava is called fractional crystallization.

Explanation:

The magma forming process that creates andesitic lava is called fractional crystallization. This process happens when a magma chamber cools and crystallizes, and the different types of minerals that form crystallize at different rates. The slower-crystallizing minerals tend to sink to the bottom of the magma chamber, while the faster-crystallizing minerals rise to the top. When the magma is erupted, it is richer in the faster-crystallizing minerals, which gives it an andesitic composition.

Increased engagement with their lowland neighbors can be advantageous where the mountain communities have a strong sense of control over access to local resources and reliable local institutions.

Children and grandchildren of the poor mountain farmers who lived in the Tztal region of Austrian Tyrol in the early 20th century still hold ownership rights to the property they inherited, and they now run hotels and operate ski resorts.

Local pride and a sense of independence made sure that local culture was preserved, if not really improved.A "neo-Tyrolian" aesthetic has resulted as a result, and it is now the main draw for tourists from the lowland and urban hinterland.

However, as Moser and Moser (1986) show, there have been major expenditures involved, as well as detrimental social and environmental effects, including the widening of the economic divide between successful business people and those who continue to farm.

Ironically, traditional farming methods must continue in order for the ecology to remain stable and for tourists to perceive the area as beautiful, which is crucial for summertime economic success.

Pre-existing rocks or fragments of extinct species serve as the building blocks for sedimentary rocks. They develop from deposits that build up on the surface of the Earth. Sedimentary rocks frequently exhibit recognizable bedding or layering.

Sedimentation is the process through which sedimentary rocks are created. Sedimentary rocks fall into one of three categories.

The construction of levees is why the river reached this condition.

what is a flood plain?

A relatively flat region of land near a river or stream is referred to as a floodplain (or floodplain). It extends from the river's banks to the valley's outer reaches. A floodplain is divided into two sections. The first is the floodway, which is the river's main channel.

A levee is a dam with a specific function: to guard against floods caused by seasonally high water. Levees are vulnerable to water loading for only brief periods each year, ranging from a few days to a few weeks, unlike small earth dams. They must therefore be created and designed using levee-specific standards.

Ephemeral streams are not fed by groundwater.

What are  Ephemeral streams?

A transient stream that only runs for a short time as a direct result of precipitation is called an ephemeral stream. It mostly occurs in dry and semi-arid areas with intermittent rainfall. In contrast to intermittent streams, it lacks a diverse morphological channel or bed.

Precipitation happens relatively seldom in dry or semi-arid areas. As a result, when enough rain does fall, it frequently creates a transient stream on the surface.

The stream may forge a brand-new route or follow an already-created channel (also known as a dry wash) left behind by earlier ephemeral streams.

Soft engineering is where the natural environment is used to help reduce coastal erosion and river flooding. At the coast, soft engineering is where a beach is used to absorb wave energy and reduce erosion. Through hard coastal protection strategies, we try to work against natural interactions in order to protect certain eras. Soft coastal protection strategies are methods to secure and/or restore coastal lines through a body of sand.

Explanation:

Mantle convection transports heat from the mantle's depths to the surface, where the heat is released to create the oceanic crust-creating magmas.

What is Mantle convection?

Convection, a thermally driven process whereby deep heating causes material to expand and become less dense, leading it to rise while being replaced by complementary cool material that sinks, is the primary method of heat transport in the Earth's mantle. Because the material that rises releases heat as it rises and cools, and the material that sinks acquires heat only to eventually rise again, this cycle of heat transfer from depth to the surface is particularly effective. Convection, together with conduction, radiation, and advection, is the most significant mechanism by which the Earth loses heat. However, the plate tectonic cycle combines a lot of these mechanisms.

Mantle convection transports heat from the mantle's depths to the surface, where the heat is released to create the oceanic crust-creating magmas.

Active hydrothermal circulation and heat loss occur along the midocean ridge axis, creating vents like black smoker chimneys. The crust and lithosphere eventually sink to a depth of 1.5–2.5 miles (2.5–4.0 km) below sea level as they move away from the midocean ridges and cool through conduction. The primary process of plate tectonics is consequently heat loss by mantle convection, and moving plates can be viewed as the conductively cooling boundary layer for large-scale mantle convection systems.

Convection heat is produced by the decay of radioactive elements, including potassium 40, uranium 235, and thorium 232. It is also produced by leftover heat from the Earth's early formation, including iodine 129, leftover heat from meteorite and asteroid impacts, and leftover heat from the Earth's core formation.

The Earth has been cooling via convection ever since the mantle of the planet was at least partially molten early in its history. Although it is difficult to gauge how much the mantle has cooled through time, reliable estimates indicate that the mantle may have been several hundred degrees hotter in the earlier Archean.

Part C of the following diagram shows an oceanic- oceanic convergent boundaries.

A convergent boundary is a spot-on Earth where two or more lithospheric plates collide. One plate will always slide under another during subduction. Ocean-ocean, ocean-continent, and continent-continent are the three different forms of convergent boundaries.

Oceanic-continental convergent borders are created when tectonic plates with primarily oceanic lithosphere collide with plates with primarily continental lithosphere.

Compared to the continental lithosphere, the crust is denser because it has more minerals rich in iron and magnesium. The oceanic lithosphere plate will buckle beneath the continental plate and plunge into the warm asthenosphere when these two very distinct plates intersect. Subduction is the term for this action. The melting occurs as the subducting plate is pushed further into the mantle. This generates magma, which rises and erupts. This creates an island arc, a line of volcanoes. Examples of island arcs include Japan, Indonesia, the Philippines, and the Aleutian Islands of Alaska.
