Answer:
It also plays a key role in vision. As light enters your eye, it gets refracted, or bent, by the cornea's curved edge. This helps determine how well your eye can focus on objects close-up and far away. If your cornea is damaged by disease, infection, or an injury, the resulting scars can affect your vision.
What is one characteristic that is similar between reflection and refraction? They both describe how light rays -
A: bend when moving from one material to another
B: travel fast as they strike a material
C: bounce off of a material
D: interact with different types of materials

Compare the sound of thunder to the sound of a fire alarm at school. How are the wavelengths, frequencies, and amplitudes similar or different?
Answer:
The fire alarm is a higher pitch than thunder.
Explanation:
The fire alarm is a higher pitch so the wavelengths are going to be closer and the amplitude is going to be taller, and the thunder is a lower pitch, so the wavelengths are going to be farther and the amplitude is going to be smaller.
The wavelengths, frequencies, and amplitudes are different for the sound of thunder as compared to the sound of a fire alarm.
Characteristics of sound:The sound of thunder is low pitched sound, whereas the sound of a fire alarm is a high-pitched sound.
The pitch of a sound depends on the frequency of the sound, a higher frequency has a higher pitch. Whereas loudness depends on the amplitude of the sound.
For a low-pitched sound, the slope of the wave on the amplitude and time plot is flatter which means that the wavelength of the sound is larger and the frequency is smaller.
For a high-pitched sound, the slope of the wave on the amplitude and time plot is sharper which means that the wavelength of the sound is smaller and the frequency is larger.

a. Faults and volcanoes existed long before there were tectonic plates.
b. Faults and volcanoes are often found at tectonic plate boundaries.
What 4 things affect how great the change in temperature for a substance is?
Explanation:
The heat Q transferred to cause a temperature change depends on the magnitude of the temperature change, the mass of the system, and the substance and phase involved.
Answer: Usually, increasing the temperature increases the solubility of solids and liquids. Increasing the temperature always decreases the solubility of gases.
Explanation:
When you add a solute to a solvent, the kinetic energy of the solvent molecules overcomes the attractive forces among solute particles.
The solute particles leave the surface of the solid and move into the dissolved (aqueous) phase. In the image below the mass of grey (-) balls and green (+) balls represent a salt crystal. As the salt dissolves, the positive and negative ions are pulled apart and become surrounded by water molecules.
If we heat the solvent, the average kinetic energies of its molecules increases. Hence, the solvent is able to dislodge more particles from the surface of the solute.
Thus, increasing the temperature increases the solubilities of substances. For example, sugar and salt are more soluble in water at higher temperatures.
But, as the temperature increases, the solubility of a gas in a liquid decreases. As temperature increases, the average kinetic energy of the gas molecules increases.
As a result, the gas molecules dissolved in the liquid are more likely to escape to the gas phase and not return.

write a brief paragraph that explains the correlation between, Earths energy budget, global warming, the greenhouse effect, atmospheric ozone, and carbon dioxide.
paragraph must be up to 3-5 sentences.
Answer: The correlation between all of these examples would be They are all earths natural energy balance. To maintain a constant global average temperature, all of the sun’s radiation that enters Earth’s atmosphere must eventually be sent back to space. The greenhouse effect plays a significant role in Earth's energy budget. With the natural greenhouse effect, the energy budget is balanced as thermal radiation is re-radiated towards the ground, trapping thermal energy and warming the Earth. However, with the greenhouse effect being enhanced by humans, the energy budget of the Earth is shifted to an imbalance. It is important to understand that a certain amount of energy being retained due to the greenhouse effect is necessary, but too much results in conditions that account for increased global temperatures and climate change.

Explain how the skin is a factor in the regulation of body temperature.
Answer: The prodigious blood flow of the skin avails control temperature: dilated vessels promote heat loss, while heat is preserved by constricted vessels. In its supply of oxygen, the skin controls body temperature. In homeostasis, the skin fortifies. By inhibiting sweat evaporation and ergo heat loss, sultriness controls thermoregulation.
