Humidity is the amount of water vapour present in air. The capacity of air to absorb water vapour increases with increase in temperature. Absolute Humidity is the weight of actual amount of water vapour present in unit volume of air.

Notes:
Stratus clouds are horizontal.
They are stratified or layered clouds cover big portions of the sky.
These clouds are usually formed due to the mixing of air masses with various temperatures or due to loss of heat.
The presence of stratus clouds means chilly, overcast day.

Nimbus clouds are usually black or dark grey.

Notes:
Air masses occur over a homogeneous area, when air remains for a sufficiently long time, it acquires the characteristics of that area. Homogeneous regions over which air masses form are called source regions.

The movements of water in oceans can be categorized into currents, waves, and tides. Ocean currents are the large masses of surface water that circulate in regular patterns around the oceans.
