Bedrock
includes all of the weathered material and is very rocky.
�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:
Coal
Scoria
Gneiss
***You can see lots of different
minerals in some rocks
Minerals are
individual crystals
of all the same stuff
Rocks are
combinations
of minerals
Examples:
***Notice how each is one single type of crystal!
Gold miner panning for gold.
Gold prices are always changing, but at the time gold was $1250 an ounce(about the size of a quarter).
Desert Rose-Formed by precipitation in arid desert regions containing trapped sand particles. Usually, gypsum mineral but barite, celestine, and other minerals can form Desert Rose groups, too.
Bornite
Peacock Ore
Flint-Ohio’s gemstone
Ohio is a leading state in production of limestone, which has a wide variety of uses. Limestone is a good construction material, used as crushed stone in concrete, asphalt, and in making cement. Another important use of limestone is as an agricultural fertilizer referred to as aglime. Limestone is also used in products such as toothpaste, lipstick, carpet, chalk, porcelain, vinyl, paper, hair mousse, and fiberglass.
Sulfur
Fluorite
Calcite
Clay
Ohio is one of the leading states in the production of clay and shale. Much of the clay mined is used as liners for landfills and ponds.
Shale
Shale is a very fine-grained sedimentary rock which is made up mostly of clay.. Leaves and other plant remains occur as thin fossils in some shale. Shale is an important mineral resource in Ohio and has the same uses as clay.
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.
