You and a friend head to the ocean shore from your home 20 miles inland. Before leaving you measure the temperature and dewpoint at home. Upon reaching the beach, you measure the temperature and dewpoint there as well and find that they are the same as at home. You also observe that the air is MUCH hazier at the beach. Explain why.
