Fluorite can scratch a copper coin but cannot be scratched by a copper coin.
This is because according to Mohs scale of hardness, fluorite has a hardness of four. Copper has a hardness of three. Therefore fluorite is a harder mineral than copper and will scratch copper but it will not be scratched by copper.
Mohs based his scale on the fact that some minerals could scratch others. If one mineral could scratch another but could not be scratched by it, he reasoned that it must be harder.
The limbic system of the brain gets stimulated when an individual experiences fear and pleasure.
The limbic system is a part of our brain which is responsible for the regulation of our emotional and behavioral responses, especially the ones we need for our survival. The structures of the limbic system are embedded deep in the brain. The two major structures of the limbic system include the hippocampus and the amygdala. The hippocampus helps us associate emotions and senses with different memories. The amygdala plays a pivotal role in managing our strong emotions like aggression, fear and pleasure. It also helps us in making new memories.

The process known as differentiation
It has been estimated that ‘slash and burn’ agriculture is
used by up to 500 million people worldwide. The term describes the practice of
cutting and/or burning of natural vegetation for conversion into agricultural
fields. Besides the disastrous implications for forest ecosystems, the practice
can impact the atmosphere in two main ways if burning is implemented. Firstly
by causing air pollution from the smoke, and secondly by increasing carbon
dioxide in the atmosphere, which is a greenhouse gas and a driver of climate
change. Living trees also remove carbon dioxide from the atmosphere during
photosynthesis, and the process of ‘slash and burn’ effectively removes their
carbon capturing contributions to ameliorating climate change.
