Answer: A.Unlike lava, pyroclastic material erupts onto Earth’s surface.
Explanation:
The pyroclastic material is the one that erupts with an explosive volcanic eruption like that of lava eruption. The pyroclastic erupts by ejecting the fragments, resulting in ashfall deposits, it flows out with an ash deposit on the surface of the earth. The fragmented material spreads on the Earth's surface. The fragments are of grain size.

An earthquake is best described as a
Answer:
a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
Explanation:
An earthquake is the shaking of the Earth's surface caused by a sudden release of energy in the Earth's lithosphere, which generates seismic waves.
What is Earthquake ?It is also referred to as a quake, tremor, or temblor. Earthquakes can range in strength from those that are so small 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 over 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 specific region on Earth.
Tremors, which are not earthquakes, are also referred to as seismic rumbling. Earthquakes cause the ground to shake, move, or otherwise be disturbed at the Earth's surface. The bottom may be sufficiently moved to generate a tsunami when a big earthquake's epicenter is offshore. Landslides can also be brought on by earthquakes.

Estimate the distance of a fading white dwarf supernova of luminosity 108lsun whose apparent brightness is comparable to that of a bright cepheid variable star 100 million light-years from earth.
Answer:
The supernova is a fraction of 0.7 of the size of the observable universe which is 10 billion light years away.
Explanation:
Apparent brightness(AB) = luminosity(L) / 4πr²
∴ Luminosity(L) = Apparent brightness(AB) × 4πr²
Ratio of the luminosity of cepheid and supernova with the same brightness will be written as;
[tex]\frac{L_{cepheid}}{L_{supernova}} = \frac{AB_{cepheid}(4\pi r^2)}{AB_{supernova}(4\pi r^2)}[/tex]
[tex]= \frac{AB_{cepheid}(r^2_{cepheid})}{AB_{supernova}(r^2_{supernova})}[/tex]
[tex]\frac{(r^2_{cepheid})}{(r^2_{supernova})}[/tex]
Therefore, [tex]r_{supernova} = r_{cepheid}\sqrt{\frac{luminosity_{cepheid}}{luminosity_{supernova}} }[/tex] ...................(a)
Since we already have [tex]r_{cepheid}[/tex] as 100 million light year, substitute for luminosity of supernova and luminosity of cepheid as 10⁸[tex]L_{sun}[/tex] and 10,000[tex]L_{sun}[/tex] respectively in equation (a)
[tex]r_{supernova} = 100 million \sqrt{\frac{10^8L_{sun}}{10,000L_{sun}} }[/tex] ==> 10 billion light year
the ratio of the distance to the size of the universe:
Supernova / Observable Universe = (10 / 14) billion light years
Supernova / Observable Universe = 0.7
The supernova is a fraction of the size of 0.7 of the size of the viewable universe that is 10 bn light years away.
What is supernova and how far is it. ?The supernova is a very powerful and luminous Steller explosion and is a transitional astronomical event and take place ducting the evolution and is one of the stages of the massive star. Triggered by the leakage of the gases.
The distance of the fading of a white dwarf supernova of brightness is 108 sun and has brightness as comparable to that star of the brightest Cepheid. The star has a variable of 100 million light years form earth. Thus distance of the nearest supernova is 50 billion light years and the observable is 10 billion.

Explanation:
Tropical rainforests are not located in England. The mainly regions was the Philippines, Australia, and South America. Thus, option (d) is correct.
What is Tropical rainforests?Tropical rainforests can be found in South and Central America, central and eastern Africa, western India, East Asia, New Guinea, and Australasia. The sun almost directly strikes the tropics, releasing powerful solar energy that maintains temperatures high. The tropical rainforest is a hot, damp biome with year-round rain. It is famous for its lush vegetation canopies that form three distinct layers.
Rainforests grow on every planet except Antarctica. The world's greatest rainforests border the River in South And central america and the Congolese River in Africa. Tropical forests are found in the tropics, which are located between the Tropics of Cancer and Capricorn, slightly above and below the Equator. This environment is worldwide scarce and, according to some, more imperiled than tropical rainforest.
As a result, the Tropical rainforests are not located in England. Therefore, option (d) is correct.

Describe the differences and causes of tornades and thunderstorms.
please help due today!!!!!
Answer:
A thunderstorm is a fast-rising column of air which produces heavy rain, wind, lightning, and sometimes hail. A tornado is a violently rotating column of rising air which is spawned by and is always attached to the bottom of a rotating thunderstorm. Thunderstorms last a lot longer than tornadoes.
Explanation:
A thunderstorm is a storm with strong-enough updrafts and downdrafts that strong static electricity charges develop, leading to lightning. The extremely-rapid heating of air during a thunderstorm produces thunder.
Tornadoes develop during some, but not all, thunderstorms. They are a rapidly-spinning updraft, reducing air pressure sufficiently around their base that buildings can explode due to the outside air pressure now being considerably less than the inside air pressure. They also hurl debris long distances. They are much more destructive than regular thunderstorms.
