Why North America Experienced a Harsher Ice Age than Eurasia: Exploring Ice Sheet Dynamics
Polar & Ice RegionsThe Pleistocene Epoch, commonly known as the Ice Age, was a time when glaciers covered much of the Earth’s surface. During this period, which lasted from about 2.6 million to 11,700 years ago, the climate was much colder than today and the polar ice caps were much larger. While the Ice Age affected many parts
The Equator’s Effect on Throwing a Stone: How Much Farther Does it Go in the Direction of Rotation?
Natural EnvironmentsThe equator is a unique place on Earth where the planet’s rotational speed is greatest. When you stand at the equator, the ground beneath your feet is moving at approximately 1,037 miles per hour (1,670 km/h). This speed is due to the Earth’s rotation on its axis, which completes one full revolution every 24 hours.
The Science Behind Humanure: How It Improves Soil Texture
Natural EnvironmentsHuman dung, or human waste, has been used as a fertilizer for centuries. In addition to its nutrient content, humanure has been shown to improve soil texture, making it “fluffier” and more conducive to plant growth. This article explores the science behind why manure has this effect on soil texture. The role of organic matter
Classifying Variables in Earth Science: Exploring the Need for a Standardized Metadata Attribute for Classification Systems
Energy & ResourcesThe Importance of Metadata in Earth Science Metadata are essential to geoscience research because they provide information about the data, including how it was collected, processed, and analyzed. Metadata allows researchers to evaluate and understand the quality of the data, assess its suitability for their research, and ensure that the data are used appropriately. In
Unraveling the Mystery: Tectonic Features Arising Outside Collision and Subduction Zones
Geology & LandformTectonic plates are constantly moving and colliding with each other, resulting in various geological features such as mountain ranges, ocean trenches, and volcanic activity. These features are usually associated with collision and/or subduction zones, where two plates come together and one plate is forced underneath the other. However, there are instances where these features are
Exploring the Chromium Content of Common Limestone: A Mineralogical Analysis
Geology & LandformLimestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3), but it may also contain traces of other elements, such as chromium. Chromium is a chemical element commonly found in the Earth’s crust, where it occurs in various minerals, including chromite, ferrochrome, and chromite sand. The presence of chromium in limestone is of interest
