It takes 10 seconds for the ball to go from the starting line to the finishing line, 20 m away. What is the speed of the ball?
2 meter/second (distance over time)
____________ is the tendency of an object to resist change in motion.
inertia
where do intrusive igneous rocks form?
- beneath the surface
type of waves
Transverse and compressional
Describe how shearing causes rocks to break apart or move
- sliding past one another
You push a crate with a force of 10 N to the right, and your friend pushes on the crate with a force of 25 N to the left. Describe the motion of the crate.
(25 N left - 10 N right) =15 N left
________________ was the original supercontinent.
Pangaea
What are two major differences between mechanical and electromagnetic waves?
1. Mechanical can be compressional and transverse, electromagnetic is only transverse 2. Mechanical waves have to have a medium, transverse do not
What are the three types of forces?
Tension Compression Shearing
Describe the plate boundary Divergent and its movement
-dividing (pulling apart) , sea floor spreading, rift valleys, and new land
What is ordinary/white light made of?
All the colors, the visible light spectrum
label amplitude
Frequency
Number of wavelengths pass a point in one second
The force of ______________ will cause a ball rolling down a ramp to speed up the further it rolls
gravity
Point in the crust where energy is released
focus
On which layer of the Earth are all living things found?
crust
What are the two parts of a compressional wave?
Amplitude
half the distance from crest to trough (amp goes up, so does loudness )
What type/shape of wave does sound travel in?
compressional
Describe how tension causes rocks to break apart or move
- pulling apart
When you graph the motion of an object, you put _____ on the horizontal (x) axis and ___________ on the vertical (y) axis
time distance
Describe how compression causes rocks to break apart or move
- pushing together
What are the types of plate boundaries?
Convergent Divergent Transform
What are the two parts of transverse wave?
differences among species of similar populations
variations
Speed
Distance/ time
Speed is calculated by __________ divided by ____________
distance time
How are waves organized in the electromagnetic spectrum?
by wavelength
Landforms can be created or changed by which two natural events that happen because of plate movement?
Earthquake, volcanic eruption
How do Igneous rocks form?
- when magma/lava cools
What do waves transmit?
energy
Describe the plate boundary Transform and its movement
-sliding beside each other (like strangers) , earthquakes
________ forces are equal in size but________ in direction
balanced opposite
What makes an object appear to be different colors?
The color it reflects is the color you see, it absorbs all other colors
Which of the following situations will make two balls of different mass (one heavy, one light) roll down the ramp in the same amount of time? a. The balls will finish in the same time regardless of the mass. b. The length of the ramp is increased for the larger ball. c. The initial force is increased to push the larger ball onto the ramp. d. The friction on the ramp is increased for the larger ball.
b and d
It is more difficult to change the direction of a ___________ moving object
faster
____________ and ______________ determine the amount of friction acting on an object
force surface type
What type of medium can sound travel through?
Solid liquid gas
An object at rest has ___________________ forces acting on it
balanced or two
What was the original theory to describe the movement of land over time?
Theory of Continental Drift
Trait or behavior that helps survival
adaptation
What are the three types of rocks?
Igneous Metamorphic Sedimentary
Wavelength
distance from crest to crest/ trough to trough (shorter wavelength means higher frequency and more energy)
If an object is in motion and more _________ is applied to it, it will begin moving faster
force
Describe the plate boundary Convergent and its movement
-coming together, make mountains, volcanoes, subduction zones etc.
Point on the surface of Earth that is directly above where energy is released
epicenter
where do extrusive igneous rocks form?
- above the surface
Which type of wave has the shortest wavelength and most energy?
(infrared, visible, or ultraviolet) ultraviolet
If the line is horizontal on a graph the object has __________
stopped
label wavelength
