Question

In Delhi summers are very hot and winters are very cold while Kochi experiences moderate summer and winters.

Answer 1

Delhi experiences hot summers and cold winters due to its location in the dry interior of the Indian subcontinent. It is away from the moderating influence of coastal climate caused by humidity. It is also farther from the Equator than Kochi.
Kochi experiences moderate summers and winters due to its location in the lower latitude of the Indian subcontinent as well as its proximity to the sea. The sea provides a moderating influence to the surface by limiting the range of temperature.
