Exploring Sedimentary Rocks in Planet Earth Lab 3

The video tutorial covers the formation and classification of sedimentary rocks, focusing on clastic and precipitant types. It explains the processes of weathering, erosion, transportation, deposition, and lithification. Clastic rocks are classified by grain size, while precipitant rocks include carbonates like limestone and dolomite. The video also discusses other sedimentary rocks such as evaporites, coal, and chert, and their environments of deposition. A lab activity is introduced to reinforce the concepts learned.

• Lithification

• Deposition

• Weathering

• Erosion
