Earth science

2. - the accelerating integration of national economies, cultures, and societies driven by increased international trade, technology, and information flow.
5. - a social structure that connects individuals through shared values, interests, or goals
6. - entities—ranging from individuals to companies or organisms—that create and supply goods, services, or energy, serving as the foundation of economic or ecological systems
9. - the excessive enrichment of water bodies with nutrients, primarily nitrogen and phosphorus, leading to dense algal blooms, severe oxygen depletion (hypoxia), and "dead zones" that kill aquatic life.
12. method - systematic, empirical process for acquiring knowledge, designed to minimize bias and ensure reproducible results through observation, hypothesis creation, experimentation, and analysis
13. - the phase transition of water from a liquid to a gas (water vapor) that occurs at the surface when molecules gain enough heat energy to overcome surface tension
14. - any liquid or solid water that falls from clouds to Earth's surface, a key part of the water cycle, occurring as rain, snow, sleet, or hail, depending on atmospheric temperatures
15. profile - a vertical cross-section of soil, extending from the surface down to the parent material, revealing distinct layers called horizons

1. - the long-term, balanced integration of environmental health, social equity, and economic vitality to meet present needs without compromising future generations.
3. - the introduction of substances or energy (such as light or heat) into the natural environment in amounts or concentrations that can be harmful for humans, animals, and plants.
4. - an individual or group that purchases or uses goods and services for personal, non-commercial, household, or family needs
7. energy - radiant light and heat from the Sun
8. cycle - the continuous movement of water on, above, and below the Earth's surface, driven by solar energy and gravity
9. - the fundamental capacity to do work, cause motion, or create change, and it cannot be created or destroyed, only transformed.
10. cycle - the continuous, looping flow of a fluid (liquid or gas) driven by density differences caused by temperature variations.
11. - the scientific study of how living things (organisms) interact with each other and with their non-living surroundings (environment)
