These include weathering, erosion, transportation and sedimentation ... Weathering close weatheringWeathering breaks down rocks on the surface of the Earth into smaller pieces.

“Harder rocks should equal slower erosion rates.” To test their hypothesis, the researchers measured erosion rates by analyzing river sediment and the amount of beryllium-10, a radioactive isotope ...

Weather also has an impact on the coastline. Rainwater can cause surface erosion and frost (in cold climates) can cause rock to shatter. Strong winds can also contribute to the erosion of cliffs.

"These gaps are the physical manifestation of past erosion events that removed ... revealing when these rocks were pushed to the near-surface of the Earth," Jensen says. "Using (U-Th)/He and ...
