Which description refers to fog? Oburns off when it gets dark extends up to 10 miles into the sky Ois found in areas near bodies of water oforms when the ground warms at night after a cool, dry day
The Correct Answer and Explanation is:
The correct description that refers to fog is:
“Is found in areas near bodies of water.”
Explanation
Fog is a type of low-lying cloud that forms near the Earth’s surface and significantly reduces visibility. It typically develops when water vapor in the air condenses into tiny liquid water droplets, often under calm and cool conditions. Among the options provided, the most accurate description of fog is that it “is found in areas near bodies of water.”
Fog commonly forms in coastal or lake regions because these areas have higher humidity due to the evaporation of water. The presence of a water body increases moisture content in the air. When the air cools—especially at night—this moisture condenses into fog. For example, cities like San Francisco frequently experience fog due to the nearby Pacific Ocean and the contrasting warm inland air and cool ocean currents.
Let’s clarify why the other options are incorrect:
- “Burns off when it gets dark” – This is inaccurate. Fog typically burns off when it gets light (during the day) due to solar heating, which evaporates the fog droplets. Fog usually forms at night or early morning and dissipates after sunrise.
- “Extends up to 10 miles into the sky” – This is characteristic of high-altitude clouds like cirrus or cumulonimbus, not fog. Fog typically remains within a few hundred feet of the ground.
- “Forms when the ground warms at night after a cool, dry day” – This describes a condition more related to the formation of dew, not fog. Fog generally forms when the ground cools at night, chilling the air near the surface and leading to condensation.
In summary, fog most commonly forms in areas with high humidity, especially near bodies of water where the air is moist, and the cooling of air leads to condensation near the ground.
