Common Minnesota Rocks. Throughout geologic time, Minnesota's landscape has undergone many changes. At times, high mountains lined the horizon. Later, vast seas engulfed the region. Still later, great sheets of ice covered the land. All of these environments are recorded in the rocks and sediments found around the state.

Chalk is a sedimentary rock primarily composed of calcium carbonate (calcite). It is formed from the accumulation of microscopic marine organisms’ remains, especially coccolithophores. Chalk is known for its distinctive white color, fine-grained texture, and softness. It is commonly associated with marine environments.7 Sedimentary Rock Identification Match the Name to the Rock: Example 1. Drag the rock name to the correct rock.
