Pre-Lab Information Purpose To model and observe stream processes, including factors that affect erosion and deposition
Time Approximately 45 minutes
Question What factors affect the power of a stream or river to cause erosion?
Summary In this lab, you will use a virtual model to observe stream behavior. You will model five scenarios involving a stream, and investigate the effect of water velocity, water volume, the stream slope, and the size of sediment on sand, pebbles, and various-sized rocks in a stream.

step-by-step explanation:

worked it out i believe

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
