Answer: Its the first answer.
Explanation:
Michael is looking for examples of energy at the park. He notices a mother pushing her child on a swing. He graphs the number of back-and-forth swings that the child completes each minute. Which of these describes the pattern in the graph?
A.The mother decreased the force of her push on the swing.
B.The potential energy and speed of the swing decreased over time.
C.The energy of the child on the swing changed from kinetic to potential.
D.The kinetic energy of the child on the swing increased over time
Answer:
D.
Explanation:
As you see, the graph INCREASES, which means it goes up. It is not going down, only rising.

Metamorphic
Volcanic
Igneous
Sedimentary
Answer:
sedimentary i think
Explanation:
Answer:
Rock A sedimentary
Rock B Metamorphic
Explanation:
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
