(3) This states (1) that life has greatly altered the environment globally for more than 3 billion years and continues to do so; and (2) that these changes benefit life (increase its persistence).

Steady state

Chapter 16, Results when the rocks that are under stress from internal earth processes rupture, mostly at depths of 10 to 15 km along faults. Releases vast amounts of energy!! Images (http://www.dimensionsguide.com/what-is-the-biggest-earthquake/) [K.E]
Volcanic Eruption
Chapter 16, Volcanoes are the result of extrusion at the surfaces of molten rock (magma). Volcanic eruptions may be explosive and violent or they may be less energetic lava flows. Volcanoes generally occur at boundaries between tectonic plates, where active geologic processes favor the melting of rocks and the upward movement of magma. Some volcanoes also occur in more central parts of tectonic plates where hot spots deep below heat the rocks above i.e. Yellowstone or the Hawaiian Islands! [K.E]
Chapter 16, Landslide is a general term for the down slope movement of soil and rock. Landslides occur when the driving forces that tend to movie soil, rock, vegetation, houses, and other materials down a slope exceed the resisting forces that hold the slope in place. The resisting forces are produced by the strength of the material on slopes and result of from interlocking rains of rock or soil, natural cementing material in rock and soil, or plant roots that bind the slip materials together and resist movement. Weak rocks on steep slopes provide for the combination of large driving forces and weak resisting forces that favors development of landslides. The dominant driving force of slopes is the weight of slope materials influenced by the force of gravity. The steeper the slope and the heavier the slope materials, the greater the driving forces. Human processes that add to or increase the slope angle (how steep it is) increase the drive forces. Resisting forces may be reduced by increasing the amount of water on or in a slope, or by removing vegetation that reduces the root strength of the soil or rock. [K.E]
Chapter 16, A hurricane is a tropical storm with circulating winds in excess of 120 km (74 mi) that move across warm ocean waters of the tropics. Hurricanes gather and release huge quantities of energy as water is transformed from liquid in the ocean to vapor in the storm. [K.E]
Chapter 16, A tsunami is a series of large ocean waves produced after the ocean water is suddenly disturbed vertically by processes such as earthquakes, volcanic eruptions, submarine landslides, or the impact of an asteroid or comet. Over 80% of all tsunamis are produced by earthquakes. [K.E]
Chapter 16, A wildfire is a rapid, self-sustaining, biochemical oxidation process that releases light, heat, carbon dioxide and other gases and particulates into the atmosphere. Fuel, plant material, is rapidly consumed during wildfires, helping maintain a balance between plant productivity and decomposition in ecosystems. The primary cause of periodic wildfire is vegetation. When microbes in the environment are not able to decompose plants fast enough to balance the carbon cycle, fire is necessary to achieve a long-term balance. [K.E]
Chapter 16, A tornado is a funnel-shaped cloud of violently rotating wind that extends downward from large cells of thunderstorms to the surface of Earth. Severe thunderstorms may occur when a cold air mass collides with a warmer one. Water vapor in the warmer part of the atmosphere is forced upward where it cools and produces precipitation. As more warm air is drawing in, the storm clouds grow higher and thu7nderstorm activity increase in intensity, forming lines of storm activity (squall lines hundreds of kilometers long or large cells of updraft called super cells). Tornadoes in the U.S. are concentrated in the Plains states between the Rocky and Appalachian mountains, where severe thunderstorms generally are more common. Some parts of this region have been called "tornado alley." [K.E]
Biogeochemical cycle
Ch. 5 The complete path a chemical takes through the four major types of reservoirs. AB

Carbon cycle
Ch. 5 Carbon appears in the atmosphere mostly as CO2 and CH4, but also in some other gases. The uptake of CO2 from the atmosphere through photosynthetic processes plants do is the primary flux from the atmosphere to the biosphere. The carbon compounds in the plants are spread throughout the biosphere through consumption. when an organism dies, the carbon enters the lithosphere through the decomposition of dead tissue. The sequestered carbon can, over an extremely long period of time, become a usable fossil fuel that is extracted and burned, releasing the carbon back into the atmosphere. Atmospheric carbon can also enter the hydrosphere by dissolving into the ocean, creating carbonic acid, carbonate, and bicarbonate. The carbon in the hydrosphere is used by marine organisms to create shells, bones, and tissue. When they die, they sink to the bottom of the sea where their tissues decompose and release carbon back into the hydrosphere and their bones and shells enter the lithosphere. AB

Carbon-silicate cycle
Ch. 5 Atmospheric carbon dissolves in water making carbonic acid, which falls as rain. The acidic rainwater does the weathering of silicate-rich surface rock, which creates carbonate and bicarbonate ions. These ions are used by marine organisms to create shells that eventually sink to the bottom and re-enter the lithosphere. The sedimentary rock eventually enters a subduction zone where it becomes magma that releases CO2 into the atmosphere through volcanic activity. This creates a flux between the atmosphere and lithosphere. AB

Chemical reaction
Ch. 5 A reaction between two or more reactants that results in chemically different products. AB

Ch. 5 The process when nitrogen compounds are broken down and released back into the atmosphere as Nitrogen gas. AB

Drainage basin
Ch. 5 The area that is the source of surface runoff for a stream or river AB

Geologic cycle
Ch. 5 The processes responsible for the formation and change of Earth materials, like the tectonic, hydrologic, rock, and biogeochemical cycles. AB

Hydrologic cycle
Ch. 5 Driven by the heat from the sun. It is the transfer of water from the oceans to the atmosphere to the land and back to the ocean. Water evaporates from the ocean into the atmosphere, forming clouds. When the clouds become dense enough, it rains onto the land, where it enters lakes, rivers, streams, and groundwater. Groundwater can be used by plants, and surface water can be drunk by animals and humans. Water transpires out of plant leaves into the atmosphere, and surface water then returns to the ocean. AB

Limiting factor
Ch. 5 A chemical that is not available at the right time, amount, or concentration. AB

Ch. 5 A flood is the inundation of an area by water. Floods are produced by intense rainstorms, melting of snow, storm surge from a hurricane, tsunami, and rupture of flood protection structures. Flooding occurs as water is transported across the surface of land or inundates a particular location. These floods can cause erosion among riverbeds. AB

Heat Wave
days or weeks in which temperature rises a lot (Some think that recent ones have been caused by global warming) AB

A period of months, or more commonly years, of unusually dry weather constitutes a drought. This phenomenon is related to natural cycles of wet years that alternate with series of dry years. The reasons for the cycles of drought are not well understood, but are thought to be related to the heating of ocean waters and the moving of major air masses. Droughts in California, for example, are thought to be due to the decadal shift in high-pressure zones that form in the central Pacific Ocean and to the jet stream that allows winter storms to extend south or remain further. Dry years in southern California occur when storm tracks remain north of central California for several years. Prolonged droughts in the Midwestern states, such as the Dust Bowl that developed that developed in the 1930s in Kansas and other nearby regions, are associated with gigantic dust storms that commonly occur is desert regions. Droughts in central Africa have been devastating to human populations.

Discuss the La Conchita Landslide of 2005
In 2005, in La Conchita California, a landslide killed ten people and destroyed 30 homes. This was a partial reactivation of a landslide that occurred in 1995. There was high rainfall in 2005, but no one recognized the risk for a landslide. They should have realized that not only was there a risk that year, but there was always a risk and no one should've been living there. La Conchita had been having landslides for 100 years, and was built on 15m of older landslide departments. It was later discovered that all these landslides were part of a major prehistoric landslide.
