How to draw simple pictures all year round?

The painting method of spring, summer, autumn and winter is as follows:

Tools/raw materials: pen, paper.

1, draw spring first. When it comes to spring, the first thing we think of is the revival of everything, and every grass and tree is sprouting.

Next is summer, which reminds us of the scorching sun shining on us. The sun shines on us and smiles at us.

3. It's autumn. The leaves in autumn are yellow. Then, piece by piece, it landed on the roof beside our road. It is cool in autumn.

4. It's winter. The north wind is blowing and the leaves on the trees are bare. It snowed in winter, and the children made a snowman at their door.

How are the four seasons formed:

There is an included angle (23 26') between the earth's rotation axis and the earth's revolution plane around the sun (ecliptic plane). Therefore, when the earth revolves around the sun, the position of the direct sunlight on the earth will change from 23 26' south latitude to 23 26' north latitude, that is, the tropic of cancer.

When the sun shines directly, the heat and temperature on the earth's surface are high, which is summer; On the contrary, when the sun is tilted, the heat gained on the earth's surface is low, which is winter. When the sun shines directly into the northern hemisphere, it is summer in the northern hemisphere and winter in the southern hemisphere.

On the contrary, when the sun shines directly into the southern hemisphere, it is summer in the southern hemisphere and winter in the northern hemisphere. When the sun shines directly on the Tropic of Cancer, it is the winter solstice (around 65438+February 22nd) and the summer solstice (around June 22nd).

When the sun shines directly at the equator, it is the vernal equinox (about March 2 1) and the autumnal equinox (about September 2 1). The direct sunlight area is located between the Tropic of Cancer and the Tropic of Cancer, so the sun in this area is always almost direct, so the energy obtained from the sun is high in a year, which leads to the high temperature in this area and little change in a year. This area is called the tropics.

In the tropics, there is no change in the four seasons, all of which are summer. Usually refers to all seasons of the year, mainly in the temperate zone, that is, the area between the Tropic of Cancer and the Tropic of Cancer to the Antarctic Circle and the Arctic Circle.
