Unit 3 Lesson 4&5 Landforms

A science class is planning to model how an earthquake suddenly changes the land. Which of these ways could the class use to best demonstrate an earthquake?

• use loose rocks and let them slide down a pan 
• use two stacks of cards and press them together
• use baking soda and vinegar to model flowing lava
• use clay to model a mountain with lava running down it 

A student wants to make a model of a natural event on Earth by showing how gravity and flowing water can suddenly affect loose rocks and soil. Which of the following events is the student modeling?

• glacier 
• volcano 
• landslide
• earthquake

Shaun wants to make a model of a volcano to show how lava flows out of the volcano. Which of the following would be the best first step for Shaun to get started on his model?

• Plan and draw a design. 
• Gather model materials.
• Make the volcano mountain. 
• Decide how to model the lava. 

Brayden makes a model of something in nature that shows how Earth's surface suddenly changes. Which of the following did Brayden most likely model?

• a sea arch
• melting glacial ice 
• a slipping fault line in Earth's crust
• rocks and sediments in a river delta 

Emmy puts some baking soda in a bottle. When she adds vinegar, the mixture bubbles and spills out of the bottle. What natural event does Emmy's model show?

• lava flowing from a volcano 
• the epicenter of an earthquake 
• loose rocks sliding during a landslide 
• the deposition of sediment at a moraine 

Chloe often tells her brother to turn off the lights in their home. She tells him it is important to conserve energy. Why is it important to conserve energy?

• Energy is very difficult to bring into the home. 
• Energy cannot be purchased in small amounts. 
• Energy most often comes from renewable resources. 
• Energy most often comes from nonrenewable resources. 

Air pollution is a common problem across the United States. It is often caused by burning fossil fuels. Which of these is a renewable source of energy that causes less air pollution than burning fossil fuels?

• oil 
• gas
• coal
• sunlight

A local energy station burns coal to produce electricity. Why is coal considered a resource that is limited in supply?

• Coal is a mineral resource. 
• Coal is a renewable resource. 
• It takes millions of years for coal to form. 
• It is difficult to mine coal from deep inside Earth. 

Which of the following best describes how people can conserve resources such as sand, aluminum, and wood?

• Recycle glass, cans and newspapers. 
• Ride a bicycle instead of riding in a car.
• Turn off the lights when you leave a room. 
• Use less water when washing dishes or brushing teeth. 

Which of the following natural resources does using the process shown above conserve?

• lumber 
• quarries 
• minerals 
• petroleum
