What is the variation law of the sun's height in a day?

The change of the height of the sun in a day is caused by the rotation and revolution of the earth itself. In the process of the earth's rotation, the position of the sun in the sky changes constantly, and after a period of one day, the changing law of the sun's height in one day is formed. The changing law of the sun's height is mainly manifested in the following points:

1. When the sun rises in the east, its height gradually increases. In the first hour after sunrise, the change of sun height is the most obvious, and the sun height increases by about one degree per minute.

When the sun moves from the highest point to the west, its height gradually decreases. In the afternoon, the height of the sun reaches its maximum, and then gradually decreases until the sun sets at night.

3. The height of the sun is affected by the season and geographical location. In the equatorial region, the height of the sun is the highest at noon; In the northern hemisphere, the height of the sun is the highest in summer and the lowest in winter.

4. At night, I have no idea about the height of the sun.

The changing law of solar height is also influenced by weather, time and geographical location. In sunny weather, the change of sun height will be more obvious, while in rainy weather, the change of sun height may be obscured or blurred, which is difficult to observe clearly.

The changing law of the height of the sun is caused by the movement and rotation of the earth, which involves many factors and has an impact on our daily life, navigation, meteorology and plant growth. Understanding the changing law of the sun's height will not only help us to better understand nature, but also help us to use solar energy more effectively.

The relationship between the height change of the sun and life

1, the change of the height of the sun can be measured by observing the position of the sun in the sky, the projection of the sun, the sundial and other tools. In ancient times, people relied on sundials to measure the height of the sun and calculate the time. Modern science and technology can also calculate the change of sun height through satellite positioning and other technologies.

2. The change of the height of the sun can also help us to make a general orientation judgment. At noon, when the sun is the highest, we can roughly judge our position according to the position of the sun in the sky, which is beneficial to navigation when we get lost.

3. The change of solar height also affects the intensity of sunlight on the ground, and then affects the temperature and meteorological conditions. The higher the height of the sun, the greater the intensity of sunlight on the ground, the higher the temperature, and the easier it is for airflow to form the troposphere, which is beneficial to rainfall.

4. The change of the height of the sun also has an important influence on the growth and reproduction of plants. The higher the height of the sun, the stronger the light, which is suitable for photosynthesis and promotes plant growth; However, if the height of the sun is too low, it will easily lead to plant dysplasia and affect the reproduction of flowers and fruits.
