which of the following is formed from molten rock that contains large amounts of gasses??
A: Rhyolite B: granite
C:basalt D: pumice
Ever wonder why pumice is so light it floats?
because it has a lot of gas in it??
You win the prize.
To determine which of the following options is formed from molten rock that contains large amounts of gases, we'll need to examine the characteristics of each rock type.
A: Rhyolite - Rhyolite is an igneous rock that forms from volcanic activity. However, it typically contains a lower proportion of gases compared to other options.
B: Granite - Granite is an igneous rock that forms from the slow cooling of magma underground. It does not typically contain high amounts of gases.
C: Basalt - Basalt is an igneous rock that forms from the rapid cooling of lava on the Earth's surface. It can contain varying amounts of gases, but not necessarily large amounts.
D: Pumice - Pumice is a volcanic rock that is formed from the rapid cooling and depressurization of frothy magma. It contains numerous gas bubbles and is known for its lightweight and porous nature. Therefore, pumice is the correct answer option.
So, the answer is D: Pumice.
