What geological feature is essential for a trap to accumulate petroleum and other fluids?  Faults within the rock formation   High porosity and permeability   The presence of water-bearing formations   A closure or seal preventing fluid migration

Write the scientific term:1. A gas that is produced during the formation of oil and trapped inpockets within rock layers below the earth's surface.(............................)2. A process uses pressured fluids to break layers of shale rocks andforce out the trapped natural gas, which can be collected andtransported(............................)Put (true) or (false):1. Natural gas is also known as methane gas. ( )2. Fracking fluids are good for underground water. ( )3. Methane gas is one of the greenhouse gases that are good for theenvironment.( )Give a reason for each of the following:a) Natural gas burns cleaner than coal, yet it is considered a pollutant. Why?......................................................................................................................................................................................................................................b) Humans use the fracking process.......................................................................................................................................................................................................................................Topic 6 (L1) Page 297 – 298

Shale is a relatively impermeable type of rock, while sandstone is permeable to water. In some areas, the ground is made of mostly sandstone with a layer of shale deep underground. Groundwater can seep into the layers of sandstone and be stored above the layers of shale. At a fault line, rock layers are often shifted, sometimes causing layers of shale to reach the surface.Based on this information, what conclusion can be made about groundwater? A. Plate movement creates groundwater reservoirs by breaking impermeable rock layers into permeable rock. B. Groundwater is most abundant near faults and least abundant in the middle of tectonic plates. C. Tectonic activity can cause the amount of groundwater to differ by changing the position of impermeable rock layers. D. Geologic processes increase the amount of groundwater over time by causing shale layers to sink deeper underground.

A region is home to a large amount of petroleum. Which best explains the past processes that occurred in the region, as indicated by the presence of petroleum? A. Past hydrothermal activity occurred in the region, causing the formation and deposition of petroleum. B. The region experienced past volcanic activity that trapped ash underground, leading to the formation of petroleum. C. Marine sediment was buried and compacted; over millions of years, petroleum was formed, trapped beneath Earth’s surface. D. Weathering in the mountains in the region formed sediments; the deposition and compaction of these sediments formed deposits of petroleum.
