Taking a strike and dip in the field but it’s paced like One Piece... ☠️
Geologists use compasses to measure the orientation of rock layers in the field! 🪨 A good way to think of it is with the right hand rule. Take your right hand and orient it so that your fingers point “down-dip,” or on the slope of the plane. Your thumb will be the direction you measure strike, and your fingers will be the dip! 🧭 Similar methods can be used for other features, like fault orientations, lineations, etc. 😎
Understanding the architecture of the rocks beneath our feet is important for making structurally sound infrastructure, avoiding groundwater contamination, assessing geologic hazards like earthquakes and landslides, evaluating economic resources like minerals and hydrocarbons, and more! The list of geology’s uses goes on and on 🌎⛏️
