Exploring Plate Tectonics through Time: An Interactive Online Demonstration with Google Earth
Geology & LandformPlate tectonics is the scientific theory that explains how the outermost layer of the Earth is made up of plates that move and interact with each other. It is a fundamental concept in Earth science and helps us understand a wide range of geological phenomena, from earthquakes and volcanic eruptions to the formation of mountain
Calculating the Horizontal Distance to the Visible Horizon: Exploring the Effects of Earth’s Curvature on Sea Level Observations
Water BodiesObserving the horizon is a common sight for people who live near the coast or are on a boat. The horizon is the apparent line that separates the sky from the land or sea. What many people do not realize is that the apparent horizon they see is not actually flat, but curved. This curvature
Mastering Glaciology: Calculating Glacier Mass Balance for Accurate Climate Projections
Polar & Ice RegionsGlaciers are one of the most fascinating and important natural phenomena on Earth. They play a critical role in shaping the landscape and influencing the climate of our planet. However, the study of glaciers is a complex and multidisciplinary field that requires a deep understanding of various physical, chemical, and biological processes. One of the
The Basics of 0 Degree Isotherm and Its Calculation in Snow Science
Polar & Ice RegionsIn snow science, the 0-degree isotherm is an important concept that helps determine the temperature profile of the snowpack. The 0-degree isotherm, also known as the freezing level, is the height or elevation at which the temperature is 0 degrees Celsius (32 degrees Fahrenheit). The location of this isotherm is influenced by factors such as
Assessing the Credibility of Glaciology Journals: A Guide for Earth Scientists
Polar & Ice RegionsGlaciology is a branch of Earth science that deals with the study of glaciers, ice sheets, and other forms of ice on Earth. With the growing interest in climate change and its impact on the cryosphere, there has been an increase in the number of journals publishing research related to glaciology. However, not all journals
Unlocking the Power of Remote Sensing and GIS in Earth Science
Geology & LandformWhat is remote sensing? Remote sensing is the science of obtaining information about the Earth’s surface without physically touching it. This is achieved by using various sensors mounted on satellites, aircraft, or ground-based platforms that collect data about the Earth’s surface in the form of images or other measurements. The data collected by these sensors
