Geology is divided into several fields that can be grouped under the main headings of physical and historical geology. Applied Geology Applied Geology is geologic knowledge to solving geologic problem. In other words, application of various fields of geology to economic, engineering, water-supply, or environmental problems; geology related to the human activity. METHODS OF GEOLOGY Geologists use primary data associated with petrology (the study of rocks), stratigraphy (the observe of sedimentary layers), and structural geology (the have a look at of positions of rock devices and their deformation). In many cases, geologists additionally take a look at contemporary soils, rivers, landscapes, and glaciers; inspect past and contemporary life and biogeochemical pathways, and use geophysical techniques to investigate the subsurface.

10 Dangerous Volcanoes on Earth

Why Some Volcanoes Are Far More Dangerous Than OthersWhen people imagine a volcano, they usually picture slow-moving red lava gently flowing down a mountainside....

Metamorphic Textures & Fabrics

When a rock enters the metamorphic environment, it begins a slow but profound transformation. Heat increases, pressure rises, minerals dissolve and re-crystallize, grains rotate,...

Textures of Igneous Rocks

When geologists study igneous rocks, the first thing they look at is not color or composition, but texture — the size, arrangement, and relationship...

I’ve spent a good part of my life walking around volcanic fields, climbing old lava flows that look like frozen waves, and tapping on...

Index Minerals and Metamorphic Grades

What Are Index Minerals?Metamorphic rocks record the physical and chemical changes that occur deep within Earth’s crust. Among the most important clues to these...

Erosion and Weathering: Examples & Processes

The surface of our planet is constantly changing. Mountains crumble, valleys deepen, and rocks break apart over time. These transformations occur because of two...

Basalt vs Granite – Key Differences

Basalt and granite are among the most common and important igneous rocks on Earth. Both form from molten magma, but under very different conditions.Basalt...
