What is a desert?
What are the 2 types of glaciers?
Alpine glaciers and Ice Sheets
What are examples of an ice sheet?
Antarctica and Greenland.
What are the four Earth systems?

What is the definition of a dune?

Per the text: "The elevation above which not all snow melts is called the _____?"

Name the phases of the moon in order.
New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.
Mudflow and Lahar.
What are 2 ways that wind erosion leading to desert particles transporting?
1: Deflation
Wind lifts/removes loose material
2: Abrasion
Wind causes grinding and erosion of rocks through water, ice, and/or gravity.
What is an alpine glacier?
These form in a mountainous area where accumulation of ice is at higher elevations that then flows down through narrow valleys.
What is an ice sheet?

What are drumlins and eskers?
Drumlins: With ice sheets moving over moraines, the ice that moves can sometimes mold material into elongated hills.
Eskers: A long and winding ridge of layered sediments.
What are the percentages that make up soil?
What are 3 variables that can change how mass movement occurs?
1: The amount of water in loose materials w/slopes
2: Presence/how much vegetation is on a surface
3: Earthquakes: they speed up the potential for more mass movement.
