    Explanation:
    • 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. 
    • 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 only statement 1st is correct.
