What are greenhouse gases and how do they affect the climate?
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth’s outgoing energy, thus retaining heat in the atmosphere.
How does greenhouse effect the climate?
The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
What are greenhouse gases and their effects?
What Are Greenhouse Gases? Earth’s greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which all occur naturally), and fluorinated gases (which are synthetic).
What are greenhouse gases explain?
Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. The main greenhouse gases are: Water vapor. Carbon dioxide.
What is the leading cause of greenhouse gases?
The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks.
Why the greenhouse effect is bad?
However, too many greenhouse gases can cause the temperature to increase out of control. The increased greenhouse effect is causing changes in our planet that can affect our lives. The major Greenhouse Gas, carbon dioxide, emitted naturally and by the burning of fossil fuels, stays in the atmosphere a long time.
What activities can reduce the greenhouse effect?
The following is a list of steps YOU can take to reduce greenhouse gas emissions:
- Reduce, Reuse, Recycle.
- Use Less Heat and Air Conditioning.
- Replace Your Light Bulbs.
- Drive Less and Drive Smart.
- Buy Energy-Efficient Products.
- Use Less Hot Water.
- Use the “Off” Switch.
- Plant a Tree.
What are the 5 main climate zones?
Scientists classify, or group, climates into five major climate zones. These zones classify climates by average temperature and precipitation. They are tropical, dry, temperate, cold, and polar.
