1. TEKS 5.7A Explore the processes that led to the formation of sedimentary rocks and fossil fuels. TEKS 4.7C Identify and classify Earth’s renewable resources, including air, plants, water, and animals; and nonrenewable resources, including coal, oil, and natural gas; and the importance of conversation

2. 1. The chart shows some natural resources. Which of these would complete the column of Nonrenewable Resources? Nonrenewable Resources Renewable Resources coallumber petroleumsoil ???grass/plants A. Wind B. Water C. Natural gas D. Oxygen

3. Correct answer is “C” Natural gas The three main types of fossil fuels are: coal, petroleum, and natural gas. They are nonrenewable resources because they take millions of years to form underground. The three main types of fossil fuels are: coal, petroleum, and natural gas. They are nonrenewable resources because they take millions of years to form underground.

4. These answers are incorrect because… A.Wind is an inexhaustible resource. It is so vast that it cannot be used up by human activity. B. Water is a renewable resource. It can be replaced by the water cycle. D. Oxygen is a renewable resource. It is created and released into the air by producers.

5. 2.Look at the following pictures. All three are powered by what type of natural resource? A. Manmade resources B. Renewable resources C. Internet resources D. Nonrenewable resources

6. Correct answer is “D” Nonrenewable resources Petroleum is the world’s most widely used fossil fuel. It is used mainly for transportation. Natural gas is usually found with petroleum and is used mostly for heating and cooking. Both are fossil fuels and are nonrenewable resources.

7. These answers are incorrect because: A.Manmade resources are made from natural resources. B. Renewable resources are reproduced at about the same rate they are used. Forests are an example. C. Internet resources provide information and services, not fuel.

8. 3.Scientists were asked to explore a region in search of coal. Using the chart identify which region they should explore first? REGION DESCRIPTION OF REGION 1 Slopes of an active volcano 2 Dry river bed 3 Area that was once a swamp 4 Desert with sand dunes

9. Correct answer is Region 3, the area that was once a swamp. Coal is the most common fossil fuel. Much of the coal used today comes from plants that lived in swamps millions of years ago. As the plants died, they sank to the bottom of the swamps. Mud and other sediments covered their remains; with pressure and time these changed into coal. Coal is the most common fossil fuel.

10. 4. The picture below shows a woman who has just finished mowing her lawn. Look at the picture carefully. Which resource in the front yard is NOT a renewable resource? A. Water from the sprinkler B. Soil under the grass C. Fuel for the mower D. Grass and plants

11. Correct answer is “C” Fuel for the mower Fuel (gasoline) used in a mower is a nonrenewable resource. It can’t be replaced once it is used up. Fuel (gasoline) used in a mower is a nonrenewable resource. It can’t be replaced once it is used up.

12. These answers are incorrect because: A.Water is a renewable resource. The water cycle allows Earth’s limited supply of fresh water to be used over and over again. B. Soil is a renewable resource. As rocks are weathered away, new soil is formed. D. Grass and plants are renewable. As plants die and decay, new plants grow in their place.
