Study Notes
Weathering and Erosion
- Weathering is the breakdown of rocks and other materials on the earth's surface
- There are two types of weathering: mechanical and chemical weathering
- Mechanical weathering involves the physical breakdown of rocks and other materials on the earth's surface
- Chemical weathering involves the breakdown of rocks and other materials through chemical reactions
Sedimentation
- Sedimentation is the process of settling of sediments out of the transporting medium
- It is a slow but continuous process
- The product of weathering is sediment, which is transported by erosion
Erosion
- Erosion is the process of transporting soil and weathered rocks from one place to another
- It is an exogenic process involved in shaping the Earth's surface
Volcanoes
- There are three types of volcanoes based on shape: shield volcanoes, stratovolcanoes, and cinder cones
- Shield volcanoes are characterized by a broad dome with a gentle slope and are mostly made of alternating layers of basaltic lava and cinder accumulation
- Stratovolcanoes are composed of lava and pyroclastic materials and are composed of felsic rocks
- Cinder cones are small cones formed by spattering lava
Volcanic Eruptions
- There are two types of eruptions: lava-rich eruptions and pyroclastic eruptions
- Lava-rich eruptions are characterized by the flow of lava and the formation of fountains and lakes
- Pyroclastic eruptions are characterized by a volcano ejecting ash and larger fragments of broken-up pyroclastic materials
Stress and Faults
- There are three types of stress: tension, compression, and shear
- Tension is characterized by rocks being pulled apart or stretched
- Compression is characterized by rocks being pushed together or compressed
- Faults occur when rocks break or deform due to stress
- Normal faults occur when rocks are pushed apart and one block is forced down
- Reverse faults occur when rocks are pushed together and one block is forced on top of the other
