Answer:
Over ocean-- warmer temperature and low air pressure.
Over the land--- cool temperature and higher air pressure.
Step-by-step explanation:
The air pressure is low in the ocean and higher over the land whereas the temperature over the ocean is warmer and cooler over the land because the land loses heat very quickly when the sun goes down while on the other hand, water of the ocean can't lose the heat very quickly which remain them warmer. This variation in temperature causes the low surface pressure to shift to the ocean and the high surface pressure to move over the land at night.
