AP Environmental Science ♻️ The three principles, or pillars, of the sustainability of life on this planet are 1) solar energy 🌞 , 2) biodiversity 🐸 , and 3) nutrient cycling 🔄 . Each of these themes interacts with one another and earth's systems to sustain life.
The AP Environmental Science framework is organized into nine commonly taught units of study that provide one possible sequence for the course.
Wood is commonly used as a fuel source as firewood or charcoal. Developing countries rely on the use of biomass as a fuel source because it is easily accessible and can be replenished. Biomass is considered renewable if only the rate of replenishing the sources is faster than usage.
Which of the following best explains why top predators can have up to 60 times as much of persistent organic pollutant (POP) as their prey and up to 600 times as much of the pollutant as producers? A. POPs accumulate in the body fat of living organisms. POPs increase in concentration as they move up the food chain.
The AP® Environmental Science exam includes 80 multiple-choice questions and 3 free-response questions. The free-response questions (FRQ) include a question to design an investigation and analysis and solution to environmental problem questions with and without calculations.
The AP Environmental Science Exam assesses student understanding of the science practices and learning objectives outlined in the course framework. The exam is 2 hours and 40 minutes long and includes 80 multiple-choice questions and 3 free-response questions.
The world is dependent on fossil fuels because they are easy to access. The three main types of fossil fuels are coal, oil (petroleum) and natural gas. Coal ➱ Formed from millions of years of decomposed plant buildup, coal is made of of carbon, hydrogen and water.
Biofuels. Fuels, such as ethanol or methanol, that are created from the fermentation of plants or plant products.
Wood is commonly used as fuel in the forms of firewood and charcoal. It is often used in developing countries because it is easily accessible. Peat is partially decomposed organic material than can be burned for fuel. Three types of coal used for fuel are lignite, bituminous and anthracite.
Which of the following factors would most likely contribute to the conditions observed in the Long Island Sound? The sound has large numbers of phytoplankton blooms that are decomposing and consumed by respiring bacteria.
Given that beak size is genetically determined, which of the following hypotheses is the most likely explanation for the differences in data between the islands? The types of food found on the two islands exert selective pressure on beak size. Which of the following is the best example of a keystone species?
Which of the following best describes legislation that could be used to address problems with overfishing? The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES ) uses trade rules to protect commercially valuable species.
Environmental science is interdisciplinary ; it embraces a wide variety of topics from different areas of study. Yet there are several major unifying constructs, or themes, that cut across the many topics included in the study of environmental science.
Environmental science is interdisciplinary; it embraces a wide variety of topics from different areas of study. Yet there are several major unifying constructs, or themes, that cut across the many topics included in the study of environmental science.
1. Science is a process. • Science is a method of learning more about the world. • Science constantly changes the way we understand the world. 2. Energy conversions underlie all ecological processes. • Energy cannot be created; it must come from somewhere.
The goal of the AP Environmental Science course is to provide students with the scientific principles, concepts, and methodologies required to understand the interrelationships of the natural world, to identify and analyze environmental problems both natural and human-made, to evaluate the relative risks associated with these problems, ...
