An environmental change is occurring due to continents shifting and moving to different parts of the earth’s surface is a long term change due to tectonic plates movements. if this happends for the continously then there will be different sesonal changes .
There will be more acid particles to interact with the limestone at higher concentrations hence the rate of reaction increases.
The question is incomplete but I will try to help you the much I can. If you have carried out the experiment properly, you will notice that the rate of reaction increases as the concentration of the acid increases.
This is because, if the amount of limestone is held constant and the concentration of acid is increased, there will be more acid particles to interact with the limestone at higher concentrations hence the reaction proceeds faster.

Chemical factors: This is due to internal stimuli. Changes in the blood such as decrease in O2, increase in CO2 and decrease in PH cause impulse in the carotid artery which stimulates the respiratory centers in the medulla and cause breathing.
Mechanical factors: also called external stimuli. Compression of the fetal chest during delivery forces small amount of lung fluid out of the lungs. This increase in pressure in the chest draws air into the lungs.
The answer is groundwater.
Luke can use this information to sort the photos into four batches excluding the time period when it is not possible for all participants to be in the photo.
<h3>How are fossils dated?</h3>
The process of dating fossils is done by analyzing the sedimentary rocks that are formed around the animal for thousands of years, an analysis is also made of the atoms of the fossil of the animal, to give a certain accuracy to the research data.
With this information, we can conclude that Luke can use this information to sort the photos into four batches excluding the time period when it is not possible for all participants to be in the photo.
