Ahh oops totally blanked on that, umm so for my question...What is the Moho and where is it?
Are there other discontinuities like this one? Name them all.

Moho is the boundary between the crust and the mantle. The Lehman discontinuity is inner core/outer core; the Gutenberg discontinuity is the outer core/mantle.

What are two main factors in determining the viscosity of a magma? Also, what effect does each of them have (directly/inversely proportional)?

Temperature and composition (% silica). Temperature is inverse (hotter magma is runnier) whereas silica is direct (more silica=thicker magma).

Hey guys hope you don't mind if I get in on this.

Q: List and define three categories of mass wasting events. What is mass wasting and what are two factors that primarily contribute to its severity?
Bonus: What is a Sturztrom?

Usually the order goes like this:

A: asks question
B: answers
A: correct, your turn
B: asks question
C: answers

unless the thread has been dead for a while and you want to revive it.

You have a good question, just wait for liberalartslover to finish up their round first.

1. Fall -  freefall of detached individual pieces of any size
2. Slide - material sliding down a well defined surface as a coherent unit
3. flow - moving downslope as a viscous fluid
Mass Wasting is any event that involves movement of sediment or rock type material downslope as a group, or mass.
Speed and type of material contribute to severity.
A sturztrom is where horizontal movement is much greater than verticals (like before Mount St. Helens erupted.
The definition of mass wasting is sorta weird to answer.
