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.

Water that would typically have been trapped in the snowpack will now fall as liquid, increasing the amount of fresh water that is readily available.
What is precipitation?Any type of moisture that falls to the earth is referred to as precipitation. This covers hail, sleet, snow, and rain.
Water vapour condenses into precipitation when it cools. The water vapour condenses and turns into minute droplets of water when the air hits saturation point, also referred to as condensation point and dew point. These minute water drops from clouds.
The water droplets fall as rain as a result of complicated dynamics. Rain is rain is rain. It occurs as a result of cooling warm, wet air, which causes condensation and eventually rain. The three methods of air cooling that result in rainfall are demonstrated in the following instances.

Determine the missing length in the right triangle using the Pythagorean Theorem. Simplify the squareroot
A wise response is to choose (a). The length that is missing from the right triangle according to the Pythagorean Theorem is equal to √117.
The Pythagorean theorem is what?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Using the sum of the areas of three intersecting squares, the Pythagorean Theorem shows how to get the side lengths of a right triangle. This theorem is an extremely useful technique that forms the basis for more complicated trigonometry concepts like the inverse of the Pythagorean theorem.
What is the Pythagoras Theorem's exact formula?Assume that the triangle ABC has sides measuring a, b, and c, and that [tex]a^{2} + b^{2} = c^{2}[/tex]. A second triangle with sides of lengths a and b and a right angle should be built. The hypotenuse of this triangle has length c = √[tex](a^{2} + b^{2})[/tex], matching the length of the hypotenuse of the first triangle according to the Pythagorean theorem.
We will use the Pythagorean Theorem to the following problem to identify the right-angled triangle's missing side.

which of the following are types of oil traps? choose one or more: a.pits b.anticlines c.faults d.salt domes
Anticlines, faults, salt domes are some oil traps
What is Anticlinal trap?
An area of the subsurface where the strata have been forced into producing a dome shape is known as an anticline. If such a dome-shaped layer of impermeable rock exists, hydrocarbons can build up at the crest until the anticline is filled to the spill point, which is the highest point from which they can escape. The hydrocarbon sector considers this kind of trap to be by far the most important. Look at a geological map or fly over the area to spot anticline traps, which are typically long oval land domes.
What is a Fault trap?
The shifting of impervious and permeable rock strata along a fault line created this trap. The impermeable rock now abuts the permeable rock of the reservoir, blocking further hydrocarbon migration.
In some circumstances, an impermeable material (like clay) may be smeared along the fault line, which also serves to inhibit migration. It's called a clay smear.
What is a sold dome trap?
Due to their increased buoyancy, masses of salt are driven up through clastic rocks, finally breaking through and rising towards the surface (see salt dome). This salt is impermeable, and when it passes through a layer of permeable rock through which hydrocarbons are migrating, it obstructs the channel in a manner similar to that of a fault trap. This is one of the factors contributing to the considerable interest in subsalt imaging, despite the numerous technological difficulties that come with it.

Explanation:
What is a violent rotating column of air in contact with the ground, usually associated with a thunderstorm?.
Tornado
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.

How does the movement of tectonic plates shape the earth's surface?
Answer:
Plate motions cause mountains to rise where plates push together or converge, and continents to fracture and oceans to form where plates pull apart or diverge. The continents are embedded in the plates and drift passively with them, which over millions of years results in significant changes in Earth's geography.
Explanation:
Principles of plate tectonics
Earth's lithosphere and upper mantle
Earth's lithosphere and upper mantle
In essence, the plate-tectonic theory is elegantly simple. Earth’s surface layer, 50 to 100 km (30 to 60 miles) thick, is rigid and is composed of a set of large and small plates. Together, these plates constitute the lithosphere, from the Greek lithos, meaning “rock.” The lithosphere rests on and slides over an underlying partially molten (and thus weaker but generally denser) layer of plastic partially molten rock known as the asthenosphere, from the Greek asthenic, meaning “weak.” Plate movement is possible because the lithosphere-asthenosphere boundary is a zone of detachment. As the lithospheric plates move across Earth’s surface, driven by forces as yet not fully understood, they interact along their boundaries, diverging, converging, or slipping past each other. While the interiors of the plates are presumed to remain essentially undeformed, plate boundaries are the sites of many of the principal processes that shape the terrestrial surface, including earthquakes, volcanism, and orogeny (that is, the formation of mountain ranges).

Surface features that are created when water dissolves limestone, like sinkholes and disappearing streams, are parts of a karst landscape .
What is meant by Karst landscape ?
A karst landscape is one in which sinkholes, sinking streams, caverns, springs, and other distinctive characteristics have been produced as a result of the bedrock's erosion. Karst is connected to soluble rock types including gypsum, marble, and limestone. A typical karst environment develops when a significant amount of surface water interacts with the subsurface and enters through fractures, holes, and crevices that have been dissolved into the bedrock.
The karst region is perfect for retaining water as an aquifer and offers a plentiful supply of pure drinking water to people, plants, and animals. Karst is porous (like Swiss cheese), which allows water to pass through it fast with little filtering. As a result, pollutants that enter a karst aquifer are quickly transported, leading to issues with water quality.
