Buffalo, New York is a city located near a large lake called Lake Erie. Buffalo receives an average of nearly 94 inches of snowfall a year. Using your knowledge of temperature and what you have read, explain why Buffalo receives so much snow.
Answers
Answer: it is further away from the equator
Explanation:
The simple answer to why Buffalo receives so much snow, and why it is is often confined to a specific area, is lake effect snow. Lake effect snow occurs most frequently during cold snaps in early winter. It happens when the transfer of heat and moisture from the warm waters of the Great Lakes to the cold air creates a shallow layer of atmospheric instability, causing air to rise quickly. As the moisture rises and condenses, it begins to fall as snow–and often, a lot of snow. Depending on which direction the winds are blowing, areas in the snow belts near the Great Lakes (including Buffalo) can see several feet of snow in just a few days. According to the National Weather Service, in the Buffalo area, when cold air from Canada moves over the still unfrozen, relatively warm Great Lakes, the lake moisture and instability from this temperature contrast build one or more bands of snow. These bands are then deposited over locations downwind from the lakes, with some areas receiving much more snow than others, depending on their location and the wind direction.

• Acceleration: change in velocity compared with the time it takes to change
- Average Acceleration: (Final Velocity - Starting Velocity) / Time
• Velocity: expressed in meters per seconds (m/s)
• Time: expressed in seconds (s)
• Acceleration is measured in meters per second per second
- meters per second squared (m/s²)
Picture #2:
• Acceleration is a vector
- magnitude
- direction
• Acceleration: increases and decreases in speed
• Positive Acceleration: increase in speed
- sliding down from a hill
- small velocity -> large velocity
• Negative Acceleration: decrease in speed
- car slowing then
- high velocity -> low velocity
- initial velocity is larger than final velocity
- (v2 - v1) will be negative
- acceleration “a = (v2 - v1) / t” will be negative
• Acceleration and velocity (rate of motion) in the same direction = speed will increase.
• Acceleration and velocity in opposing directions = speed will decrease
Picture #3:
• Acceleration: rate at which velocity changes
• Velocity is a vector: has magnitude & direction
- magnitude or direction changes = the velocity changes
• Object accelerates speed = direction of motion or both magnitude and direction changes
• Acceleration depends on amount of time for the change to take place and how much velocity changes
- Small change in velocity can be a large change in acceleration if the change occurred quickly.
- Large change in velocity can be a small change in acceleration if the change occurred slowly.
- Increasing speed by 5 m/s in 5 seconds is smaller acceleration to increase speed by 5 m/s in 1 second.
Picture #4:
• An object changing the direction of motion experiences acceleration even when not speeding up or slowing down
• An object is always turning.
• Centripetal Acceleration: acceleration in circular mode.
when enough stress builds up in brittle rock, the rock breaks, causing a ___ to form
Answers
How do faults form? When enough stress builds up in rock then the rock breaks creating a fault. A normal fault occurs when rock is being pulled apart by tension; in this type of fault the hanging wall moves downward and the foot wall moves upward due to the tension in Earth's crust.

Which part of the ear converts vibrations into nerve impulses?
cochlea
auditory nerve
outer ear
eardrum
Answers
Answer:
cochlea
Explanation:
The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

Answers
Explanation:
Certain actions and/or their method can affect the environment, such as leaving the sink on while brushing your teeth or not turning off a light when you leave the room. I personally make decisions to prevent my association with Greenhouse gases by turning off lights when I leave a room, using minimal water, recycling, etc.
Answer:
Answers may vary. View explanation.
Explanation:
There are every day decisions that may add carbon dioxide to the environment.
Problems:
Burning of fossils fuels. Example: Using cars as transportation. The average car releases around 4.6 metric tons of carbon dioxide per year.Deforestation. Carbon dioxide is released from dead organisms such as trees. Example: As of 2021, 15 billion trees are lost to deforestation.Solutions:
Instead of taking your car to work or school, carpool with a friend. Riding your bike and taking the bus are also good solutions that help minimize carbon dioxide releases.In spare your time, grab a couple of friends and plant some trees! Even planting just a few trees is a great start to help the planet.Have a great day!

Which surface is most likely to create an echo?
a room with hard, flat walls
a room with hard, bumpy walls
a room covered in soft, wavy curtains
a room padded with soft, flat cushions
Answers
A room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.
What is echo?Echo is defined as a recurrence of sound caused by sound waves being reflected off of a wall, mountain, or other obstruction. Bats, dolphins, and fishermen all use echoes to find objects or obstructions. To find an obstruction, they are also utilized in SONAR (Sound navigation and ranging) and RADAR (Radio detection and ranging).
Buildings made of glass, metal, and concrete, the brick and metal interior of a warehouse, marble floors and buildings, or, if the room is designed in such a way that the acoustics produce an echo, plastered and painted interior walls, are examples of man-made materials that are smooth enough to produce an echo.
Thus, a room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.

part b:
Sodium bicarbonate is a white, crystalline powder that sometimes forms lumps. It is odorless and has a bitter, salty taste. At room temperature, it is a solid. Solubility, or the ability of a substance to dissolve in water, is also a physical property. Sodium bicarbonate is soluble in water and can be separated from water through evaporation.
Explanation:
In the reaction of baking soda with acetic acid carbon dioxide gas is evolved that's why the balloon inflates. The mass in the product side and reactant side ar equal and the the total mass is conserved.
What is mass conservation?According law of conservation of mass, mass can neither be created nor be destroyed. Therefore, the total mass of a system will be conserved. In a chemical reaction, the total mass of reactants is equal to the total mass of products and thus no mass loss occur there.
In the reaction of vinegar (acetic acid) and sodium bicarbonate or baking soda, the mass on both side is equal and we get the product mass equal to the total mass of reactants if the experiment is carefully done.
Sodium carbonate is a colourless weak base, which can easily react with an acid and gets protonated. When sodium bicarbonate that is NaHCO₃, with vinegar CH₃COOH, it will produce carbon dioxide and water.
This carbon dioxide gas evolves to the balloon which is stretched on the top and the balloon will inflates.The measurements will differ at each moment because we are measuring it in different events of the reaction where the gas is evolving out.
