Hot in the summer and cold in the winter. Reason 10

China is located in the northern hemisphere, and the direct point of the sun is up to the northern latitude, that is, the Tropic of Capricorn, and the date of direct shooting of the Tropic of Cancer is the summer solstice. For example, if you take a flashlight to shine on a watermelon (up and down, down south, left, west, right east), you shine on the top third of the position (Tropic of Capricorn), the light in the northern hemisphere will be the most strong, and then at the top (North Pole), a polar day will be formed, (the South Pole) will become a polar night, the earth will turn from west to east, no matter how you turn the North Pole, the light time in other parts of the Northern Hemisphere will increase, so that the surface temperature in the northern hemisphere will rise, the air temperature will also rise, and there will be few cold and high pressure in the north to the south; The sun has a higher angle than in winter, the distance to penetrate the atmosphere is shorter, the solar radiation is stronger, the ground is less shady, and it absorbs more heat, so it forms summer, and the opposite is true in winter.

On the day of the summer solstice, the sun shines directly on the Tropic of Capricorn; On the winter solstice, the sun shines directly on the Tropic of Capricorn. Generally speaking, the sun is close to us in summer, and the sun is far away from us in winter, professionally speaking, that is, in summer, the angle between the sun and the ground should be large, and the angle of intersection should be small in winter, and the angle will be large, of course, it will be more heated, which is equivalent to the direct sun in the afternoon, so it is much hotter, and the morning and afternoon obliquely, so it is cooler.

It's because the sun hits the Tropic of Cancer in the summer, so we're summer, and in the winter, it's the Tropic of Capricorn, so it's winter

Of course, this is true for the Northern Hemisphere, and the Southern Hemisphere is the opposite, and for the Southern Hemisphere, it's true that the summer is closer to the sun and the winter is far away, but that's not the cause of the summer winter

The Earth revolves, and in the summer the direct point of the sun moves near the Tropic of Capricorn. In winter, the direct point of the sun moves to near the Tropic of Capricorn, so it is hot in summer and cold in winter.

Because; The earth rotates, and it revolves around the sun, so some parts of the earth shine sunlight, and some places do not shine sunlight, so it causes some places to be hot and some places to be cold.

The orbit of the Earth is elliptical, and the Earth is far from the Sun in winter and close to the Sun in summer

In fact, the sun shines directly in the summer, and the sun shines obliquely in the winter!! ~

In summer, it is located close to the direct sun, and in winter it is far away (north of the Tropic of Capricorn).

Winter is far from the sun, and summer is close to the sun.

Because the angle of inclination of the earth's axis of rotation causes the sun to irradiate, the heat obtained by the earth's surface is also different. When the sun is directly shining, the heat obtained by the earth's surface is high, and the temperature is high, which is summer, and conversely, when the sun is oblique, the heat obtained by the earth's surface is low, which is winter.

There is an angle of inclination on the Earth's axis, which causes the direct point of the sun to move back and forth between the Tropic of Cancer, which leads to different angles of sunlight and different amounts of energy obtained.

When the sun shines directly into the Northern Hemisphere, it is summer in the Northern Hemisphere and winter in the Southern Hemisphere.

At the spring and autumn equinoxes of each hail year, the sun shines on just half of the earth's surface evenly, and day and night are equally divided around the world.
