Northeast Coast of Australia Lithograph Answers Why are Mackay and the surrounding agriculture here? The city and its surrounding farms are located here because of the limitations of the Connors Range surrounding them. The Connors sandwich the developed region between the mountains and the ocean. The presence of the river was probably an important factor in the initial settlement of the area. Most of Australia's population lives within 20 miles of the ocean. Why does the water appear to be different colors? The color of the water can indicate depth (eg, darker blues in deeper areas) or the presence of particles suspended in the water. Lighter, greener areas (especially those with swirls and eddy patterns) indicate the flow and mixing of the water masses. The suspended materials here may be either sediment and runoff from the area's rivers, or, in this case, possibly salt precipitated out by high concentration or temperature. Why are the agricultural fields arranged as they are? The fields are arranged to take advantage of most of the flat, usable land. Note the way the surround, but do not cover, the outlying hills.
