yes the topic will most likely change to rivers next year but we shouldnt need to worry about that now

The B and C rules are the same.

because I just started this event this year.
Check the Dynamic Planet Wiki, it's one of the best resources. You should always try to go to the wiki to start your events, and then if you still have a question then do so.

Are Dynamic Planet test questions in the 2010 test packet?

the easiest place to look for tests and questions is on the Test Exchange

i do not have any idea if the test packet contains questions if may but i am not sure

Just to clarify: Normal and reverse faults are both types of dip-slip faults, correct? And transform faults are a kind of strike-slip fault, right?

Correct.

Normal faults are when the hanging wall slides downward in relation to the footwall. Reverse faults are when the hanging wall slides upward in relation to the footwall. The easy way to remember is that gravity normally pulls things down, so the hanging wall sliding upward would be the reverse of what normally happens.

And there are two kinds of strike-slip faults: left lateral and right lateral. Basically, the way to tell the difference is to pretend you're standing on one side (either one, it's gonna work out the same). If you look at the other side, you'll see that the fault shifted either to the left or the right. If it shifted to the right, it's right lateral, if it shifted to the left, it's left lateral.

Thanks, gneiss. I couldn't get a clear answer from googling it (though that might be because of my short attention span.)

So, wait, if you're standing on one plate and the other plate moved to your left, that would be a sinistral/left-lateral strike-slip, and if it moved to your right, that would be a dextral/right-lateral strike-slip. Am I right or am I confused?

Basically.
Here, pretend there's a river that passes through a fault-zone, and a strike slip fault occurs.You're on one side of the fault after it happens.
Looking straight ahead to the other side, you'll see that the river has been split in two (due to the faulting). If the river is to the left of the river on your side, it's left-lateral. If it's to the right of the river on your side, it's right-lateral.
Does that make sense? my geology book has a good picture of it.

Also, for the dip-slip faults, do you know how to determine which is the hanging wall? Cause that confused me for a bit until i studied it again in college.

Huh? I have no idea what you're talking about, so an explanation would be very nice. I appreciate all the help. Thank you so much.
