I usually just read the questions, if I need to know some other stuff then I just skim back, but usually you can just get it by reading the questions.

thats exactly wat i do

[cooltiger]

Of course you do, your my partner.

i know, just felt like mentioning that

At what level do u need to know profiling?? We're really lost.

Also, besides doing tests, what are the other best study tactics??

HELP!!

Level? You just need to know how to profile. I might be able to help you, but profiling isn't my strong point either.

Okay, so the test will tell you two places. Imagine that there's a straight line between them (or lightly draw the line on the map so that you can erase it later.) Then, after finding out the countour interval, right down all of the elevations that are found between the two in a column going from lowest elevation on the bottom, to highest elevation on the top. Then you just kind of graph the elevations on there. It can be difficult to get the exact distances between the countour lines on the porfile exactly right. Just estimate when putting the points on there. Then, connect the points with somewhat curvy lines to try and replicate the elevation changes of the earth.

If I made a mistake somewhere, somebody please correct me. I haven't mastered profiling yet.

Edit: If I wasn't clear, on the profile, the X axis is distance and the Y axis is elevation.

Thank u soooo much you have no idea how lost we were

That's not exactly the best way to profile.

Here's how we used to do it:

Take a piece of printer paper, and line up the 2 points, placing big marks at each end point. Now, going along between the endpoints, at every contour line you see, place a little dash on the edge of the paper at the spot. So by the end you'll have a sheet of paper with a bunch of little dashes running along the edge of the sheet. It is also helpful to record the elevation of maybe every third or fourth mark so you don't lose your spot.

Now, figure out your min and max elevation between the two points by looking at the map. Set up an appropriate scale on your chart, with elevation going up the Y axis and just location along the X axis.

Take your piece of paper, and line up the left end point with the x=0 spot on your chart. Make a little dot on the appropriate line of elevation. Now, keeping the left end point on the x=0 spot, go through and place a little dot at every elevation dash you made on that sheet of paper. It can be difficult to keep track of what exact elevation each dash is for, so be careful. Once you're done, you will have a series of dots mapping out a nice curve, perfectly scaled to match the topo map. All that's left is to connect the points as smoothly as realistically as possible and you'll have a perfect profile.

Yeah, your way does seem easier, and maybe is even a little bit faster. My way worked for me when I practiced profiling, but if I have to profile in the competition (9 days) I'll definitely use your way. Thanks.

[nerdygrlz789]

yeah, both of ur ways seem easier than the print-out that we have in our binders. thx so much 4 all yr help!!

good luck at regionals!!
