5.7A Sedimentary and Fossil Fuels

The series of pictures shows the formation of a natural resource.
Which natural resource found in the region marked with an X is formed in this process?

• Igneous rock
• Coal
• Oil
• Soil

While hiking in a forest a girl found a fossil imbedded in a boulder. The fossil is shown.

According to the above information and image, what does the fossil tell us about the nature of the environment in the past?

• The area was once covered by water
• The area was once much cooler
• The area was once a higher elevation
• The area will soon be covered by water

An archeologist thinks that his dig site used to be a creek environment.
 
Refer to the information and images. Which of the fossils would help support this hypothesis?

• A and B
• A and D
• B and C
• A, B, and D

Which of the following is associated with the formation of sedimentary rock?

• Heat and pressure
• Compaction and Cementation
• Chemical change and Heat
• Melting and Pressure

Coal was produced in the earth over millions of years. Which of the following is NOT a step in the production of coal?

• Animals died and were covered by sediment
• Plants died and were covered by sediment
• Heat, pressure, and time change the peat (decayed plants) to lignite
• Time and pressure changes the dead plant to peat (decayed plants)

Certain prehistoric events led to the formation of oil. Which of the following was one of those events?

• Giant wind storms destroyed forests
• Icebergs melted at the North and South Poles
• Microscopic life in the sea died and was buried under sediments
• Heavy flooding soaked the Earth's crust

Rocks will break down into smaller pieces. What are those pieces called?

• Crust
• Fossils
• Plates
• Sediment

Over long periods of time, fossil fuels form deep underground. Which components are related to the formation of fossil fuels?

• Lave, sand, and decayed animals
• Decayed plants, lava, minerals
• Decayed plants and animals and water from the ocean
• Decayed plants and animals and sedimentary rocks

Which of the following statements describes the first step in the formation of sedimentary rocks?

• Overlying pressure from rocks and soil reduces the size or volume of sediments
• Weathered material is moved by wind, water, or ice
• Exposed rock and other surfaces are broken down by wind, water, ice, or other elements
• A  Weathered and eroded material is deposited by wind, water, or ice

Plant fossils are found in abundance within the sandstone of the Antarctic Peninsula. The diverse plant fossils found in the area tells us that past the environment of Antarctica was ―

• Rainy and cold in the past
• Warm and temperate in the past
• Hot and dry in the past
• Cold and windy in the past
