Answer 1

OK. Know what the contour interval is?

Answer 2

Yes 20

Answer 3

Good. OK, then, do you know how to find #1?

Answer 4

yes, is it c

Answer 5

Yep. Kk. So, which are you having trouble with them?

Answer 6

then...

Answer 7

numbers 3, 4 and so on

Answer 8

the other maps are confusing

Answer 9

OK, for 3, you have a legend in the lower right of the map. You use that and some ruler or other measure to get the distance.

Answer 10

ok

Answer 11

7km

Answer 12

Yah, that looks closest to me.

Slope is the rate of change. The steepes slope is the fastest change. Now, do you know how to approximate the faster or slower change?

Answer 13

no

Answer 14

im guessing west since close contour lines have a steeper slope

Answer 15

Um, yah, I was working on a drawing to show that. Hehe.

Answer 16

okay then 5

Answer 17

And if you think about it logically, the closer line has the same drop down, 20 m, but in less length.

For 5, think about this. Each line is a distance above sea level. So sea level is 0. So how many lines past sea level are at b? and c?

Answer 18

each are 1 line

Answer 19

Nope, but close. Both are before the first line. So neither point is even 20m up.

Answer 20

ok so the answer is number 2

Answer 21

Correct.

Answer 22

ok

Answer 23

the next map i dont get

Answer 24

Well, it is the same sort of thing, just in feet not meters. They put the elevation on every line, so you don't have to do as much math to find the elevaton. The CI would be any level minus the one below it... so not 20 this time.

Answer 25

but 50 is the interval

Answer 26

Yes.

OK, so for #1 here you need to find do you know how to find 7I?

Answer 27

no
