What is a Sediment Core?
Practice Version
Sediment Core:
A section of a naturally-occurring substance, such as sediment or rock. Sediment core. A sediment core is a cylindrical sample taken from the ground to study layers of soil, rock, or ice and learn about Earth's history.
Example:
Imagine trying to remember what you had for lunch every day over the past month. Just as your memory holds clues to your recent meals, a sediment core holds clues to Earth's past environments. Each layer of the sediment core is like a day in your memory, capturing a snapshot of conditions at that time, allowing scientists to 'read' the history of the Earth much like you might recall your meals by thinking back to those specific days.
