The world's population is distributed on the earth's surface mostly either within the temperate zone or the tropics and to some extent deserts like in parts of California, the US SW, Mexico and Chile and the Middle East. The temperate zone would include such countries as Canada, the US and much of Europe parts of Russia, and China. The tropics includes most of Africa, and much of Latin America plus New Guinea, Indonesia, etc.

Stolb23 [73]

The independent variable is the amount of limestone placed inside the tanks.
The dependent variable is the ph of the water in the tanks after liming has been added.
The control group is the blood that received water, but did not receive limestone.
The amount of water could be an additional variable that was not mentioned.
A modification that would affect the results would be to place different amounts of limestone in each tank.

The dependent variable in an experiment is one that affects an outcome that can be seen. We can argue that the amount of calcium carbonate is the independent variable in the experiment since the researchers want to investigate how limestone affects acid rainwater's pH level.

A dependent variable, in turn, is one that the dependent variable affects in order to produce results. We can argue that the pH of the water is the dependent variable in the experiment above because it aims to investigate the impact of limestone on the pH of water from acid rain. The group that is not given the experimental factor is known as the control group. We can refer to the water group that did not receive any limestone as the control group as the effect of the amount of limestone on the pH change is being investigated.

Since more water can dilute the limestone by altering its impact on the water's pH, the amount of water in each blood is a variable that was not discussed but that could change the outcomes. Placing various amounts of limestone in each tank could change the outcomes and result in completely different outcomes.

The complete question is:

Scientists are interested in investigating how limestone can be used to remediate the effects of acid rain. They collect

water from a lake that has recently been exposed to acid rain. They divide the water into 10 different tanks and add

different amounts of limestone to nine of the tanks. No limestone is added to one of the tanks. The pH of the water in the

tanks is measured before the limestone is added and once every hour for 24 hours.

(f) Identify the independent variable in this investigation.

(g) Identify the dependent variable in this investigation.

(h) Identify the control group in this investigation.

(i) Describe one additional variable that has not been mentioned that could affect the results of the investigation.

(j) Describe a modification that could be made to the investigation that would affect the results.
