Pls help I will mark brainiest When comparing temperature variation in the northern and southern hemispheres the hemisphere shows smaller annual temperature variations.

How do the Northern and Southern hemispheres differ in climate and temperature year-round?

The biggest factor in differences in the climate in the Northern and Southern Hemispheres has to do with the distribution of land vs. ocean. The Northern Hemisphere has much more of Earth’s land masses, while the Southern Hemisphere has a larger fraction of ocean.

There is more than one reason this is important. First, land and ocean heat and cool at different rates. Land heats up and cools down much faster (over a period of a day) compared with ocean (over a period of months).

Second, there mountains on land that act as physical barriers to wind flow. Air responds to these barriers in different ways, both from creating local changes upwind and downwind of mountains (wetter in the case of the former, drier in the case of the latter), to having continental effects (the Rocky Mountains create atmospheric waves thousands of kilometers in size that affect the continental US all the way to the east coast and North Atlantic).

Meanwhile, in the southern hemisphere, the Antarctic Circumpolar Current flows unobstructed around the continent of Antarctica. With no land to divert winds, the atmospheric circulation around Antarctica is stronger than at the same latitude in the Northern Hemisphere

The southern hemisphere shows smaller annual temperature variations.

Explanation:

There is large difference in the land mass between the two hemispheres. The land mass between the two hemispheres affects the anual temperature variations

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
