How Crustal Plates Move: Plate Tectonics
Plate tectonics is the unifying theory of geology. This theory explains how crustal plates move around the surface of the earth, and it allows geologists to find explanations for geologic events such as [more…]

Environmental Science: What Are Acids and Bases?
Many of the interactions that environmental scientists study are the result of acid and base reactions. So what are acids and bases, anyway? Empirically speaking, acids and bases have the following characteristics [more…]

Ten Ways to Live Sustainably
Environmental science is all about finding ways to live more sustainably, which means using resources today in a way that maintains their supplies for the future. Environmental sustainability doesn’t mean [more…]

The Environmental Science of Population Growth Models
Environmental scientists use two models to describe how populations grow over time: the exponential growth model and the logistic growth model. Two important concepts underlie both models of population [more…]

The Search for Alternative Energy
Alternative or renewable energy sources aren’t based on resources that are in limited supply on Earth; instead, they’re captured from processes (such as wind, waves, and sunshine) that are continually [more…]

What Are Photosynthesis and Respiration?
Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy [more…]

Patterns of Ocean Circulation
Environmental scientists study ocean circulation because, along with patterns of air movement in the atmosphere, the movement of water through the oceans helps determine weather and climate conditions [more…]

What Is the Environmental Impact of Petroleum and Natural Gas?
What you know as oil is actually called petroleum or crude oil and may exist as a combination of liquid, gas, and sticky, tar-like substances. Oil and natural gas are cleaner fuels than coal, but they [more…]

Hydropower: Generate Energy with Rivers and Ocean Tides
An important source of alternative energy is hydropower: converting the flow of rivers and ocean waves and tides into electricity through dams and turbines. The best part about both of these water sources [more…]

What Are Prevailing Winds and the Coriolis Effect?
All around the earth, environmental scientists observe fairly steady patterns of wind (or directions of airflow). These prevailing winds, as they’re often called, are the result of the air being moved [more…]

What Is Bioremediation?
One of the most innovative ways to tackle environmental damage by toxins and pollution is to let nature do the dirty work of cleaning up the mess. Certain [more…]

Environmental Science: How to Meet Human Water Needs
Environmental scientists discovered that the second largest consumer of fresh water is you (and every other person in the U.S.). Every day you drink water, brush your teeth, wash your clothes, flush the [more…]

How Biological Communities Work Together
Environmental scientists who study biological communities look at the number of organisms, the number of species, and the distribution of the plants and animals across the environments that they inhabit [more…]

The Dangers of Pesticides in the Environment
The use of pesticides in farming is an important issue to environmental scientists. Farmers encounter many different pests that can damage their crops, and each kind of pest requires different chemical [more…]

What Are Passive and Active Solar Energy Systems?
Humans can capture solar energy directly from the sun through passive and active solar energy systems. Ancient people used passive solar energy systems by building their houses out of stone or clay, which [more…]

What Are Social Justice and Microlending?
One way to reduce poverty and encourage social justice is through microlending. Social justice is the idea that the world has enough resources to meet the needs of everyone but that financial inequality [more…]

What International Agreements Exist to Protect the Environment?
Different nations have come together on their own accord to create international agreements about how to maintain, protect, and care for the earth’s natural resources. These international agreements and [more…]

Ten Real-Life Examples of the Tragedy of the Commons
The phrase tragedy of the commons, first described by biologist Garrett Hardin in 1968, describes how shared environmental resources are overused and eventually depleted. He compared shared resources to [more…]
