What is a volcanic twilight?
A volcanic twilight is a light phenomenon that can occur in the weeks and months following a major volcanic eruption. The ash and aerosols produced by the eruption interact with the sunlight, producing especially colorful and brilliant sunsets and twilights.
What are five examples of pyroclastic debris?
Five examples of pyroclastic debris include ash, pumice, volcanic bombs, volcanic blocks, and tephra. Ash consists of fine particles that can be carried by wind over long distances, while pumice is a light, frothy rock that can float on water. Volcanic bombs are larger, solid fragments ejected during an eruption, and volcanic blocks are hardened lava pieces. Tephra encompasses all types of volcanic debris ejected into the air during eruptions.
How does a volcanic eruption effect photosynthesis?
A volcanic eruption puts ash into the air, which cuts off sunlight to the plant. Light is needed for photosynthesis to happen, so photosynthesis wouldn't happen if a volcano erupted near the plant.
Why are sunsets red after a volcanic eruption?
When light from the sun passes through a greater thickness of the atmosphere more light from short wavelengths of visible light (blue and violet) is removed by scattering before it reaches your eyes leaving behind long wavelengths of visible light (red and orange) that also reflect off of clouds making them red too, that's what makes sunsets and sunrises red too because when the sun is setting or rising it's light has to pass through more gases in the atmosphere instead of in the afternoon when its high in the sky (blue sky). When volcanic ash is the air it thickens the atmosphere and can be reflected off of the particles.
What makes volcanic rocks light and porous?
Volcanic rocks can become light and porous when they contain a high percentage of gas bubbles, mostly water vapor and carbon dioxide, trapped during the volcanic eruption. As the lava cools rapidly and solidifies, these gas bubbles remain within the rock, creating pores and reducing the overall density of the rock. Additionally, the rapid cooling process can prevent the formation of large mineral crystals, contributing to the porous nature of volcanic rocks.
What are two factors that can affect the distance that volcanic ash can travel?
Wind direction and speed: Strong winds can carry volcanic ash over long distances, while variable wind patterns can influence the direction in which the ash travels. Eruption intensity: The height and explosiveness of the volcanic eruption can determine how high into the atmosphere the ash plume reaches, affecting how far it can be dispersed.
Why might a major volcanic eruption lead to cooler temperature over a lrge area around the volcano?
when a large volcanic eruption happens, it'll most likeyl send up a large gas cloud into the air that blocks out the sun for a while. the blockage of the suns heat cools down the surrounding area until the cloud dissipates
How do volcanoes cause sunsets?
As far as I know, there is no connection between volcanoes and sunsets. After an eruption, all the ash etcetera released could possibly darken the sky and give the impression of dusk, though it would have nothing to do with the position of the sun.
Why does volcanic ash looks like snow?
It depends on the kind of eruption. In a Hawaiian type eruption parts of the volcano are covered in red hot lava flows and there may be a fountain spewing lava hundreds of feet into the air. In a Strombolian eruption explosions create a firework-like display of airborne lava, which may form lava flows. Some ash may rise from the fountain of lava. In a Vulcanian eruption the volcano produces clouds of ash and sends blocks of rock and globs of lava out at high speeds. In a Pelean eruption the volcano is covered in large clouds of ash. In a Plinian eruption the volcano sends a vertical column of ash miles into the sky to spread out at high altitude. The volcano itself may be covered in clouds of ash.
What is polymorphous light eruption?
2 weeks
How many people died in the eruption of Eyjafjallajokull in 2010 Iceland?
150,000 people are stranded because of the volcanic ash
What are the pulverized rock and lava and other fragments ejected from the vent of the volcano called?
Tephra.. (not pumice - Pumice is the light stone which forms during an eruption)
