What are the two most important variable gases that affect weather and climate?
Nitrogen and oxygen, which make up more than 99% of Earth’s atmosphere, have a bigger influence on climate than other components of the atmosphere.
Which of these has the greatest effect on weather and climate conditions on Earth?
On the surface, the greatest factor affecting Earth is sunlight. Sun provides energy for living organisms, and it drives our planet’s weather and climate by creating temperature gradients in the atmosphere and oceans.
What are the most important gases for weather and climate?
The most abundant gas in the atmosphere is nitrogen, with oxygen second. Argon, an inert gas, is the third most abundant gas in the atmosphere.
What is the importance of atmospheric gases in the atmosphere?
Atmospheric Gases Are Indispensable for Life on Earth
Without the atmosphere, Earth would look a lot more like the Moon. Atmospheric gases, especially carbon dioxide (CO2) and oxygen (O2), are extremely important for living organisms. How does the atmosphere make life possible?
Which two factors have the greatest effect on climate?
The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important.
Which greenhouse gas has the greatest effect on climate?
Major greenhouse gases include carbon dioxide, methane, nitrous oxide, and various synthetic chemicals. Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities.
What property of the atmosphere has the greatest effect on air pressure?
Why does the troposphere experience the greatest amount of atmospheric pressure compared to the other atmospheric layers? It contains a high concentration of gas particles.
How does the atmosphere affect weather and climate?
Tremendous quantities of energy are continuously fed into the atmosphere, setting it into motion and creating weather. … Absorption of this energy warms the surface of the earth and heat is exchanged between the earth s surface and the lower atmosphere.
What are the two most important variable gases in the atmosphere?
The table indicates that nitrogen and oxygen are the main components of the atmosphere by volume. Together these two gases make up approximately 99% of the dry atmosphere. Both of these gases have very important associations with life.
