Earth Breaker is a last ditch attack utilized by Frieza in order to detonate the planet he is on.
Frieza presses his palms into the earth of the planet he is on and then detonates the entire planet with his ki. Causing the ground to rupture and beams of fire to spew from the Earth, soon resulting in the planet being destroyed.
In Dragon Ball Z: Resurrection ‘F’, after falling out of his Golden Form state and realizing that there was no way for him to defeat Super Saiyan Blue Vegeta, Frieza utilized this technique to destroy the Earth, killing Vegeta and everyone else on Earth, including Trunks and Goten except those who were around Whis during the attack. However, Whis was able to rewind time to the moment just before Frieza uses the technique, allowing Goku to finish him off first.
