Rocks can pose several problems to humans, including natural hazards like landslides and rockfalls, which can lead to property damage and loss of life. They can also disrupt construction activities, particularly when hard rock formations require extensive blasting or drilling. Additionally, certain types of rocks can contain harmful minerals, such as asbestos, which can pose health risks if disturbed. Finally, rocks can obstruct transportation routes, making travel and logistics more challenging.
I. Man gets information about earth from rocks. II. Man gets metals from rocks and makes them into jewelry. III. Man uses rocks for building roads and bridges.
Yes, man-made rocks, such as concrete or engineered stone, can be considered rocks, but they differ from natural rocks in their formation process. While natural rocks are formed through geological processes over time, man-made rocks are created by humans using various materials and methods. They can serve similar purposes in construction and design but are classified differently due to their origin. Ultimately, their classification as "rocks" depends on the context in which they are being discussed.

Obsidian is an igneous rock. Rocks are not man-made. Man-made substances that are similar to rock include concrete and cement.

Yes they are man made..
It wears away at rocks and monuements. :(

It is impossible to determine the exact number of rocks on Earth known to humans as new rocks are constantly being discovered and classified by geologists. However, there are estimated to be over 5,000 different types of rocks known to science.
