WebRock that forms from lava extruded onto Earth’s surface is an extrusive igneous rock. Magma that escapes Earth’s interior will lose some of its dissolved gas. If the lava hardens around gas bubbles while these gases are escaping, a small hole or vesicle will form in the rock (Figure 3.7). Web6 de mai. de 2024 · Igneous rocks form from cooling magma. Magma that erupts onto Earth’s surface is lava, as seen in figure 4. The chemical composition of the magma and the rate at which it cools determine what rock forms as the minerals cool and crystallize. Figure 4. This flowing lava is molten rock that will harden into an igneous rock. Sedimentary …
