Hi All,
I have been very remiss about writing. Sorry! I met Sam and Simon in Bangkok last week......the flooding wasn't too bad at that time. Sam said he almost didn't recognize me becasue I had lost some weight. I think just about everyone was thinner by the end of the trek. We headed off to Kho Phi Phi, one of the most beautiful islands I've ever been to. Ok 8th graders, extra credit: The islands are a great example of Karst Topography. So, what is karst topography? How does it form? Where are there examples in Michigan of Karst landforms? I'll award points when I return just before Thanksgiving. I hope things are great at BCMS!
We came back to Bangkok yesterday and the flooding was much worse. We managed just fine though. We are now in Chaing Mai in the northern part of Thailand. I'm going to try and download some pictures......the two computers I found in Bhutan were too slow!

Karst topography is created when groundwater dissolves sedimentary rock. There are exaples of it in Ann Arbor.
Hope you had fun Mrs. Sharp.!(:
Karst is a distinctive topography in which the landscape is largely shaped by the dissolving action of water on carbonate bedrock (usually limestone, dolomite, or marble).
As rain falls through the atmosphere, it picks up CO2 which dissolves in the droplets.
Once the rain hits the ground, it percolates through the soil and picks up more CO2 to form a weak solution of carbonic acid: H2O+CO2=H2CO3.
The infiltrating water naturally exploits any cracks or crevices in the rock.
Over long periods, with a continuous supply of CO2 - enriched water, carbonate bedrock begins to dissolve.

??????????????????????????????
We all miss you Mrs. Sharp. I hope the trip has been really fun. I cant wait until you come back.:) It looks beautiful of the pics that you have posted. I want to see it for myself. Well i guess i will see you when you get back.
Hope you had fun, Mrs. Sharp! The pictures are beautiful and I can't wait to hear the stories!

Karst topography occurs when a landscape is marked by underground drainage patterns. In such regions there may be little or no surface drainage. The word Karst, or Classical Karst, is the English name for Kras, a Slovenian region that rests on a limestone plateau.
