Which is an effect of global warming?
a rising sea level over a period of time
b changing seasons every year
c increasing carbon dioxide in the atmosphere
d increasing greenhouse gas concentration in air
All of the options listed are effects of global warming, but the most direct answer to your question would be:
a) rising sea level over a period of time.
The correct answer is:
a) Rising sea levels over a period of time
Global warming has caused the Earth's temperature to rise, which in turn leads to the melting of glaciers and polar ice caps. The runoff from these ice masses contributes to a rise in sea levels over time. This effect is known as sea-level rise, and it poses a significant threat to coastal areas around the world.
The effect of global warming is a complex issue caused by the increase in greenhouse gases in the Earth's atmosphere. These gases trap heat and contribute to the overall rise in temperature on both land and in oceans. While all of the given options are relevant to global warming, the rising sea level over time, option (a), is directly linked to it.
To understand why the sea level rises due to global warming, we need to look at a few factors. First, as the global temperature increases, glaciers and ice sheets melt, adding more water to the oceans. Second, warmer temperatures cause water to expand, resulting in thermal expansion. Both of these factors contribute to the overall increase in the volume of water in the oceans, leading to a rise in sea level.
To determine the effect of global warming, we can study scientific research and data. Monitoring stations around the world collect data on temperature, atmospheric carbon dioxide levels, and greenhouse gas concentrations. By analyzing the data collected over time and comparing it to historical records, scientists can identify patterns and trends, including rising sea levels.
To access reliable and up-to-date information on the effect of global warming, one can refer to reputable sources such as scientific journals, research papers, and reports from credible organizations like the Intergovernmental Panel on Climate Change (IPCC) or National Aeronautics and Space Administration (NASA). These sources provide comprehensive information on the various effects of global warming, including rising sea levels, changing seasons, and increasing greenhouse gas concentrations.
