Question 1: Why do we have wisdom teeth?
Question 2: When a substance changes from a solid to a gas without passing through the liquid phase, what is this process called?
Sublimation can occur under certain temperature and pressure conditions. Famous examples of substances that can go through sublimation are dry ice (solid carbon dioxide) and naphthalene (mothballs).
Question 3: What is the force that holds atomic nuclei together?
The strong nuclear force also known as the strong force or strong interaction, is one of the four fundamental forces of nature. It is about 100 times stronger than the electromagnetic force, yet acts at very short range, typically only within atomic nuclei.
Question 4: What causes an earthquake?
Earthquakes are caused by the release of energy in the Earth's lithosphere due to movements along fault lines, where tectonic plates meet. This sudden release of energy causes the seismic waves that make the ground shake.

The surface area of an average adult human's lungs is approximately equal to the size of a tennis court. The large surface area is necessary for efficient gas exchange between the lungs and the blood.
Question 7: In botany, what is the process by which green plants convert sunlight into chemical energy?
Photosynthesis involves the uptake of carbon dioxide and release of oxygen. It is an essential process that not only helps plants grow but also maintains Earth's oxygen levels for breathing and facilitates the carbon cycle.
Question 8: Who is known as the "Father of Modern Geology"?
James Hutton, a Scottish geologist, played a key role in establishing the modern understanding of geology with his contributions to the Theory of the Earth, uniformitarianism, and the concept of deep time.
