Final answer:
The sun's rays strike the Earth at different angles depending on the tilt of the Earth.
Step-by-step explanation:
In physics, the sun's rays strike the Earth at different angles.
When the earth is tilted towards the sun, the sun's rays have a shorter distance to travel through the atmosphere and strike the Earth more directly, resulting in higher temperatures.
On the other hand, when the earth is tilted away from the sun, the sun's rays have a longer distance to travel through the atmosphere and strike the Earth at an angle, resulting in lower temperatures.
