Why did the mt. Pinatubo eruption result in global temperatures dropping two degrees?
The eruption of Pinatubo blew thousands of tons of fine ash into the upper stratosphere. The ash clouds were carried all around the world, and increased the Earth's albedo, or reflectivity, enough so that enough sunlight was reflected back into space that the Earth actually began to cool down. These eruptions have happened many times before; for example, the 1815 eruption of Mount Tambora in Indonesia caused the 1816 "Year Without A Summer", a time of widespread crop failures and famine.
How hot was the lava in mount Pinatubo?
Mt Pinatubo is a composite volcano and the lava is primarily dacitic making it explosive and highly viscous. Dacite would likely erupt at about 800 degrees Celsius.
What can happen to global temperatures for several years after a volcanic eruption?
After a volcanic eruption, particularly a large one that emits significant amounts of ash and sulfur dioxide into the atmosphere, global temperatures can temporarily decrease. This occurs because the ash and sulfur particles reflect sunlight away from the Earth, leading to a cooling effect that can last for several years. The extent and duration of this cooling depend on the eruption's magnitude and the amount of aerosols released. Notable examples include the 1991 eruption of Mount Pinatubo, which caused global temperatures to drop by about 0.5 degrees Celsius for a couple of years.
What might happen if a major volcanic eruption occurred every year?
Global temperatures might cool by several degrees
How hot is mount vesuvius?
Currently the temperature on Mount Vesuvius is no different from that of an ordinary mountain. Temperatures at certain spots may approach 2,000 degrees Fahrenheit during an eruption, but the last eruption at Mount Vesuvius was in 1944.

What thing's temperature may reach as high as 2000 degrees Celsius?
Lava during a volcanic eruption can reach temperatures of 2000 degrees Celsius.

Global temperatures might cool by several degrees
What digrees do volcaneos get up to when they irrupet?
During volcanic eruptions, temperatures can vary significantly depending on the type of eruption and the materials involved. Lava temperatures typically range from about 700 to 1,200 degrees Celsius (1,300 to 2,200 degrees Fahrenheit). In explosive eruptions, pyroclastic flows can reach temperatures of up to 1,000 degrees Celsius (1,832 degrees Fahrenheit). Additionally, volcanic gases can also be extremely hot, contributing to the overall heat during an eruption.

How hot is the basalt lava from the Kilauea volcano in Hawaii?
The basalt lava from Kilauea volcano in Hawaii can reach temperatures between 1,070 to 1,170 degrees Celsius (1,958 to 2,138 degrees Fahrenheit). These temperatures can vary depending on the specific eruption and the type of lava being produced.
In a hot and dry desert how hot does it get?
In a hot and dry desert, temperatures may occasionally reach 50 degrees Celsius, or 122 degrees Fahrenheit . The norm in summer is 30 - 35 degrees C. Even in a hot desert, winter nights can be very cold, dropping to sub-zero temperatures Celsius.
What planet has a wide range temperature on its surface?
Mercury has a wide range of surface temperatures, with daytime temperatures reaching up to 800 degrees Fahrenheit (427 degrees Celsius) and dropping to -290 degrees Fahrenheit (-180 degrees Celsius) at night due to lack of atmosphere to retain heat.
Temperatures generally encountered during volcanic eruptions are approximately what degrees?
Temperatures during volcanic eruptions can vary widely, ranging from 700 to 1,200 degrees Celsius (1,292 to 2,192 degrees Fahrenheit) for flowing lava, and even higher temperatures for pyroclastic flows and gas emissions. The exact temperature will depend on the type of volcanic eruption and the composition of the magma involved.
