Basically two ways. Intrusive igneous rock is formed when magma cools and solidifies beneath the surface of the earth. These rocks are also called plutonic rocks.
Hurricane Irma is the strongest Atlantic basin hurricane ever recorded outside the Gulf of Mexico and the Caribbean Sea. It lasted as a hurricane from August 31 until September 11. The storm, which stretched 650 miles from east to west, affected at least nine US states, turning streets into rivers, ripping down power lines, uprooting trees and cutting off coastal communities.
While the US territory of Puerto Rico received a glancing blow from Irma (an event that primarily affected Culebra, Vieques and its northeast coast), the entire island was devastated just a week later by Hurricane Maria as the storm etched a diagonal path from the southeast to the northwest corner.
