Earth Space Honor End of Course Exam Review

Questions 14-272013

Benchmark SC.912.E.6.4: Analyze how specific geologic processes and features are expressed in Florida and elsewhere.

14. Explain how the process of erosion affects Florida beaches

each year.

The affects of wind and waves on beaches naturally erode the beaches. The waves move the sand into the ocean and the wind moves the sand to other locations.

15. What actions could we take to prevent the erosion of Florida’s shorelines?

Benchmark SC.912.E.6.4: Analyze how specific geologic processes and features are expressed in Florida and elsewhere.

Add Plants and vegetation to the seashore banks

-Reduce usage of beaches -Move sand from the ocean and place it back at the shoreline to improve sand dune stability

16: Understand the processes that create underground caves and Karst Topography in Florida.

Groundwater CHEMICALLY weathers away the bedrock including limestone

Benchmark SC.912.E.6.4: Analyze how specific geologic processes and features are expressed in Florida and elsewhere.

17: Understand the methods used to age the Earth and its parts.

The age of Earth is around 4.6 billion years old. This is based on evidence from radiometric age dating of meteorite material and matches the ages of the oldest-known terrestrial and lunar samples. The rocks were dated using measurements of lead in uranium-rich minerals .

Benchmark SC.912.E.6.4: Analyze how specific geologic processes and features are expressed in Florida and elsewhere.

18. Explain the processes that create and destroy Earth’s crustal material.

Benchmark SC.912.E.6.5: Describe the geologic development of the present day oceans and identify commonly found features.

Destroy-Subduction

Create-Volcanic lava that cools-Ocean floor spreading

19. Where would Earth’s crust be the oldest? The newest?

Benchmark SC.912.E.6.5: Describe the geologic development of the present day oceans and identify commonly found features.

19. Where would Earth’s crust be the oldest? The newest?

Benchmark SC.912.E.6.5: Describe the geologic development of the present day oceans and identify commonly found features.

Benchmark SC.912.E.6.1: Describe and differentiate the layers of the Earth and the interactions among them.

Question 20. Identify common features on the ocean floor.

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

21. What gases make up of our atmosphere?

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

22. Which of these gases are most important to living organisms? WHY?

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

23. What is the water cycle and what energy source drives the water cycle?

The Sun

drives the

water cycle.

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

24. What is the carbon cycle?

• The circulation of carbon between Earth and the atmosphere and back again.

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

25. Describe three ways in which carbon is added to the atmosphere.•Burning of fossil fuels•Respiration•Deforestation (cutting down trees)

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

26. Describe three ways in which carbon is removed from the atmosphere.

Dissolving in oceansPhotosynthesis Buried in Earth

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

27.What happens to atmospheric temperatures when carbon dioxide levels increase or decrease?

-

When more carbon is in the atmosphere, the global temperatures increase contributing to global warming. When carbon dioxide is removed, temperatures cool.

Benchmark SC.912.E.7.1: Analyze the movement of matter and energy through the different biogeochemical cycles, including water and carbon.

27.What happens to atmospheric temperatures when carbon dioxide levels increase or decrease?

Since carbon dioxide is a greenhouse gas, it helps to naturally warm the Earth through the greenhouse effect.

Increase in greenhouse gases causes an increase in atmospheric temperatures

Decrease in Greenhouses gases cause a decrease in atmospheric temperatures
