If the Earth were scaled down, could OP destroy it by squeezing it with their hand?

So like a Earth shaped ball made up of the same things as the Earth?

If it were at the same temperature as Earth's components it'd simply explode since the core of the Earth is well above irons boiling point and is only kept solid and liquid by the pressure. If the ball were cold then no, it'd be a rock. I suppose if the scaled down Earth model were made from roughly analogous materials (iron cored ball of lava with a very thin rock shell) then you could probably crush it quite easily... although you'd basically holding a ball of lava so you'd act quickly to finish crushing it before your hand burned off.

This is probably more in the spirit of the OPs question I think.

The core is metal, so no.
