Question

1. use the following elevation profile to answer the question.

what is the change in elevation from the highest point of the great victoria desert to the highest point of the great dividing range?

a. about 500 feet
b. about 1,500 feet
c. about 2,500 feet
d. about 5,000 feet

Explanation:

Identify the elevation of the Great Victoria Desert

We analyze the provided elevation profile of Australia. The question asks for the change in elevation from the highest point of the Great Victoria Desert to the highest point of the Great Dividing Range. Looking at the profile, the region labeled "Great Victoria Desert" lies in the central-western portion. The highest point in this desert section reaches just above the \(1,000\text{ feet}\) line, at approximately \(1,200\text{ feet}\) to \(1,300\text{ feet}\).

Identify the elevation of the Great Dividing Range

Next, we locate the "Great Dividing Range" on the right side of the profile. The peak of this range rises significantly higher, reaching just below the \(3,000\text{ feet}\) line. This highest point is approximately \(2,700\text{ feet}\) to \(2,800\text{ feet}\).

Calculate the change in elevation

Using our knowledge of Physical Geography of Oceania and topographic profiles, we find the difference between these two elevations:

$$ \text{Elevation Change} \approx 2,750\text{ feet} - 1,250\text{ feet} = 1,500\text{ feet} $$

This matches option B.

Answer:

• A. about 500 feet
• B. about 1,500 feet (Correct answer)
• C. about 2,500 feet
• D. about 5,000 feet
