Why do you see so little deuterium today?
When the Earth first formed, there was an abundant amount of deuterium in the atmosphere. Today, most of the deuterium has fused into helium and because of that, there is little deuterium left.
The water on Earth today is what?
the water the earth was formed with
How did the primitive atmosphere differ from atmosphere today?
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.

What is wrong with earths atmosphere today?
Today the Earth's atmosphere is being destroyed by all the pollution by cars and power plants.
How has earth atmosphere changes since it first formed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
What is the current theory formation of the moon?
Scientists believe that the Moon has formed by a huge meteorite that hit Earth a very long time ago, sending parts of Earth's crust into its atmosphere. These parts started orbiting Earth for quite some time, then got together and formed into the Moon that we know of today.
Did volcanoes create life?
After loss of the hydrogen, helium and other hydrogen-containing gases from early Earth due to the Sun's radiation, primitive Earth was without an atmosphere. The first atmosphere was formed by gases leaking out from the interior of the early Earth, which still goes on today in volcanoes. Without an atmosphere, life would not have formed.
Was the earth's atmosphere always the same?
No, actually it took a period of about 2.5 billion years for the atmosphere to be were it is today.
Why did the earth's atmosphere change after it was first formed?

Why do more ultraviolet waves reach earth today?
More ultraviolet waves reach earth today because the atmosphere is changing and they do not get filtered out.
