Plan and conduct controlled scientific investigations to determine the factors that affect the rate of weathering.
- Earth’s Geosphere
The student will demonstrate an understanding of the internal and external dynamics of Earth’s geosphere.
Evidence indicates Earth’s interior is divided into a solid inner core, a liquid outer core, a solid (but flowing) mantle and solid crust. Although the crust is solid, it is in constant motion and is recycled through time. Plate tectonics is the unifying theory that explains the past and current movements of the rocks at Earth’s surface and provides a coherent account of its geological history. Weathering (physical and chemical) and soil formation are a result of the interactions of Earth’s geosphere, hydrosphere, and atmosphere. All forms of resource extraction and land use have associated economic, social, environmental, and geopolitical costs, risks, and benefits. Natural hazards and other geological events have shaped the course of human history.
