– The atmosphere's most important constituent for human beings: Oxygen【4:0†source】.
– Process transforming liquid into vapor: Evaporation【4:0†source】.
– Air containing moisture to its full capacity is called: Saturated air【4:0†source】.
– The highest cloud in the sky is: Cirrus cloud【4:0†source】.
– Three types of precipitation: Rain, snow, hail【4:2†source】.
– Relative humidity is: The percentage of moisture present in the atmosphere compared to its full capacity at a given temperature【4:1†source】.
– Amount of water vapor decreases rapidly with altitude because: Air temperature decreases with altitude, leading to reduced capacity to hold water vapor【4:1†source】.
– Cloud formation process: Clouds are formed by the condensation of water vapor in free air at considerable elevations【4:4†source】.
Name the three forms of water in the atmosphere and how is moisture derived in the atmosphere?
The three forms of water in the atmosphere are gaseous, liquid, and solid. Moisture in the atmosphere is derived from water bodies through evaporation and from plants through transpiration.
Define absolute humidity and relative humidity.
Absolute humidity is the actual amount of water vapor present in the atmosphere expressed in grams per cubic meter. Relative humidity is the percentage of moisture present in the atmosphere compared to its full capacity at a given temperature.
Explain the conditions required for the formation of dew and frost.
Dew forms when moisture is deposited in the form of water droplets on cooler surfaces during clear skies, calm air, high relative humidity, and cold nights. Frost forms on cold surfaces below freezing point when excess moisture is deposited as ice crystals under similar conditions to dew but with temperatures at or below freezing point.
Discuss the formation of clouds and classify them based on their types.
Clouds are formed by the condensation of water vapor in the atmosphere at considerable elevations. They are grouped into cirrus, cumulus, stratus, and nimbus based on their height, expanse, density, and transparency or opaqueness.
Explain how evaporation and condensation processes occur in the atmosphere.
Evaporation transforms water from liquid to gaseous state due to heat, while condensation turns water vapor into liquid due to loss of heat. Evaporation occurs when air replaces saturated with unsaturated air, and condensation occurs under specific conditions of cooling and humidity.
