High School Environmental Science Vocabulary

Understanding High School Environmental Science Vocabulary

This vocabulary set shows that environmental science is about connected systems. A change in air, water, soil, or living things can spread through an ecosystem. Coral reefs are a clear example.

Coral polyps depend on zooxanthellae for much of their energy. When water becomes too warm or other stress grows, coral bleaching can occur. Rising carbon dioxide creates a second problem.

Some of that gas enters seawater, forms carbonic acid, lowers pH, and leaves fewer carbonate ions available. This makes calcification harder, so reefs may struggle to grow or repair damage. Learning this chain helps students move beyond isolated facts toward causes and effects.

Many terms focus on biodiversity and the conditions that support it. A food web shows that species rely on many feeding links, not one simple chain. Each species has an ecological niche, meaning its place and role in the system.

Habitat fragmentation can isolate populations in small patches. Small populations may have less access to mates, food, or safe shelter. Wildlife corridors can reconnect those patches and allow movement between them.

Protected areas and buffer zones reduce pressure from development near important habitats. Native species often fit long-standing food webs, while invasive species can disrupt them.

These ideas explain why an endangered species is rarely protected by saving one individual alone. Its habitat, resources, and relationships matter too.

The deck connects land processes to climate processes. Soil horizons show that soil has layers with different materials and functions. Topsoil and humus hold nutrients and water that plants need.

Infiltration moves water into the ground, while soil compaction reduces that movement. This can increase runoff and erosion. Wetlands with hydric soils can store water, cycle nutrients, and provide habitat.

Fire vocabulary adds another connected process. Wildfire needs the parts of the fire triangle, including heat, oxygen, and fuel. Fuel load affects fire intensity.

Some plants use serotiny, holding seeds until fire helps release them. After disturbance, succession describes how communities change over time. These processes shape ecosystems rather than simply destroying them.

Climate terms help explain changes that happen across large areas and long periods. Greenhouse gases absorb infrared radiation and change Earth’s energy balance. Radiative forcing describes that change in balance.

Albedo matters because bright surfaces reflect more incoming energy than dark surfaces. The carbon cycle links forests, soils, oceans, fossil fuels, and the atmosphere. Microplastics show another human impact that can move through these same systems.

Primary microplastics are made small, while secondary microplastics form when larger plastic breaks apart. Study these words in connected groups. Draw arrows from carbon dioxide to ocean acidification, then to carbonate ions, calcification, corals, and food webs.

For every term, practice stating a cause, an effect, and one realistic example. This builds the skill needed for environmental science explanations.
