Form of Relief in Eastern Australia

The eastern part of Australia is characterized by diverse forms of relief. The region is known for its Great Dividing Range, which is a series of mountain ranges and plateaus that stretch along the eastern coast of the continent. The Great Dividing Range is one of the longest mountain ranges in the world, extending over 3,500 kilometers (2,175 miles) from the northeastern tip of Queensland to the southeastern corner of Victoria.

The Great Dividing Range consists of several distinct sections, including the Australian Alps in the southeastern part of the range. The Australian Alps are home to the highest peaks in mainland Australia, including Mount Kosciuszko, which stands at 2,228 meters (7,310 feet) above sea level.

In addition to the Great Dividing Range, the eastern part of Australia is also characterized by coastal plains, river valleys, and plateaus. The coastal plains are relatively flat areas that extend along the eastern coast, while the river valleys are formed by the numerous rivers that flow from the mountains to the coast. The plateaus, such as the Atherton Tablelands in Queensland, are elevated areas of relatively flat land that are often surrounded by steep slopes.

Form of Relief in Southern Eurasia

The southern part of Eurasia, which includes countries like India, China, and Southeast Asian nations, is characterized by a diverse range of relief features.

One significant feature in the region is the Himalayan mountain range, which stretches across several countries, including India, Nepal, Bhutan, and China. The Himalayas are the highest mountain range in the world and are home to several of the highest peaks, including Mount Everest, which stands at 8,848 meters (29,029 feet) above sea level.

Apart from the Himalayas, the southern part of Eurasia also includes other mountain ranges, such as the Western Ghats in India and the Kunlun Mountains in China. These mountain ranges contribute to the diverse relief of the region, with their peaks, valleys, and plateaus.

The southern part of Eurasia also includes river systems like the Ganges-Brahmaputra and the Mekong, which have shaped the landscape over millions of years. These rivers have created fertile plains and deltas, such as the Ganges Delta in Bangladesh and the Mekong Delta in Vietnam, which are important agricultural regions.

Formation of Relief Features

The formation of relief features in both the eastern part of Australia and the southern part of Eurasia can be attributed to various geological processes over millions of years.

In the case of the Great Dividing Range in Australia, its formation can be traced back to the tectonic activity that occurred during the breakup of the supercontinent Gondwana. Around 180 million years ago, the eastern part of Australia began to separate from Antarctica, resulting in the uplift of the land and the formation of the mountain range. Subsequent erosion by wind, water, and ice further shaped the range into its current form.

Similarly, the formation of the Himalayas in southern Eurasia is also attributed to tectonic activity. The collision between the Indian and Eurasian tectonic plates, which began around 50 million years ago, resulted in the uplift of the land and the formation of the Himalayas. The ongoing collision continues to push the mountains higher, making them one of the most geologically active regions on Earth.

Other relief features, such as river valleys and coastal plains, are primarily shaped by erosion processes. Rivers carve out valleys over time, while coastal plains are formed by the deposition of sediments carried by rivers and ocean currents.

In summary, the diverse relief features in the eastern part of Australia and the southern part of Eurasia are the result of tectonic activity, erosion, and deposition processes that have occurred over millions of years. These processes have shaped the landscapes we see today, including mountain ranges, plateaus, river valleys, and coastal plains.
