The top half of the glacier moves faster than the bottom, presumably because of friction. The sides also flow slower than the middle, also because of friction. Ice in the accumulation zone flows downward relative to the surface of the glacier, from accumulated snowfall, while ice in the ablation zone flows upward.

The flowing ice in the middle of the glacier moves faster than the base, which grinds slowly along its rocky bed.

When the lower ice of a glacier flows, it moves the upper ice along with it, so although it might seem from the stress patterns (red numbers and red arrows) shown in Figure 16.13 that the lower part moves the most, in fact while the lower part deforms (and flows) and the upper part doesn’t deform at all, the upper part …

Evidence of the flowing ice can be found in glacier’s heavily crevassed surface. Glaciers move by a combination of (1) deformation of the ice itself and (2) motion at the glacier base. At the bottom of the glacier, ice can slide over bedrock or shear subglacial sediments.

Other molecules of water vapor bind to the crystal, forming the familiar six-sided snowflake. As time passes, subsequent snowfalls cover the snowflake. The weight of the overlying layers compacts the snow surrounding the flake, causing these flakes to nestle closer to one another.

By picking up soil and rocks and depositing them in new locations. Which of the following is a sign that a valley glacier has moved through an area? Where in Africa could you find a valley glacier? On a frozen mountain peak.

As a glacier retreats, the ice literally melts away from underneath the moraines, so they leave long, narrow ridges that show where the glacier used to be. Glaciers do not always leave moraines behind, however, because sometimes the glacier’s own meltwater washes the material away.

Cirques are bowl-shaped, amphitheater-like depressions that glaciers carve into mountains and valley sidewalls at high elevations. Often, the glaciers flow up and over the lip of the cirque as gravity drives them downslope.

An arête is a thin, crest of rock left after two adjacent glaciers have worn a steep ridge into the rock. Cirques are concave, circular basins carved by the base of a glacier as it erodes the landscape.

An arête is formed by the movement of a glacier. Glaciers move slowly and carry rocks and sand that can reshape the land. When a glacier passes both sides of a mountain top or other rock formation, it can wear the rock and create a sharp edge. The sides of an arête are usually very steep, with jagged edges.

When used in the context of the anatomy of muscle structures, the word striations refers to the stripe-like visual features found in skeletal muscle. These visual features consist of alternating light and dark striations that can be observed using just a simple light microscope.

example. .. she is just a monstrosity meaning she is a mess…the building is just a monstrosity, meaning it is an ugly big building the Internet seems to have made this word shorter is what I’m understanding.
