Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The igneous rock gabbro most likely formedfrom molten material that cooled(1) rapidly at Earth’s surface(2) slowly at Earth’s surface(3) rapidly, deep underground(4) slowly, deep underground

A	rapidly at Earth’s surface
B	slowly at Earth’s surface
C	rapidly, deep underground
D	slowly, deep underground

Explanation:

Detailed explanation-1: -Gabbro makes the majority of the Earth’s oceanic crust beneath the surface. an ultramafic, coarse-grained igneous rock that forms from magma and is primarily composed of olivine and pyroxene.

Detailed explanation-2: -Gabbro is a coarse-grained igneous rock that forms when iron-rich magma cools slowly deep within the Earth.

Detailed explanation-3: -Extrusive igneous rocks form when lava reaches the Earth’s surface a volcano and cools quickly. Most extrusive (volcanic) rocks have small crystals. Examples include basalt, rhyolite, andesite, and obsidian.

Detailed explanation-4: -Extrusive Igneous Rocks: Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth’s surface. These are the rocks that form at erupting volcanoes and oozing fissures.
