It spreads at the rate of 1 to 10 centimeters per year.Why would it be useful for scientists to use a model in order to study the spreading of the Atlantic Ocean's floor? The process occurred in the past, but it is no longer occurringThe spreading of the ocean is too abstract a concept for people to visualize without a model.It would take several years to collect the data about the process first hand.The ocean is spreading on such a large scale that it cannot be measured with normal tools.

Instead, many volcanologists use models to study volcanic eruptions. What is the most likely reason why volcanologists often rely on models to study volcanic eruptions? Volcanic eruptions take too long to be able to be observed in their entirety.Volcanic eruptions are rare occurrences so it is difficult to see them.Volcanic eruptions are too large to be able to see with the naked eye.Volcanic eruptions are very dangerous events.Wednesday, December 12, 20123. In the 1990s, scientists used satellite images to locate a giant asteroid crater in the Gulf of Mexico. The crater, named Chicxulub, was formed about 65 million years ago.After discovering the crater, scientists used computer programs to model the effects of the asteroid's impact on the planet.Why did scientists have to use a model in order to study the asteroid's effects? The impact of an asteroid is too abstract a concept for people to visualize without a model.It would take several years to collect data about the event first hand.The event occurred too long ago to study directly.The event occurred too slowly to be studied in real time.Thursday, December 13, 20124. Sariah's science teacher asked everyone in the class to bring a model of the park near their school so that they could add labels to them in class. To which kind of model would it be easiest to add labels? a scale drawing of a cross-section of the parka scale drawing, looking down on the parka scale-model diorama made of dirt and sticksa scale-model sculpture out of clayFriday, December 14, 2012 5. Many companies are making permanent coffee filters like the one below.How is this an improvement on the traditional, paper coffee filters? They are less wasteful and more cost effective because they last longer.A permanent filter is more expensive than a traditional filter.The coffee brewed using permanent filters does not taste as good.They contain plastic which does not break down as easily as paper. ................
