How to draw the earth theme poster?

The earth theme poster is drawn as follows:

Draw a big circle first, just like the earth, then draw several continents on the earth, then draw the right hand, then draw the other left hand, then draw a big circle outside, and finally write English letters.

earth

The earth is the third planet from the sun and the only celestial body known to mankind that breeds and supports life. About 29.2% of the earth's surface is land composed of continents and islands. The remaining 70.8% is covered by water, mostly salty water bodies such as oceans and bays, but also fresh water bodies such as lakes, glaciers and rivers, especially glaciers * * * isomorphic to form hydrosphere.

Most of the polar regions of the earth are covered with ice. The outer layer of the earth is divided into several rigid tectonic plates, which have migrated on the surface for millions of years, but still remain active inside, including a solid iron core, a liquid outer core that produces the earth's magnetic field, and a convective mantle that drives the plate structure.

The earth's atmosphere is mainly composed of nitrogen and oxygen. Tropical regions receive more solar energy than polar regions and redistribute it through atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. The climate of a region depends not only on latitude, but also on altitude and proximity to the region and the ocean. Severe weather such as tropical cyclones, thunderstorms and heat waves mostly occur in vast areas and have a great impact on life.

The gravity of the earth will interact with other objects in space, especially the moon, which is the only natural satellite of the earth. It takes about 365.25 days for the earth to make a revolution around the sun.

The rotation axis of the earth is inclined relative to its orbital plane, so seasons are produced on the earth. The gravitational interaction between the earth and the moon causes tides, stabilizes the direction of the earth on its axis, and gradually slows down its rotation speed. The earth is the home where human beings live together, and there is only one earth for human beings.
