What is the slow process that is most responsible for the decrease in height of the Appalachian Mountains?
A. Plate tectonics converging
B. Plate tectonic subducting under another
C. Weathering and erosion from wind and water
C. Weathering and erosion from wind and water

Phase changes (solid to liquid, liquid to gas etc.) are considered a _______ change.
PHYSICAL CHANGE
200
Reproduction that leads to offsprings with GENETIC VARIETY and chance for NATURAL SELECTION when facing changes.
SEXUAL REPRODUCTION

Which has more kinetic energy if the car and bike moves at the same speed?
A. They have the same KE
B. Car has more KE because it has more mass
C. Bike has more KE because it has less mass
B! Car has more kinetic energy because it has more mass.
KE increases linearly to mass and exponentially to speed.

A student rolls a ball down the ramp shown in the picture below. The ramp is supported by four stacked books. The student removes two books from the stack. how does motion change?
A. The ball has a greater speed at the top of the ramp
B. The ball has a greater speed at the bottom of the ramp
C. The ball takes more time to roll off the ramp.
B. The ball will have a greater speed at the BOTTOM
The ball starts with more potential energy because of its greater height.
All the PE then converts to KE

How does heat transfer between a cup of cold water and the room?
A. Heat from the water goes into to the air
B. Heat from the air goes into the water
Heat from the air goes into the water
(Hot to cold)

At which point does the ball have the most KE?
The ball the most KE at point 1. PE from the start transforms to KE.
There is less PE into 2 so 3 will have less KE.

Give a reason for why sexually reproducing organisms are more likely to survive in a changing environment. Describe in 1-2 sentences.
Sexually reproducing organisms are born with genetic variety so some individuals may have adaptations to survive and reproduce

The class is trying to figure out if this block will sink or float. The density of water is 1g/cm^3.
Describe what students should do to calculate the block's density.
1. Measure the volume
2. Weigh the mass
3. Density = Mass divided by volume.
