Difference Between Islands and Continents
There is a difference between islands and continents in terms of geology. Continents sit on continental lithosphere which is part of tectonic plates floating high on Earth's molten mantle. Oceanic crust is also part of tectonic plates, but it is denser than continental lithosphere, so it floats low on the mantle. Islands are either extensions of the oceanic crust (e.g. volcanic islands) or geologically they are part of some continent sitting on continental lithosphere (e.g. Greenland). This holds true for Australia, which sits on its own continental lithosphere and tectonic plate.

“The difference between guilt and shame is very clear—in theory. We feel guilty for what we do. We feel shame for what we are. A person feels guilt because he did something wrong. A person feels shame because he is something wrong. We may feel guilty because we lied to our mother. We may feel shame because we are not the person our mother wanted us to be.”
—Lewis B. Smedes, U.S. psychologist, educator. Shame and Grace: Healing the Shame We Don’t Deserve, ch. 2, Harper (1993)
“What are the islands to me
if you are lost
what is Naxos, Tinos, Andros,
and Delos, the clasp
of the white necklace?”
—Hilda Doolittle (1886–1961)
“Nay, be a Columbus to whole new continents and worlds within you, opening new channels, not of trade, but of thought.”
—Henry David Thoreau (1817–1862)
