Each minute and hour of the day.

not often, atmost one a day
The US has about 50 earthquakes every day.
Adenosine is a chemical in the body that may contribute to fatigue. It accumulates in the brain throughout the day and can promote sleepiness. If players are experiencing fatigue on their first day in a new city, it could be due to disrupted sleep patterns, increased stress, or changes in daily routine, which could impact adenosine levels and lead to fatigue.
introduction
Chemical changes improve the quality of life in many ways. Medicines created from combining chemicals save lives every day, for example. Cooking is a series of chemical changes, for another example.
Cooking is the most important example; also burning of fuels in cars, combustion of fuels for heating, preparation of beers and wines, etc.
Each minute and hour of the day.
There are many products that we use every day that are developed with a chemical reaction. Some examples of daily chemical reactions are; medication, the use of a propane grill and breathing.
This site changes billions of times a day. Just go to Recent Site Activity and watch how many changes there are. If you mean site-wide updates, these happen every couple of months.
Yes they do if you ask how many earthquakes happen each day.
Buildings change overtime due to many factors. They change due to chemical weathering outside. The weather changes the outside of the building. The owner changes the buildings as well to fit with the modern day looks and attract people.
Weathering is the gradual erosion of rock and soil from rain and wind, and to a lesser extent from the chemical changes induced by solar ultraviolet exposure, and the diurnal thermal expansion and contraction, the day/night mechanical wear from heating and cooling. It occurs constantly.
I think about 100 in the USA a day...
24,000 on Saint Patricks Day
About 100 to 1,000
