Summer
summer autumn winter and spring
Earth's position and angle with the sun makes seasons happen. Whichever side of Earth is closest to the sun is having summer. The side furthest from the sun should be having winter.
The earth turns all around, in summer it is in a position the sun is "higher" or more above, that's why it is summer :-)
Tilt
The position of the Earth to the sun.... when the earth is the furthest away from the sun it becomes winter when the closest its summer
The side of the Earth that is tilted towards the sun will experience summer.
About the same except that they're closer in winter than in summer (the Earth's orbit is an ellipse). The thing that make seasons is not their position but the aspect of the Earth's surface that mainly faces the sun, and that's controlled by the tilt of the Earth's axis.
Summer.
Position B
the tilt on the earth
The sun is pointed on the light of that ray so it will make it comparison.
