That depends on whether you are referring to the fairly small continental tropical (cT) mass that forms around latitude 30°N in the western states, or to the humongous continental polar (cP) mass that occupies a goodly chunk of eastern Canada and sneaks down into the northeast US. Continental masses are dryer than maritime masses, ergo they are the driving forces behind the cold, clear winter weather in the northern states.
If the continental Arctic (cA) air over Canada mixes with the cP, it can get down to the point where we New Englanders close our windows and put on long-sleeved shirts. :-)

Which air mass forms north of 50 degrees north latitude or south of 50 degrees south latitude?
polar continental air mass
What type of terrain and landforms would indicate the prior presence of continental glaciers?
When the glacier melted from North America it left a mass of "heterogeneous" rock debris (loosely termed "glacial drift") etc
What two contenents have the same land mass?
Europe and Asia as well as North and South America.
What air mass symbol is cT?
continental tropical air mass =)
What fraction of the worlds total land mass is south America?
North America comprises 4.8% of the earth's surface, about 24 million square km. (24,221,000). It is 16.5% of earth's land area. The average elevation of North America is slightly less than the average of the seven continents, so its mass would be a little less than 16.5% of the world's total. The average elevation North America is 720 meters. The continental plate extends into the earth below sea level, but what I am shooting for here is a decent approximation for the total mass. The average density of compacted sand is 2080 Kg/m3. Sand is predominantly silicon oxide. There are both lighter and denser materials forming the land mass, but this figure should get us easily within an order of magnitude. Solid basalt is about 3011 Kg/m3, and granite is 2691 Kg/m3. Much of North America rests on basalt, but I'll use the density of granite for my average. Now all we need do is the dimensional analysis. 24,221,000,000,000 m2 * 720 m/2691 Kg/m3 = 6.5 trillion Kg. North America weighs roughly 7 billion short tons.
What air mass covers the smallest area over the North America?
continental polar
The air mass generally does not influence North America?
cpThe air masses with the least influence on the weather of North America are the continental tropical air masses.
How did leif ericson affect the work and knowledge of world?
He didn't affect the world of his time. It is only in hindsight that history records that the Vikings made it to North America. In his life there was no Mass Communication or newspapers so the ancient world had no idea he had gotten to North America.
Which air mass forms north of 50 degrees north latitude or south of 50 degrees south latitude?
polar continental air mass
What is the name of when central America connects north and south America?
Central America,not being a confident itself, finds itself in two continents. The official boundary between North and South America is the center of the waterway that fitness the Panama Canal. So all countries on the continental land mass in Central America, except for Panama, are entirely in North America.
What type of air mass would likely affect Saskatchewan?
Continental Polar
Who discovered laurasia?
Laurasia is an old continental mass that includes North America, Europe, and Asia. It was recognized after the proposal of Alexander Du Toit in his book Our Wandering Continents.
What happens to a maritime Pacific air mass over the North Pacific as it moves inland over the Pacific ocean?
It mixes with continental air and gradually becomes a continental air mass
What continents have more land North America or South America?
North America is larger than South America and has more land mass
I want to ship my SUV across a large body of water called the Pacific ocean from a land continental mass called north America to a smaller land mass called an island in the middle of the ocean. both t?
This is legal, it can be done.
Do north and south America share the same mass land as Asia and Europe?
North and South America are not located on the same land mass as Asia and Europe are. However, North and South America are located on the same land mass as each other, just as Europe and Asia are.
