In the carbon cycle, carbon that is stored for millions of years is found in the form of —

• fossil fuels that either remain under Earth's surface or release carbon dioxide when burned.

• carbon monoxide that is deep under oceans and is released as solid graphite.

• carbon crystals trapped in plant roots that pass from plant to plant before they are finally released into the atmosphere.

• vapors of carbon compounds that stay in clouds until Earth's orbit is in line with Mercury, once every two million years.

Four students were asked to describe the influence of human activities on Earth’s climate. Their responses are shown below.

Student Influence of Human Activity on Earth’s Climate

1 Human activities affect Earth’s climate in specific regions; however, they do not have an impact on global climate patterns.

2 Human activities, such as burning fossil fuels, increase greenhouse gases in the atmosphere, which leads to global warming.

3 Human activities cause immediate and predictable changes in Earth’s climate, but they do not lead to lasting long-term effects.

4 Human activities, such as urbanization, increase the number of green spaces and improve air quality, which can help reduce Earth’s surface temperature.

Which student correctly described the influence of human activities on Earth’s climate?

• 1

• 2

• 3

• 4

What is global warming?

• increase in the average temperature of the Earth's air and oceans.

• Due to an increase in populations of plants and trees

• a result of less fossil fuels being burned
