Question

1) ______ Hg. = Standard Atmospheric Pressure (the average atmospheric pressure, per square inch of the atmosphere around the surface (sea level) of the Earth).

2) The ________starts at the Earth's surface & extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the densest, and is where almost all weather occurs.

3)___________ is the formation of a new front or the regeneration of an old one. While frontolysis is the dissipation of a front.

4) ___________naturally occurs in higher levels of atmosphere (stratosphere), protects living matter from ultraviolet electromagnetic radiation, and is destroyed by pollutants, such as Chlorofluorocarbons.

5) _______ __________is the ratio of existing vapor pressure to saturation vapor pressure (in %).

6) 1km = 0.621mi -- therefore, the base of a cloud 1mi above the ground is equal to 1.609 km above the ground

False

False

Explanation / Answer

1.760 mm Hg is the standard atmospheric pressure.

2. Troposphere is the densest part of the atmosphere where almost all weather condition takes place.

3.Frontogenesis is the formation of a new front or the regeneration of the old one.

4.Ozone is the layer present in the stratosphere which protects us from harmful UV rays.

5.Relative humidity is the ratio of the exisiting vapour pressure to saturation pressure.

6.True , as 1 mile equals 1.609 km
