{'evening sun': [0, 0, 1, 0], 'mid day sun': [0, 0, 1, 0], 'sun': [3, 0, 0, 6], 'evening': [0, 0, 4, 2], 'ozone': [3, 0, 3, 5], 'atmosphere': [1, 1, 4, 7], 'more light': [0, 0, 1, 0], 'radiations': [0, 0, 1, 1], 'temperature': [0, 1, 1, 7]}

Option 1: In the evening, radiation does not travel slowly. The speed of radiation remains constant throughout the day.

Option 2: In the evening, the temperature of the sun does not decrease. The temperature of the sun remains relatively constant throughout the day.

Option 3: Ozone in the atmosphere does not absorb more light in the evening. The presence of ozone in the atmosphere has a consistent effect on the absorption of light regardless of the time of day.

Option 4: The correct answer is option 4. In the evening, the angle at which the sun`s rays enter the Earth`s atmosphere is more oblique. This means that the sunlight has to travel a larger distance through the atmosphere before reaching the surface of the Earth. As a result, a larger portion of the sunlight is scattered and absorbed by the atmosphere, leading to a decrease in the intensity of the sun`s heat. This is why the evening sun is not as hot as the midday sun.

By traveling a larger distance through the atmosphere, the sun`s rays are subject to more scattering and absorption, which reduces the intensity of the heat.
