Summers are caused by ____
A
a combo of longer days and more direct rays from the sun
B
less direct rays from the sun
C
longer days and shorter nights
D
more direct rays and shorter days
Explanation: 

Detailed explanation-1: -The factor that creates seasons is it’s axis tilt, which makes part of the Earth receive more sun than the other lower half. That’s why the equator has the most sun overall. Every day has the same 24 hours but during the summer the days are longer and it is exposed to more sunlight.

Detailed explanation-2: -For part of our orbit the northern half of Earth is tilted toward the Sun. This is summer in the northern hemisphere; there are longer periods of daylight, the Sun is higher in the sky, and the Sun’s rays strike the surface more directly, giving us warmer temperatures.

Detailed explanation-3: -During the summer solstice, the Sun shines most directly on the Tropic of Cancer, 23.5 degrees north of the equator, giving its most direct energy on Earth to the Northern Hemisphere.

Detailed explanation-4: -As the Earth circles the Sun during the year, half of the Earth get more or less sunlight than the other half of the Earth. In the summer months, the northern half of the Earth, where we live, tilts towards the Sun. This means we get more sunlight, making the days longer.

Detailed explanation-5: -Because the Sun is more directly overhead, shadows are smaller in the summer than in the winter. In the winter, the northern part of Earth is tilted away from the Sun. That means the sunlight is not coming in as directly. So, shadows during the winter are longer.
