* Everything on Earth ultimately came from the Earth itself. Even animals and plants are made of elements that originated in the Earth's core or were brought here from space.
That being said, here are some substances formed in the Earth that are not directly from animals or plants:
* Minerals: These are naturally occurring solid substances with a definite chemical composition and crystalline structure. Examples include quartz, diamond, gold, and salt.
* Rocks: Rocks are made up of one or more minerals. They can be formed through various processes like volcanic activity, weathering, and erosion. Examples include granite, limestone, and sandstone.
* Fossil Fuels: These are formed over millions of years from the remains of ancient plants and animals, but they're not technically directly from the organisms themselves. They're transformed versions of organic matter. Examples include coal, oil, and natural gas.
So, the answer depends on how you define "formed in the Earth". If you're looking for something that's not directly from living things, then minerals, rocks, and fossil fuels are good examples.
