WorksheetsUnit 4 review:' fossil fuels and land formations
Total questions: 12
Worksheet time: 24mins
Which list contains ONLY processes the must occur in order for fossil fuels to form?
Formation of faults, burial, glacier formation
Organism growth, burial, volcanic eruptions
Organism growth, burial, compaction
Erosion, burial, earthquakes
Which diagram models the process of COMPACTION leading to the formation of sedimentary rock?
Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?
Rocks are broken into smaller pieces that remain in the same location
Pressure compacts layers of sediment and turns them into rock
Pieces of rock or soil are carried from one place to another
Sediment grains fall to the bottom of a lake to form sedimentary layers
Fossil fuels formed over long periods of time after particles in water settled to the sea floor and formed marine mud. What kinds of particles needed to be present in the marine mud in order for fossil fuels to form?
Mostly sand and a few bits of wood
Mostly decaying organisms
Mostly lava and a few sedimentary rocks
mostly metal minerals
All of these are related to the formation of oil or natural gas EXCEPT-
Decomposed animals
decayed plants
sedimentary rocks
active volcanoes
Which of the following best explains how these layers can become rock over many years?
Sand in the sediment melts and turns into rock
The weight of the water compacts the sediment into rock
Changing water temperatures turn sand in the sediment into rock
Pollution caused by humans turns the sediment into rock
Monahans sandhills state park in Texas has almost 4,000 acres of sand dunes. Some of the dunes are as tall as a 6-story building. The duns in the park are formed by-
rainstorms
tornadoes
earthquakes
strong winds
The Rio Grande valley is located at the southern tip of Texas at the end of a long river known as the Rio Grande. How did the delta at eh end of the Rio Grande form?
Sand and mud from the Gulf of Mexico were washed ashore by tsunamis
The river cut through the solid bedrock of the valley
The river deposited large amounts of sediment from the land erosion
Hurricanes pushed soil and debris from the Gulf of Mexico on the the land
Which of these describes how this canyon was most likely formed?
Floods eroded the sandstone away from the canyon walls
Glaciers eroded the canyon rock as they melted and moved
Ice wedged into cracks in the rock and weathered the canyon walls
Wind blew large rocks that smashed against the canyon walls
Which of the following statements best explains how petroleum is formed?
Over millions of years, the fossils of dinosaurs decayed and slowly turned into oil.
Oil comes from ancient mud and soil that has been heated in the Earth's crust from millions of years.
Oil comes from the heat and pressure that has been applied to dead microscopic plant and ocean animals for millions of years.
Large machines extract ancient water from the Earth's crust, and scientist add chemicals that change the water to oil.
Which type of landform most likely results from the movement of a glacier?
A sharp V shape valley
A wide and deep canyon
A curved path like a river
A curved U shape valley
How do river deltas change over time?
More and more sediments build up around the delta. The river develops more branches.
Water erosion continues. The ocean wears away the land, and the coastline recedes.
Water erosion continues. Smaller river branches disappear, and the main branch becomes deeper.
Fewer sediments are deposited into the river system. The river valley dries up, and vegetation dies out.
