A. flat land
B. steep slopes
Step-by-step explanation:
Oceania is an island continent of the Earth made up of the continental shelf of Australia, the islands of New Guinea, New Zealand and the coral and volcanic archipelagos of Melanesia, Micronesia and Polynesia. Historically it was considered that Insulindia was also part of Oceania. All these islands are distributed by the Pacific Ocean. With an extension of 9 008 458 km², it is the smallest continent on planet Earth.
The territories of Oceania extend from Southeast Asia through the Pacific Ocean to America. With its extension of 9 008 458 km² it is the smallest continent in the world. It is bathed by the Indian and Pacific oceans, with a total of 25,760 km of coastline and has the second largest island in the world, New Guinea, with 785,773 km². The climate is strongly influenced by ocean currents, including El Niño, which causes periodic droughts, and the low-pressure tropical seasonal system, which produces cyclones in northern Australia.
The desert or semi-arid region is the largest: 40% of its territory is covered by sand dunes. Oceania is the driest, flattest continent, with the oldest and least fertile lands. Interestingly, the highest mountain on the continent, Mount Jaya (4884 m), is not found in Australia, but is located on the island of New Guinea, belonging to Indonesia. Mount Kosciuszko, with 2228 m, is the main elevation of continental Oceania.
