Question 1: How are Conduction, Convection, and Radiation all similar?

Answer:

• - Energy transfer (all three processes involve the transfer of energy)

2- Heat transfer (Conduction, convection, and radiation are all methods of heat transfer)

Question 2: How does surface area affect the rate of thermal energy transfer?

Answer:

A larger surface area in contact between objects allows for more thermal energy to be transferred.

Question 3: How are Conduction, Convection, and Radiation all different?

Answer:

They differ in how heat is transferred: conduction requires physical touch, convection needs a moving fluid (like air or water), and radiation can travel through empty space without needing a medium to travel through

Question 4: What is the Coriolis effect?

Answer:

The Coriolis Effect makes things (like planes or currents of air) traveling long distances around Earth appear to move at a curve as opposed to a straight line.

Question 5: What causes heat to transfer?

Answer:

Temperature differences between 2 objects

Question 6: What are horse latitudes? Why was it given that name?

Answer:

The horse latitudes are two subtropical regions of high pressure that occur around 30° north and south of the equator.

The "horse latitudes" are named so because sailors on ships traveling to the New World would often get stuck in calm windless areas at these latitudes for extended periods, forcing them to sometimes throw their horses overboard to conserve drinking water

Question 7: What makes wind move faster?

Answer:

Wind is the movement of air caused by differences in air pressure. The greater the pressure difference, the faster the wind moves.Question 8: In the Northern Hemisphere, air curves to the _____ and in the Southern Hemisphere, air curves to the _______.

Answer:

In the Northern Hemisphere, air curves to the right and in the Southern Hemisphere, air curves to the left.Question 9: Describe jet streams. (How high above earth are the jet streams located? how big are they? How fast are they?)

Answer:

Jet streams are narrow bands of strong winds that circle the globe. Located about 10 km above Earth's surface They are hundreds of km wide but only a few km deep.Question 10: In which direction would the wind blow if an area has higher temperature, lower density, lower pressure?

Answer:

Wind will blow towards an area with a higher temperature, lower density, and lower pressure because wind naturally moves from high pressure to low pressure areas.

Question 11: What are the global winds? What are the 3 types of global winds?

Answer:

Global winds are the main wind belts that move across the Earth in a steady direction.(1) Polar Easterlies (2) Westerlies (3) Trade Winds Question 12: At what area on earth is warm, less dense air that forms low pressure found? Why is there low pressure and low density here?

Answer:

at the equator Warm air at the equator rises. As it rises, it becomes less dense, leading to lower pressure at the surface.

Question 13: The greater the differences in air pressure, the ___ air moves.

Answer:

faster

Question 14: What are the doldrums?

Answer:

The doldrums are a belt around the Earth near the equator where winds are calm or nonexistent.

Question 15: Describe the "uneven heating of land forms" phenomenon.

Answer:

"Uneven heating of landforms" refers to the phenomenon where different parts of the Earth's surface, like land masses and bodies of water, absorb and radiate heat from the sun at different rates, causing variations in temperature across the globe, which in turn drives weather patterns like wind and ocean currents; essentially, land heats up faster than water due to its different heat capacity, leading to these variations in temperature.

Question 16: What is radiation? Give an example.

Answer:

Radiation is when energy moves from one place to another in waves or particles

Example: When you feel warmth from the sun or getting an x-ray

Question 17: What is temperature?

Answer:

the measure of the average kinetic energy of the particles of a substance.

Question 18: How does air move in a convection current?

Answer:

Air moves upwards when it is warm and less dense, then cools and sinks as it becomes denser, creating a cyclical pattern of rising and sinking air that transfers heat from a warmer area to a cooler one

Question 19: How does distance affect the rate of thermal energy transfer?

Answer:

The farther apart two objects are, the slower the rate of heat transfer.

Question 20: What is conduction? Give an example.

Answer:

Conduction is when heat (energy) moves from one thing to another when they are touching each other Example: when you touch a hot stove and your hand gets warm because the heat from the stove moves into your hand

Question 21: What are trade winds? Which way do the trade winds curve?

Answer:

Trade winds are consistent winds that blow almost constantly toward the equator from the northeast in the Northern Hemisphere and from the southeast in the Southern The trade winds curve west, due to the Coriolis Effect.Hemisphere

Question 22: What is wind and what causes it?

Answer:

The movement of air caused by differences in air pressure is wind.The differences in air pressure that cause winds, are primarily driven by the sun's uneven heating of the Earth's surface Question 23: How do the polar easterlies affect the weather in the United States?

Answer:

They bring cold air masses and contributing to chilly weather, particularly during winter months, by pushing cold air from the Arctic towards lower latitudes.

Question 24: What would happen to the winds if the Earth was not rotating?

Answer:

If the Earth did not rotate, then there would be no deflection or curving of the global winds. Instead, the wind from the poles and the equator would travel in a straight path or back-and-forth pattern.
