Sandstone can be transformed into quartzite through the process of metamorphism, which involves high temperatures and pressures that recrystallize the grains in the sandstone, causing them to fuse together and form a harder, more compact rock. This process also typically involves the migration of silica within the rock, leading to the growth of larger quartz crystals and the loss of original sedimentary features.

A major difference between Catastrophism and Uniformitarianism is?
that Catastrophism proposes that Earth's geological features were mainly formed by sudden, short-lived events such as floods or volcanic eruptions, while Uniformitarianism suggests that these features were shaped over long periods of time by gradual, continuous processes like erosion and sedimentation.
What is the series of processes in which a rock forms changes from one type to another is destroyed and forms again by geological processes?
The series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes is known as the rock cycle. It involves processes such as weathering, erosion, deposition, heat, and pressure that continuously transform rocks from one type to another over geologic time scales.
The series of changes that describes how geologic forces cause rock to change from one type to another is known as?
The series of changes that describe how geologic forces cause rock to change from one type to another is known as the rock cycle. It involves processes such as weathering, erosion, deposition, compaction, and metamorphism that transform rocks over time.
When does geologic processes occur?
Geologic processes occur constantly over long periods of time, shaping the Earth's surface and internal structure. These processes include plate tectonics, erosion, volcanic activity, and mountain building, among others. The combination of these processes work together to create and modify the features of the Earth we see today.
What geologic theory can be summarized by the phrase the present is the key to the past''?
The principle of uniformitarianism states that the same geologic processes that operate today have been occurring throughout Earth's history. This suggests that by studying modern geologic processes, we can gain insights into how similar processes shaped the Earth in the past.
