What is the current trend for atmospheric CO2? What is the climatic consequence of a relatively fast-spreading ridge? Name two greenhouse gases. Is today's atmospheric concentration of CO2 unusual when compared to the last 500,000 years? What is the difference between climate and weather? What is the chemical composition of the Atmosphere? What is a greenhouse gas?
Understand the Problem
The questions are primarily asking for information related to climate science, specifically regarding atmospheric CO2 levels, climatic consequences of geological processes, greenhouse gases, and distinctions between weather and climate. Each question addresses a fundamental concept in environmental science.
Answer
CO2 rising unprecedentedly fast; volcanic activity affects climate; CO2, methane are greenhouse gases; current CO2 levels are unusual; climate vs weather: long vs short-term; atmosphere: mainly N2, O2; greenhouse gases trap heat.
- Atmospheric CO2 levels have increased rapidly, with current concentrations being unprecedented when compared to the last 500,000 years. 2. Fast-spreading ridges often result in more volcanic activity, which can alter climate. 3. Two greenhouse gases are CO2 and methane. 4. Climate refers to long-term atmospheric patterns, while weather is short-term. 5. The atmosphere primarily consists of nitrogen, oxygen, and argon. 6. A greenhouse gas traps heat in the atmosphere.

More Information
Current levels of CO2 in the atmosphere are much higher now than they were for most of human history, mainly due to the burning of fossil fuels. Greenhouse gases like CO2 and methane play significant roles in global warming by trapping heat in the Earth's atmosphere.
Tips
A common mistake is to confuse the terms 'climate' and 'weather'. Climate is the average of weather over longer periods, while weather is the daily or short-term conditions in the atmosphere.
