- Temperature changes are induced by variations in heating between highly urbanised and semi-urbanized regions, as well as the presence of open and green spaces in the surrounding areas. The average temperature variance in urban heat islands is from 3 to 5 degrees Celsius. Hence statement 1 is correct.
- This spike in heat is mostly caused by urban infrastructure and buildings constructed of concrete and asphalt, where heat is trapped and unable to disperse efficiently. The trapped heat between establishments composed of concrete and asphalt causes urban heat islands. Hence statement 2 is not correct.

Explanation:
Urban heat island (UHI) is a phenomenon where urban areas experience higher temperatures compared to their rural surroundings. Let's analyze the given statements to identify the correct answer.
Statement 1: Urban heat islands have a mean temperature variation range between 3 to 5 degrees Celsius.
- This statement is generally correct. Urban heat islands can indeed have a temperature difference ranging from 1 to 10 degrees Celsius or even more, depending on various factors such as city size, population density, land use patterns, and weather conditions.
Statement 2: Urban heat island is basically a phenomenon associated with the greenhouse effect of the gases.
- This statement is not correct. While the greenhouse effect does contribute to rising temperatures globally, the urban heat island effect is primarily a result of human activities such as the heat retention properties of buildings and roads, lack of vegetation, waste heat generation, and more. It is more about local heat retention and not directly related to greenhouse gases.
Therefore, the correct answer is Option B - 2 only. Urban heat islands are influenced by a variety of factors beyond greenhouse gases, making statement 2 incorrect.
