Foremost of these are magma viscosity, gas loss and external properties such as conduit geometry. Ultimately, these parameters control the speed at which magmas ascend, decompress and outgas en route to the surface, and thus determine eruptive style and evolution.
Nothing time only changes when you move east or west.
Answer:
deserts, grasslands, mountains, and tropical areas. its a very large area that covers a lot of asia.
Answer:
Viscosity directly affect the speed of convictions.
Explanation:
The speed of convection in Earth’s mantle, oceans, and atmosphere also depends on the viscosity of the fluids. If the viscosity of fluids is higher so it takes more time to complete the process of convection in Earth’s mantle, oceans, and atmosphere, while on the other hand, if there is lower viscosity of fluids, the conviction in the mantle, oceans, and atmosphere of earth occur in high speed due to easily movement from place to place.
The first notable volcanic activity since 1992-93, when there was dome growth and secondary phreatic explosions in the aftermath of the major 1991 eruption, is a phreatic explosion from the summit crater lake at Pinatubo in November 2021.
<h3>What evidence exists to suggest that the 1991 eruption of Mount Pinatubo rendered lahar unsafe?</h3>
Lahars at Pinatubo since 1991 In the years that followed the devastating eruption in 1991, they deposited more than 0.7 cubic miles (3 cubic kilometers; hundreds of square miles of land were submerged by the debris, which was the equivalent of 300 million dump truck loads, in the lowlands surrounding the volcano.
<h3>How were they aware of the impending eruption of Mount Pinatubo?</h3>
Seismic data and an increase in sulfur dioxide released from the volcano by May 1991 suggested to scientists that the volcano's magma chambers were being filled with new magma. The rapidly expanding lava dome on Pinatubo hinted at a forthcoming large-scale eruption.
