Secrets Beneath Your Feet—The Fascinating World of Scientific Drilling

Abstract

Why do scientists drill into the Earth? Drilling is a valuable tool to unravel secrets of the planet’s history because lots of information is safely stored deep below our feet within the Earth. By taking samples from deep in the Earth and performing laboratory tests on them, scientists find rock materials, water, bacteria, and fossils that can help to unravel mysteries of life and the environment over millions of years. Drilling is also important for finding sustainable new resources, such as geothermal heat, which can be used to produce energy for our homes. Drilling can also help us understand and protect our planet. Another important reason for drilling is to install specific instruments deep in the Earth, to monitor Earth’s movements. These instruments help us to better understand natural disasters like earthquakes or volcanic eruptions and can enhance the safety of billions of people worldwide.
