The landforms in the interior of the continents and at their margins mostly differ because of the difference in geological activity.
Explanation:
The landforms that are found in the interior of the continents tend to be old. They also are mostly consisted of sedimentary and metamorphic rocks. In general the erosion is much more evident and dominant, thus the landforms also are with lower elevations when compared with the ones on the edges. This is due to the lack of geological activity as the interiors of the continents tend to be far away from the plate boundaries.
The landforms on the edges of the continents tend to be younger in general. The reason for that are the subduction zones and intense geological activity. The intense geological activity is due to the close proximity of the plate boundaries. The landforms tend to be higher in general, and volcanic arcs are also a common sight.

A. It would be the Sahara Desert.
Answer: B) Bob is using his personal knowledge of the local area to make his forecast.
Explanation:
Weather forecasting uses a series of technological instruments and human knowledge to predict changes in the weather. Instruments which may be digital measure the temperature, wind directions and other atmospheric conditions. However, these measurements and observations can sometimes be confusing and require knowledge of the local weather to be interpreted correctly. This is what Bob has done here.
