It just goes with time. At first, I used the preview function a lot.

Yep.

1) Drumlin= depositional landforms, Roche Moutonnee= erosional landforms. 2) Drumlin= smooth surfaces both up and downstreams, Roche Moutonnee= smooth surface upstream only. 3) Drumlin is less erosional resistant than Roche Moutonnee
Assuming that's right^^, name a consequence of Neoproterozoic snowball Earth.

EDIT:Ok, yeah, I give up on the hide function. It doesn't like me for some reason...
EDIT2: Yayyy!! It worked!!

Ya gotta put a pipe "|" symbol after the title and before the hidden text.
It would warm the Earth due to the severe increase in greenhouse gasses? I'm not sure of this one.

Yeah, that works. Your turn! (And, thank you for the tip!! It might be helpful for me to learn how to use these functions :lol: )

No problem.

1. Where is the majority of the Earth's glacial ice located?
2. What percentage of Earth's glacial ice is located there?

Define mass-balance. What does it mean when it is positive? Negative?

Mass balance is the difference between accumulation and ablation. If a glacier loses more ice than it receives, it will be in negative mass balance and will recede. Glaciers gaining more mass than they lose will be in positive mass balance and will advance.
