Which is an effect of global warming?(1 point)Responseschanging seasons every yearchanging seasons every yearrising sea level over a period of timerising sea level over a period of timeincreasing carbon dioxide in the atmosphereincreasing carbon dioxide in the atmosphereincreasing greenhouse gas concentration in air
All three responses are effects of global warming:
- Rising sea levels over a period of time: As global temperatures rise, glaciers and icecaps melt, resulting in an increase in the volume of water in the oceans which causes sea levels to rise.
- Increasing carbon dioxide in the atmosphere: Global warming is primarily caused by the increase in greenhouse gases, such as carbon dioxide, in the Earth's atmosphere. Human activities, such as burning fossil fuels, deforestation, and industrial processes, release large amounts of carbon dioxide, leading to an increase in its concentration in the atmosphere.
- Increasing greenhouse gas concentration in the air: Greenhouse gases trap heat in the Earth's atmosphere, causing the greenhouse effect. As the concentration of greenhouse gases, such as carbon dioxide and methane, increase, more heat is trapped, leading to further warming of the planet.
answer?
The answer is: rising sea level over a period of time, increasing carbon dioxide in the atmosphere, and increasing greenhouse gas concentration in the air.
The effect of global warming that is listed in the options is "rising sea level over a period of time."
To understand why global warming leads to a rising sea level, we need to consider a few key factors.
Firstly, global warming is primarily caused by the increase in greenhouse gases (such as carbon dioxide) in the atmosphere. These gases trap heat from the sun, leading to an overall increase in the Earth's temperature.
As the Earth warms up, several processes contribute to rising sea levels. One of these is the melting of glaciers and ice caps. When the temperature rises, ice begins to melt, and the liquid water flows into the oceans, causing the sea level to rise.
Additionally, global warming causes thermal expansion of seawater. When water heats up, it expands, resulting in higher sea levels.
Both of these processes, combined with other factors like the melting of ice sheets in Greenland and Antarctica, contribute to the gradual increase in sea level over time.
Therefore, the option "rising sea level over a period of time" is an effect of global warming.
