Demographers use census data, surveys, and statistical models to analyze the size, movement, and structure of populations. 👤Demography is the statistical study of human populations. Demography examines the size, structure, and movements of populations over space and time. It uses methods from history, economics, anthropology, sociology, and other fields. Demography is useful for governments and private businesses as a means of analyzing and predicting social, cultural, and economic trends related to population. 👥While basic demographic studies, such as  censuses , were conducted in the ancient world as far back as 6,000 years ago, demographers as we know them, such as John Graunt from the United Kingdom, came about in the 16th century. The earliest statistical studies were concerned mostly with  mortality  (how many people died and at what age). Through studying baptism and burial records, Graunt could es...

BIOGEOCHEMICAL CYCLES

🌱 CARBON CYCLE. What is the carbon cycle? The carbon cycle is nature's way of  recycling carbon atoms . Carbon is the  foundation for all life on Earth . The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Human activities have a tremendous impact on this cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer massive quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising — it is now greater than at any time in the last 3.6 million years . 🌌 NITROGEN CYCLE. Process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms. Process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. 🔥 PHOSPHORUS CYCLE. Over time, rain and  weathe...
