In any science, it is important to accurately and understandably describe your observations for others. Whether for advancing research or informing the public, communicating your work is critical.
For geologists, this comes down to describing rocks’ colors, patterns, shapes and other features. These features may reveal evidence about the past, clues to their suitability for a construction project, or signs of valuable natural resources hidden within them.
People find inspiration in many different places and things. Among them is taking joy in sensing the Earth around you. Feel the breeze on your face. Take in the fresh smell of the air after a spring rain. Use your hands to build something. Wherever you live you can get outside, savor your surroundings and observe what makes up the rhythms of the place you live.
You may have seen or used Global Positioning System (GPS) devices in cars or on camping trips. These devices use data from satellites orbiting the Earth to locate places on our planet. GPS devices describe the locations to us in the form of latitude and longitude coordinates.
When it comes to slipping, sliding, and stability in soils, the key word is “liquefaction.”
During an event like an earthquake, liquefaction is the process by which saturated soil behaves like a liquid. This can be problematic, as a liquid soil loses structure and can cause buildings to sink, foundations to crack, and soil to slide down slopes all at once.
How does the type of soil affect how much a house will sink or shift during an earthquake? Conduct an experiment to test your ideas!
