KTE #3 (note: this is one of Theresa's 2 KTE terms)

Key Term: fossil fuel

Fossil fuels are natural hydrocarbon energy sources, such as coal, oil, and natural gas.  They are formed over millions of years, from the decomposition of plant and animal materials under heat and pressure.  Figure 1 shows the process in which oil and natural gas formed during plate tectonic activity.  The energy stored in fossil fuels like coal originally came from the sun, and that energy is released when fossil fuels are burned.  Unfortunately, as fossil fuels are burned, they release carbon which mixes with the atmosphere’s oxygen, creating carbon dioxide, a greenhouse gas.  Scientists believe that extra greenhouse gasses can potentially induce climate change and affect the environment.   

Alternative fossil fuels are being investigated, such as bituminous sands and oil shale. These require extensive processing before they can be used, but countries such as Canada have large reserves of “tar sands”, which may allow them to make it more economical for them to produce energy this way.

More than 85% of the United States’ energy comes from the use of fossil fuels, including almost two-thirds of our electricity, and almost all of the fuel used for transportation (Figure 2).  Petroleum accounts for about 37% of the world's total energy consumption, followed by coal (25%) and natural gas (23%).  Figure 2 shows the increase and breakdown of energy consumption in the US over the last 200 years. 

Due to the length of time they take to be formed, fossil fuels are not renewable sources of energy.

Figure 1
In figure 1, as the diatoms died they fell to the sea floor (1). Here they were buried under sediment and other rock (2). The rock squeezed the diatoms and the energy in their bodies could not escape. The carbon eventually turned into oil under great pressure and heat. As the earth changed and moved and folded, pockets where oil and natural gas can be found were formed (3).

KTE #2

Key Term: Sedimentary Rocks

Sedimentary rocks formed

Clastic sedimentary rocks: sandstone, limestone, shale

Chemical sedimentary rocks: rock salt, limestone

Organic sedimentary rocks: coal

Shale rocks from SFSU. These were stuck on the ground next to a tree.

Key Term: Igneous Rocks

Igneous rocks are formed by magma solidifying. There are two ways that igneous rocks are formed. Volcanic rocks, also known as extrusive rocks are formed when volcanoes erupt, causing magma to rise above earth’s surface and when the lava flows and harden. Plutonic rocks, also known as intrusive rocks are formed below earth’s surface when magma is cool down and solidified underground.

Igneous rocks formed

Volcanic rocks: obsidian, pumice, basalt

Plutonic rocks: granite, gabbro, diorite

Granite art piece at SFSU. Key Term: Metamorphic Rocks

Metamorphic rocks are formed by rocks transforming from existing rocks through elevated temperature, pressure, or hot fluids. There are three ways that metamorphic rocks form. Regional metamorphic rocks are formed through the increase of temperature and pressure over regions. Contact metamorphic rocks are formed by lava or magma in contact with other rocks over small regions. Hydrothermal metamorphic rocks are formed when the interaction of hot fluids are circulated through the rocks.

Metamorphic rocks formed

Regional metamorphic rocks: marble, quartzite

Contact metamorphic rocks: hornfels, skarns, shale

Hydrothermal metamorphic rocks: basalt, chlorite
