1. The greenhouse effect is a natural atmospheric process that has a tremendous impact on Earth. Describe this process, including what causes it, the factors that influence it, and how it affects Earth.
- The greenhouse effect is when the heat from a planet's air warms the planet's surface to a temperature above what it normally would be without its air. What causes the greenhouse effect is that energy comes from the sun and reflects off of the earth’s surface and then goes back to the atmosphere as a bunch of heat. It affects the Earth by making the atmosphere warm.
2. Identify the major greenhouse gases found in Earth's atmosphere.
- The common gases found in our atmosphere are: carbon dioxide, methane, water vapor, and nitrous oxide

5. Changes in the concentration of greenhouse gases can cause changes in Earth's average surface temperature. What other natural factors or events also can cause long-term changes in surface temperature?
- Ice cores, the flow of water, and deep sea cores. Ice cores and sea cores tell a lot about how the climate changes. How the water moves in the ocean, how the ice gets frozen and unfrozen time and time again, and the flow of water tells how the water has been flowing through and making its way through icy, hot, or broiling rivers; also other types of waterways.
6. How long have consistent weather measurements been collected and recorded throughout the United States?
- NOAA has been using tools since the 1800’s to observe and figure out the weather.
7. Atmospheric composition and conditions are different today than at other times in Earth's history. What types of things do scientists examine to learn what the atmosphere was like hundreds, thousands, or even hundreds of thousands of years in the past? Specifically, explain how a history of climate can be reconstructed from an ice

There are quite a few gases that are responsible for the warming of the earth’s climate. The list mostly includes gases like water vapor, carbon dioxide, methane, and ozone (Cause and Effect…). The way water vapor affects the climate is by keeping the air moist. When the air is moist it keeps the heat from escaping out to space, forcing the heat to stay in our atmosphere.
There are a lot of ways scientist can predict climate like the soil, coral reefs, digging in oceans and lakes and coring into glaciers. Ice cores help them by seeing how the planet's climate was thousands of years ago. These ice cores come from Antarctica, Greenland and any places with glaciers. These ice cores can help predict future climates earth may go through, but it is getting harder to predict. The way they can predict the climate is with the different layers of ice that is formed after a season of snowfall. They can look at these layers and can find different particles in the ice and whatever those partials are can help them predict what year it’s from and what the climate was like then. The oldest ice core dated back 800,000 years
The major greenhouse gas is water vapor. Then there is carbon dioxide, plus a few trace gases (Easterling & Karl, 2011, para4). Carbon dioxide enters the atmosphere by natural processes and by human actions such as burning fossil fuels. Methane, nitrous oxide, and fluorinated gases are all emitted into the atmosphere by human activities (U. S. Environmental Protection Agency, 2010, Greenhouse Gas Overview section).
It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).
Paleontologist use tools, such as ice cores and fossils, to determine how Earth has changed over the ages. Molds, Cast, Petrified, Carbonized and Trace fossils are the most commonly found fossils. Ice cores are tubular samples of snow and ice that has built up over thousands of years. With the help of the fossils and ice cores, scientist are able to tell Earth’s climate, environment, and changes in the surface from 4.6 billion years ago.
An ice core is a cylinder of ice that is drilled out of ice sheets and glaciers, allowing scientist to see what the climate was like on Earth, up to millions of years ago. Each time it snows, the previous layer is packed down, creating ice. Each layer of ice is a band on the ice core, light bands being summer ice and darker bands being winter ice. By studying ice cores, scientists can discover what the climate was like by looking at the air bubbles, dust, pollen and other particles present in ice cores. The textures, colors, and air bubbles are important clues that help scientists discover more of Earth’s history.
The greenhouse effect put simply is gases in the atmosphere trapping heat causing the average temperature on the earth to slowly increase over the year. The reason why it is such a hot topic is because this not only effects
Throughout the 4.5 billion years of its existence, Earth’s climate has oscillated between episodes of cold and warmth during different periods in its history. Earth has experienced periods of ice ages where continental-sized glaciers covered the planet. During Earth’s warmest periods, the polar regions of the world today were completely ice free. Though there were no humans on Earth billions of years ago to describe these dramatic climate variations, Earth was still able to keep records of the past. Climate archives have proven to be significant in providing clues of past climates and also gives us information to help predict future climatic events. Climate archives contain many indicators of past
Greenhouse effect – warming that result when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically
The primary cause of climate change is the human expansion of the greenhouse effect. The greenhouse effect is a natural occurrence, which NASA defines as “the warming that results when the atmosphere traps heat radiating from space” (NASA). During the greenhouse effect, heat from the sun passes through the atmosphere, which is made up of various gases. When the heat from the sun reaches the surface, some of it radiates away from Earth, back into space. However, some of the gases in the atmosphere, known as greenhouse gases, absorb this heat, preventing it from escaping (World Meteorological Organization). The greenhouse effect keeps the Earth at a habitable temperature. The World Meteorological Organization, or WMO, states that the greenhouse effect and
The forth-major gas is methane. Methane also traps heat in to the atmosphere like carbon dioxide, but methane has a less harmful effect on
land and as it rises it hits the o-zone layer and bounces back into the earth
There is a serious situation is occurring on planet Earth that is causing a significant and harmful effect on communities, health, and the climate. It is Global Warming which can be defined as the constant heating of Earth 's surface, oceans and atmosphere. In order to understand global warming, the most important basic is to figure out how the of greenhouse effect plays an important part in its development. The greenhouse effect is caused by increased levels of carbon dioxide (CO2) that trap heat in the atmosphere that keeps the Earth warm. The information this text will discuss is the meaning of global warming, the causes, and most importantly how citizens can help to rectify the situation. Humanity must tickle this problem immediately before the consequences increase and affect the entire planet.
Greenhouse gases are compounds in the atmosphere that can trap and hold extra heat, which increases the temperature in the atmosphere. Greenhouse gases is the cause of the greenhouse effect that leads up to global warming. The greenhouse effect is the trapping of the sun’s warmth in the lower atmosphere that is due to the visible radiation from the sun. The solar radiation reaches the Earth’s atmosphere, then the rest of the sun's energy is absorbed by the oceans and lands which result in the heating of the Earth. After that the heat from the Earth goes towards space, some of the heat is trapped in the atmosphere by greenhouses gases which make the Earth warm enough to tolerate living life. The burning of fossil fuels and land clearing start to increase the number of greenhouse gases which travels into the atmosphere. The result of trapping extra heat cause the Earth’s temperature to rise. Scientist's has proven that the constant increase of heat in the atmosphere is caused by humans. The reason humans are proven guilty for the increase of global warming is because of the amount of carbon that is put into the atmosphere. Carbon is released from burning coal, oil, and gas or cutting down and burning forests. Carbon (CO2) is known as the main source of heat-trapping gas which is mainly responsible for the increase of warming over the years. The removal of trees is another cause of global
