Well, the greenhouse effect is a natural process by which some of the radiant heat from the Sun is captured in the lower atmosphere of the Earth, thus maintaining the temperature of the Earth's surface. The gases that help capture the heat, called “greenhouse gases,” include water vapor, carbon dioxide, methane, nitrous oxide, and a variety of manufactured chemicals. Some are emitted from natural sources; others are anthropogenic, resulting from human activities.
Over the past several decades, rising concentrations of greenhouse gases have been detected in the Earth's atmosphere. Although there is not universal agreement within the scientific community on the impacts of increasing concentrations of greenhouse gases, it has been theorized that they may lead to an increase in the average temperature of the Earth's surface. To date, it has been difficult to note such an increase conclusively because of the differences in temperature around the Earth and throughout the year, and because of the difficulty of distinguishing permanent temperature changes from the normal fluctuations of the Earth's climate. In addition, there is not universal agreement among scientists and climatologists on the potential impacts of an increase in the average temperature of the Earth, although it has been hypothesized that it could lead to a variety of changes in the global climate, sea level, agricultural patterns, and ecosystems that could be, on net, detrimental.
Hope this helps!
Answer:
Ne-21
Explanation:
the 21 represents the mass number. since neon has 10 protons, the mass number is calculated by adding the number of neutrons to 10.
this is because mass number = protons + electrons
so 10 +11 =21
Sunlight ( the source of energy), air (composed mainly of oxygen and carbon dioxide), water, food (nutrients), temperature (a habitat with a right temperature for different kind of organisms).
Answer:
the sample of 200 medium ground finches measured in 1976 (Figure 1). The number of individuals has increased to close to the number of birds present in the population before the drought. However, the most common beak depth has increased from 8.8 mm to 9.8 mm .
