group discussion:
Are rocks and minerals closely related to our lives? Why?
Rocks and minerals are a big world
Any non-biological product may be made from ores or minerals found in ores.
The solid parts that cover the Earth's surface are called rocks. The Earth's crust is made of solid rock and is ever-changing. Igneous rocks make up about 65% of the entire Earth's crust. Sedimentary rocks are the most widely distributed on the surface of the earth's crust and contain the most abundant minerals.
There are more than 4,000 kinds of minerals on the earth, and minerals that are not found on the earth are obtained from meteorites every year. How to identify these thousands of minerals?
People also study various geological structures, landforms, and crustal history through rocks.
Rocks and minerals are important raw materials for construction, production, and life. The world is colorful, and their exploration, mining, refining, processing, and use are a big industry.
The role of rocks:
Building materials: Build stone houses, stone walls (Great Wall), stone bridges, pyramids, cement, etc.
Industrial raw materials: cement (gravel), steel (lime), various minerals extracted from ore.
Art material: marble is more commonly used
Decorative use: generally used after cutting and polishing. Commonly found on building exterior walls, walls, floors, ceilings and counters, furniture, various stone monuments, etc.
Gemstones: can be made into jewelry, including gemstones, gemstones, diamonds, emeralds and various jade.

Some minerals can also be used as traditional Chinese medicine. For example, gypsum has a heat-clearing effect, borax has a soothing and sedative effect, and borax has a heat-clearing, anti-inflammatory, detoxifying and antiseptic effect.
Due to its low thermal conductivity, asbestos can be used as thermal insulation materials, such as asbestos boards and other products.

With human activities of mining minerals, the loss of mineral resources around the world is serious. The earth's resources are limited, and excessive mining will exhaust the earth's resources. Excavation can also easily cause loose mud and rocks, trigger mudslides and cause landslides, which not only destroys the natural landscape, but also endangers people's lives and safety. What should we do in the face of dwindling mineral resources?
