Petrology: The Science of Rocks

Petrology field study and laboratory analysis showing geologist examining rocks in the field and petrographic microscope with rock samples in a laboratory environment

Introduction Petrology is a fascinating branch of geology that focuses on the study of rocks—their composition, origin, and history. While most people see rocks as simple stones scattered on the ground, each rock contains a story of Earth’s formation and…

What Is a Rock? Definition and Types

Feature image showing the rock cycle with igneous, sedimentary, and metamorphic rocks forming a continuous cycle.

Rocks are one of the most fundamental components of the Earth. From the mountains we see on the horizon to the stones beneath our feet, rocks shape the planet’s surface and preserve its long geological history. Understanding what a rock…

What is Mineralogy and Its Main Branches

Illustration showing minerals, their types, and the main branches of mineralogy including physical, chemical, and descriptive mineralogy.

The Earth is made up of minerals, which act as its fundamental building blocks.They are naturally occurring, solid substances with a definite chemical composition and a specific atomic structure. Every rock, soil, and even the metals we use in daily…

Structural Geology: Definition & Importance

Why Structural Geology Is Important in Engineering, Environment, and Resource Exploration

What is Structural Geology? Structural Geology is the study of rock structures, their deformation, and three-dimensional arrangement in the Earth’s crust. It explores how rocks fold, fracture, and layer over time due to forces such as stress, pressure, and tectonic movements. Understanding…

Rock Cycle with Iron: Simple Science Guid

Diagram of the rock cycle showing igneous, sedimentary, and metamorphic rock transformations

Introduction The rock cycle is a natural process where rocks change form over millions of years; iron can be used as an example to illustrate these changes. Note: The iron example is used only for understanding. Rocks and iron are different…
