Natural resources
Conventional metals and composite materials for most parts. The column for example is a steel fabrication. The alternators use rare-earth alloy permanent magnets, with the corollary that their raw materials are costly and found in only a few locations on Earth.
The adjective of "found" is found, as in "He used found materials for his collage."
Satellites and light, mostly. Ozone measurements at other places on Earth, places with people, use different materials.
ROCKS USED FROM THE EARTH'S CRUST We get lots of different types of rock from the earth's crust, such as gems building material and ores. Ores such as lead gold and manganese are used to make coins. Gems, for instance diamonds, rubies and sapphires, can be carved and used in rings necklaces and earrings. Carbon fuels like coal peat and oil are flammable materials from the earth's crust. There are different types of rucks used from the earth's core for example brick, sandstone and limestone are used for building houses. Quartz is used for making clocks and chalk is used for writing. Posted by Kieran FitzGerald Edinburgh 1M1 We also get gravel and granite from the Earth's crust. Granite is used for countertops in kitchens, bathrooms, etc. We dig and mine gravel. Gravel is used for driveways and in some parking lots. It looks like little pieces of rock.
Stone, brick, tamped earth, wood, and other materials
The things found on Earth that are used by people are referred to as resources. These can include natural resources such as water, minerals, and forests, as well as human-made resources like infrastructure and technology. Resources are essential for supporting human life and enabling economic activities.
