Periodic Exam 1st Quarter Flashcards
Stidy of the flow of matter
Rheology
Earth that can be divided into 5 mechanically
Lithosphere
Asthenosphere
Mesospheric mantle
Outer core
Inner core
Chemically
Crust
Upper mantle
Lower mantle
Outer core
Inner core
Outer solid part (70-100km)
Lithosphere
Highly viscous, hotter and ductile
Asthenosphere
Thinnest layer, outer most layer (5-10km thick)
Crust
Discover the separation of mantle from crust
Andrija mohorovicic
Occurs at average depth of km beneath the ocean basin
The moho
Highly viscous layer (660km)
Upper mantle
Extend form just where the upper mantle
Lower mantle
Last and innermost layer
Core
Represent about 4%of the mantle or liquid portion
Outer core
Deepest region (5,000-6,000C)
Inner core
Current
Dynamo effect
Effect are quite small
Geomagnetic flips or geomagnetic reversal
Scientific study of landforms
Geomorphology
Study of the current terrain features
Topography
Natural physical features (take millions years to be created)
Landform
New island dubbed on nov 21,2013 (600miles) tokyo, japan
Nii-Jima
Chemical and mechanical action of the wind
Aeolian landforms
Mounds or small hills (1-10 heights)
Dunes
Predominantly slit sized “cat step”
Loess
Shape of mushroom
Mushroom rock or rock pedestal
Exclusive erosional
Erosional landforms
