Interactive rock cycle activity: Press the button to play.
The use of rocks:
-Building materials: cement (limestone and clay), concrete (cement, water, sand and gravel), glass (sand),
-Ornamental rocks: marble, granite, slate and basalt
-Source of fossil fuels: coal and oil
-Source of minerals for technological use: silicon from rocks rich in quartz, aluminium from bauxite.
Extraction of minerals and rocks:
Mineral of interest: ore; the other rocks are called gangue.
-Superficial extraction: marble, gravel, etc
-Subterranean extractions: coal
Minerals and rocks laboratory:
You will owrk in groups to observe the minerals and rocks in order to identify them. You will fill a table in and you will use the table during the exam. Find here the table and the roles of the group members.
