Rock Cycle Quiz
Notes for rock cycle quiz
| Question | Answer |
|---|---|
| states that layers of Earth that are younger will be deposited on top of the layers that are older, given normal conditions of deposition. | Law of Superposition |
| formed by magma and lava – can be found in Hawaii | Igneous rock |
| starts as one type and turns into something different – found deep in the Earth. | Metamorphic rock |
| sediment formed by weathering and erosion and deposited over time – found near rivers, beaches, and lakes | Sedimentary rock |
| naturally occurring, solid substance – found in Earth’s crust | Mineral |
| takes place as rocks are broken down into smaller pieces by the effects of weather (sediment) | Weathering |
| the process where water, ice, wind, or gravity moves fragments of rock and soil (sediment) and deposits them in a new place | Erosion |
| How does temperature and pressure change as you move toward the center of the earth? | The temperature and pressure increase |
| Earth's layer of solid rock that includes both dry land and ocean floor. Thinnest layer | Crust |
| Layer of earth that is solid hot rock | Mantle |
| Layer of earth made of iron and nickel | Core |
| Inner layer of crust that is thickest under mountains; forms continents; contains granite | Continental |
| Inner layer of cruse made of basalt | Oceanic |
| Uppermost part of the mantle made of solid rock | Lithosphere |
| Layer of mantle that is less ridged; solid but softer and can bent | Asthenosphere |
| Is the lower mantle soft or solid? | Solid |
| The layer of core that is liquid molten metal; controls magnetic field | Outer Core |
| Layer of core that is a dense ball of solid metal | Inner Core |
| What type of heat transfer is the transfer of energy through space? | Radiation |
| Does radiation need direct contact? | No |
| What type of heat transfer is within material or between materials? | Conduction |
| Does conduction need direct contact? | Yes |
| What type of heat transfer is a movement of currents within a fluid? | Convection |
| Does convection require direct contact? | yes |
| Material heats up and rises and cools and sinks. Mantle rock is heated by the core and rises. It moves, cools, and sinks back toward the core. What is this describing? | The earth's convection currents |
| A theory proposed by Alfred Wegener that all the continents were once joined together in a single landmass and have since drifted apart. | Continental Drift |
| Three types of evidence that supported the continental drift theory | Land features, fossils, and climate |
| An underwater mountain range that extends into all oceans | Mid-ocean ridge |
| The sea floor spreads apart along both sides of the mid-ocean ridge; molten material comes up through a crack and forms new crust. As a result, the ocean floor moves like a conveyor belt. What is this describing? | Sea-floor spreading |
| What evidence supports sea-floor spreading? | Molten material, Magnetic stripes, drilling samples |
| Lithosphere is broken into separate sections describes what? | Plates |
| How do plates move? | By convection currents in the mantle |
| What changes in the Earth do the plate movements create? | Volcanoes, mountain ranges, deep ocean trenches |
| Two plates move apart - mid ocean ridges or rift valleys | Divergent |
| Two plates come together - volcanoes or mountains | Convergent |
| Two plates slip past one another - earthquakes | Transform |
| What happens to the movement over time? | Changes the earth's surface. Caused Pangaea to break up |
