Darwin explained that evolution occur due to natural selection.
Answer:
igneous
Explanation:
Igneous rock is the type of rock that contains a large amount of silica. Igneous rocks are formed when molten rock (magma or lava) cools and solidifies. Silica is a common component of magma, so igneous rocks are often rich in silica. Glass, which is also made from silica, is not a type of rock. Metamorphic and sedimentary rocks are formed through processes that do not involve the melting of rock, so they typically contain lower amounts of silica.
