1. LAW OF SUPERPOSITION: When observing rock layers, the oldest rocks/fossils can be found at the ______________, while the youngest can be found at the _______________.
a. middle, bottom
b. left, right
c. bottom, top
d. top, bottom

2. Two rock layers contain fossils of similar organisms. What is likely true of these rock layers?
a. They were from different environments.
b. They had advantageous traits.
c. They had analogous structures.
d. They were from the same time period.
ps this is science

Answers

Answer:

Q1. Young rocks are found on top, and old layer are found on the bottom.

Q2. Layers of sedimentary rock. Fossil layers are fossils that formed in sedimentary rock. When, over a long time, layers and layers of sediments get deposited on top of each other, the weight of the top layers presses down on the bottom layers, forming them into rock called sedimentary rock

Explanation:

Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.

Steno proposed that if a rock contained the fossils of marine animals, the rock formed from sediments that were deposited on the seafloor. ... (c) Superposition: Sedimentary rocks are deposited one on top of another. The youngest layers are found at the top of the sequence, and the oldest layers are found at the bottom

Two seventh grade students are studying how sound waves are transferring energy. They hold a large pot near the side of a cut of water and bang the pot with a wooden spoon. The sound waves make waves in the glass of water. How would the students increase the amplitude of the waves in the glass of water?
Question 2 options:

Hit the pot faster at a higher frequency

Hit the pot softer with less energy

Hit the pot faster at a higher frequency

Hit the pot harder with more energy

Answers

Answer:

The Answer You Are Looking For Is D) Hit the pot harder with more energy.

Explanation:

The amplitude of a the sound waves can be increased with frequency and hitting the pot harder with more energy will increase the amplitude of sound waves in the glass of water.

What are sound waves?

Sound waves are mechanical  waves transferring energy through a medium. They are longitudinal mechanical waves, where, the direction of oscillation of particles is in the direction of waves.

The frequency of a wave is the number of wave cycles obtained per unit time. Frequency is directly proportional to the amplitude and energy of the wave but inversely proportional to wavelength and density of the medium through which it travels.

Glass is a denser material and thus frequency of waves through it will be less. Hence by increasing the energy of hitting the frequency and thus the amplitude of sound waves in glass can be increased. Thus option d is correct.
