Ok scince i dident go to school today im making up a test and i need to know...a few things
What is inclined at an angle of 11.5° to Earths roatational axis?
What is the sun directly over at the equinoxes?
Which season begins in the northern hemisphere when the sun reaches its greatest distance south of the equator?
On what date dose the southern hemisphere begin spring?
At the March equinox what season begins in the northern hemisphere?
PLEASE TRY TO ANSWER AS MANY AS U CAN..I am so confused and sick..so i am totally out of it today!

OK, only because of your avatar.
1. A line perpendicular to the plane of the solar system.
2. The Tropics of cancer and Capricorn.
3. Winter
4. September
5. Fall or Autumn

Earth's magnetic axis is inclined approximately 11.5 degrees from the rotation axis. This is why the magnetic pole is around latitude 78.5 (90 - 11.5). The equator is (by definition) exactly 90 degrees from the pole of rotation (i.e., the rotation axis makes a 90 degree angle with the equatorial plane).
At equinox, the sun's declinaiton is exactly 0. This means that it is exactly over latitude 0 (the equator). At the solstice (when the declination reaches 23.4393 degrees), the sun is directly over latitude 23.4393 degrees (the Tropics). As the seasons depend on the cycle of the sun's movement over these latitudes, the year we use for predicting the seasons is called the tropical year.
In December, the Sun reaches its greatest south declinations. In the western civilization scheme, this marks the beginning of winter for the northern hemisphere.
Spring begins on the day of the equinox, when the Sun's declination moves towards the hemisphere. In September (around the 21st), the Sun's declination changes from north to south: at the point when it is exactly 0 (on its way southward), it is the beginning of Spring for the South.
Use the preceding paragraph to figure out what happens in March.

1. The equator is inclined at an angle of 11.5 degrees to Earth's rotational axis.
2. The sun is directly over the equator at the equinoxes.
3. Winter begins in the Northern Hemisphere when the sun reaches its greatest distance south of the equator.
4. The Southern Hemisphere begins spring on either September 22nd or 23rd.
5. At the March equinox, spring begins in the Northern Hemisphere.

(1)Magnetic axis of the earth.
(2)On 22nd March(vernal or spring), and 23rd September(autumnal),the sun shines over the equator.
(3) Winter season
(4)On 23 rd September(autumnal equinox)
(5) Spring season

Maybe you can get the answers by watching wrestling. I hear that everyone who works at NASA gets all their astrophysics information there.
