6. Challenge: Based on the weathering patterns, guess the rock type shown in each photo. (Can anyone confirm or deny these answers?)

Weathering is the process of removal and breaking down of the rocks into soils and minerals and is four types such as physical, chemical, and biological. The weather is both an internal and external process.

Learn more about the weathering patterns, guess the rock type.

A. = Shale

B = Granite

C = Sandstone

D = Limestone

Explanation:

Based on the weathering patterns, the rock type shown in each photo can be concluded to be as

A. = Shale: this is a form.of sedimentary rocks. It is formed from finely textured materials. Such as clay, quartz, and calcite minerals

B = Granite: this is derived from igneous rock. It has coarse texture features.

C = Sandstone: it is formed by a sand-sized grain of natural earth materials that form together

D = Limestone: it is also a form of sedimentary rock. It contains a large quantity of calcium carbonate it is formed from materials such as ancient corals and skeleton.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
