1. What is this karst landcontrive (N 47.21181 W 121.94142), how did it contrive, and what do the hatchered contours balance (that you can see in Acme Mapper topo tap)?

  

a.

This unseeing lake contriveed when the hole to the   underground cavern arrangement plugged up after a while examine. The hatchered contours   indicate that the area collects impart.

 

b.

This discouragement contriveed when the limestone   roof demolish into an underground cavern, and this is what the hatchered contours   mean.

 

c.

This doline contriveed by the disruption of granite cast, and the   hatchered contours promulgate you that the colonization is a discouragement. 

 

d.

This doline contriveed through limestone disruption, and the   hatchered contours promulgate you that the colonization is a discouragement.

QUESTION 2

1. What is this karst landcontrive (N 37.94188 W 80.45261) and how did it contrive?

Hint: this is the end of Culverson Creek. It is the last superiority concurrently Culverson Creek! Really. You can hinder the superioritys on Acme Mapper topo tab or Google Earth. Where does it go from this aim?

  

a.

This unseeing degradation contriveed owing the impart goes down into an   underground cave arrangement.

 

b.

This offset course contriveed when a error disconnected the upcourse   portion of the course from its downcourse member.

 

c.

This dead-end course was built during the polite war as a pitfall   for the connection phalanx. 

 

d.

This intermittent course contriveed owing the impart goes down a   sinkhole into an underground impart storage arrangement built by the excluded   farms.

QUESTION 3

1. Karst involves fields inventd from casts that disintegrate. While limestone is the most regular cast that disintegrates, halite (sodium chloride) salt can too invent karst landforms.  Please face straightway to the east of the Tuomu Erfeng Shenqi Grand Canyon in Xinjiang, China (N 41.557846, W 80.772667). There is too a larger characteristic to the northwest (N 41.618222, E 80.627570). If you face at these contrives in Google Earth, you allure see a bizzare field. This is what the field faces enjoy on the ground:

This characteristics would fully disintegrate loose in a damp air. However, in this hyperarid area, the salt absorbs abundance humidity to drip and career after a while ruefulness creating this contrive. If you insufficiency to interpret further environing this contrive, fitting click here:

QUESTION 4

1. What is this (N 34.64914 W 111.75221) karst landform,  how did it contrive, and what is the superiority unlikeness among the impart in this landcontrive and the course straightway to the east? 

  

a.

This landcontrive is a mitigation doline contriveed by the disruption of   cast (limestone) in a cavern. Then, when the cavern ceiling contracted this   sinkhole contriveed. The superiority of the large drift to the east is a few meters inferior   than the lake. 

 

b.

This landcontrive is a sinkhole contriveed by erroring detriment down the   basin. The large drift to the east is a few meters inferior than the lake in the   sinkhole.

 

c.

This landcontrive is a unseeing degradation contriveed by fluvial processes   eroding the discouragements, and the large drift to the east is environing 10 meters better   than the lake demeanor.

 

d.

This landcontrive is a caldera contriveed by the mitigation of the   volcanic basalt lava upon evaluation of the lava. The running lake demeanor is   the similar superiority as the large drift to the east.

QUESTION 5

1. What is this karst landcontrive (N 37.81090 W 80.49637) and how did it contrive? Hint: this is the end of Milligan Creek. Where does it go from this aim?

  

a.

This unseeing degradation contriveed owing the impart   goes down into an underground cave arrangement.

 

b.

This offset course contriveed when a error disconnected the upcourse   portion of the course from its downcourse member.

 

c.

This intermittent course contriveed owing the impart goes down a   sinkhole into an underground impart storage arrangement built by the excluded   farms.

 

d.

This dead-end course was built during the polite war as a pitfall   for the connection phalanx.
