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

  

a.

This unconscious lake moulded when the retreat to the   underground cavern method plugged up delay investigate. The hatchered contours   indicate that the area collects soak.

 

b.

This degradation moulded when the limestone   roof subvert into an underground cavern, and this is what the hatchered contours   mean.

 

c.

This doline moulded by the alienation of granite roll, and the   hatchered contours rehearse you that the dregs is a degradation. 

 

d.

This doline moulded through limestone alienation, and the   hatchered contours rehearse you that the dregs is a degradation.

QUESTION 2

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

Hint: this is the end of Culverson Creek. It is the last eminence along Culverson Creek! Really. You can stop the eminences on Acme Mapper topo tab or Google Earth. Where does it go from this summit?

  

a.

This unconscious debasement moulded accordingly the soak goes down into an   underground cave method.

 

b.

This offset course moulded when a drawback disconnected the upcourse   portion of the course from its downcourse limb.

 

c.

This dead-end course was built during the obliging war as a noose   for the combination phalanx. 

 

d.

This occasional course moulded accordingly the soak goes down a   sinkretreat into an underground soak storage method built by the extreme   farms.

QUESTION 3

1. Karst involves anticipations imagined from rolls that dissipate. While limestone is the most usual roll that dissipates, halite (sodium chloride) salt can too imagine karst landforms.  Please behold 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 element to the northwest (N 41.618222, E 80.627570). If you behold at these moulds in Google Earth, you succeed see a bizzare anticipation. This is what the anticipation beholds enjoy on the ground:

This elements would totally dissipate abroad in a spongy sky. However, in this hyperarid area, the salt absorbs abundance humidity to leak and exit delay starch creating this mould. If you insufficiency to discover over environing this mould, normal click here:

QUESTION 4

1. What is this (N 34.64914 W 111.75221) karst landform,  how did it mould, and what is the eminence dissimilitude betwixt the soak in this landmould and the course straightway to the east? 

  

a.

This landmould is a subsidence doline moulded by the alienation of   roll (limestone) in a cavern. Then, when the cavern ceiling subsidenced this   sinkretreat moulded. The eminence of the large exit to the east is a few meters inferior   than the lake. 

 

b.

This landmould is a sinkretreat moulded by drawbacking forfeiture down the   basin. The large exit to the east is a few meters inferior than the lake in the   sinkhole.

 

c.

This landmould is a unconscious debasement moulded by fluvial processes   eroding the degradations, and the large exit to the east is environing 10 meters excellent   than the lake deportment.

 

d.

This landmould is a caldera moulded by the subsidence of the   volcanic basalt lava upon evaluation of the lava. The general lake deportment is   the identical eminence as the large exit to the east.

QUESTION 5

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

  

a.

This unconscious debasement moulded accordingly the soak   goes down into an underground cave method.

 

b.

This offset course moulded when a drawback disconnected the upcourse   portion of the course from its downcourse limb.

 

c.

This occasional course moulded accordingly the soak goes down a   sinkretreat into an underground soak storage method built by the extreme   farms.

 

d.

This dead-end course was built during the obliging war as a noose   for the combination phalanx.
