earth systems
| Question | Answer |
|---|---|
| Inputs into Earth's systems include _____, information, and matter | energy |
| sensory cues or genes are examples of _____ inputs | information |
| geothermal activity or fossil fuel use are examples of _____ inputs | energy |
| carbon dioxide used in photosynthesis or wind dispersing seeds are examples of ____ inputs | matter |
| the process of cause and effect in a system is known as ______ | feedback loop |
| this type of feedback loop promotes stability within a system because the causes and effects cancel each other out | negative |
| this type of feedback loop are rare in natural environmental systems but common in systems changed by humans because the system becomes unstable | positive |
| the removal of soil | erosion |
| all the rock below or at the Earth's surface | geosphere |
| the hard rock just below or at the Earth's surface | lithosphere |
| the living part of the Earth | biosphere |
| the layer of gases surrounding Earth | atmosphere |
| all the water in any of the spheres of Earth | hydrosphere |
| T/F the Earth's spheres are separate and independent of one another | false |
| Three basic layers of the geosphere are the ____, mantle, and core | crust |
| this layer of the geosphere is a thin layer of cool rock | crust |
| this layer of the geosphere is a large layer of hot solid rock | mantle |
| this layer of the geosphere contains both a solid metal core and a layer of molten metals | core |
| 15 large sections of the lithosphere | tectonic plates |
| the heating and cooling of which layer of the geosphere cause tectonic plate movement? | core |
| T/F the tectonic plates move about 2 - 15 inches per year | false |
| T/F the movement of the tectonic plates affects climate and evolution | true |
| T/F the most recent supercontinent is known as Pangaea | true |
| a mountain, island, or continent formed by the movement of the tectonic plates: | landform |
| T/F from space, the atmosphere appears as a thin white line | false |
| in the atmosphere, this molecule acts as Earth's sunscreen protecting it from the sun's radiation | ozone |
| T/F greenhouse gases are harmful | false |
| gases such as carbon dioxide and methane which help to keep the Earth warm as compared to the freezing temperatures of outer space: | greenhouse gases |
| T/F most of the Earth's water is salt water | true |
| about ____% of the Earth's water is fresh water | 2.5 |
| T/F most of the Earth's fresh water is unusable in a frozen form | true |
| about ____ % of the Earth's water is fresh water in a usable form | 0.5 |
| most of the earth's usable fresh water is located ______ | underground |
| a network of complex interlinked systems which exchange energy, matter, or information | Earth's systems |
| a ___ is a network of parts, elements, or components that interact with and influence one another | system |
| systems receive and process ___ of energy, matter, or information, and produce ___ of energy, matter, or information | inputs; outputs |
| systems do not have well defined ___ which makes it difficult to decide where one system ends and another begins | boundaries |
| systems may exchange energy, ___ , and/or information with other systems | matter |
| inputs into Earth's systems can include both ___ energy and geothermal energy. | solar (other answers possible) |
| an event that is both a cause and an effect is a cyclical process known as ___ and can be either positive or negative | feedback loop |
| a predator-prey relationship in which the two populations rise and fall in response to each other is an example of a ___ feedback loop | negative |
| ___ feedback loops enhance stability by CANCELLING an action once it reaches an extreme | negative |
| erosion is an example of a ___ feedback loop | positive |
| positive feedback loops are relatively ___ in nature but ___ in environmental systems that people have changed | rare; common |
| scientists divide Earth into spheres, which are often described by their ___ rather than by their location | makeup |
| Earth's geosphere is made up of all the ___ at and below the surface of Earth | rock |
| the sphere of the Earth that consists of all the planet's living or once living things and the nonliving parts of the environment with which they interact is the ___ | biosphere |
| the outermost layer of Earth and the geosphere is known as the ___ | lithosphere |
| the hydrosphere includes all water on Earth, including all forms of liquid, solid, and ____ | vapor (or gas) |
| earth's spheres both overlap and ___ | interact |
| an earthworm tunneling through the soil is an example of the biosphere interacting with the ___ | lithosphere |
| eroded soil deposited elsewhere | deposition |
| water changes from liquid to gas | evaporation |
| water vapor escapes from plants | transpiration |
| condensation returns to surface from atmosphere | precipitation |
| water changes from gas to liquid | condensation |
| rock and soil that stores water | aquifer |
| fresh water underground | groundwater |
