Because it forms this way to save things lol ahaha
If it were the other way around, lakes would freeze from the bottom up, and all the fish would die in the winter.
The asthenosphere is a flowing solid. It's sort of a liquid and a solid.
Solid water, ice, is less dense than its liquid state. This is essential for aquatic life. Since ice is less dense than liquid water, it floats to the top of of the water. This insulates the water beneath the ice, allowing the water beneath the ice to remain liquid. For other substances, the solid state is more dense than the liquid state.
solid with hydrogen bonds making it less dense than its liquid form
I think oil is not a solid. It does not have definite volume.It is a Liquid.
The solid state of water is less dense than its liquid state, which is why ice floats on water. The solid state of nearly all other substances is more dense than the liquid state and sinks in the liquid state.
This depends on how dense the solid is, and how dense the liquid is.

Ice is a solid less dense than the liquid
Liquid magma is more dense than the solid material around it.
Less dense. For most substances, the solid form is more dense than the liquid form; water is a notable exception.Less dense.

In addition to water, for which the solid form (ice) is less dense than the liquid form, the element Gallium is also less dense in the liquid state. Gallium can be solid at room temperature but will melt in the hand.confirmed as solid less dense than liquid:gallium - 5.91 (solid) vs 6.095 (liquid)bismuth - 9.78 (solid) vs 10.05 (liquid)germanium - 5.323 (solid) vs 5.60 (liquid)silicon - 2.3290 (solid) vs 2.57 (liquid)water - 0.917 (solid) vs 0.998 (liquid)claimed but probably false:acetic acid - 1.266 (solid) vs 1.049 (liquid)antimony - 6.697 (solid) vs 6.53 (liquid) (this "error" is repeated in many places, inc wikipedia)Water is not always less dense in solid form. Depending on how the water crystals are formed, it may actually be more dense. Examples include HDA and VHDA.

Solid Argon is more dense than the liquid phase

Solid water, ice, is less dense than liquid water and floats on top. The solid state of other substances is more dense than the liquid state and will sink in the liquid.
solid will be settling at the bottom because liquid can not be denser than solid due to their arrangements of their molecules.
