You find an extrusive igneous rock. it was formed from lava cooling on earth's surface has large crystals from cooling very slowly is made of rock fragments, bone, and sediment was formed from heat and pressur

The correct answer to this item is "was formed from lava cooling on earth's surface." 

By definition, an extrusive igneous rock was formed as soon as the magma reached the Earth's surface from a certain volcano activity and it cools rapidly. The rock that was formed is considered an extrusive igneous rock.

formed from lava cooling on earth's surface

Explanation:

An extensive igneous rock is formed by the hot magmas inside the earth and then flows out to the surface as violent lavas and explodes in the air to fall back. In contrast to the intrusive rock that refers to the rock, that is formed by the magma that cools below the surface. As this magma can cool much easily and quickly t the room temperatures and thus there is little time for the growth of crystals. and contains abundant volatile matter when the gas is released.   An example of this is the shield volcanoes that are large and slow forming and tends to erupt with the extrusive basaltic rock.

Idk bro sorry  lava is hotter then magma but im  not sure about it alll
