Geologic Time Quiz

Earth Science Essentials

• Environmental Geology integrates chemistry, physics, and biology in the context of Earth's systems.
• Earth materials typically include rocks, minerals, water, and soil; items like plastic are NOT considered Earth materials.

Geologic Hazards Examples

• Earthquakes, landslides, volcanic eruptions, and tsunamis are recognized as significant geologic hazards.
• Floods, while often tied to weather rather than geological processes, can also be categorized within the broader spectrum of geologic hazards.

Environmental Issues in Haiti

• Environmental degradation in Haiti is driven by factors such as intense deforestation primarily for agricultural land and fuelwood.
• Main consequences of deforestation include increased soil erosion, loss of biodiversity, and heightened vulnerability to natural disasters.

Key Concepts in Geology

• Geology is defined as the study of the Earth, including its structure, composition, and processes.
• Environmental Geology specifically examines interactions among geological processes and human activity, incorporating aspects from environmental science, physics, and biology.

Land Use Planning

• Main purpose of land use planning is to ensure sustainable development and appropriate land management to balance ecological health and human needs.

Ecosystem Concerns

• A closed system of stagnant water may result in problems like algal blooms, which can deplete oxygen and harm aquatic life, indicating the importance of water circulation for ecosystem health.
