TEKS 5.11 The students knows that certain past events affect present and future events. C. Identify past events that led to the formation of the Earth’s renewable, nonrenewable and inexhaustible resources.

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. Granite

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.

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 an inexhaustible resource. It can be replaced by the water cycle. D. Granite is an igneous rock which forms underground when magma cools and hardens.

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

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.

These answers are incorrect because: A.Inexhaustible resources can be used over and over again. They are renewed by the Earth’s natural cycles. Water and wind are examples. B. Renewable resources are reproduced at the same rate they are used. Forests are an example. C. Minerals are a nonrenewable resource but are used for buildings and roads rather than fuel.

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

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.

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 an inexhaustible resource? A. Water from the sprinkler B. Soil under the grass C. Fuel for the mower D. Grass and plants

Correct answer is “A” Water from the sprinkler Water from the sprinkler Water is an inexhaustible resource. The water cycle allows Earth’s limited supply of fresh water to be used over and over again.

These answers are incorrect because: B.Soil is a renewable resource. As rocks are weathered away, new soil is formed. C.Fuel (gasoline) used in a mower is a nonrenewable resource. It can’t be replaced once it is used up. D. Grass and plants are renewable. As plants die and decay, new plants grow in their place.
