Earth Sci Ch 2 Unit
| Question | Answer |
|---|---|
| the biosphere includes all organisms on earth (T/F) | True |
| most of earth's water is salt water (T/F) | True |
| deep wells allowed scientists to believe that the outer core of earth is liquid (T/F) | False (earthquake waves0 |
| the lithosphere is so hot, rocks found there are melted and flow (T/F) | False (asthenosphere) |
| topography is used to describe the shape of a geographic area (T/F) | True |
| oceans cover roughly 90 percent of earth's surface (T/F) | False (70%) |
| earth's asthenosphere includes both parts of earth's mantle and crust (T/F) | False (lithosphere) |
| earth's magnetic field is produced because earth's inner core spins faster than the outer core (T/F) | True |
| mountains, plains, and plateaus are all landforms which can be found in the U.S. (T/F) | True |
| earth's magnetosphere is the outer part of the magnetic field that interacts with charged particles form the sun (T/F) | True |
| scientist believed the deeper into the geosphere | temperature and pressure both increase |
| a layer not found in earth's mantle | crust |
| term used to explain how high or low a landform is above or below sea level | elevation |
| earth's system that makes up all the living organisms found on earth | biosphere |
| the more dense an object | the stronger the gravitational force |
| what cannot be found on both earth's surface and ocean floor | peninsula |
| layer of earth that is most dense | inner core |
| where are the longest mountain rages located | near the centers of the oceans |
| glaciers are part of earth's | hydrosphere |
| example of a landform with a low relief and a high elevation | Ozark Plateau |
| happens to the force of gravity when the distance between two objects decreases | it increases |
| are part of earth's biosphere except | carbon dioxide |
| helped the newly formed earth become a sphere in shape | gravity |
| best explains why landforms are not permanent | landforms are shaped by erosion and uplift |
| when scientists believed our solar system was formed | 4.6 billion years |
| statement that's true | when earth was forming, the most dense materials collected together to for the core |
| not a way scientists have been able to study earth's interior | measuring earthquake waves as they travel through earth's surface |
| not a true statement about earth's magnetic field | its strength has remained the same throughout history |
| reason why plains are the best landforms for growing crops or grazing animals | the soil found in plains is often rich in deposits, which allows for plants to grow |
| what objects do the force of gravity pull together | all objects |
| example of a raised, flat area is | Colorado Plateau |
| the crust and upper mantle make up earth's | lithosphere |
| plates of the lithosphere float on the | asthenosphere |
| the alignment of iron minerals in rocks when they are formed reflects the fact that earth's ____________ has reversed itself several times in the past | magnetic field |
| scientists believe that differences in ____________ cause hot, plasticlike rock in the asthenosphere to rise toward earth's surface | density |
| earth's ___________ consists of all the living organisms on earth | biosphere |
| earth was once believed to be in the shape of a flat disk now scientists know earth is really shaped like a _______________ | sphere |
| was the force that helped change a nebula into our solar system | gravity |
| the layer of gases surrounding earth make up the | atmosphere |
| the crust and the rigid part of earth's mantle together make up the | lithosphere |
| the layer of earth that is most dense is the | inner core |
| mesas, canyons, plains, and hills are examples of __________ found on earth's surface | landforms |
| is a major characteristic used to differentiate between a plain and a plateau | elevation |
| the interior plains of the United States were formed when ___________ were deposited millions of years ago | sediments |
| the central part of earth is the | core |
| all organisms on earth and the environments in which they live | biosphere |
| the rigid outer shell of earth | lithosphere |
| the water in earth's oceans, seas, rivers, and glaciers | hydrosphere |
| the partially molten layer of earth's mantle | asthenosphere |
| the blanket of gases that surround earth | atmosphere |
| flat, raised areas of land | plateaus |
| largest layer of earth | mantle |
