the seasons review Flashcards
what causes the seasons
the tilt of the earths axis
as the earth orbits the sun the axis is always pointing at what
the north star
for part of the year the northern hemisphere is pointed more towards the earth what does that mean for the opposite part of the year
That the southern part is closer to the sun
if the southern hemisphere is pointed more towards the sun does this mean that it is closer to the sun
no because it doesn’t matter about the distance it matter about the angle of where the sun hits
what happens when the sun is directly overhead in the sky
the heat is more intense
there are longer periods of sun when the hemisphere is pointed where
more towards the sun
