Geomorphology test

1. 1Which events perform the most geomorphic work?

   1. ASmall and infrequent events
   2. BMedium and moderately frequent events
   3. CBig but rare events
   4. DEvents occurring once or twice a year
2. 2A geomorphic model is a simplified representation of some aspect of a real landscape that interest a
   geomorphologist.

   1. AVerdadero
   2. BFalso
3. 3Geomorphic models: There are two chief kinds of hardware model: scale models and analogue models.
   [blank_start]Scale[blank_end] are copies of systems and [blank_start]Analogue[blank_end] models are more abstract scale models (maps and remotely sensed images).
   
   [blank_start]Conceptual[blank_end] models are initial attempts to clarify loose thoughts about the structure and function of a geomorphic system.
   Three chief classes of [blank_start]mathematical[blank_end] model assist the study of geomorphic systems: stochastic models, statistical models, and deterministic models. The first two classes are both [blank_start]probabilistic[blank_end] models.

   1. AScale
   2. BAnalogue
   3. CAnalogue
   4. DScale
   5. EConceptual
   6. FMathematical
   7. Gmathematical
   8. HConceptual
   9. Iprobabilistic
   10. JConceptual
4. 4What is geomorphometry or landform morphometry?
   
   Is the [blank_start]mathematical representation[blank_end] of form. Its a brach of geomorphology that studies quantitatively the form of the land surface

   1. Amathematical representation
5. 5In trying to work out the long-term evolution of landforms and landscapes, geomorphologists have three options open to them:

   1. Astratigraphic and environmental reconstruction
   2. Bchronosequence studies (ex. topography)
   3. Cnumerical modelling (ex. predict what happens)
   4. DAll of them
6. 6What are the Earth’s grand ‘cycles’? and are them interconnected?

   1. ARock and water cycles and the biogeochemical cycle
   2. BYes, the water cycle and the rock cycle interact and the biogeochemical cycle (carbon cycle etc) is a fundamental part that sometimes control weathering.
   3. CNo the cycles are independent of each other
   4. D1 and 2 are correct
7. 7Clay and silt particles, even though they are smaller than sand particles, require a higher velocity for erosion to occur.
