- ACID RAIN Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid raiñ"can belcaused by the combustion of fossil tuels, erupting volcanges, or rotting vegetation that releases sulfur dioxide and nitrogen oxide into the atmosphere. When fossil fuels such as coal, gasoline, and fuel oils are burned, they emit oxides of sulfur, carbon, and nitrogen into the air. These oxides combine with moisture in the air to form sulfuric acid, carbonic acid, and nitric acid. The term "acid rain" is also applied to other forms of precipitation-snow, hail, sleet, and fog-that are similarly acidic. During the 20th century, acid rain was recognized as a leading threat to the Earth's environment. Most acid rain comes from fossil fuel emissions produced in the industrialized northern hemisphere--the United States, Canada, Asia, and most of Europe. Acid rain is devastating to all forms of life, but its effects are especially severe in freshwater habitats such as lakes, rivers, and…Which one of the following statements is false? Group of answer choices Water plays the main role in the increase in the mean global temperature referred to as global warming. Water does not cause global warming because the atmospheric lifetime of water vapor is short. The amount of energy absorbed when water evaporates is large due to its strong intermolecular forces. Water absorbs the greatest percentage of infrared radiation being emitted by the earth. The energy when released water condenses heats the atmosphere and fuels storms.Matter and Energy in Living Syst x AClasses coveryeducation.com/learn/techbook/units/aa398417-005b-4c8e-99bb-8e74d1815830/concep e Classroom :) Matter and Energy in Living Systems plore Activity 8 The one thing which is similar about it is we use the same gases wh. another similar fact about is nitrogen is the same for it.

- If half of a quantity of radioactive material decays in 1 year, in another 10 yearsAlbert Einstein’s equation for the conservation of matter and energy (E = mc2) predicts that if the mass of uranium to be split in a nuclear fission reaction were to double, then: the amount of energy released would be decreased to one-fourth the amount of energy released would be decreased to one-half the amount of energy released would be increased four-fold the amount of energy released would be increased two-fold the amount of energy released would remain the sameWhich of the following statements accurately describes water vapor? The liquid phase of water is water vapor Water vapor is the water's solid phase. Water vapor is water in its gaseous state All of the above The zone composed of air, water, and soil is referred to as Atmosphere Biosphere Hydrosphere Lithosphere 3.Do greenhouse gases serve any purpose on Earth? No, they merely block a portion of the Sun's rays. They do, in fact, keep the Earth warm. Yes, they do maintain all of the gases on our planet in place. No, they merely contribute to catastrophic climate change.
