More acidic water can be harmful to many ocean creatures, such as certain shellfish and coral. (2016, March 21). Too much of these greenhouse gases can cause Earth's atmosphere to trap more and more heat. Warmer waters are a main cause of coral bleaching. As you might expect from the name, the greenhouse effect works … like a greenhouse! A greenhouse is a building with glass walls and a glass roof. That's because the glass walls of the greenhouse trap the Sun's heat. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average. <> In simplest terms, "greenhouse gases" let sunlight through to the earth's surface while trapping "outbound" radiation. As you might expect from the name, the greenhouse effect works … like a greenhouse! Credit: NASA/JPL-Caltech. Greenhouse Effect Worksheet Sample Answers Directions: Study the diagram below, and then answer the questions that follow. <> Human activities are changing Earth's natural greenhouse effect. 2 0 obj (correct) c) Gases in the ozone layer absorb heat from the Sun. At nighttime, it's colder outside, but the greenhouse stays pretty warm inside. The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. Its glass walls trap the Sun's heat, which keeps plants inside the greenhouse warm — even on cold nights. Gases in the atmosphere, such as carbon dioxide, trap heat just like the glass roof of a greenhouse. endobj Credit: NASA/JPL-Caltech. Just like a glass greenhouse, Earth's greenhouse is also full of plants! 1 0 obj All plants — from giant trees to tiny phytoplankton in the ocean — take in carbon dioxide and give off oxygen. At night, Earth's surface cools, releasing heat back into the air. <>>> But some of the heat is trapped by the greenhouse gases in the atmosphere. Tags: Question 4. What is the major cause of the greenhouse effect? Earth's atmosphere traps some of the Sun's heat, preventing it from escaping back into space at night. The cooling of Earth due to air pollution. answer choices. The warming of a planet due to trapped radiation. Source: NASA. In the daytime, sunlight shines into the greenhouse and warms the plants and air inside. In the daytime, sunlight shines into the greenhouse and warms the plants and air inside. Unfortunately, the increased carbon dioxide in the ocean changes the water, making it more acidic. endobj Watch this video to learn about the greenhouse effect! The greenhouse effect works much the same way on Earth. These heat-trapping gases are called greenhouse gases. It refers to the amount of carbon dioxide and other carbon compounds emitted by A main cause of coral bleaching is warming oceans. The heating of a solid, such as a rock.
