Explain how the carbon, oxygen, and nitrogen cycles are similar.
The carbon, oxygen, and nitrogen cycles are all biogeochemical cycles. They show the movement of elements through living and nonliving components of the Earth. Carbon, oxygen, and nitrogen, are essential components of life that pass through organisms and nonliving components, but are never used up.
Landfills produce methane, which is a greenhouse gas and contributes to global warming.
Compare the use of coal to the use of petroleum from 1800 to 2004.
The use of coal has steadily increased from 1800 to 2004. Burning coal was the leading cause of global fossil carbon emissions until around 1970, when the petroleum became the leading cause of global fossil carbon emissions. Petroleum use rose quickly after 1950.
Which of the following statements about biogeochemical cycles is true?
What is the purpose of a rain gauge?
Explain why a variety of instruments are needed to measure change in the climate system.
More than one instrument is needed to measure change in the climate system because its complexity. The climate system involves the interaction of the atmosphere, land masses, and bodies of water. Because there are a variety of factors that influence climate, a variety of instruments are needed to measure changes in the climate system.
What are some advantages of tracking changes in the climate system?
Tracking changes in the climate system can help forecast weather conditions. It can also help predict natural disasters, such as hurricanes. Another advantage of tracking changes in the climate system is the ability to determine human impact on the climate system.
What is the purpose of the radiosonde?
The Radiosonde is used to measure temperatures, humidity, and pressure of the upper atmosphere. It can take measurements at up to 30 km.
