Do the same forces that cause tides in the ocean also affect the solid Earth?
If so then what are some pieces of evidence that this is true

Answer:

no the moon does the tides. And i think tectonic plats and volcanos and a bunch of other stuff affect the earth

(8th Grade Science) Please help

Question 1 (2 points)
What state of matter is achieved if a large amount of energy is added to a gas? (2 points)

a
Vapor

b
Liquid

c
Plasma

d
Solid

Question 2 (2 points)
What happens to a gas when its temperature decreases? (2 points)

a
The gas becomes a plasma.

b
The molecules move more slowly.

c
The energy of the particles increases.

d
The atoms in the gas are destroyed.

Question 3 (2 points)
Mary and Ron are discussing what happens to the kinetic energy of molecules in a liquid as the liquid cools. Mary says it decreases. Ron says it stays the same. Who is correct and why? (2 points)

a
Mary is correct, because molecules are constantly losing kinetic energy no matter what state they are in.

b
Mary is correct, because as the liquid cools, the molecules slow down as they lose kinetic energy.

c
Ron is correct, because kinetic energy is a fixed characteristic of molecules and does not change.

d
Ron is correct, because kinetic energy can only increase, not decrease.

Question 4 (2 points)
Which quantity is directly related to the temperature of a substance? (2 points)

a
Average kinetic energy of the particles in the substance

b
Average size of the particles in the substance

c
Composition of the substance

d
pH of the substance

Question 5 (2 points)
As heat is added to a tube of gas, which is the most likely phase transition to occur in the tube? (2 points)

a
Gas to plasma

b
Gas to liquid

c
Gas to solid

d
Gas to element

Question 6 (2 points)
How do elements change as you move down a column in the periodic table? (2 points)

a
The atomic radius decreases.

b
The number of protons decreases.

c
The atomic mass decreases.

d
The electronegativity decreases.

Question 7 (2 points)
How are chemical and physical changes different on a molecular level? (2 points)

a
Chemical changes involve the breaking of bonds in molecules.

b
Chemical changes do not affect bonding between atoms.

c
Physical changes do not involve molecules.

d
Physical changes cause new molecules to form.

Question 8 (2 points)
How does the currently accepted model of the nucleus provide evidence of the existence of the strong nuclear force? (2 points)

a
The protons have like charges and should repel, so to stay near each other in the nucleus, there is a strong force holding them together.

b
The electrons have like charges and should repel each other, which is why they are scattered in the electron cloud.

c
The protons and neutrons have opposite charges and should attract each other, so to keep them apart, there must be a strong force in the nucleus.

d
The particles in the nucleus are separated by type, showing the existence of a strong force that keeps them apart.

Question 9 (2 points)
How do scientific models become stronger over time? (2 points)

a
New experiments verify or refine previous models.

b
As more people believe the model, it is stronger.

c
Older theories are always thought to be stronger than new theories.

d
Personal beliefs become more important to scientists over time.

Question 10 (2 points)
When scientists publish experimental results, their results are often criticized by other scientists. How is this process a source of strength of science? (2 points)

a
It encourages scientists to give convincing evidence for their results.

b
It allows scientists to keep their data secret.

c
A scientific model is not useful unless everyone thinks it is true.

d
It forces scientists to publish results that are in line with current theories.

Alika finds a certain kind of butterfly near her house. She reads that ultraviolet light is absorbed by the butterfly’s wings, red light is transmitted through the butterfly’s wings, and green light is reflected off the butterfly’s wings. Alika’s friend Claire tells her that if you shine a light on the butterfly, its wings will glow.

Can light cause the butterfly’s wings to glow? Why or why not? Does it matter what type of light Alika shines on the butterfly?

Which of the following statements are TRUE for the process of dissolving NaCl in water?
a. NaCl remains bonded together.
b. Na+ and Cl- become free ions.
c. The attractive forces between water and NaCl are weaker than the forces holding NaCl together,
d. All of the above
