Earth Science Final Review

Front

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

Back

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.

Front

Which sentence best describes the Earth system?

Back

It is a dynamic system with parts that interact with each other over short and long periods of time.

Front

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.

Back

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.

Front

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 shows tornado data for Alabama over a number of years. Which statement could the meteorologist use to support the claim?

Back

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

Front

System

Back

Contains components of matter and energy and exhibits interactions between the components.

Front

The sun and Earth form a system in space in which different factors interact to drive processes. Which answer correctly matches the driving factor of each process?

Back

Gravity drives the motion of Earth's orbit and heat drives the formation of clouds

Front

Why is it important for scientists to study multiple systems on Earth at the same time instead of studying them separately?

Back

They can observe how parts of the different systems affect each other.

Front

Rainwater washing away sediment on a hillside is primarily an interaction between which of Earth’s spheres?

Back

Hydrosphere and geosphere

Front

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

Back

It flows from lines that are closer together to lines that are farther apart.

Front

Which of these events is an example of how the water cycle includes interactions with the biosphere? Rainwater falls on a grassy slope, Strong waves wash away sand at a beach, Ocean water evaporates and forms clouds, Sediment on a mountainside is washed away.

Back

Rainwater falls on a grassy slope
