My home is in the world, what earth, what country, what.

My home is in the east of the world, the east of the earth, and the country is China.

Earth (English name: Earth; Terra (Latin) is the third farthest 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, most of which are covered by salty water bodies such as oceans and bays, and also covered by fresh water bodies such as lakes and rivers, which together form the 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 generates 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.
