equator means suns rays are more concentrated as cover a smaller area

earths curve means rays are spread larger as poles meaning less concentrated rays

Question 2

Amount of atmosphere

Answer 2

at the tropics the rays travel less distance meaning they have to pass through less atmosphere meaning less energy is absorbed through absorption and reflection

at the poles the rays pass through a lot more atmosphere as they are further away meaning more enemy gets absorbed and reflected

Question 3
