a substance that does not conduct electricity very well
Both the Bergeron process and the collision coalescence process explain precipitation but they each begin with a different kind of cloud what. kind of cloud does aech theory begin with?
Bergeron process:cold clouds
collision process:warm clouds
Which of the 2 theories of percipatation governs the fall of rain from the top of a cumulonimbus cloud? What kind of rain cloud would most likely described by the collision coalescence process?
What is the diff between drizzle and rain?
drizzel is a lighter rain and has very small water droplets
What are the differences between sleet, hail, and freezing rian?
sleet: solid ice pellets that hit the ground that either pile up or melt **frozen before it hits the ground
freezing rain: freeze when they hit something solid forming a smooth glaze of ice all over the solid objects
hail: a larger than normal ice crystal that falls on the earth as a hailstorm ** frozen before it hits the ground

the second day
Name the thre stages of a thunderstorm cell in the order they occur. In each stage indicate whether an updraft ,downdraft or both are present
cumulus stage : only updraft and no precipitation
mature stage: downdrafts,updraft, and precipatation
dissipation stage: only downdrafts and precipatations
If the heavy rain of a thunderstorm lasts for more than 30 minutes s what can you conclude about this makup?
this thunderstorm is made up of several cells
Lightning forms as a result of electrical charge imbalance. Where does that charge originate and why does it occur?
the charge originates in a cumulonimbus cloud and it occurs when water droplets or ice crystals rub against each other in glancing collisions
Which is responsible for most of the light and sound in a lightning bolt the stepped leader or the return stroke?
Where does thunder in a thunderstorm come from?
Why do lightining bolts tend to strike targets that are high?
because the positive charges concentrate on those things trying to get close to the negatively charged clouds as possible
Whats the difference between sheet lightning and a lightning bolt?
sheet lightning is cloud-to-cloud lightning and lightning bolts come from cloud-to-ground
What kind of cloud is nessisary for tornadoe formation?
L ist the five stages of a tornadoe in order. At which stage is the tornadoe most destructive?
