A year and a half ago, my daughters and I visited Cabo San Lucas in Mexico with my brothers and parents. While walking along the beach, we noticed large rocks protruding from the shore. The rocks were beautiful, and upon examination we could tell that they were granite. These granite rocks must have formed underground considering the crystals in them. This type of igneous rock is considered intrusive as it forms underground. Since it forms under the ground, it cools very slowly allowing time for a lot crystals to form. This created the beautiful granite we saw on our lovely walks along the beach. The granite is now above the Earth’s surface due to shifting tectonic plates. This process took about 25 million years.
