Question

geologists consider the possibility of a volcanic eruption stronger than any that have occurred in recorded history. what effect could such an eruption have on other systems on earth? a the volcanic blast would induce powerful earthquakes throughout the world. cities would be devastated, and tremors would continue at dangerous levels for several years. b tectonic plates near the eruption would experience a jolt strong enough to significantly increase their rate of movement. huge ocean waves would form and wipe out ecosystems. c harmful levels of uranium dust would spew from the volcano and spread globally through the atmosphere. radioactive precipitation would lead to significant numbers of plant and animal mutations. d ash and gases from the volcano would move globally through the atmosphere, blocking sunlight and lowering temperatures. the increase in snowfall would further reflect sunlight and cool temperatures.

Explanation:

Volcanic eruptions release large - amounts of ash and gases. These can disperse globally in the atmosphere. Ash blocks sunlight, reducing the amount of solar radiation reaching the Earth's surface, which lowers temperatures. Increased snowfall due to cooling further reflects sunlight, enhancing the cooling effect. Option A over - states the earthquake impact as a single eruption won't cause world - wide earthquakes for years. Option B exaggerates the plate movement and tsunami impact from a single eruption. Option C is incorrect as uranium is not a typical volcanic emission.

D
