Answer:
A large body of water can make the climate of a region more stable, preventing temperatures in the region from becoming extremely low in winter in a temperate climate.
Step-by-step explanation:
The water has a very high specific heat rate, which means that a very large energy expenditure is required to heat or freeze the water. Regions close to large bodies of water, can benefit greatly from this characteristic. Because as the water will take a long time to freeze or heat up, these regions receive a very stable temperature, which is directly benefited by the water.
In this case, in a temperate climate region, where winter is usually very intense and presents low temperatures, the large body of water would take a long time to freeze and this would allow the region around this body of water to receive stable temperatures in winter.
