The correct answer for the phenomenon described in the question is option 2 - greenhouse effect.

To understand this, let`s dissect each option:

Option 1 - ozone depletion: Ozone depletion refers to the reduction of the protective ozone layer in the Earth`s atmosphere, primarily caused by human activities like the release of chlorofluorocarbons (CFCs). This phenomenon is unrelated to the heat trapped inside a car.

Option 3 - solar effect: The solar effect generally refers to the impact of the sun`s energy on Earth`s climate, which includes factors like sunlight intensity, solar radiation, and solar flares. While the sun`s heat can contribute to the heat trapped inside a car, it does not specifically explain the mechanism by which heat is trapped in this scenario.

Option 4 - cosmic ray impingement: Cosmic rays are high-energy particles originating from outer space. They have minimal impact on the heat trapped inside a car, making this option unrelated to the phenomenon described.

The greenhouse effect, described in option 2, is the accurate explanation for the scenario given. The greenhouse effect occurs when certain gases in the Earth`s atmosphere, such as carbon dioxide and methane, trap heat from the sun, preventing it from escaping back into space. This same mechanism
