Which layer of the atmosphere has the lowest density?

As compared to warm fronts,cold fronts move ____________.

Which pair of gases are most abundant within Earth's modern atmosphere?

The two main mechanisms of rain and snow formation within clouds are ____________ and ____________.

In the northern hemisphere,air travels in a ____________ direction around areas of high pressure.

Lines connecting points of equal temperature on a map are termed ____________.

Cold fronts and warm fronts tend to deflect one another,so it is impossible for a warm front to become occluded (overtaken)by a cold front.

As an air mass rises,it generally experiences ____________.

During the Atlantic hurricane season of 2005,so many hurricanes and tropical storms formed that the National Weather Service ran completely through the list of traditional names and had to add names.

The very first Earth atmosphere,forming with Earth itself,was probably dominated by the cosmically abundant gases ____________ and ____________.

Starting from the equator and moving toward either pole,how many rows of global convection cells are present within the troposphere?

Most atmospheric ozone occurs in which layer of Earth's atmosphere?

Laterally,at the surface,winds blow from regions of ____________ to regions of ____________.

Oxygen in Earth's atmosphere built up over time as a result of ____________.

In which layer of the atmosphere does temperature decrease with altitude because most of its heat is derived from the atmospheric layer immediately below it?

The high-altitude jet stream in the northern hemisphere travels from ____________ due to the Coriolis effect on northbound air masses.

The boundary between two bodies of air with differing characteristics (such as temperature,pressure,relative humidity)is termed a ____________.

At high altitude within the troposphere,the global pattern of air flow is from the ____________.

In global convective circulation,air rises at the ____________ and the ____________.

Due to the Coriolis effect,air that is spread northward from the equator is deflected ____________.
