What is a protolith in geology?
In geology, a protolith refers to the original rock from which a metamorphic rock is formed. It represents the parent rock that undergoes changes in mineralogy, texture, and structure during the process of metamorphism. The protolith can be any type of rock, such as sedimentary, igneous, or anotherRead more
In geology, a protolith refers to the original rock from which a metamorphic rock is formed. It represents the parent rock that undergoes changes in mineralogy, texture, and structure during the process of metamorphism. The protolith can be any type of rock, such as sedimentary, igneous, or another metamorphic rock, and the specific characteristics of the protolith influence the resulting metamorphic rock.
See lessHow fast do tectonic plates move relative to each other (in km/year)?
The movement of tectonic plates is relatively slow, occurring over millions of years. The average rate of movement is estimated to be around 2-15 centimeters per year (cm/year) or approximately 20-150 kilometers per million years (km/Ma). However, the rate of movement can vary depending on the locatRead more
The movement of tectonic plates is relatively slow, occurring over millions of years. The average rate of movement is estimated to be around 2-15 centimeters per year (cm/year) or approximately 20-150 kilometers per million years (km/Ma). However, the rate of movement can vary depending on the location and type of plate boundary. For example, the rate of movement along the mid-Atlantic Ridge is around 2.5 cm/year, while the rate of movement along the San Andreas Fault in California is around 5 cm/year.

its broadest sense, geology is the study of Earth — its interior and its exterior surface, the rocks and other materials that are around us, the processes that have resulted in the formation of those materials, the water that flows over the surface and lies underground, the changes that have taken place over the vastness of geological time, and the changes that we can anticipate will take place in the near future. Geology is a science, meaning that we use deductive reasoning and scientific methods (see Box 1.1) to understand geological problems. It is, arguably, the most integrated of all of the sciences because it involves the understanding and application of all of the other sciences: physics, chemistry, biology, mathematics, astronomy, and others. But unlike most of the other sciences, geology has an extra dimension, that of time — deep time — billions of years of it. Geologists study the evidence that they see around them, but in most cases, they are observing the results of processes that happened thousands, millions, and even billions of years in the past. Those were processes that took place at incredibly slow rates — millimetres per year to centimetres per year — but because of the amount of time available, they produced massive results.
Geology is displayed on a grand scale in mountainous regions, perhaps nowhere better than the Rocky Mountains in Canada (Figure 1.1). The peak on the right is Rearguard Mountain, which is a few kilometres northeast of Mount Robson, the tallest peak in the Canadian Rockies (3,954 m). The large glacier in the middle of the photo is the Robson Glacier. The river flowing from Robson Glacier drains into Berg Lake in the bottom right. There are many geological features portrayed here. The sedimentary rock that these mountains are made of formed in ocean water over 500 million years ago. A few hundred million years later, these beds were pushed east for tens to hundreds of kilometres by tectonic plate convergence and also pushed up to thousands of metres above sea level. Over the past two million years this area — like most of the rest of Canada — has been repeatedly glaciated, and the erosional effects of those glaciations are obvious. The Robson Glacier is now only a small remnant of its size during the Little Ice Age of the 15th to 18th centuries, as shown by the distinctive line on the slope on the left. Like almost all other glaciers in the world, it is now receding even more rapidly because of human-caused climate change.

Geology is also about understanding the evolution of life on Earth; about discovering resources such as metals and energy; about recognizing and minimizing the environmental implications of our use of those resources; and about learning how to mitigate the hazards related to earthquakes, volcanic eruptions, and slope failures. All of these aspects of geology, and many more, are covered in this textbook.

Geology is the study of the earth (geo means earth, and ology means study of). This is a very simple definition for something so complex. Geology involves studying the materials that make up the earth, the features and structures found on Earth as well as the processes that act upon them. Geology also deals with the study of the history of all life that’s ever lived on or is living on the earth now. Studying how life and our planet have changed over time is an important part of geology.
