In this quiz, you will find questions related to the different processes which are responsible for taking water into the atmosphere and then bringing it back to the ground in the form of rain.
________ is a mass of minute water droplets or tiny crystals of ice formed by the condensation of the water vapour in free air at considerable elevations.
The actual amount of the water vapour present in the atmosphere is known as _________
______ is frozen raindrops and refrozen melted snow-water.
When the water containing air becomes saturated, then?
It will be calm
It will be windy above sea and rainy above land
It will start to rain
Clouds will be formed
what does the Rainshadow zone mean?
Windward slopes of the mountains
The leeward side of the mountain
Mountainous area
Coastal area
The alto clouds are found at:
High levels
Mid-levels
Low levels
Low, mid, and high levels
What is the main source of atmospheric moisture?
River
Rain water
Lakes
Ocean surface
The amount of water present in the air is known as?
Humidity
Moisture
Vapour
None of these
When air containing water reaches its saturation point, then?
No more water evaporates from the ground
It leads to evaporation above sea and precipitation above land.
Water vapour forms droplets
The droplets fall out of the clouds
The percentage of moisture present in the atmosphere as compared to its full capacity at a given temperature is known as?
Relative humidity
Specific humidity
Absolute humidity
Saturated air
The air can only contain a certain amount of water vapour before it is saturated. This amount is dependent on:
The temperature of the air
Whether the air is above sea or land
The wind speed
The amount of dust particles in the air
Orographic rainfall is more on?
Windward slopes
Leeward slopes
Plains
Valleys
Which factor controls evaporation?
Temperature
Aridity
Movement of air
All of these
At what temperature the given sample of air becomes saturated?
Freezing point
Absolute zero
Dew point
None of these
What is called the cooling of saturated air?
Evaporation
Condensation
Freezing
Dew formation
