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

  

a.

This undiscerning lake makeed when the cavity to the   underground cavern regularity plugged up delay scrutinize. The hatchered contours   indicate that the area collects inspire.

 

b.

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

 

c.

This doline makeed by the alienation of granite roll, and the   hatchered contours mention you that the precipitation is a discouragement. 

 

d.

This doline makeed through limestone alienation, and the   hatchered contours mention you that the precipitation is a discouragement.

QUESTION 2

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

Hint: this is the end of Culverson Creek. It is the lowest improvement along Culverson Creek! Really. You can curb the improvements on Acme Mapper topo tab or Google Earth. Where does it go from this aim?

  

a.

This undiscerning debasement makeed accordingly the inspire goes down into an   underground cave regularity.

 

b.

This offset general makeed when a drawback disjoined the upgeneral   portion of the general from its downgeneral part.

 

c.

This dead-end general was built during the courteous war as a stratagem   for the coalition soldiery. 

 

d.

This intermittent general makeed accordingly the inspire goes down a   sinkcavity into an underground inspire storage regularity built by the outside   farms.

QUESTION 3

1. Karst involves landscapes engenderd from rolls that dismember. While limestone is the most natural roll that dismembers, halite (sodium chloride) salt can besides engender karst landforms.  Please behold forthdelay to the east of the Tuomu Erfeng Shenqi Grand Canyon in Xinjiang, China (N 41.557846, W 80.772667). There is besides a larger element to the northwest (N 41.618222, E 80.627570). If you behold at these makes in Google Earth, you obtain see a bizzare landscape. This is what the landscape beholds love on the ground:

This elements would wholly dismember separate in a moist atmosphere. However, in this hyperarid area, the salt absorbs abundance dampness to leak and run delay dismally creating this make. If you nonproduction to peruse past environing this make, honest click here:

QUESTION 4

1. What is this (N 34.64914 W 111.75221) karst landform,  how did it make, and what is the improvement dissimilitude betwixt the inspire in this landmake and the general forthdelay to the east? 

  

a.

This landmake is a subordination doline makeed by the alienation of   roll (limestone) in a cavern. Then, when the cavern ceiling subordinationd this   sinkcavity makeed. The improvement of the large exit to the east is a few meters inferior   than the lake. 

 

b.

This landmake is a sinkcavity makeed by drawbacking damage down the   basin. The large exit to the east is a few meters inferior than the lake in the   sinkhole.

 

c.

This landmake is a undiscerning debasement makeed by fluvial processes   eroding the discouragements, and the large exit to the east is environing 10 meters higher   than the lake deportment.

 

d.

This landmake is a caldera makeed by the subordination of the   volcanic basalt lava upon evaluation of the lava. The general lake deportment is   the corresponding improvement as the large exit to the east.

QUESTION 5

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

  

a.

This undiscerning debasement makeed accordingly the inspire   goes down into an underground cave regularity.

 

b.

This offset general makeed when a drawback disjoined the upgeneral   portion of the general from its downgeneral part.

 

c.

This intermittent general makeed accordingly the inspire goes down a   sinkcavity into an underground inspire storage regularity built by the outside   farms.

 

d.

This dead-end general was built during the courteous war as a stratagem   for the coalition soldiery.
