Bedrock

The solid layer of soil made entirely of solid rock.

Depending on your location, some bedrock is closer to the surface than others.

Rocks are made up of minerals. Minerals are within all rocks. The minerals in rocks are what makes rocks look different from other rocks.

The Earth’s crust is made up of two things:

  • Minerals and Rocks

Coal

Scoria

Gneiss

***You can see lots of different

minerals in some rocks

Minerals are

of all the same stuff

Rocks are

combinations

of minerals

Examples:

  • Galena Gold Pyrite

***Notice how each is one single type of crystal!

Nonrenewable natural resources are things that take longer than a person's lifespan to be replaced.

They don't regrow and they are not replaced or renewed. They include the fossil fuels we burn for energy (natural gas, coal, and oil). Minerals, are also nonrenewable natural resources.

Thank you Ron and Ruth Langsdon for making this presentation possible and for donating over 900 beautiful minerals from around the world. Come visit the Mercer County District Library and find your favorite mineral.
