Q

Thermal energy equation

A

KE+PE

23
Q

Heat

A

Flow of energy through an object

24
Q

Specific heat

A

Amount of thermal energy needed to I increase a certain mass by 1c

25
Q

Thermal energy equation

A

Q=mC

26
Q

Calorie

A

Unit of thermal energy
Energy stored in food
1. Stored as chemical energy
2. Released from burning food as thermal
3. Energy gained makes molecules move faster and KE increases
4. TE released by food=TE gained by water

27
Q

Plus oval properties

A

Increases at depth increases

State of matter changes

28
Q

Inner core

A

Highest Reno and pressure ( solid)
Hugest density middle of earth
Metallic materials

29
Q

Outer core

A

Lower temp and pressure than core
Less dense floats on top of core (iron)
Natalie minerals

30
Q

Mantle

A

“Lower mantle” “stifler mantle”
Lower temp and pressure than outer core (more solid)
Floats on outer core

31
Q

Crust

A

Solid, outermost
-continental, oceanic
Lowest temp, pressure, density
Lithosphere +upper mantle= asthenosphere

32
Q

Law of universal gravitation

A

Gravity is a force that causes mass to attract together

33
Q

Force of gravity equation

A

Fg=1/d^2

34
Q

Law of universal gravitation equation

A

Fg=Gm1m2/d^2

35
Q

Plates

A

Sections of earth crust

36
Q

Convergent boundary

A

37
Q

Divergent boundary

A

Divide separate, oceanic, Continental

38
Q

Transform boundary

A

Slide past each other

39
Q

Lunar eclipse

A

Sun Earth Moon, full moon

40
Q

Solar eclipse

A

Sun moon earth, Newmoon

41
Q

Gravitation

A

If mass increases/decreases the force of gravity increases/ decreasesby the same amount

42
Q

Spring tide

A

Highest high lowest low, new or full moon

43
Q

Neap tides

A

First-quarter third-quarter moon, low highs and Highlow’s

44

Wave

A

Repeating disturbance the transfers energy through matter or space

45
Q

Transverse waves

A

Mme. is perpendicular to the direction of the wave travels

Crescent troughs

46
Q

Compression wave

A

Matter moves in the same direction as the wave travel

Compressions and refractions

47
Q

Wavelength

A

Distance between identical points

48
Q

Frequency

A

Number of wavelengths per second

49
Q

Period

A

Time for one wavelength to pass

50
Q

Amplitude

A

Amount of energy transfer
High-altitude equals higher across the tighter compressions
Low amplitude equals lower trough are lower refractions
