Oceanic vs Continental Plates: Which is Heavier in Plate Tectonics?
Geology & LandformPlate tectonics is the theory that explains the movement of the Earth’s lithosphere, the rigid outer shell that includes the crust and uppermost part of the mantle. The lithosphere is divided into several large pieces, or plates, that move relative to each other. The movement of these plates gives rise to various geological phenomena, including
Exploring the Link Between Asteroid Impacts and Magma Plumes: A Review of Earth Science Research
Geology & LandformFor many years, scientists have been interested in understanding the relationship between asteroid impacts and hotspots, particularly as it relates to the formation of magma plumes. While this is still a subject of debate and ongoing research, recent studies have shed new light on the subject. In this article, we will explore the latest findings
Exploring the Seismic Discontinuity between the Lithosphere and Asthenosphere: Fact or Fiction?
Geology & LandformThe lithosphere and asthenosphere are two important layers of the Earth’s interior. The lithosphere is the rigid outermost layer of the Earth, which includes the crust and the uppermost part of the mantle. The asthenosphere is the weak and ductile layer below the lithosphere, extending to a depth of about 700 km. The lithosphere and
Why Do Rocks Fracture Along Specific Planes or Regions?
Geology & LandformFracturing is a common phenomenon in rocks caused by various factors such as tectonic stresses, temperature changes, and pressure variations. One curious aspect of fracturing, however, is that it often occurs along a specific plane or region of the rock, rather than uniformly throughout the rock mass. This article explores the reasons for this phenomenon
India’s Collision: Impacts on Mountain Building Across Asia
Geology & LandformThe collision of the Indian subcontinent with the Eurasian plate is one of the most significant tectonic events in the history of the Earth. This event began about 50 million years ago and continues to this day, giving rise to the Himalayan mountain range and the Tibetan Plateau. The Himalayas and Tibet are known for
Understanding the Effect of Non-Cardinal Directions on True Bearing: Geodetic Considerations
Geology & LandformIn navigation, true bearing is the direction in which an object or location is located, measured in degrees clockwise from true north. However, on a globe, the true bearing of an object can change as the observer moves in a non-cardinal direction. This phenomenon is commonly referred to as “geodetic azimuth variation”. Geodetic azimuth is
