The correct answer is Option C) The environments of Australia and Asia are completely different, despite their relative close proximity.
The naturalist and father of zoo - geography Alfred Russel Wallace noted a distinct difference in the fauna between several islands in the Malay Archipelago (present-day Indonesia). He used these differences to delineate the boundary between the Australian and Oriental biogeographic realms. The reason behind this difference is that the environments of Australia and Asia are completely different, despite they are in a very close proximity relatively.
<h3>Why is the environment of Australia and Asia different?</h3>
The Wallace line is a boundary line drawn by British naturalist Alfred Russel Wallace on the basis of difference in fauna in the year 1859 between Asia and Australia. The reason and the root cause behind this faunal distinction is that the ancient supercontinent named Gondwana was separated entirely from other parts of the world when Pangaea broke up. The current Australia and the smaller islands were a part of Gondwana and this is why their fauna is so different from that of South - East Asia, even if they are very close together relatively.

Answer:
thick,white fur
Explanation:
Their white fur helps them blend in with the snow and ice. A polar bear has a layer of fat under its skin which helps it stay warm. It also has a thick layer of fur
Geologists can determine the actual age of features on a planet by the radiometric dating method in which the age of the rocks is calculated by the natural decay of the radioactive isotopes of elements such as carbon.
In the radiometric dating method, the radioactive minerals in rocks are used. The radioactive isotopes, which are the chemical elements, naturally break down and decay to form a new isotope.
Each radioactive element has a unique decay rate which is known. Hence, the radioactive isotopes are crucial for the geologist to compare and identify the age of the rocks and furthermore, the planet.
