Question

The lowest point of Australia is____________.
A) Caspian Lake
B) Eyre Lake
C) Valdes Peninsula
D) Death Valley

Answer 1

Hint: Australia’s lowest point has an elevation of about 50 feet below sea level. It is a great salt lake situated in central South Australia, with a total area of around 11,088 square km.

Complete answer:
Sea level is defined as the sea’s surface level at around the point where it meets the land halfway between the mean high and low tides. It is not constant and is subject to changes due to fluctuating climatic conditions and also the difference in localities.

The term ‘Mean sea level (MSL)' was introduced to refer to the measure of the average height of the sea’s surface over a long period. The measurement is used as the basis to determine elevations and depths of the geographical surfaces present on the Earth.

Now let us look into the given options:
Option A. Caspian Lake: The Caspian Sea is considered as the lowest point of Europe. This slightly-saline lake has an elevation of about 92 feet below sea level. Hence, it is not the correct option.
Option B. Eyre Lake: The dry bed of Lake Eyre, South Australia, is considered as the lowest point of Australia. It is 50 feet below sea level. Hence, it is the correct option.
Option C. Valdes Peninsula: It is the lowest point of South America with an elevation of about 131 feet below sea level. Hence, it is not the correct option.
Option D. Death Valley: It is considered as the lowest point of North America with an elevation of about 282 feet below sea level. Hence, it is not the correct option.

Thus, the correct answer is Option B. Eyre Lake.

Note: ustralia is the world’s lowest continent with an average elevation of only 330 metres. Mount Kosciuszko, New South Wales, is the highest point on the Australian mainland with an elevation of about 2228 metres above sea level
