The earth is half fresh and half polluted

The way to draw the earth that is half fresh and half polluted is as follows:

Tools/materials: white paper, colored pens.

1. First, we need to draw a circle on the white paper. You can also draw an elliptical shape, because the earth itself is not a standard perfect circle.

2. Then we can draw various continental plate models in the middle of the circle. For those with higher requirements, we can draw them according to the physical model. For those with lower requirements, we can draw them directly. Some more irregular shapes will do.

3. After drawing the inner continental plates, we can draw some different house shapes outside the circle. According to our needs, just draw a few around the circle.

4. Draw the shape of the house, and then we can draw the shapes of some flowers, plants and trees around the house to represent the plants on our earth. You can also draw some small animals.

5. Then we can paint the inner panels with different colors, and then paint all other parts with light blue. Because the light blue color represents the ocean.

6. Then paint the trees green, paint the house some colors you like, and finally add some loving slogans, and the entire simple earth painting is completed.

The formation of the earth

The history of the earth is very long. According to radiocarbon dating measurements, the solar system was formed approximately 4.56±0.08 billion years ago, and the proto-Earth was formed approximately 4.54±0.04 billion years ago. Theoretically, the formation of the sun began with the gravitational collapse of a huge cloud of hydrogen molecules 4.56 billion years ago. Most of the collapsed mass was concentrated in the center, forming the sun.

The remaining parts were rotated and flattened, forming a protoplanetary disk, which in turn formed the planets, moons, asteroids, comets, meteoroids and other small solar system objects. The nebular hypothesis maintains that the planetesimals that formed the Earth originated from lumps of gas, ice particles, and dust with a diameter of one to ten kilometers that were left after accretion collapse.
