What rock has more silica Extrusive or intrusive?
Intrusive rocks typically have more silica than extrusive rocks. This is because intrusive rocks form when magma cools slowly beneath the Earth's surface, allowing more time for minerals rich in silica to crystallize. In contrast, extrusive rocks form when lava cools quickly on the Earth's surface, resulting in a rock with less time for silica-rich minerals to develop.

False there classified as basaltic, andesitic and rhyolitic based on amount of silica.
