A Riddle: We Move, Together

Science fanatics will swiftly guess this riddle just by reading the title scribbled through a poem. So I wanna challenge you all to crack the riddle behind this prose of mine. Have fun!

Our planet is one-of-a-kind,

But you know what's the best thing about it?

It's the things that are working behind,

It's the things made by an infinite mind.

And fortunately we are one of those things,

Others don't see our worth but we play a role in geologic happenings,

We are not only plates that everyone used for eating,

But we are plates that covered the entire earth and made up its being.

We trapped carbon dioxide to make our planet habitable,

But as sources of earthquakes and volcanoes in dangers we are also capable,

Yet if crashed we make mountains, rift valleys and ridges,

Which don't only contribute beauty but likewise safeties.

We don't merely create motions we also define life,

We are able to making the earth vibrant that other planets may strife,

Even oceans may be barren without us driving the creation of costlines,

Seafloor may be frigid if not us getting subducted depraving life's signs.

You see our planet works in many mysterious ways,

Who might have thought that among waters, forests and sunrays,

We as entities colliding each other also made our planet livelier?

We are plates that evolve life into complex forms and we move– together.

How was it? Have you guessed it? If so, comment it down I wanna see your answers!
