(a) Explain, in detail, why winter temperatures are cooler than summer temperatures. Refer to
the position of the Earth relative to the position of the Sun.

(It’s to do with earth , sun , moon not geography )

The correct answer is:   [b]:   "physical systems" .

The answer is gross domestic product. hope this

It's probably because the earth is actually tilted and is not straight when orbiting the sun. that's why when it's winter here, it's summer in the southern hemisphere. in the wintertime in the northern hemisphere, it's colder here because it's tilted away from the sun and the southern hemisphere is tilted closer to the sun (i believe this is the case anyways)
