Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. A physical change doesn’t break the bonds between atoms of a substance or form new ones. Compounds can be broken down by a chemical change. A chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. What simple substance would a compound break into? The basic elements that make it up! For example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. Which of the following is an example of a chemical change?

A
separating water into different glasses

B
breaking frozen ice cubes with a hammer

C
running an electric current through water

D
boiling water to evaporate it on a stove

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.

Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

A student at an exhibition looks at a model of Earth, as shown. The model is made using different colors to show water and land on the surface of Earth. The color green shows areas covered in land and blue shows areas covered in water. Each side of the model is shown.



The student learns that the water on Earth is stored in different forms. Water on Earth is broadly categorized into salt water and freshwater. The usability of water depends on the quantity available and its characteristics. The model shows the distribution of water on Earth in various reservoirs.

Question:The student claims there are large quantities of water immediately available for humans to drink on the surface of Earth. Is the claim given by the student correct? Use evidence from the graphs to describe why or why not.
