A.1. The greenhouse effect is when the temperature rises because the sun's heat and light is trapped in the earth's atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is becausethe heat and light from the sun can get into the car, by going throughthe windows, but it can't get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere, but it can't get out. As a result,the temperature rises. The greenhouse effect makes the earth appropriate for people to live on. Without it, the earth would be freezingor on the other hand, it would be bu because the sun would be down. During the day, especially during the summer,it would be burning because the sun would be up with no atmosphere to filter it, so people, plants and ning hot. It would be freezing at night animals would be exposed to all the light and heat. Although the greenhouse effect makes the earth able to have people living on it, if there gets to be too many gases, the earth can get unusually warmer, and many plants, animals and people will die. Plants like corn wheat, and other vegetablesand fruits would not be able to take the heat. This would cause ys to have less food to eat, but it would also limit the food that animals have. With less food, like grass for the animals that we need to survive (like cows), we would even have less food. Gradually, people, plants, and animals would all die of hunger. Complete the statements by choosing the correct option given: (1x5-5) a. Greenhouse effect can best be described as 1. rise of temperature 2. trapping of certainamount of heat and light Pege- 3. trapping of heat in a car 4. allowing the sun through the window. b. The global temperature is rising as 1. more heat is coming on earth more gases are there in atmosphere 3. heat is unable to get out of earth 4. presence of too many gases blocks the heat from escaping. C. Greenhouse effect is essential for our existence as 1. it maintains a balance of heat and light 2. it maintains the cold tmperature 3. it maintains the sun's heat 4. it acts like a filter.d. We would havelessfoodto eat as 1. Crops will die of heat 2. there will be too many people to share 3. animals also would want their share 4. cows won't have anything to eat. e. Eventually everyone will die of hunger as 1. We are all parts of chain 2. We will not be able to take the heat 3. We would disturb the ecological circle 4. We would not be able to have food
