| Convection Currents | Any movement of matter that results from differences in density; may be vertical, circular, or cyclical |
| Weathering | The natural process by which atmospheric and environmental agents, such as wind, rain, and temperature changes, disintegrate and decompose rocks |
| Erosion | The process by which wind, water, ice, or gravity transports soil and sediment from one location to another |
| Deposition | The process in which material is laid down |
| Igneous Rock | Rock that forms when magma cools and solidifies |
| Sediment | Broken down pieces of rock fragments created from weathering |
| Sedimentary Rock | A rock that forms from compressed or cemented layers of sediment |
| Metamorphic Rock | A rock that forms from other rocks as a result of intense heat, pressure, or chemical processes |
| rock cycle | A series of processes on the surface and inside Earth that slowly changes rocks from one kind to another |
| deforestation | The removal of trees faster than forests can replace themselves. |
| Cementation & Compaction | Gluing together of sediment and rock with minerals aided by pressure to make sedimentary rocks |
| Urbanization | An increase in the percentage and in the number of people living in urban settlements. |
| Desertification | Degradation of land, especially in semiarid areas, primarily because of human actions like excessive crop planting, animal grazing, and tree cutting. |
| Desertification causes | loss of topsoil, increased soil salinity, damaged vegetation, regional climate change, decline in biodiversity |
| deforestation causes | commercial farming, tourism, grazing cattle |
| heat & pressure | These two forces work together to transform rocks deep inside Earth's crust to metamorphic rocks. |
| Outcome of Urbanization | flooding, habitat loss, and deforestation |
| Outcome of Deforestation | erosion, flooding, and droughts |
| Outcome of Desertification | wind erosion, loss of crops and cattle grazing areas |
