How was the earth made?
The dust which was in the cloud agglomerated to form “grains of sand”, then large rocks, and, attracted by the force of gravity, these rocks assembled during violent collisions which do melt the rock! Boom! A bit like a snowball that picks up everything in its path.
The day/night alternation: The Earth rotates on itself while being tilted with respect to the Sun. The fact that it turns on itself means that there is always a part exposed to the sun: it is day there, while another part remains in the shade: it is night. During rotation, this is gradually reversed.
Here is a summary history of the formation of the Earth. Our planet dates back about 5 billion years, while the sun was gradually forming. The first moments of the Earth have little to do with its current appearance and many mysteries still hang over its evolution.
Land is a passive factor while labor is an active factor of production. In reality, it is the work which is in cooperation with the earth which enables production.
Some economists believe that there are basically only two factors of production: land and labor. The land they say is appropriated to the gifts of nature by human labor and the contractor is only a special variety of labor.
The Earth is only halfway through its existence. The sun will grow and transform the Earth into a gigantic desert, then into a ball of molten lava, before turning it into a cloud of gas and dust.
