Sdhc 6Th Grade Semester 1 Review

Front 1

Replication

Back 1

When someone else repeats an experiment to see if they get the same results. Same results will confirm the experiment as true.

Front 2

Observation

Back 2

Any information gathered using the five senses.

Front 3

Inference

Back 3

A conclusion that is made based on an observation.

Front 4

Model

Back 4

A visual or mathematical representation of an object or system. Good to use when the object is to small or to large to be directly observed.

Front 5

Physical weathering

Back 5

The breakdown of rock by physical forces.

Caused by:

Freezing-Ice wedging

Wind

Rain

Gravity

Animal action

Front 6

Chemical Weathering

Back 6

The breakdown of rock by chemical reagents.

Caused by:

Combining with oxygen(rust)

Reactions with Acids in water or from living things.

Front 7

Weathering

Back 7

Break down of rock by physical or chemical forces.

Front 8

Erosion

Back 8

The process where broken down rock is moved from one place to another.

Front 9

Deposition

Back 9

When sediment that is being moved is dropped off and comes to rest.

Front 10

Sand Dune

Back 10

A mound of sand deposited by the wind. Will move in the direction the wind is blowing.

Front 11

Alpine glaciers

Back 11

Will slowly flow down a mountain and cause a U shaped valley.

Front 12

Glacier

Back 12

A large mass of slowly moving ice.

Front 13

Temperature

Back 13

The average kinetic energy of particles

Front 14

Thermal energy

Back 14

The total kinetic energy of the particles

Front 15

Heat

Back 15

Energy transferred between objects of different temperatures. Always transfers from higher energy to lower energy.

Front 16

Thermal Expansion

Back 16

An increase in volume (size) due to an increase in temperature.

Front 17

Radiation

Back 17

Transfer of heat energy by electromagnetic waves. No contact.

Front 18

Conduction

Back 18

Transfer of heat energy by direct contact

Front 19

Convection

Back 19

Transfer of energy due to the movement of matter. Heated matter will rise and cool matter will sink. Causes currents.

Front 20

Water Cycle

Back 20

The movement of water between the atmosphere, land, oceans, and even living things.

Front 21

Evaporation

Back 21

When liquid water changes into water vapor (gas).

Front 22

Transpiration

Back 22

The release of water vapor into the air by plants

Front 23

Sublimation

Back 23

When solid water changes directly into a gas.

Front 24

Condensation

Back 24

The change of state from a gas to a liquid. It is how clouds form.

Front 25

Precipitation

Back 25

Any form of water that falls to the Earth from clouds. Rain/Hail/Snow.

Front 26

Energy Changes
Evaporation

Back 26

Water gains energy as it goes from a liquid to a gas. Usually due to an increase in temperature.

Front 27

Energy Changes
Sublimation

Back 27

Water gains energy as it goes from a solid to a gas. Usually due to low pressure and cold winds.

Front 28

Energy Changes
Condensation

Back 28

Water loses energy as it changes from a gas to a liquid. Usually due to a decrease in temperature.

Front 29

Weather

Back 29

The condition of the Earth's atmosphere at a certain time and place.

Front 30

Climate

Back 30

Average weather conditions in an area over a long period of time.

Front 31

Humidity

Back 31

The amount of water vapor in the air.

Front 32

Dew Point

Back 32

The temperature at which more condensation than evaporation occurs. Water droplets will form on the surface of things or fog will be in the air.

Front 33

Air Pressure

Back 33

The force of air molecules pushing on an area.

Front 34

Wind

Back 34

Air that moves horizontally, or parallel to the ground.

Front 35

Visibility

Back 35

a measure of the transparency of the atmosphere. It will be how far you can see into the distance.

Front 36

Air Mass

Back 36

A large volume of air in which temperature and moisture content are nearly the same throughout.

Front 37

Front

Back 37

A boundary between two different air masses.

Front 38

Jet Stream

Back 38

Long distance winds that travel above global winds for thousands of kilometers.

Front 39

Geosphere

Back 39

the mostly solid rocky part of the earth

Front 40

hydrosphere

Back 40

the part of the Earth that is liquid water.

Front 41

cryosphere

Back 41

made up of all of the frozen water on the Earth

Front 42

Atmosphere

Back 42

A mixture of mostly invisible gasses that surrounds the Earth.

Front 44

Air pressure and Altitude

Back 44

Air pressure will decrease as altitude increases
