Sleet forms when
Rain begins to fall from a thick layer of warm air
(above freezing) as it moves over a thick layer of cold air (below freezing)
Your clothes become damp on a hot summer day because of which of the
following?
The relative humidity is high and your sweat is
not completely evaporated.
What is the definition of aggregation?
The growth of snowflakes as ice crystals
stick together
You plan a day trip into the mountains and want to estimate the
temperature at the mountain peak. You measure an air temperature
of 25°C and the peak is 2.5 km above your starting location. What is
the temperature at the peak if the air is dry (no clouds)?
0°C

cirrostratus
Why is the moist lapse rate less than the dry lapse rate?
Rising moist air forms condensation which
releases heat into the atmosphere
In a thermal circulation what is happening at the surface of the warm
