SC.7. N.1.5

A geologist creates a model that shows the movements of the tectonic plates of Earth’s surface. They want to use this model to understand the concept of how a mountain is formed. Which of the following describes what the benefits are from this model?

• It explains in detail how mountains are formed

• It speeds up a process that takes millions of years

• It shows all the plates in their correct layout

• It speeds up a process that takes millions of years

SC.7. N.1.5

A group of scientists has been asked to conduct a study on how an oil spill will affect the surrounding sea life. The scientists decide that the best way to complete the study is to create a model.  Which of the following is the most likely reason that the scientists will use a model instead of creating an actual oil spill study?

• They can study the effects of an oil spill without harming surrounding sea life

• They can use different species that the plants and animals found in the real ecosystem

• They expect the oil spill in their model to have a much greater effect than an oil spill in the natural environment

• They think using a model will provide them with more accurate results

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. Why is the energy from the sun an important part of the water cycle?

• It provides energy so that the water vapor in the air can condense.

• It provides the energy needed for water to evaporate.

• It melts the polar ice caps providing more drinking water

• The sun does not have an effect on the water cycle
