Procedure: write objectives, rapid mass wasting, slow mass wasting, talus slope on board explain that the downhill movement of sediments is called mass wasting have students give examples of mass wasting and write them on the board. Mass wasting occurs on both terrestrial and submarine slopes if you are unfamiliar with the topic of mass wasting, this website , provided by professor chuck demats at the department of geoscience, university of wisconsin-madison, is a great resource. Mass wasting is a general term for a variety of processes by which earth materials move downslope as a result of gravity the actual process of downslope motion is referred to as mass movement. The 1919 and 1985 mass-movement events were both triggered by volcanic eruptions identify at least two natural contributing variables from table 2-1—speciﬁ c to volcanic slopes—that contributed to these mass-movement events.
This complex area of mass wasting is characterized by earth flow movement within the main body of the mass, and slumping from the point of origin all the way to the end of the mass where it meets the pacific ocean. A d lab course, physical geology is an in-depth study of how the earth is constructed and the processes that have formed the earth and continue to change the earth's surface topics will include: the understanding of the. Tiffany dunmire october 19, 2016 mass wasting lab abstract: in this experiment, i believe that the different between wet and dry sediment will explain how natural processes occur and affect different kinds of sediments.
Mass wasting, which is sometimes called mass movement or slope movement, is defined as the large movement of rock, soil and debris downward due to the force of gravity. Mass movement along the shores of lake mi are investigated in the field, lab, and through gis analysis of digitized aerial photography students assess strength characteristics of unconsolidated sediment in the field and survey the morphology of the movement, and take samples for laboratory analysis of the fine fraction. Geology 103 lab 09 mass wasting and erosion michael stewart, 2006 3 1) consider the mountains that formed when africa collided with north america.

A landslide, or, more properly, a mass wasting event occurs when earth materials, under specific pre-existing conditions, move downslope comparatively rapidly after some event (called a trigger . Eas 2600 lab 9 introduction to mass wasting spring 2014 mass wasting a landslide is both a variety of landforms and a downslope movement of soil, fill and/or rock. Ess 210 lab 12: mass wasting 3 on the map, the slumgullion earthflow is labeled slide but it did not move as a coherent block we first need to identify the extent of this earthflow. Lab module learning objectives after successfully completing this module, you should be able to accomplish the following tasks: identify erosional processes and features created by weathering and mass wasting.

Key geol 103 writing assignment 5: mass wasting name ___key_____ lab section: monday or tuesday (circle one) to be counted, must be turned in by friday november 1. Mass wasting is a broad term covering all the different processes by which gravity moves sediment (sand, regolith, rocks) down slopes some well-known examples are gullies and recurring slope lineae (rsl.
Geol 108 lab #6 landslides and mass wasting week of october 8-12, 2012 part i slope & gravity the main force responsible for mass wasting is gravity gravity is the force that acts. Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity, but frequently with characteristics of a flow as in debris flows and mudflows. 1 mass wastingmass wasting the downslope movement of rock, regolith, and soil under the direct influence of gravity gravity is the controlling force.
Mass wasting processes also occur on steep slopes in the ocean basins a slope failure can occur due to over-accumulation of sediment on slope or in a submarine canyon, or could occur as a result of a shock like an earthquake. Geology taiwan consists of an active mountain belt, produced by the collision of the eurasian and philippine sea plates, which forms the spine of the island the mountains are being eroded by the many landslides caused by earthquakes and typhoons. Describe and identify different types of mass wasting, their characteristics, and associated landforms and, discuss mechanisms that may trigger mass wasting events b types of mass movement.
