Identify the series of geologic processes that can transform magma into granite, granite into sand, and sand into sandstone

Answer:
The series of geologic processes involved in transforming materials from one form to another are crucial in understanding the rock cycle. Here are the processes that can transform magma into granite, granite into sand, and sand into sandstone:

  1. From Magma to Granite (Igneous to Igneous Rock):

    • Solidification: The first step is the cooling and solidification of magma. As magma cools underground, it solidifies and crystallizes to form igneous rock, which in this case is granite.

  2. From Granite to Sand (Igneous to Sedimentary Rock):

    • Weathering: Granite is subjected to weathering processes such as physical and chemical weathering. This can include processes like frost wedging, root wedging, and hydrolysis, gradually breaking down the granite into smaller particles.
    • Erosion and Transport: Once the granite is weathered, the weathered particles are eroded by agents like water, wind, or ice. These particles are transported away from their origin to new locations.
    • Deposition: The eroded granite particles are deposited in sedimentary basins by the transporting agents. Over time, these deposits accumulate and undergo compaction and cementation to form sedimentary rocks such as sandstone.

  3. From Sand to Sandstone (Sedimentary to Sedimentary Rock):

    • Lithification: The process begins with the deposition of sand particles, which accumulate in layers. Over time, as more sediment is deposited above, the lower layers experience compaction due to the weight of overlying sediments.
    • Cementation: As the sediments are compacted, minerals precipitate from groundwater and fill the spaces between the grains, binding them together. This process is known as cementation and results in the formation of sandstone.

Understanding these processes helps geologists decipher the history recorded in rocks and provides insights into the dynamic Earth processes that continuously shape and reshape the planet’s surface.
