Ответ:

1. The Sun is our main source of natural light

2. The Sun warms our seas

Answer 2

1. The primary source of natural light on Earth is the Sun. The Sun emits electromagnetic radiation, including visible light, which illuminates our planet during the day.

2. We need the Sun for various reasons. Firstly, sunlight provides energy for photosynthesis, which is crucial for the growth of plants and the production of oxygen. Secondly, sunlight helps regulate our internal biological clocks, influencing our sleep patterns and overall well-being. Additionally, the Sun's warmth plays a role in maintaining Earth's climate and weather systems.

3. The Moon helps us see during the night by reflecting sunlight. When the Moon is visible in the night sky, it reflects the Sun's light back to Earth, providing a secondary source of illumination. The brightness of the Moon's reflection, known as moonlight, can vary depending on the Moon's phase and its position relative to Earth.

4. We can see at night because of various factors. While the Sun is the primary source of light, it also illuminates objects like the Moon, stars, and planets. Moonlight, as mentioned earlier, can provide significant illumination during certain phases of the Moon. Additionally, artificial sources of light, such as streetlights, buildings, and indoor lighting, contribute to visibility at night. Our eyes are capable of adjusting to low-light conditions, and the presence of these light sources enables us to see reasonably well in darkness.
