Invasive Species
An invasive species is a non-native species that has been introduced to an ecosystem and has the potential to cause harm to the environment, economy, or human health. These species often outcompete native species and disrupt the balance of the ecosystem.
Characteristics of Invasive Species
- Rapid reproduction
- Adaptability to different environments
- Lack of natural predators
- Ability to outcompete native species for resources
Examples of Invasive Species
Some examples of invasive species include:
- Zebra mussels
- Kudzu vine
- Burmese python
- Cane toad
Impact of Invasive Species
Invasive species can have a range of negative impacts, including:
- Damage to agricultural crops
- Displacement of native species
- Altered ecosystem dynamics
- Spread of diseases
Preventing the Spread of Invasive Species
There are several ways to prevent the spread of invasive species, including:
- Monitoring and controlling introduced species
- Education and public awareness
- Regulations on the import and trade of exotic species
- Restoring and protecting natural habitats

EARTH AND SPACE SCIENCE
Earth’s Systems
Use evidence to explain how different geologic processes shape Earth’s history over widely varying scales of space and time (e.g., chemical and physical erosion; tectonic plate processes; volcanic eruptions; meteor impacts; regional geographical features, including Alabama fault lines, Rickwood Caverns, and Wetumpka Impact Crater).
Provide evidence from data of the distribution of fossils and rocks, continental shapes, and seafloor structures to explain past plate motions.
Use models to explain how the flow of Earth’s internal energy drives a cycling of matter between Earth’s surface and deep interior causing plate movements (e.g., mid-ocean ridges, ocean trenches, volcanoes, earthquakes, mountains, rift valleys, volcanic islands).
