How do we know what Earth’s core is made of?
Earth SystemLesson 1: Introduction to the Earth’s Core The Earth’s core is a mysterious and crucial part of our planet. Located at the center, beneath the crust and mantle, it plays a vital role in shaping the Earth’s structure, magnetic field, and geological processes. Understanding the composition of the Earth’s core is essential to unraveling the

Exploring Earth’s Hidden Divisions: Beyond Hemispheres in Earth Science
Earth SystemAre there other divisions of the earth besides hemispheres? The Concept of Hemispheres The concept of dividing the Earth into hemispheres is based on the idea of dividing the planet into two equal halves, primarily based on geographic coordinates such as the equator and the prime meridian. These divisions, known as the Northern and Southern

The Earth’s Altitude Limit: Unveiling the Mystery Behind the Lack of Mountains Beyond 10 km
Earth SystemThe Earth’s Crust and Plate Tectonics The Earth’s crust is the outermost layer of the Earth and consists of solid rock. Beneath the crust is the mantle, which is a semisolid layer. The Earth’s crust is not a single continuous piece, but is made up of several large and small pieces called tectonic plates. These

Unraveling the Mystery: A Guide to Understanding VARIANT-IDs in CMIP6 Metadata
Earth SystemThe Coupled Model Intercomparison Project Phase 6 (CMIP6) is a global effort to coordinate and standardize climate model simulations. CMIP6 includes a large number of climate models and simulations, each of which is identified by a unique identifier called a VARIANT-ID. The VARIANT-ID is an essential part of the CMIP6 metadata and is used to
