Fog is caused when cool moist air moves in from over the water and goes over the cooler land.

Yes, that's correct! Fog is primarily formed when warm, moist air encounters cooler air or surfaces. When cool, moist air from over a body of water moves over land that is significantly cooler, the air cools down, leading to condensation of water vapor. This condensation forms tiny water droplets, resulting in fog. There are different types of fog, such as:
1. **Radiation Fog**: Formed when the ground cools quickly at night, causing moisture in the air near the surface to condense.
2. **Advection Fog**: Occurs when warm, moist air moves horizontally over a cooler surface, such as water or cold land, similar to the scenario you described.
3. **Upslope Fog**: Forms when moist air is forced up a slope (like a mountain), where it cools and condenses.
4. **Steam Fog**: Occurs when cold air moves over warmer water, causing evaporation and then condensation of the moisture in the cooler air.
These processes illustrate how the interaction of temperature and humidity plays a crucial role in fog formation.
