How do tsunamis form?

Tsunamis aren't just big waves; they're actually giant pulses of energy movin' through the whole ocean! It all starts deep down where these massive Seafloor Plates suddenly snap or shift during an earthquake, actin' like a giant piston pushin' upward. Because that movement is so powerful, it lifts the entire Water Column—that's every single drop of water from the bottom to the surface—all at once! This creates Deep Waves that race across the open ocean incredibly fast, sometimes as quick as a JET PLANE, even though they look small on the surface. But check this out: when that energy hits Shallow Water near the coast, the bottom of the wave drags against the ground, causin' it to slow down and pile up. All that speed turns into height, transformin' into a Tsunami Wave that grows TALLER and TALLER before it finally hits the shore. Nature's physics are pretty wild! Tiny Concepts.
