Unlocking the Mystery of Arsenic Emission Factors in Earth Science
Human ImpactArsenic is a toxic metalloid found naturally in the earth’s crust. It is widely used in various industries such as agriculture, electronics, and pharmaceuticals. Arsenic can also be emitted into the environment by natural and human activities. The emission factor for arsenic is a critical parameter in determining the amount of arsenic released into the

The Badlands Guardian: A Geological Wonder or a Product of Human Intervention?
Human ImpactThe Badlands Guardian is a geological formation in southeastern Alberta, Canada. It resembles a human head wearing a headdress and has been the subject of fascination and speculation since it was first discovered on Google Earth in 2006. Whether the Badlands Guardian is a natural formation or the product of human intervention has been the

Exploring the Feasibility of Beaming Heat into Space: Geoengineering Possibilities
Human ImpactGeoengineering is a field of science that explores ways to manipulate the Earth’s environment to mitigate the effects of climate change. One of the proposed solutions to reduce the Earth’s temperature is to reflect sunlight back into space or to emit heat from the Earth’s surface into space. This article will focus on the latter

The Causes of Aridification: Understanding Desertification in Earth Science
Human ImpactAridification is a process of land degradation that results in the transformation of fertile land into dry, barren land. This process is also known as desertification and is a growing problem in many parts of the world. Desertification is caused by a combination of natural and human factors, such as climate change, deforestation, and unsustainable

Minimum Temperature for Growing Degree Day (GDD) Calculation: Should it be Based on Daytime or the Entire Day?
Human ImpactGrowing Degree Day (GDD) is a widely used measure of plant growth and development. It is calculated by taking the average temperature of a day and subtracting a base temperature. The resulting value is then accumulated over time to determine the number of GDDs a plant has accumulated. However, there is an ongoing debate as

Can “meanders in meanders” form naturally?
Human ImpactMeandering rivers are a common feature of many landscapes. They are formed by the erosion and deposition of sediment by flowing water. The river channel curves and bends, forming a series of loops or meanders. These meanders can form smaller meanders within themselves, which has led to the question of whether “meanders within meanders” can
