Wwhat type of system is associated with weather that has lots of clouds and thunderstorms with the possibility of tornadoes? a. low pressure system b. circulatory system c. arctic system d. high pressure system

The appropriate answer is a. A low-pressure system. Low-pressure systems are associated with cloud cover, thunderstorms and relatively high winds. The lower the pressure in the system the higher the wind speed. Examples of low-pressure systems include hurricanes, tropical storms, depressions and cold fronts. High-pressure systems such as anti-cyclones bring fair weather with relatively calm conditions.  

This is what i found “getting into the technicalities, the continental crust has a density of around 3.0 g/cm3 compared to 2.6 g/cm3 of the continental crust. in addition, the continental crust is much thicker than the oceanic crust. the recycling process does not happen to the continental layer.” i hope this you for what your looking for. can you plz mark me brainliest?
