1. How can you tell that the land reaches
very high elevations?
It is clear from the image that the area reaches high elevations
due to the distinct shadows that are cast on the mountainsides,
and is the reason why the image has a 3-dimentional look. In contrast
to the calm and smooth appearance of the water body (in squares
1D and 2D for example) the land area is more mottled in tone and
is evidently more rugged.

2. What do you
think is the dominant land cover in this area?
As the image is a natural colour image the green colour of the mountains
indicates that the dominant land cover is dense forest |

3. Can you identify evidence of
mass movement within the mountain range?
Within the forested slopes there is evidence of bare rock surface,
these non-vegetated areas are represented by pale pink tones.
However, within B4, the rocky outcrops tend to be relatively linear
in appearance and as they are orientated up and down the slope,
they are clear evidence of landslides. These features are a further
indication of the area being composed of steep slopes

4. On what facing
slopes do the majority of the snow patches occur? Why is this?
The snow patches (eg. square C3) are present on the north facing
slopes. The main reason for this is aspect. Slopes that face towards
the sun (South facing slopes) are exposed to direct insolation.
Whereas the slopes that face away from the sun (North facing slopes)
are sheltered from the direct solar rays and tend to have relatively
cooler slopes. Hence the snow and ice patches will melt sooner on
the south facing slopes. Thus the direction the slopes face (or
aspect) is the reason for the accumulation of snow. |

5. What sort of
shoreline is present in the area?
The jagged shape of the coastline indicates that the shoreline is
rocky one as opposed to a sandy one. |
|
6. What do the
white tones around the coastline represent?
The white tones around the shore represent waves breaking on the
rocky shoreline, they are particularly noticeable at the top of
the image (especially in B1). The reason for this is that this side
of the coast is likely to have been considerably more windy and
exposed at the time the image was obtained. |
