Earth travels in an orbit as it revolves around the Sun. As it revolves, Earth's axis is always tilted in the.

Question

same direction.

Part A What is the weather like in the Northern Hemisphere when the Northern Hemisphere tilts toward the Sun? Explain the causes of this weather.

Part B What is the weather like in the Southern Hemisphere at the same time?

P.S. Thanks for helping me double check my answers to my 4th graders HW.

Answer 1

A. Summer, because sunlight shines more directly down on the ground and the polar gets sunlight 24 hours a day.

B. Winter, because sunlight shines more obliquely on the ground, and the polar area gets no sunlight at all.

Answer 2

When the earth is tilted toward the sun (Jun, Jul, Aug) the northern hemisphere is warm because there are more hours of daylight. The reverse is true in Jan, Feb, Mar when the Southern hemisphere receivesthe most sunlight. As the earth is closer to the sun at this time of year the southern hemisphere is warmer than the northern is in it's summer.

Answer 3

Ok then

Part A Summer...
Part B Winter

The main cause of the weather would be that the hemisphere pointed toward the sun is physically closer to the sun and that the hemisphere pointed away is farther away...also that the hemisphere pointed at the sun will be exposed to sunlight for a longer period of time (longer days/shorter nights) and that hte opposite hemisphere will get less sunlight (longer nights and shorter days) other real causes of the weather really does depend on the hemisphere...amount of water there (the southern hemisphere has much more, thus taking a longer time to change from hot to cold and back), El Nino, recent greenhouse gas emissions, the current size in the hole of the ozone layer over Antarctica, and possibly where the sun is in it's current activity cycle.

most of the time high school students come on and ask questions in the format you presented it in hoping for a quick/easy answer.

I'm a teacher too...sorry about the rant.



Clear Skies!

Answer 4

When the Northern hemisphere is tilted toward the sun, latitude 23ºN essentially gets about 1100 W/m^2 directly. When that same patch of ground is tilted the other way, the sunlight is hitting at about 46º, so the effective solar irradiance is only about 1100/sqrt(2) W/m^2, or about 780 W/m^2.
