Sixth Grade Science Vocabulary

The measure of the force with which air molecules push on a surface. Air pressure
A mixture of gases that surrounds a planet, moon, or other celestial body. Atmosphere
The transfer of energy as heat through a material. Conduction
The movement of matter due to the differences in density that are caused by temperature variations; can result in the transfer of energy as heat. Convection
Any movement of matter that results from differences in density, may be vertical, circular, or cyclical. Convection Current
The curving of the path of a moving object from an otherwise straight path due to Earth's rotation. Coriolis Effect
One of Earth's spheres where water is in solid form, including snow cover, floating ice, glaciers, ice caps, ice sheets, and frozen ground permafrost. Cryosphere
Information gathered by observation or experimentation that can be used in calculating or reasoning. Data
A stream like movement of ocean water far below the surface. Deep current
All of the nonliving things, living things, and processes that make up the planet Earth, including the solid Earth, the hydrosphere, the atmosphere, and the biosphere. Earth system
The observations, measurements, and other types of data that people gather and test to support and evaluate scientific explanations. Empirical evidence
an organized procedure to study something under controlled conditions. Experiment
The mostly solid, rocky part of the earth, extends from the center of the core to the surface of the crust. Geosphere
The movement of air over Earth's surface in patterns that are worldwide. Global wind
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. Greenhouse effect
The energy transferred between objects that are at different temperatures. Heat
The portion of Earth that is water Hydrosphere
A testable idea or explanation that leads to scientific investigation Hypothesis
A narrow band of strong winds that blow in the upper atmosphere. Jet stream
A descriptive statement or equation that reliably predicts events under certain conditions. Law
The movement of air over short distances; occurs in specific areas as a result of certain geographical features. Local wind
The layer of the atmosphere between the stratosphere and the thermosphere and in which temperature decreases as altitude increases. Mesosphere
A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept. Model
the process of obtaining information by using the senses; the information obtained by using the senses. Observation
A movement of ocean water that follows a regular pattern. Ocean current
The layer of the atmosphere at an altitude of 15 to 40 km in which ozone absorbs ultraviolet solar radiation. Ozone Layer
The transfer of energy as electromagnetic waves. Radiation
The knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested. Science
28. The layer of the atmosphere that lies between the troposphere and the mesosphere and in which temperature increases as altitude increases; contains the ozone layer. Stratosphere
A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface. Surface current
A measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object. Temperature
The explanation for some phenomenon that is based on observation, experimentation, and reasoning; that is supported by a large quantity of evidence; and that does not conflict with any existing experimental results or observations. Theory
The total kinetic energy of a substance's atoms. Thermal energy
An increase in the size of a substance in response to an increase in the temperature of the substance. Thermal expansion
The uppermost layer of the atmosphere, in which temperature increases as altitude increases. Thermosphere
The lowest layer of the atmosphere, in which temperature drops at a constant rate as altitude increases; the part of the atmosphere where weather conditions exist. Troposphere
The movement of deep, cold, and nutrient rich water to the surface. Upwelling
Any factor that can change in an experiment, observation, or model Variable
The movement of air caused by differences in air pressure. Wind
All the living organisms on Earth in the air, on the land and on the waters; one of the four parts of the Earth system. Biopshere
