Does Earth represent an open environmental system or a closed environmental system?

• Earth is a closed environmental system because energy can enter or leave the system but no significant amount of matter can enter or leave the system.

• Earth is a closed environmental system because no significant amount of energy or matter can enter or leave the system.

• Earth is an open environmental system because energy can enter or leave the system even though no significant amount of matter can enter or leave the system.

Which of these is an example of different scales in system interactions?

• A drought in an area causes farmers to need to irrigate their fields.

• A decreased amount of rain results in decreased crop heights in a backyard garden, leading to smaller produce

• The global atmosphere is warmer one winter, leading to a decreased snow pack in a mountain region, leading to a decreased water level of a lake in the region in the spring.

A meteorologist claims that the unusually warm water in the Pacific Ocean during an El Niño year affects the number of tornadoes in Alabama. El Niño events occur approximately every 2 to 7 years. The graph show tornado data for Alabama over a number of years. Which statement could the meteorologist use to support the claim?

• There are fewer tornadoes than average in years there is no documented El Niño event.

• There was a documented El Niño in 1982-1983, and the number of tornadoes was above the average the next few years.

• There was a greater-than-average number of tornadoes in 1972 and 1982, so those must have been greater El Niño years.

How can you determine which way a river is flowing on a topographic map?

• It flows from lines that are farther apart to lines that are closer

Which of these statements correctly describes a benefit of ozone to people?

• It clears harmful pollutants from the air

• It enhances the skin’s production of vitamin D

• It decreases the chance of developing skin cancer

• It decreases the probability of developing respiratory problems

Which statement describes the classification of water as a mineral?

• It is a mineral only as a solid because it has a definite crystalline structure.

• It is a mineral only as a liquid because its high polarity allows many substances to dissolve in it.

• It is a mineral only as a gas because it can condense back to a liquid at temperatures found on Earth.

The rock cycle is a system with inputs and outputs. Which of these is an OUTPUT of a rock cycle process?

• Erosion of igneous rock

• Melting of metamorphic rock

• Newly formed metamorphic rock

• Heat that melts igneous rock
