<span>Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Explanation:
Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.

Given what we know, we can confirm that since Mr. Summers has to test a hypothesis, his next step should be to design an experiment. 
<h3>Why design an Experiment?</h3>
- The next step is to design an experiment.
- This is because Mr. Summers has already made an observation and created a problem.
- He must now gather data to be analyzed. 
- In order to do this, he must first design and perform an experiment. 
Therefore, we can confirm that Mr. Summers must design an experiment given that this is the best way to gather data in order to be analyzed in the future and draw a valid conclusion.
