The distance from one wave to another is called the...
wavelength
100
What is the Law of Superposition?
Newer rock layers form on top of older layers
100
What daily occurrence is caused by the rotation of the Earth?
Day and night cycle
100
What is the formula for speed?
Distance divided by time
s = d/t
100
What is the unit of measure for force?
Newtons (N)
200
What is the AMPLITUDE of a wave?
The height of a wave
200
Which layer of rock contains the YOUNGEST fossils?
Early horses
200
How long does it take for Earth to complete one rotation on its axis?
23 hours and 56 minutes (roughly 24 hours)
200
How is velocity different from speed?
Velocity contains the speed AND direction
200
What is the net force on this object?
5 N Up
300
Which tuba is louder, and why?
The bottom tuba is louder because the wave has a larger amplitude
300
What is relative dating?
Looking at rock layers to determine what is older
300
What causes the change in seasons?
Earth has a 23 degree tilt which causes a change in the amount of daylight
300
What is acceleration?
Acceleration is any change in velocity
300
Define potential energy and kinetic energy.
Potential energy: stored energy of an object due to its position
Kinetic energy: energy an object has due to its motion
400
The greater the FREQUENCY of a wave...
The higher the pitch of the wave
400
What is absolute dating?
Looking at atoms in rocks to determine their exact age
400
Which season is it in the NORTHERN hemisphere?
Winter (hemisphere is pointing away from the sun)
400
If a car travels at 30 miles/hour, how far would they get in 2 hours?
60 miles
400
Describe where potential energy would be the highest in this roller coaster.
At the top of the loop (where the cart would be at the coaster's maximum height)
500
The material that a wave travels through is called a...
Medium

A newly formed rock has 100% potassium which has a half life of 1.26 billion years. What percent of potassium would be left after 2.52 billion years in the rock?
25% Potassium

You drop a feather and pencil at the same on a mysterious planet and find that they land at the same exact time. What conclusion can you make?
The planet has no atmosphere (no air resistance to keep the feather afloat)
500
If a car moves 12 kilometers (km) north, 19 km east, and 12 km south, what is its displacement?
19 km
500
What is Newton's second law of motion?
The acceleration of an object depends on the mass of the object and amount of force applied
F=ma
