How high must one ascend to observe the curvature of the Earth?
To observe the curvature of the Earth, one must ascend to a height of at least 35,000 feet, which is roughly the cruising altitude of commercial airplanes.
How do volcanic particles get into the atmosphere?
During a volcanic eruption, hot magma and gas propel rock fragments and ash into the air. These particles can reach high altitudes due to the explosive force of the eruption. Ash clouds can also be carried by wind over long distances.
About how many people did the 1669 eruption kill?
The 1669 eruption of Mount Etna killed 20,000 people. The death rate was so high because citizens refused to leave their city before the eruption occurred.
Volcanic eruption types is the most violent?
Pelean
How did Eyjafjallajokull eruption happen?
The Eyjafjallajökull eruption in 2010 was triggered by magma interacting with water under the glacier, leading to explosions that ejected ash and steam high into the atmosphere. The eruption resulted in a large ash cloud that disrupted air travel across Europe due to the potential damage ash could cause to aircraft engines.
What is the disadvantage of venturi flume?
Disadvantages of Venturi Flume: ➨It has nonlinear flow characteristics. ➨When velocity decreases, deposit gets build up and headwater gets obstructed. ➨There is a risk of plugging due to large floating items through it. ➨Measurement is not possible when backflow exists in tail water upto the venturi flume. ➨Quality and reliability of the measurement depend on sensors used in venturi flume. ➨Installation cost is high. ➨It affects local fauna.
What are three types of environmental factors that might affect organisms?
loud noisy. high flume tv/radio
What is an eruption cloud?
An eruption cloud is a large plume of volcanic ash, gases, and other material that is ejected into the atmosphere during a volcanic eruption. These clouds can reach high into the atmosphere and pose hazards to aviation, health, and the environment.
How high ash goes from a volcanic eruption?
to high for me to jump
When Mount Vesuvius last erupted did the lava have high or low viscosity?
The lava from Mount Vesuvius during its last eruption in 1944 had high viscosity, meaning it was thick and flowed slowly. This type of lava often leads to explosive eruptions and can create steep-sided volcanoes.
What thing's temperature may reach as high as 2000 degrees Celsius?
Lava during a volcanic eruption can reach temperatures of 2000 degrees Celsius.
How dangerous is it when lava rocks explode during a volcanic eruption?
When lava rocks explode during a volcanic eruption, it can be very dangerous. The exploding rocks can travel at high speeds and cause injuries or damage to property. It is important to stay a safe distance away from volcanic activity to avoid getting hurt.
How high must one ascend to observe the curvature of the Earth?
To observe the curvature of the Earth, one must ascend to a height of at least 35,000 feet, which is roughly the cruising altitude of commercial airplanes.
An explosive eruption occurs if magma is?
An explosive eruption occurs if magma is high in gas content and viscosity. The high gas content creates pressure within the magma chamber, leading to a violent release of energy when the eruption occurs. The high viscosity of the magma makes it more difficult for gases to escape, further increasing the explosiveness of the eruption.
What is the type of volcanic eruption that has high silica?
Crazy
What is the average height of an eruption?
about 34m to 98m high
What makes a quiet eruption different from an explosive eruption?
quiet eruption flows easeir cause it has a low viscosity and lava flows easier but explosive eruption has a high viscosity and lava flows slower
