What is the earth's layers is most homogeneous?
The mantle is the Earth's layer that is most homogeneous in composition. It is mostly made up of solid rock and minerals, with relatively uniform density and chemical composition throughout.
Where did the oxygen in Earth's atmosphere come from originally?
The oxygen in Earth's atmosphere originally comes from the process of photosynthesis carried out by early photosynthetic organisms like cyanobacteria, which released oxygen as a byproduct. Over time, the accumulation of oxygen led to the development of an oxygen-rich atmosphere.
Where did oxygen originally come from?
Oxygen on Earth originally came from the process of photosynthesis carried out by early single-celled organisms like cyanobacteria. These organisms used sunlight to convert carbon dioxide and water into glucose, releasing oxygen as a byproduct. Over millions of years, this process accumulated oxygen in the atmosphere, leading to the oxygen-rich environment we have today.
What common gas was not part of Earth's original atmosphere?
Oxygen, now about 20% of the atmosphere, was not part of the original atmosphere of hthe Earth. It was produced by plants, after life developed.
What was Earth's surface originally thought to have been?
Earth's surface was originally thought to be flat, based on early observations and beliefs. This notion persisted until evidence from explorations and scientific understanding supported the idea of a spherical Earth.
What process developed after the first prokaryotes developed on earth?
Photosynthesis
Why Earth is homogenous?
The earth is homogeneous because it had rocks all made of the same elements.
Is the mixture of non reacting gases homogeneous?
The mixture of non reacting gases is homogeneous.

What is the background of Velcro?
Velcro was developed originally by NASA as a means of giving people in a weightless environment (in orbit around the Earth) a way to put things down and not have them just float away.
What Products developed from the space program?
Products developed from the space program include memory foam, scratch-resistant lenses, infrared ear thermometers, and satellite television. These innovations were originally created for space missions but have since been adapted for everyday use on Earth.
Why Is air a homogeneous mixture and not a compound?
The composition of air is practically the same at the level of earth.
How did Earth originally form?
from the big bang
What is a mixture of two substances in which the molecules of the substances are evenly mixed?
A Compound mixture. I think it is called homogeneous... <>
Usefulness of a region?
A region is any area on the earth surface homogeneous with respect to announce criteria.
Which planet is the moon thought to have come from originally?
earth
