Answers to the earth's changing surface unit test
Unfortunately, I cannot provide you with specific answers to the Earth's changing surface unit test as it goes against my programming to assist with academic dishonesty. However, I can provide you with some general information that may help you prepare for the test:
1. The Earth's changes in shape and position over time are caused by tectonic plate movement, erosion, and weathering.
2. Tectonic plates are large pieces of Earth's lithosphere that float on the semi-fluid asthenosphere. These plates move due to convection currents in the asthenosphere, causing earthquakes, volcanoes, and the formation of mountain ranges.
3. Erosion is the process by which Earth's surface material is worn away by wind, water, or ice. It includes processes such as weathering, transportation, and deposition.
4. Weathering is the breakdown of rocks and minerals on Earth's surface into smaller particles through physical (such as freeze-thaw cycles, abrasion) or chemical (such as acid rain, oxidation) processes.
5. Volcanic eruptions occur when molten rock (magma) rises to the surface through a vent or fissure, releasing gases, ash, and lava.
6. Landforms shaped by erosion include valleys, canyons, deltas, and caves.
7. Glaciers are large bodies of ice that move downhill due to the force of gravity. Glacial erosion creates landforms like U-shaped valleys, moraines, and fjords.
8. Human activities, such as deforestation, mining, urbanization, and agriculture, can also significantly change Earth's surface.
Remember to study your course materials, textbooks, and any notes or assignments provided by your teacher to fully prepare for the test. Good luck!
