What are the major elements necessary for plant growth and development?
The major elements necessary for plant growth and development include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, which are essential macronutrients. Additionally, plants require micronutrients such as iron, manganese, zinc, copper, molybdenum, boron, and chlorine in smaller quantities for optimal health and growth.
What are the major elements found in the Earth's crust?
The major elements found in the Earth's crust are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
What are the major elements present in the human body?
The major elements present in the human body are oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
How do major elements influence the quality of water resources?
Major elements, such as nitrogen and phosphorus, influence water quality by contributing to nutrient pollution, leading to eutrophication and harmful algal blooms. This process can deplete oxygen levels and harm aquatic life. Balanced concentrations are essential to maintain healthy ecosystems and safe water for human use.
What are the major elements that contribute to air pollution?
The major elements that contribute to air pollution include particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), volatile organic compounds (VOCs), and ozone (O3). These pollutants originate from industrial activities, combustion of fossil fuels, vehicle emissions, and agricultural practices.
