GG101 Lecture Notes - Lecture 14: Regolith, Tectonic Uplift, Geomorphology
Document Summary
Chapter 14 weathering, karst landscapes and mass movement. Geomorphology the science of landforms including origin, evolution, form and spatial distribution of landforms. Denudation any process that wears away or rearranges landforms. Principle denudation processes: weathering, mass movement, erosion, transportation, deposition. Exogenic processes develop sequential landscapes of low relief, gradual change and stability. Internal and external processes countering one another act on landscapes simultaneously at different rates. Stronger rock = igneous, metamorphic is stronger than sedimentary but weaker than igneous. Landscapes are open systems as it is always changing with energy flowing in and out of the system along with matter over a long period of time. Inputs of materials to landscapes are precipitation and rocks from tectonic activity. Outputs of materials from landscapes are sediment and water. Inputs of energy are heat energy (solar radiation), potential energy (crustal uplift), kinetic energy (water movement) or chemical energy (atmospheric and other actions within crust)
