The core is the densest layer.
layers of lava pile on top of each other, making many layers of it.
Yes because like sedimentary rocks they stacked on top of each other

Layers of sediment are piled on top of each other, and the top layers compress the lower layers into rock.
The crust is the least dense of the Earth's layers. Each layer is denser than the layer above it. This is very logical, since lighter layers float on top of heavier layers.
they are called layers
The core is the densest layer.
The core is the densest layer.
The mantle is the 2nd hottest
1- why should alternate layers be laid at 90 degrees to each other?
wet ice causes ice layers to slide over each other
Because there different kind of layers and they each are totally different from each other!
There is no interaction of ozone layer with other layers. All of them are independent of each other.
If both layers are water, then make one of them warmer than the other one.
