Volcanic eruptions expel molten magma, ash, and gases collectively known as:
Show answer Hide answer
Answer: A. Solid, liquid, gaseous
Explanation
Volcanic eruptions forcefully expel a complex mixture of solid rock fragments, liquid lava, and gases. Solid tephra, molten lava, and volatile gases represent all three states of physical matter. This diverse mixture emerges from subterranean magma chambers under intense pressure. Magma contains dissolved gases that expand explosively as pressure decreases during ascent. Volcanic emissions include ash, pumice, molten rock, steam, and carbon dioxide. States of matter include solids, liquids, and gases interacting dynamically during eruptions.
Volcanic ash and gases can impact global climate by blocking sunlight and altering weather. Studying eruption products helps volcanologists assess hazards and protect nearby human populations. Magma outgassing has played a crucial role in forming Earth's early atmosphere and oceans. Listing only solid and liquid misses the massive volume of volcanic gases released. Omitting liquid lava ignores molten flows that frequently accompany explosive eruptions. Selecting none of these is wrong because eruptions clearly eject all three states of matter.
