|
|
||||
|---|---|---|---|---|---|
| show | examines the structure and function of the earth. also extends studies into space and the universe. important because it directly relates to human actions and behaviors
🗑
|
||||
| show | atmosphere (air), lithosphere (land), hydrosphere (water), biosphere (life)
🗑
|
||||
| show | Exosphere (300-600 -6,000 miles); thermosphere (includes ionosphere) (265,000-285,000 feet to 400+ miles); mesosphere (160,00- feet to about 285,000); stratosphere (23,000-60,000 to about 160,000 feet); troposhere (23,000-60,000 feet)
🗑
|
||||
| 4 layers of Earth | show 🗑
|
||||
| crust | show 🗑
|
||||
| show | 1,800 miles thick, plasticity (ability of solid to flow), circulating currents, causing the plates to move
🗑
|
||||
| show | 1,300 miles thick, viscous liquid, the Earth's magnetic field originates here
🗑
|
||||
| show | 800 miles to the center of the earth, a solid
🗑
|
||||
| plate tectonics | show 🗑
|
||||
| show | convergent (collision), transform (rubbing), divergent (separating)
🗑
|
||||
| show | collision, results in mountains, volcanoes, ridges, recycling of crust
🗑
|
||||
| transform plates | show 🗑
|
||||
| divergent plates | show 🗑
|
||||
| show | plants, humans, heat (solar energy and radioactivity), weathering, erosion, rock cycle
🗑
|
||||
| plants | show 🗑
|
||||
| humans | show 🗑
|
||||
| show | influences the Earth more than any other process in the universe. There are 2 sources (solar energy and radioactivity)
🗑
|
||||
| solar energy | show 🗑
|
||||
| show | Earth's core - radioactivity is responsible for plate tectonics, most volcanoes, and earthquakes which are located near plate boundaries. Radioactivity makes mountains, valleys, ocean basins, lake beds, islands, trenches and most other land forms
🗑
|
||||
| show | the process of changing structures through the effects of wind, water, ice, sun and gravity
🗑
|
||||
| erosion | show 🗑
|
||||
| show | all rocks come from the mantle (except limestone)
🗑
|
||||
| show | igneous, sedimentary, metamorphic
🗑
|
||||
| show | forms when magma cools (ex. granite, pumice)
🗑
|
||||
| show | forms when layers of sediments are compressed (ex. sandstone, limestone, coal, shale)
🗑
|
||||
| metamorphic rock | show 🗑
|
||||
| weather cycle | show 🗑
|
||||
| show | heat energy (infrared radiation) from the sun that hits the Earth's surface is changed into head
🗑
|
||||
| Earth movement | show 🗑
|
||||
| show | a natural process in which water evaporates, condensates and precipitates (condensation-water vapor-precipitation-infiltration-evaporation-transpiration)
🗑
|
||||
| show | 5 million
🗑
|
||||
| % of earth covered with ocean | show 🗑
|
||||
| show | 97%
🗑
|
||||
| show | 2-5 cm
🗑
|
||||
| geological history | show 🗑
|
||||
| principle of uniformitarianism | show 🗑
|
||||
| show | the oldest rocks and events are found at the bottom of formations, and the youngest are found at the top (the past is on the bottom)
🗑
|
||||
| eon | show 🗑
|
||||
| 2 major eons of Earth history | show 🗑
|
||||
| show | period of time from the formation of Earth (4.6 billion years ago) to the rise of life-forms (similar to present day life forms)
🗑
|
||||
| show | the rest of the time to present day. 3 eras are found within this eon - paleozoic, mesozoic, centzoic
🗑
|
||||
| Paleozoic Era | show 🗑
|
||||
| show | midle life, 245-144 million years ago; rise of mammals and dinosaurs, the rise of birds, the extinction of dinosaurs and the rise of flowering plants
🗑
|
||||
| show | late life, 66 million years ago to present; the rise of primates, horses, hominids and modern man
