condensation

Answer 8

The process of gas changing into liquid, the act of making more dense

Question 9

conduction

Answer 9

The transfer of heat through a medium by direct contact

Question 10

conservation

Answer 10

Efforts to preserve natural resources

Question 11

Law of Conservation of Energy

Answer 11

The principle stating energy is not created nor destroyed (it only changes form)

Question 12

Law of Conservation of Mass

Answer 12

The principle that mass is not created nor destroyed.

It is used to balance chemical equations

Question 13

constellation

Answer 13

A group of stars forming shapes or figures in a certain area of the sky (ie. The Big Dipper)

Question 14

consumer

Answer 14

An organism that obtains its nutrients (feeds itself) from consuming other organisms

Question 15

convection

Answer 15

The transfer of heat by gas or liquid from the circulation of currents

Question 16

convergent boundary _{(1 of the Plate Tectonics words as well)}

Answer 16

An area where two tectonic plates collide

Question 17

covalent bond

Answer 17

A chemical bond in which an electron is shared by two atoms to fulfill their outermost energy levels

Question 18

crest

Answer 18

The highest point of a wave

Question 19

crust

Answer 19

The outermost layer of Earth (is over the mantle)

Question 20

decomposer

Answer 20

An organism that obtains nutrients by breaking down the organic matter of passed away organisms

Question 21

density

Answer 21

The concentration of matter within a certain volume or in an object

Question 22

dependent variable

Answer 22

The factor being measured in an experiment.

Is as result of the independent variable that you control

Question 23

deposition

Answer 23

The layering of matter, such as sediments, occurring naturally

These sediments are carried by wind, water etc and left where they may deposit upon eachother

Question 24

diffraction

Answer 24

The bending of a wave as result of an obstruction

Question 25

DNA

Answer 25

A nucleic acid carrying genetic material, code, existent in all cellular organisms

Question 26

dominance

Answer 26

The tendency of a dominant allele to mask the appearance of the related recessive gene

Question 27

**plate tectonics words** subduction

Answer 27

The process in which two tectonic plates collide on a convergent boundary, where the weaker plate slips **under **the stronger one, into the mantle.

_{This results in volcanic activity and earthquakes.}

_{This may occur with two continental plates, where as the weaker slides under, or an oceanic and continental plate (the oceanic plate slides under)}

Question 28

divergent boundary

Answer 28

An area where two tectonic plates diverge from each other

Question 29

rift valley

Answer 29

A valley landmark that occurs at a divergent boundary; when the two tectonic plates move away from each other they result in a depression in the landscape

Question 30

mid-ocean ridge

Answer 30

An underwater mountain range forming along a rift that occurs at a divergent boundary
