What is the difference between world and earth ?

1 Earth is an astronomical and geographical concept that refers to the solar system.

of a planet. 2 The world is a philosophical concept: it refers to the sum of all things in nature and human society, it includes the earth, and the earth is only one thing in the world.

3 Universe: 1) Refers to the infinite space that includes all celestial bodies. 2) the totality of all matter and its forms of existence, which is equivalent to the "world", but with a bias towards the material aspect; On the other hand, the "world" encompasses both matter and events.

The world and the earth are two different concepts, and although they both contain the existence and form of matter, they have certain differences in scope and meaning.

The world is a philosophical concept that refers to the infinite space that includes all celestial bodies, including the sum total of everything such as the earth, human beings, and human society. It encompasses the earth, but is more focused on referring to the physical aspect, but also includes the occurrence and development of events.

Earth, on the other hand, is an astronomical concept and is one of the planets of the solar system. It binds all things with its own gravitational pull and forms the place of human life in many ways. The earth is the common home of all mankind and the only celestial body in the universe known to mankind to have life.

In summary, although both the world and the earth contain the existence and form of matter, the world is a philosophical concept that emphasizes the totality of matter and the infinity of space; The earth is an astronomical and geographical concept, specifically referring to a planet in the solar system, which is the place where human beings live.

Earth is a planetary entity, and the world is a collective term for our plane.

The earth is an entity, and the world is just a concept.

There is an earth in the world. Earth is one of the eight planets in the solar system, the third in order of near and far from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun. The Earth rotates from west to east while revolving around the Sun.

Now 4.046 billion years old, it has a natural satellite, the Moon, and the two form a celestial system, the Earth-Moon System.

It originated from the primordial solar nebula 4.6 billion years ago. The Earth's equatorial radius is kilometers, the polar radius is kilometers, the average radius is about 6371 kilometers, and the equatorial circumference is about 40076 kilometers. The surface area of the earth is 100 million square kilometers, of which 71% is oceans and 29% is land.

Earth

The Earth is the third planet in the solar system from the inside and outside, and it is the terrestrial planet with the largest diameter, mass and density in the solar system. The surface area of the earth is 100 million square kilometers, of which 71% is oceans and 29% is land.

The interior of the earth has a core, mantle, and crust structure, and the outside of the earth has a hydrosphere, atmosphere, and magnetic field.

Summary. The Earth system is formed by the interconnection of the geosphere, including the geosphere and the biosphere, which includes the solid earth system (lithosphere, topsoil) and the physical climate system (hydrosphere, atmosphere), the biosphere, also known as the global ecosystem, including all living and living systems on the earth.

The Earth system is formed by the interconnection of the geosphere, including the geosphere and the biosphere, of which the geosphere includes the solid earth system (lithosphere, surface bridge and soil layer) and the physical climate system (hydrosphere, atmosphere), the biosphere is also known as the global branching system, including all living and living systems on the earth.

Can you add, I don't quite understand it.

The concept of the Earth system mainly includes the following connotations, that is, the Earth is a system composed of two engines and driven. One engine is the emitting and primary heat of the cavity inside the sphere, which drives and sustains the movement of the Earth's lithosphere, and the other is the Woo's Sun, which drives and sustains the weathering, denudation and sedimentation processes on the Earth's surface.

I think to put it simply, the world is a broad word, and the earth is a narrow word, and the earth is the planet, and the world has other meanings, for example, if a person stays in a 100-square-meter space from birth to death, then the world is only so big, and this is the world to him, and for example, aliens, they live on aliens, and aliens are their world, so the world is a concept, and you can't say that it is the earth.
