GEOLOGY

Detailed explanation-1: -What is left behind is a cavity in the rock where the organism or part was. This empty space is called a mold. A mold shows the original shape and surface of the organism or part. Sometimes, sand or mud fills a mold and hardens, forming a cast of the original organism or part.

Detailed explanation-2: -A mold forms when hard parts of an organism are buried in sediment, such as sand, silt, or clay. The hard parts completely dissolve over time, leaving behind a hollow area with the organism’s shape.

Detailed explanation-3: -Sometimes when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a cast fossil. The fossilized imprint is called a mold fossil.

Detailed explanation-4: -Organic waste: Waste created by or from a once-living organism. It is capable of decay and is composed of carbon compounds. Vermicomposting: Using earthworms/red wiggler worms to turn organic waste into very high quality compost.

Detailed explanation-5: -A mold is a hole left in rock after an organism’s remains break. A cast forms from the minerals that fill that hole and solidify. A mold is the depression left in the shape of the fossilized organism.
