How is the following passage from a cause-and-effect essay organized?The greenhouse gas theory states that, in normal conditions, sunlight warms the earth during the day. Then, at night the earth cools down. However, over the years, gases such as carbon dioxide have been released into the atmosphere. Now, those gases trap the heat that the earth would have cast off before.by chronological ordersubject by subjectby order of importancepoint by point

Read the following passage:An increase in automobile use has led to increased demand for fuel. The extraction, processing, and delivery of fuel put harmful pollutants into the atmosphere. The fuel that is then consumed by engines creates carbon dioxide emissions. The carbon dioxide creates a greenhouse effect in the atmosphere. The gasses trap heat in Earth's atmosphere, leading to global warming.What is one way the author uses a cause-and-effect structure to support his purpose?A.By explaining the relationship between automobile emissions and global warmingB.By exploring the dangerous effects of air pollution on living thingsC.By explaining how gases trap heat in the Earth's atmosphere.D.By listing several examples of how people can get around without automobilesSUBMITarrow_backPREVIOUS

The four sentences (labelled 1, 2, 3 and 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer.1. Billions of years ago, shifts in atmospheric composition like the impact of photosynthetic life set precedents for major climatic changes.2. Sustained volcanic activity, driven by the movement of Earth's tectonic plates, can alter regional and global climates by modifying ocean currents and wind patterns.3. The Earth's climate evolves due to interactions between the atmosphere and various geological, chemical, biological, and geographical factors.4. Human beings significantly impact climate change by emitting greenhouse gases into the atmosphere; however, this is just one part of a complex equation.

The greenhouse effect:Question 1Select one:a.occurs when gases in the atmosphere direct the sun’s heat into the atmosphere.b.occurs when gases in the atmosphere reflect the sun’s heat back down to Earth’s surface.c.occurs when gases in the atmosphere direct extra heat out into the atmosphere.d.none of the above
