Q2 Sequence 3
What are the Surface Events that result in changes to the Earth’s System?
| Term | Definition |
|---|---|
| Weathering | The natural process of rocks and soil material being broken down or deconstructed. |
| Erosion | The natural process of rock and soil material being moved from one place to another. |
| Deposition | The natural process of rock and soil material being deposited or laid down in a new location and eventually constructed into new rock or landform. |
| Mechanical (physical) Weathering | The process through which large rocks are broken into increasingly smaller pieces due to the motion or action of matter! |
| Chemical Weathering | The process through which larger rocks are broken down and something new is produced due to chemical reactions with chemicals released by organisms or other matter. |
| Landforms | A natural feature of the earth's surface. |
| Coastlines | The boundary that forms between land and water. |
| Dunes | A mound or ridge of sand or other loose sediment formed by the wind, especially on the sea coast or in a desert. |
| Glaciers | A slowly moving mass of ice formed by the accumulation and compaction of snow on mountains. |
| Deltas | A landform shaped like a triangle that forms at the mouth of a river where it empties into a larger body of water. Deltas are created by the deposition of sediment carried by the river, which slows down and spreads out at a larger body of water. |
| Lakes | A large body of water surrounded by land. |
| Rock Cycle | A continuous, natural process that describes how rocks of all types (igneous, sedimentary, and metamorphic) are formed, broken down, and changed over immense spans of time. |
| Compaction and cementation | The natural process of sediment and soil material that was deposited, now being squeezed together over time due to gravity an/or pressure from new rock above it and eventually being constructed into new rock or landforms. |
| Wind as an Agent | Slowly breaks down rocks overtime into smaller pieces, can carry these pieces away great distances, and eventually dropping these pieces in new locations. |
| Ice as an Agent | Breaks down rocks very slowly. Glaciers break down rock when they move over them and eventually drop off the pieces in new locations when the glacier slows down or stops moving. |
| Water as an Agent | Tear rock down by breaking it down into smaller pieces. water can also move rock that has been broken by carrying it with waves or currents and eventually drop the rock in new locations. |
| Gravity as an Agent | Cause rocks to fall from high places to low places and often break into smaller pieces in the process. |
| Plants as an Agent | Having powerful roots that help them get water and nutrients from the soil, these roots break through rocks in search of nutrients. they can also hold onto rocks and sediment preventing it from being carried away. |
| Lichens as an Agent | Plant like organisms that grow on rocks that as they grow they release acids that chemically weather rocks away. |
| Animals as an Agent | They use rocks often for a source of shelter, they will break up rocks as they search for home to make. |
| Temperature as an Agent | The process of freezing and thawing can break down rocks. Trapped water freezing in the cracks of rock is just an example. |
| Chemicals as an Agent | Chemical compounds that are located within the air and water that interact with rocks, creating holes and eventually breaking down rocks. Example acid rain. |
| Constructive Process | The building up of material (sand, rocks, silt, clay, etc.) to create a new landform. |
| Destructive Process | The breaking down of materials (sand, rock, silt clay, etc.) from existing landforms. |
| Abrasion | A mechanical process of weathering rock due to repeated exposure and rubbing motion of an agent such as water or wind. |
| Frost Wedging | When water fills in the cracks of rocks and freezes. This process repeatedly causes the rock to break apart in a process called freeze-thaw. |
| Controlled Experiment | A scientific test in which one of the factors are changed at a time, while others are kept constant. |
| Independent Variable | The variable that is changed in an experiment. You can only have ONE of these per experiment. |
| Dependent Variable | Variables that are affected by the change, they are measured. The outcome depends on the independent variable. |
| D R Y M I X | Dependent Manipulated Responding Independent Y-axis X-axis |
| Control Group | An item or group that does NOT receive the independent/tested variable. |
| Control Variable | Variables that are kept the same. |
| Repetition | Conducting multiple trials of measurements or observations in a scientific investigation. YOU conduct the investigation. |
| Replication | The reproduction of a scientific investigation by another person or group to ensure the accuracy of an experiment. OTHERS conduct the investigation. |
