Answer:

1.) The geography of Australia encompasses a wide variety of biogeographic regions being the world's smallest continent, while comprising the territory of the sixth-largest country in the world. The population of Australia is concentrated along the eastern and south-eastern coasts. The geography of the continent is extremely diverse, ranging from the snow-capped mountains of the Australian Alps and Tasmania to large deserts, tropical and temperate forests, grasslands, heathlands and woodlands.

Mostly desert or semi-arid, south-east and south-west corners: temperate, north: tropical climate, varied between tropical rainforests, grasslands, part desert, mountainous areas: subantarctic tundra

Terrain

mostly low plateau with deserts, rangelands and a fertile plain in the southeast; mountain ranges in the east and south-east.

Natural resources

minerals, coal, and timber

Natural hazards

Cyclones along the northern coasts, severe thunderstorms, droughts, occasional floods, heat waves, and frequent bushfires

Exclusive economic zone

8,148,250 km2 (3,146,060 sq mi)

2.) The Precambrian western core area, known geologically as a shield or craton, is subdivided by long, straight (or only slightly bowed) fractures called lineaments. Those fractures, most obvious in the north and west, delineate prominent rectangular or rhomboidal blocks, some of which have been raised to form uplands; others have been depressed to form lowlands or topographic basins. The lineaments display strong northwest-southeast and northeast-southwest trends in the northern, northwestern, and southeastern parts of the shield, but east-west alignments are prominent in the centre, and major structural lines are more nearly longitudinal in the west and southwest. In all areas, however, trends other than those that are locally dominant .

In the far southwest, the Darling Range forms an upfaulted block underlain mainly by granite but capped by laterite, a reddish, iron-rich product of weathering rock. The Gawler block, in the southeast, is complex. There are crystalline and sandstone uplands in the east, sandstone plateaus in the northeast, and, in the centre and north, the rounded Gawler Ranges built of Precambrian volcanic rocks (those older than 541 million years). Much of Eyre Peninsula is occupied by a rolling plain traversed by fixed sand dunes, but in the northwest numerous low isolated granite rocks of spectacular appearance, called inselbergs, stand above the plain. They epitomize the isolated ranges and hills widely developed in the northwest of South Australia, in the Musgrave, Everard, Birksgate, Mann, and Tomkinson ranges.

3.) When discussing mineral formations in caves, we often talk about stalactites and stalagmites. A stalactite is an icicle-shaped formation that hangs from the ceiling of a cave and is produced by precipitation of minerals from water dripping through the cave ceiling. Most stalactites have pointed tips. A stalagmite is an upward-growing mound of mineral deposits that have precipitated from water dripping onto the floor of a cave. Most stalagmites have rounded or flattened tips.

There are many other types of mineral formations found in caves. Some deposits are named based on their appearances, such as a showerhead, which is a hollow cone-shaped formation, or a conulite, which is a “splash cup” that forms when water dripping rapidly through the cave ceiling flings aside loose particles on the cave floor. And the list goes on.

Some caves are fully submerged, underwater. Studying underwater caves, such as those in Bermuda, can give us clues about how climate and sea level have changed over time. This knowledge can, in turn, help us better understand and respond to current climate and sea level fluctuations.
