Praxis II 0014 Earth Processes and History
| Question | Answer |
|---|---|
| Plant Process | pulls water (hydrosphere) and nutrients from the soil (lithosphere) and release oxygen and water vapor into the air (atmosphere) |
| Human Process | built glen canyon using rock material (lithosphere) to control a lake (hydrosphere) as the water evaporates, it moves into the air (atmosphere) |
| Heat | Solar Energy and Radioactivity; influences the Earth more than any other process in the universe |
| Solar Energy | (the sun) the Earth is on an axis , and the sun hits the surface at varying angles causing the major climates of the planet |
| Radioactivity | (earth's core) responsible for the plate tectonics, most volcanoes, and earthquakes, which are located near plate boundaries |
| Weathering | the process of changing structures through the effects of the wind, water, ice, sun, and gravity |
| Erosion | the process of moving the weathered materials (rivers, wind) |
| Rock cycle | all rocks come from the mantle (except limestone) |
| Igneous | Forms when magma cools (granite, pumice) |
| Sedimentary | Forms when layers of sediments are compressed (sandstones, limestone, coal, shale) |
| Metamorphic | Forms through the transformation of igneous and sedimentary rocks through heat and pressure (marble, slate, quartzite) |
| Earth's Age | 5 billion years |
| Percent of the Earth covered in water | 71% |
| Percent of the Earth's ocean water | 97% |
| Precambian Eon | 4.6 billion years ago, the time before the rise of life-forms |
| Paleozic era | 570-286 million years ago- Trillobites, shells, mollusks, brachiopods, echinoderms, rise of first vertebrates, rise of land plants, rise of amphibians, insects, seed plants, and trees, and reptiles |
| Mesozoic era | 245-144 million years ago: the rise of mammals and dinosaurs, the rise of birds, the extinction of dinosaurs, and the rise of flowering plants |
| Centzoic era | 66 million years to present: the rise of primates, the rise of horses, the rise of hominid and modern man |
