Calcium StepsStep 1: Weathering away of rocks that contain calcium carbonates/ silicatesStep 2: Calcium flows into the ocean, and stays there for one million yearsStep 3: Eventually returns to the land due to precipitation Slide3

Human Dependencies Humans often use calcium as a natural tool to increase soil fertility.Calcium is also vital for humans when it comes to strengthening their bones. i.e. (Milk) Calcium is a mineral necessary for lifeSlide4

Human AffectsIndustrial emissions and land use have changed chemical weathering rates and leached calcium ions out of soils, aggravating plant and microbial community structures. The increased acidity of the ocean waters associated with raising atmospheric concentrations of CO2 has decreased the saturation state of surface water with respect to calcite minerals, causing difficulty for calcitic organisms to produce shells and skeletons. Pollution

Overfishing Slide5

Fun Facts & Study ToolCalcium is the 5th most abundant element in Earth’s crust, present at a level of about 3% in the oceans and soil.The element name “calcium” comes from the Latin word “calcis” meaning “lime” C-Crucial C-

Magnesium CycleFound in high concentrations in limestone and marble As rock particles weather over time, magnesium particles are slowly released into the soilPlants take in nutrients from soil, including magnesium When plants decompose magnesium particles are released into the atmosphere (not in a gas state)Slide7

Magnesium and human impact and dependenceWe, as well as plants and animals need magnesium to function. Humans impact mg cycle through pollutionExample: Acid Rain depletes amount of mg in soilSoil now cannot produce healthy plantsCauses magnesium deficiencies Slide10

Fun facts Magnesium is the central element of chlorophyll Scientists can tell if a plant has a magnesium deficiency by plants colorMg is the basis of early life on earth Alcohol abuse can lead to mg deficiency Slide11
