Faye Moser MS Candidate in Earth Science University of North Carolina Charlotte fviscounccedu September 2016 GSA Dr Martha Cary Eppes Univ of N Carolina Charlotte Dr Brian Collins . Chapter 5.1. What is Weathering?. Weathering can be defined as any. chemical or mechanical process by which rocks exposed to weather undergo changes in character or are broken down into smaller pieces. and Ice Conditions In and Near the Marginal Ice Zone: . The "Marginal Ice Zone Observations and Processes EXperiment" (. MIZOPEX. ). . Goals. : .  . Assess ocean and sea ice variability during the melt season within a key Marginal Ice Zone (MIZ) region. .

Also called…. . “Ice Wedging”. Weathering. The breaking down of rock into smaller pieces that remain next to each other. . Weathering forms sediments.. There are two types of weathering.. Mechanical (Physical) . Chemical. Mechanical Weathering. Erosion. The carrying weathered rock from one location to another . Mechanical Weathering. Rock is physically broken down. Smaller pieces have same composition. Chemical Weathering. Rock is chemically broken down. Predict how weathering might reshape surface features (topography). Weathering and Erosion. The top part of the lithosphere—the earth’s surface—changes as rocks are broken down to smaller pieces and carried away.. Weathering can be defined as any. chemical or mechanical process by which rocks exposed to weather undergo changes in character or are broken down into smaller pieces. .. Mechanical Weathering.
