But in some places, people must carry gallons of water from the closest stream, river, lake, or well to their homes.
Investigating Different Rock Types
Investigating Rock Types
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.
