According to this selection, which event leading to an eruption happens first?

A
The bubbling mantle behaves like a liquid entering fissures inside a volcano.

B
The magma becomes syrupy during its slow movement.

C
The ocean crust releases heated water that seeps into the mantle.

D
The thick magma plugs up the volcano's fissures.

Respuesta :

I think the answer would be c

The correct option is D. The volcano's cracks are plugged by the heavy magma.

What is a volcano?

  • A volcano is an opening or rupture in the surface of the earth through which gases, volcanic ash, and hot liquid or semi-liquid rock can escape.

What happens in a volcanic eruption?

  • Volcanoes often develop when tectonic plates collide or diverge, but volcanic hotspots can also cause them to form in the midst of plates.
  • When lava and gas are released from a volcano, often explosively, this is known as an eruption.
  • A "glowing avalanche," which occurs when recently erupted lava slides down the flanks of a volcano, is the most hazardous type of eruption.
  • They are capable of swift movement and can reach temperatures of 1,200 degrees Fahrenheit. Other dangers include lahars and ash fall (mud or debris flows).
  • Food shortages and population dislocation are frequent effects of volcanoes.

The first step that leads to an eruption is that the thick magma blocks the volcano's fissures.
