Subsidence is the motion of a surface as it shifts downward relative to a reference level such as sea level.
What is soil?
The uncosolidated mineral or organic material on the immediated surface of the earth that serves as a natural medium for the growth of the plants.
What are the factors affection soil formation?
3. Parent material
5.Organic processesSoil texture
is a determined by the relative proportion of the particles of different size.
3 properties of clay
Three types of soil water?

pressure change with height?
Air mass move from high pressure to low pressure
what is air mass
movenment of the air masses due to difference in pressure
Movement of air mass from where to where
change of elevation high to low
what causes Coriolis effect and how does it manifested in northern and southern hemisphere.
Air mass moves from high-pressure region to low-pressure region.
Which front produces narrow band of thunderstorms.
4types of weather fronts
cold, warm, stationary, and occluded
What are the three stages of thunderstorm, what direction is air moving in each stage
Cumulus stage- uplifting
Mature stage- cold down, warm up
dissipate stage- downdraft
What are three types of lighting
ground to ground
cloud to cloud
ground to cloud (rare)
How to uplift a air mass
Condensation of water releases latent heat keep the air mass uplifing.
how is super cell different
Rotating updraft, spinning starts due to changing winddirection.
What is a tropical cyclone
Storm system characterized by a low-pressure center surrounded by a spiral arrangement of thunderstorms that produce strong winds and heavy rain
