The Earth does not absorb blood or any other substances in the way that a sponge absorbs water. This is because the Earth’s surface is primarily composed of soil, rocks, minerals, and other solid materials that do not have the capacity to absorb liquids like a porous material does.
When blood or any other liquid is spilled on the ground, it may be absorbed temporarily by any loose soil or porous materials in the immediate vicinity, but it does not get absorbed into the Earth’s core or mantle. The Earth’s surface materials, even when porous, have limitations on their ability to absorb fluids, and this absorption is typically limited to a shallow depth.
In most cases, liquids that are spilled on the ground will either evaporate, be absorbed by plants or organisms in the soil, or flow into nearby bodies of water. The Earth’s ability to absorb substances is influenced by its geology, soil composition, and the presence of vegetation, but it does not have the capacity to absorb substances like a sponge or a liquid-absorbing material might.
