1. Glacial till
2. Residuum
3. Glacial erratic
4. Glacial outwash
5. Loess
6. Alluvial
7. Lacusterine
8. Colluvium
9. Organic

Question 2

FITB: Glacial-related parent materials are ___ influenced with no rocks present

Answer 2

Ice

Question 3

T/F: Glacial till is sorted

Answer 3

False; it is randomly dispersed with low sorting capabilities

Question 4

FITB: Glacial till dispersion acts like a ________ belt

Answer 4

Conveyor

Question 5

T/F: Glacial till is carried by ice in no particular organization

Answer 5

True

Question 6

FITB: The parent material known as Glacial erratic has giant _______ placed in random places

Answer 6

Rocks

Question 7

FITB: Glacial outwash is transported by ______ that comes from the ______ of a glacier

Answer 7

1. Water
2. Inside

Question 8

T/F: Glacial outwash has high velocity (high energy)

Answer 8

True

Question 9

T/F: Glacial outwash has sorted, tight spaces with different soil particles spread out over a large area

Answer 9

True

Question 10

Regarding Glacial outwash, how does energy change in comparison to when it is closer to the glacier versus farther away?

Answer 10

The closer it is to the inside of the glacier, the higher the velocity and energy that will be powered. As it gets further away, the energy level lowers due to spreading out.
