Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the thermoregulation impact?High relative humidity impedes evaporative cooling, increasing the risk of heat-related illness
2. What is the atmospheric processes?Humidity is a precursor to condensation, cloud formation, fog, dew, and precipitation
3. Why can warm air hold more water than cold air?When air is warm, it can hold more water vapor, like a bigger sponge. For example, at 8 °C it can hold about 8 grams of water per cubic meter, but at 30 °C it can hold about 28 grams.
4. How does high humidity make hot days feel sticky?High humidity slows the evaporation of sweat from our skin, so we feel less cool and can get heat stress or heatstroke.

Water Vapor: The gaseous state of water, an invisible component of the atmosphere.
Saturation Point: The maximum concentration of water vapor air can hold at a specific temperature and pressure.
Dew Point: The temperature at which air becomes saturated, leading to condensation.
Evaporative Cooling: The process by which liquid turns into gas, absorbing heat and cooling the surface.
