- it is not troposphereWhat is one way that you could identify the troposphere? O It contains 21% oxygen. O It contains 28% nitrogen. O It contains 40% carbon. O It contains 60% helium. O It contains 32% sulfur.Outline three characteristics of Stratosphere and two benefits of the mentioned characteristics to man
- The formation of the __________ in the lower stratosphere was necessary for terrestrial life becuase it protected organisms from harsh UV light. (two words)Carbon is released from organisms as part of cellular respiration. If the organism lives on land, what part of the biosphere is the carbon released into? stratosphere hydrosphere atmosphere lithosphereChanges in the Air To assess the impact of human activity on the carbon dioxide level in Earth's atmosphere, it helps to take a long view. One useful data set comes from deep core samples of Antarctic ice. The oldest ice core that has been fully analyzed dates back a bit more than 400,000 years. Air bubbles trapped in the ice provide information about the gas content in Earth's atmosphere at the time the ice formed. Combining ice core data with more recent direct measurements of atmospheric carbon dioxideas in FIGURE 46.20can help scientists put current changes in the atmospheric carbon dioxide into historical perspective. FIGURE 46.20 Changes in atmospheric carbon dioxide levels (in parts per million). Direct measurements began in 1980. Earlier data are based on ice cores. 4. Was the rise in the carbon dioxide level between 1800 and 1975 larger or smaller than the rise between 1980 and 2013?

FIGURE 46.20 Changes in atmospheric carbon dioxide levels (in parts per million). Direct measurements began in 1980. Earlier data are based on ice cores. The industrial revolution occurred around 1800. What was the trend in carbon dioxide level in the 800 years prior to this event? What about in the 175 years after it?1Which of the following is NOT a consequence of global climate change? coral bleaching more ice at the North and South Poles increases in diseases such as malaria and dengue fever rising sea levels 2How do scientists determine the atmospheric levels of carbon dioxide that existed on Earth hundreds or thousands of years ago? They deduce it from the carbon dioxide content of fossil fuels. They measure it from bubbles of gas trapped in Antarctic ice cores. They estimate it from the numbers of carbon-based life forms that existed over time. They calculate carbon dioxide levels from the temperature records. Scientists do not know the atmospheric levels of carbon dioxide thousands of years ago. 3The two factors that are responsible for the climate of an area are: the number and size of different kinds of species the position of the area in relation to island chains the elevation of the area, and its tree cover the amount of rainfall and temperature. the…Temperature inversions occur when a layer of cold air prevents warm air from rising make pollution problems worse last only a few minutes to a few hours cause cool air near the earth's surface to expand and rise, carrying pollutants higher into the troposphere help prevent air pollution
- Which earth’s layer is the lithosphereWhy are deserts typically found at 30° N and S in latitude? Group of answer choices Hadley Cells cause dry air to descend at 30° N and S in latitude. Rain shadows are only found at 30° N and S in latitude. All deserts experience a continental climate, which are common at 30° N and S in latitude. Savannas are found at 30° N and S in latitude, not deserts.NO NEED EXPLANATIONS 1.The zone of the earth that is divided into rigid plates is the: a.atmosphere b.lithosphere c.tectosphere d.biosphere 2.
