Question

glaciers

1. glacier = a slowly moving ____ of __ formed by the accumulation and compaction of __ on mountains or near the ____
2. as glaciers move downhill, they ______ the base and sides of their channel

• create u - shaped ______!

1. at the bottom of glaciers, the snowmelt often makes ____ and then ____ streams

• braided streams form because most of the sediment is coarse ______

glacier basic terms

1. zone of accumulation = where ______ / ice is building up
2. zone of ______ = where snow / ice is

lost (from melting, calving, sublimating, etc)

1. ______ = a crack in a glacier

caused by the stress of its movement

1. ______ = bowl - shaped,

amphitheater - like depression eroded into the
head or the side of a glacier valley

1. ______ = unsorted deposits of

sediment that form from different parts of a
glacier

1. glacial ______ = several cirques from glaciers flowing in different

direction from a mountain peak leave behind a sharp sided peak

Explanation:

These questions are about glaciers, their formation, movement, and related geological features. The subfield of Natural Science that best applies is Geography (specifically glaciology, a part of physical geography) as it deals with Earth's physical features and processes like glacial activity.

Q24:

A glacier is a slowly moving mass of ice formed by the accumulation and compaction of snow on mountains or near the poles.

Q25:

As glaciers move downhill, they erode the base and sides of their channel. This erosion creates U - shaped valleys.

Q26:

At the bottom of glaciers, the snowmelt often makes ponds and then braided streams. Braided streams form because most of the sediment is coarse (like gravel or boulders).

Q27:

Zone of Accumulation = where snow/ice is building up.

Q28:

Zone of Ablation = where snow/ice is lost (from melting, calving, sublimating, etc).

Q29:

Crevasse = a crack in a glacier caused by the stress of its movement.

Q30:

Cirque = bowl - shaped, amphitheater - like depression eroded into the head or the side of a glacier valley.

Q31:

Till = unsorted deposits of sediment that form from different parts of a glacier.

Q32:

Glacial horn = several cirques from glaciers flowing in different directions from a mountain peak leave behind a sharp - sided peak.

Answer:

1. mass, ice, snow, poles
2. erode, valleys
3. ponds, braided, (gravel/boulders)
4. snow
5. Ablation
6. Crevasse
7. Cirque
8. Till
9. horn
