The sedimentary rock in question is sandstone.
Sandstone is a clastic sedimentary rock made up mostly of weathering sand size debris that accumulates where the waters are slower.
Sandstone is formed by all of the processes named above.
-weathering of the rocks
-erosion caused by water and wind
-transportation by water bodies
-deposition by the water masses where they are slower
-lithification under the pressure
-compactation while mixing with multiple other sediments.
Answer: Some geographic areas have obvious natural advantages that result in cluster formation. For example, proximity to a large port will attract exporting firms or areas rich in minerals will attract clusters of mining firms. In addition, there are three well-established reasons why firms choose locate in close proximity. The cost of transporting goods is reduced when firms are located close to their customers or suppliers. Input suppliers can exploit economies of scale in large clusters of downstream firms who, in turn, benefit from timely delivery and lower inventory costs.
Explanation: There are various types of clustering are that include:
^ Connectivity-based Clustering (Hierarchical clustering)
^ Centroids-based Clustering (Partitioning methods)
^ Distribution-based Clustering.
^ Density-based Clustering (Model-based methods)
^ Fuzzy Clustering.
^ Constraint-based (Supervised Clustering)
