Term | Definition |
Conduction | The process by which energy is transferred from a warmer object to a cooler object by physical contact. |
Convection | motion in a gas (as air) or a liquid in which the warmer portions rise and the colder portions sink. |
Heat | energy that is transferred from a warmer object to a cooler object. |
Precipitation | any type of liquid or solid water that falls to Earth surface, such as rain, snow or hail. |
Radiation | the emission of energy as electromagnetic waves |
Temperature | the degree or intensity of heat present in a substance or object |
thermal energy | the energy an object has due to the motion of its particles. |
thermal expansion | the general increase in the volume of a material as its temperature is increased. |
Weather | the condition of Earth's atmosphere at a particular time and place. |
Wind | the horizontal movement of air caused by differences in air pressure. |
chemical weathering | The chemical breakdown and decomposition of rocks by natural processes in the environment. |
Coastline | A location where land and ocean surface meet. |
Delta | A mass of material deposited in a triangular or fan shape at the mouth of a river or stream. |
deposition | The process in which material is laid down. |
dune | A mound of wind |
erosion | The process by which wind, water, ice, or gravity transports soil and sediment from one location to another. |
glacier | A large mass of ice that exists year round and moves over land. |
ice wedging | water in the ground freezes and expands causing a crack in the ground. |
lake | A filled or partially filled basin of fresh or salt water surrounded by land. |
physical weathering | The mechanical breakdown of rocks into smaller pieces that is caused by natural processes and that does not change the chemical composition of the rock material. |
river | A large natural stream of water that flows across land surfaces within a Channel. |
air pressure | The measure of force with which air molecules push on a surface. |
atmosphere | Mixture of mostly invisible gases. |
biosphere | Made up of living things on Earth. |
cryosphere | Made up of all the frozen water on Earth. |
geosphere | Mostly solid, rocky part of Earth. |
greenhouse effect | The warming of the surface and lower atmosphere of Earth that occurs when water vapor, carbon dioxide, and other gases absorb and reradiate thermal energy. |
hydrosphere | Part of Earth that is liquid water. |
matter | Anything that has mass and takes up space. |
system | a group of related parts that make up a whole. |
Stratosphere | Temperature INCREASES as altitude increases. Many jet aircrafts fly in this layer. The ozone in the stratosphere protects us from ultraviolet radiation. |
Thermosphere | Temperature INCREASES as altitude increases. This is where the space shuttle orbits. The aurora borealis occurs in this layer. |
Mesosphere | Temperature DECREASES as altitude increases. Mesosphere protects Earth from meteors. This is the coldest layer. |
Troposphere | Temperature DECREASES as altitude increases. Most weather occurs here. |
Applied Force | A force typical push or pull, pushing a door open, pulling a rope. |
Friction | Happens when two objects rub against each other. Friction opposes motion |
Normal Force | For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. |
Air Resistance | The air resistance is a type of frictional force that acts upon objects as they travel through the air. |
Contact Force | A force that can cause or change motion of an object by touching it. |
Non | Contact Force |
Magnetic Force | A kind of non |
Electric Force | Non |
Gravitational Force | The force of attraction between any two objects in the universe. |
Energy | the ability to do work |
Law of Conservation of Energy | is NEVER created or destroyed, it can only be STORED or TRANSFERRED. |
Potential Energy | The energy stored in an object. |
Kinetic Energy | The energy of a moving object. |
experiment | An organized procedure to study something under controlled conditions is called: |
hypothesis | A testable idea or explanation that leads to scientific investigation based on prior knowledge is known as: |
theory | The statement based on repeated experimental observations that describe why the universe works under certain conditions |
scientific law | The statement based on repeated experimental observations that describe how the universe works under certain conditions. |
control group | The group in the experiment used as a baseline because nothing is different from its normal state |
dependent variable | The variable that is measured for change. The variable that is affected by the independent variable |
test (independent) variable | The variable that is changed. The variable that causes the change |
valid | When something is supported by evidence that is reliable and relevant |
