When sunlight hits Earth at an angle, what happens to the energy?

• It is spread over a larger area, reducing the energy per unit area.

• It becomes more concentrated, increasing the energy per unit area.

• It is completely absorbed by the atmosphere without dispersion.

• It instantly converts entirely into heat.

Why is summer warmer than winter?

• Because of the tilt of the Earth's axis, which results in longer daylight and higher solar altitude in summer

• Because the Earth is closer to the Sun during summer

• Due to volcanic activity releasing extra heat in summer

• Because unpredictable weather patterns randomly increase temperatures
