GEO- Chapter 14 1. Processes and landforms o Topography: distribution of landscape o Landforms: surface terrain features o Geomorphology: landforms and development of features dealing with igneous processes and tectonics Relief terrain Low: flat land High: rockies o Processes Endogenic: increases surface relief Exogenic: decreases surface relief Ex. Erosion, deposition o Punctuated equilibrium Ex. Earthquakes, floods, volcano eruptions Volcanism: explosion Plutonism: underground o Explosive: big boom o Effusive: pouring lava o Nature of volcanic eruption Mineral composition determines the nature Silica-rich felsic: cool, thick, and resistant to flowing Mafic: flows easily Pressure caught underground makes the explosion Pyroclastic material: ash and tephra 2. Volcanic landforms o Lava flows: Basalt and joints (fractures0 pahoehoe: hardening crust Aa: sharp edged blocks Fissures: lava pouring out of fractures Flood basalts: lava flowing up
