“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 ...

Weathering and erosion slowly chisel ... Critters big and small trample, crush, and plow rocks as they scurry across the surface and burrow underground. Plants and animals also produce acids ...

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

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.

Erosion is the suspected culprit in Thursday's collapse of the arch -- a hole formed in the 190-million-year-old sandstone rock situated along Lake Powell, the National Parks Service announced.
