GEOB 103 Study Guide - Quiz Guide: Luminescence Dating, Dendrochronology, Return Period
Document Summary
Question 2 (2 points) list two uses of gps that are important for geomorphologists: (1) identifying elevation change, (2) measuring uplift, (3) determing surface roughness, (4) locate fault movement, . A dem is a digital elevation model, where the topographic elevation of a certain area is mapped. Nowadays dems are usually handled through gis (geographic information systems) which are software specifically designed to visualize and manipulate digital landscape data. Question 4 (2. 5 point) explain the difference between relative dating and numerical dating methods: As the word suggests, relative dating methods use stratigraphy to date landscapes according to their relative age, saying that a certain landform is older or younger than another one. Instead, numerical dating methods give estimates of more or less precise chronological ages. Question 6 (1 point) dendrochronology can be used to date: (a) river terraces (b) recent glacial activity (c) recurrence intervals of wildfires (d) only a and c (e) a, b and c.
