Chronostratigraphy: Fundamental Concepts and Applications
Chronostratigraphy is the branch of stratigraphy that deals with the temporal relationships between rock layers. A chronostratigraphic unit refers to a block of rock that formed during a particular geological time (Salvador, 1994). Chronostratigraphy (and Geological...
Biostratigraphy: Principles, Units, and Applications in Stratigraphy
Biostratigraphy is the characterization and correlation of rock units based on their fossil content. It is based on the principle that organisms have undergone successive changes throughout geologic time. Biostratigraphic Units: Rock strata form a biostratigraphic...
Lithostratigraphy and Its Applications
Lithostratigraphy – deals with the lithology or physical properties of strata and their organization into units based on their lithological character. Lithostratigraphy Philosophy and Concept: Perhaps the most fundamental type of stratigraphic study is recognition,...
How Are Minerals Formed? The Role of Nature and Chemistry
The science of mineralogy is a branch of the earth sciences that studies minerals and their physical and chemical properties. Within mineralogy, some study how minerals are formed, where they are geographically located, and their potential uses. Mineral: A mineral is...
What is Paleontology? Branches, Fossil Formation, and Tools.
Paleontology is the scientific study of fossils, more broadly, the study of prehistoric organisms. In fact, professional conferences and publications often fall into these categories. This post gives an idea of what paleontology is and why it is essential to...
What is Gravity and Force? Explained Simply
Gravity and force are two powerful forces that shape the world as we know it. From holding us to the ground to keeping planets in orbit, gravity and force are fundamental to our universe's natural laws. What is Gravity? Gravitation refers to the attractive force that...
Geophysical Surveys: Techniques, Applications, and Limitations.
A geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of geophysical signals form the core of geophysical signal processing. The geophysical survey uses various sensing instruments, and data may be collected...
What is Geophysics? Basics and Applications.
Geophysics is the study of the physical properties and processes of the Earth and its surrounding environment using physics, earth science, and technology. Understanding "what geophysics is" gives helpful insight into anything from natural resources to earthquake...
The Basics of Bohr’s Model
Niels Bohr introduced Bohr’s model of the atom as an enhancement of Rutherford’s atomic model. Rutherford had established a nuclear model that described the atom with a positively charged nucleus surrounded by negatively charged electrons. Bohr expanded on this...
