Did the house burn up or did it burn down?

If you are referring to what happened to the house itself, it burned down to the ground. The only remnants of the once-high building have now burned down.

If you're referring to the actual act of the burning, the flames burning the house were burning it up.

Burned down would be better in that sentence.

Burned down implies extensive damage or the house was ruined.

Burned up would implies that the house was completely incinerated; there is absolutely nothing left, not even burnt wood. Burned up would better apply to the possessions in the house. "My diploma burned up."

The house 'burned down' because the debris from the fire will settle on the ground,which is down as the sky is up.Alternatively the house could go 'up in smoke'.

Burned down.

Technically, if the structure of the house is destroyed, then the house is going to collapse towards gravity, so it's always going to be "down". The flames, however, burn upwards.

"Burn down" would be correct, but that is an interesting question. A matchstick or a piece of paper, for instance, would definitely burn up. I suppose something meant to burn and is consumed as it burns (like a candle, or a rocket, or a meteor) burns up, while something not meant to burn, but does and is ruined by it, burns down.

Burned down conveys correct sense.

well it matters.... if the fire started at the top and went down it burned down..... but if it started at the bottom it burned up get it? but if you want to get a little more advice then......then burning up is HOT!!! no windows or air conditioning so people usually use the term burning down

Burn up is usually like hot.

Burn Down is usually a fire

Use "burn down" never in English did I hear burn up.
