Matter and Energy in Earth's System

You have learned that convection currents form in the atmosphere as heat is absorbed.

What process is happening in portion "A" of the model?

• Conduction

• Radiation

A group of students receives an exciting assignment: to design a new model biosphere. According to the criteria and constraints for the project, the biosphere must replicate Earth’s spheres as closely as possible, and it must be able to support life—but it may not use any resources that are located beyond the boundaries of the model. The students design a model biosphere under a large clear plastic dome with doors and windows opening wide onto the surrounding land to let in the fresh air. Inside there are rocks, soil, a small saltwater lake, a freshwater pond, fish, mammals, birds, insects, and even two humans. The next step is to determine if the model is ready for construction and testing. Their teacher tells them that theirs is considered a failure because they did not fully meet the criteria and constraints of the project. Which change in the design of the model will fix the problem so that the model can go forward with testing?

• The scientists should remove all of the soil because a working biosphere should not include the geosphere.

• The doors and windows to the biosphere should be closed because a working biosphere must be a closed system.

• The scientists should remove the oxygen from the model because a working biosphere does not require an atmosphere

• Either the pond or the ocean should be removed because a working biosphere cannot have a hydrosphere with both fresh water and salt water.
