Well, it's a little pointless if you're going to quote the original post like that, isn't it?

[greenmilktea]

am I allowed to begin a new question if nothing is being asked right now? sorry if not!

1. How do crag and tail formations differ from rôches moutonnées?
2. What is an ice cap? What are the requirements for an ice cap to be considered an ice sheet?
3. What is the most common type of crevasse? Describe it!

1. Rôche moutonnées are usually smaller.

2. A dome-shaped layer of ice. must be over 50,000 square km to be considered an ice sheet.

3. Transverse: they open across a glacier and form where valleys become steeper.

Looks good. Your turn!

List the Milankovitch cycles and describe their effects on Earth's climate.

[JoeyC]

1.) Eccentricity; affects the magnitude of other cycles, bringing the Earth closer to or farther away from the Sun at certain points.
2.) Precision; the Earth's axis spins so that eventually different sides of the Earth will be tilted at the Sun; affects seasons.
3.) Obliquity; the Earth's axis's tilt fluctuates ~3* so that the [seasons become more or less drastic

yep, your turn

State the difference between epochs, ages, and other geological measures of time.

Ages are subdivisions of epochs, which are subdivisions of periods. Need more?

Edit: Forgot to hide it...

Could be more specific, but go on ahead!
