lava is question 6 options: a) always produced during any volcanic activity. b) molten rock that cools and hardens on earth's surface. c) all the same chemical composition, whether it is rhyolite or basalt. d) the most life-threatening volcanic product of any eruption.

Respuesta :

All the statements given are true about lava.

Molten rock that comes from an erupting volcano is called lava. It is very hot, with peaks between 1,300 and 2,000 degrees Fahrenheit (704 to 1093 degrees Celsius). Lava is liquid when it erupts during a volcanic explosion. Igneous rock is what it becomes after solidifying. However, it may take a while for it to cool and travel a long way before solidifying.

Magma contains gas bubbles underground. The pressure exerted by the layers of underlying rocks typically prevents these gas bubbles from expanding. However, occasionally the gas pressure might grow to a point where the bubbles start to expand and rise, carrying magma with them. When the pressure builds up to an extreme level, the volcano may crack, allowing magma to escape, allowing the bubbles to rapidly expand, and resulting in a lava eruption.
