Does composition of the atmosphere change with elevation?
The atmosphere gos through many cycles and changes. The significant gases in our atmosphere have not changed substantially in the past several centuries. The primary gas is still Nitrogen, then Oxygen.
Scientists believe that earth's early atmosphere changes in composition as a result of?
the appearance of oxygen-producing organisms
What is the Gaia Hypothesis?
The Gaia hypothesis, thought of by scientist James Lovelock in the 1960s, is a preposition that the Earth behaves like a living organism. This is through interactions of the biosphere, lithosphere, atmosphere, and hydrosphere. It suggested that the Earth is capable of responding to changes in its environment like a living cell.
what substance in the upper atmosphere is important to temperature changes in the upper atmosphere layers?
it is the ozone layer in the atmosphere because it is what keeps the atmosphere in check of what is happening in the atmosphere.
The dew point changes most directly as a result of what changes in the atmosphere?
condensation
What changed the composition of the ancient atmosphere on Earth?
When plants and animals evolved, this made changes in the atmosphere on Earth

Why does the color of sunsets vary day to day?
Because the composition of the atmosphere changes from day to day (specifically, the composition of particulates). These are what scatter sunlight in ways that can make sunsets colorful.
What are the main ingredients in the atmosphere?
The air we breathe near sea level is approximately 78% nitrogen, 21% oxygen, and 1% other. The exact composition changes at different levels in the atmosphere.
What changes a rock's composition?
Chemical Changes
Chemistry is primarily concerned with the composition of and changes in what?
The composition of everything and transfer of electrons. Changes in bonding and structure of compounds.

Physical changes do not changes the original what of matter?
Chemical composition
What are phyisical changes?
Changes that occur when the composition remains the same
What variable changes to test the hypothesis?
independent varibles
What properties refer to a substance's ability to undergo changes that alter its composition and identity?
Chemical changes
