Study Notes
Geological Processes
- Geologic processes can drastically alter rocks over short and long periods of time
Internal Geological Processes
- Processes that originate from within the Earth itself are referred to as internal geological processes
Learning Objectives
- After completing the learning material on weathering and Earth's interior, students are expected to have a thorough understanding of the topics
Academic Support
- Students who encounter difficulties with the lessons and activities should seek assistance from their teachers or peers
- If students need a little assistance with the learning material, they should review the previous topics and seek help when needed
Weathering Processes
- Frost wedging is a process that causes rocks to expand and fracture due to the freezing of water in cracks and crevices
- Mechanical weathering is a type of weathering that breaks rocks down into bits due to physical force, similar to physical change
- Exfoliation is the process where overlying rocks at the surface are removed, causing the underlying rocks to expand and fracture
Factors Affecting Weathering
- Living organisms are not involved in the weathering of rocks
- High temperature causes rocks to expand and fracture when exposed to it
Frost Wedging
- Frost wedging is most prevalent in cold regions
- Frost wedging leads to the formation of potholes in roads during winter
Chemical Composition
- Physical or mechanical weathering does not alter the chemical composition of rocks
Soil Formation
- One of the processes that lead to soil production is mechanical weathering
Exfoliation
- When the pressure diminishes from overlying rocks at the surface, the underlying rocks expand and fracture
