(Multi-Select Question_
What cause and effect connections below best explains how fossil fuels are formed?
(Select 3 of 5 choices)
 a.
Don’t Select
 b.
Cause: Heat from Earth’s interior radiated to decayed organic matter.
Effect: This heat helped convert the organic matter into coal. oil, and/or natural gas.
 c.
Cause: Pressure from tectonic plate movement compressed organic matter
Effect: This pressure helped convert organic matter into fossil fuels.
 d.
Cause: Earth’s unstable orbit around the sun.
Effect: Glacial periods (ice ages) and Inter-glacial periods (warming times)
 e.
Cause: Sedimentary rock formations were laid down on decayed organic matter.
Effect: Pressure from these sedimentary rock layers helped form fossil fuels.

By studying rock formations and fossils, scientists can determine local and global climatic conditions of regions from millions of years ago. For example, the chart below shows the estimated annual rainfall for six different regions on the Eurasian continent 300 million years ago.

Crosscutting Concept: Cause and Effect
Science and Engineering Practice: Analyzing and Interpreting Data
Which of these six regions had the greatest potential for forming coal, and why is it unlikely that this region would have the same annual rainfall today?
a.
The taiga region combined with the tundra region were the areas most likely to form coal deposits due to tectonic forces. Furthermore, due to the water cycle and the rock cycle, these areas are most likely still forming great amounts of coal today.
b.
The rainforest region had the most precipitation and the greatest amount of plant life. Therefore, it would have more organic material that could eventually become coal. Due to tectonic plate movement, this area today is probably no longer a rainforest.
c.
The deciduous forest region had the highest precipitation volume and the most diverse ecosystems. So, it would have more organic material that could potentially be converted into coal over time. However, in modern times this area today probably does not receive the same amount of rainfall due to tectonic plate movement,
 

 6. 

Tectonic processes form mountains, valleys, plateaus, and basins. These geological features consist of various types of rock formations that may or may not store water. In the United States, the area with the best conditions for storing groundwater is found in the Great Plains.
mc006-1.jpg
An agricultural company in the United States wants to purchase new farm land to expand their crop yields. They do not want to rely on rainfall alone to water their crops.  Therefore, they hired a rock formation specialist (a geologist) and a water specialist (a hydrologist) to help them locate a high-volume source of groundwater so that they can irrigate their crops with water from an aquifer.
Which of the following areas should they target for exploration and why?
a.
They should begin their search in a low-lying area (an estuary) near the shore of the nearby Atlantic Ocean. Gravity pulls water down towards these low area.
b.
They should examine a nearby geological basin containing permeable rock formations because it has the highest probably of having a large aquifer. 
c.
They should locate a suitable dig site at a high-elevation area on a jagged mountain peak. Water flowing down the slopes is likely to form underground reservoirs.
 

 7. 

The map below shows the distribution of mineral and coal deposits throughout the United States. A large portion on the mining locations are concentrated around mountainous areas such as the Gold mines in the Sierra Nevada mountains in California, coal mines along the Appalachian mountain range in the eastern United States, and various mineral mines in and around the Rocky Mountains in the western United States.

Two Part Question:
Part One: What tectonic phenomena can be associated with these three mountain ranges?
Part Two: How would this phenomena help scientists and miners locate/access these deposits?
a.
Part One: Phenomena-Uplift
Part Two: Raising the deposits nearer the surface, make is easier to find/extract them.
b.
Part One: Phenomena-Evaporation
Part Two: As part of the water cycle, ocean water evaporates  to form clouds
c.
Part One: Phenomena-Convection Cycles
Part Two: Convection currents in the Earth moves mineral deposits towards the core.
 

 8. 

Coal, which comes mainly from decayed terrestrial plants, is the most abundant fossil fuel in the ground. Coal forms when large amounts of organic matter pile up and decay under anaerobic conditions. Over time as these deposits are subjected to pressure from overlying rock formations and/or bodies of water, they undergo changes resulting in the solid fossil fuel that we call coal.

By looking over the map above, what can your infer about the climatic conditions millions of years ago in the states along the Pacific Coast (California, Oregon, and Washington) contrasted with the climatic conditions of the coal-rich interior states including Missouri, Kansas, Illinois, Indiana, West Virginia, and Pennsylvania?
a.
Large oil  and mineral deposits have been discovered in these interior states. However, no oil or minerals have ever been found in the Pacific Coast states.
b.
Pacific Coast states received higher amounts of precipitation and sunlight which resulted in the formation of coal deposits. These interior states had less rainfall.
c.
These interior states received high levels of precipitation and had diverse and vibrant forest ecosystems. Pacific Coast states received less rain had less plant life.
 

 9. 

When geologists search for aquifers, mineral lodes, and/or fossil fuel deposits, they use their knowledge of tectonic processes to help them locate these underground natural resources.
mc009-1.jpg
What pair of cause and effect statements shown below best demonstrates a connection between tectonic plate movement, and the amount of  groundwater in a region?
a.
Cause: Convection currents move tectonic plates around the globe.
Effect: Sometimes plates collide, and this forms a convergent boundary.
b.
Cause: Great quantities of water evaporate from the oceans every day.
Effect: This water eventually falls back to the surface as rainfall.
c.
Cause: A continent is moved to the equator in the middle of an ocean
Effect: Frequent rainfall on the continent results in large amounts of groundwater
 

 10. 

Tectonic processes contribute to the formation and uneven distribution of fossil fuels such as coal, petroleum, and natural gas. Based upon our understanding of how fossil fuels form, we can determine the climatic conditions that were present in an area millions of years ago.

Middle East had the most favorable conditions. Asia-Pacific had the least favorable
b.
North America had the most favorable conditions. Africa had the least favorable
c.
