Poll

How does air get it's energy

• Claim 1: Energy is transferred from the sun to the air

• Energy is transferred from the sun to the surface and then to the air.

How Does Air Get Energy

• Earth's energy source is the sun

• Air cannot be heated directly

  • Energy from the sun must first hit a surface (land/water)

  • The surface can then release energy into the air

Energy Map

The further you go, the more it gets low!

• The equator gets the most energy from the sun because it receives direct sunlight year-round.

• As you move farther away from the equator, there is less and less energy​

Multiple Choice

The place that receives the most energy from the sun is located at ___

• The North Pole

• The South Pole

• Europe

• The Equator

Global Air Temperature

• Look at this map, were are the warmest locations located?

Multiple Choice

Areas that receive a lot of energy will also have what type of temperatures?

• Hot

• Warm

• Cold

• Very Cold

Draw

Based on latitude, circle the location that is WARMEST.

Multiple Choice

Indonesia was the warmest because it is _ to/from the equator, and receives _ energy.

• Further/More

• Further/Less

• Closer/More

• Closer/Less

Multiple Choice

Palmas is closer to the equator than Neuquén. Which location has a warmer air temperature and why?

• Neuquén, because more energy is transferred from the sun directly to the air.

• Neuquén, because more energy is transferred from the sun directly to the surface, and then from the surface to the air.

• Palmas, because more energy is transferred from the sun directly to the surface, and then from the surface to the air.

• Palmas, because more energy is transferred from the sun directly to the air.

Energy Flow

• Goes high to low-- or hot to not/hot to cold

• Warmer temperatures always lose energy to colder temperatures

  • This means that cold always gains energy, while warm temps lose energy​

Poll

If the air is warmer than the ocean, which direction will energy flow?

• Energy flows from the air to the ocean.

• Energy flows from the ocean to the air.

• Energy flows back and forth at the same time.

• Energy doesn't flow at all.

Multiple Choice

If the ocean is warmer than the air, which one is GAINING energy?

• Ocean

• Air

• Both

• None

Multiple Choice

If the ocean is warmer than the air, which one is LOSING energy?

• Ocean

• Air

• Both

• None

Ocean Currents

Remember, ocean current temperatures depend on how much energy they are receiving from the sun!​

Subject | Subject

Draw

Draw

Circle the town that is GAINING energy from the water

Draw

Multiple Choice

Lüderitz and Florianopolis are the same distance from the equator and they are both near the ocean. Use the information on the map to answer these questions: How does the air temperature of Lüderitz compare to the air temperature of Florianopolis? Why? The air at Lüderitz is

• COLDER than Florianopolis. At Lüderitz, only a little energy is transferred from the ocean to the air. At Florianopolis, a lot of energy is transferred from the ocean to the air.

• COLDER than Florianopolis. At Lüderitz, energy is transferred from the air to the ocean. At Florianopolis, energy is transferred from the ocean to the air.

• THE SAME AS Florianopolis. They are both near moving ocean water, so the same amount of energy is transferred to the air at both locations.

• THE SAME AS Florianopolis. Even though the ocean water at each location is a different temperature, the same amount of energy is transferred to the air at both locations.

Multiple Choice

Dayton and Newport are the same distance from the equator and they are both near the ocean. Use the information on the map to answer these questions: How does the air temperature of Dayton compare to the air temperature of Newport? Why? The air at Dayton is

• WARMER than Newport. At Dayton, a lot of energy is transferred from the ocean to the air. At Newport, only a little energy is transferred from the ocean to the air.

• WARMER than Newport. At Dayton, energy is transferred from the ocean to the air. At Newport, energy is transferred from the air to the ocean.

• THE SAME as Newport. They are both near moving ocean water, so the same amount of energy is transferred to the air at both locations.

• THE SAME as Newport. Even though the ocean water at each location is a different temperature, the same amount of energy is transferred to the air at both locations.

Multiple Choice

Clare Island and Cartwright are the same distance from the equator and they are both near the ocean. Use the information on the map to answer these questions: How does the air temperature of Clare Island compare to the air temperature of Cartwright? Why? The air at Clare Island is

• WARMER than Cartwright. At Clare Island, energy is transferred from the ocean to the air. At Cartwright, energy is transferred from the air to the ocean.

• WARMER than Cartwright. At Clare Island, a lot of energy is transferred from the ocean to the air. At Cartwright, only a little energy is transferred from the ocean to the air.

• THE SAME as Cartwright. Even though the ocean water at each location is a different temperature, the same amount of energy is transferred to the air at both locations.

• THE SAME as Cartwright. They are both near moving ocean water, so the same amount of energy is transferred to the air at both locations.

Prevailing Winds

• Prevailing winds are winds that move in one direction and are strong enough to push ocean currents

  • This means that ocean currents and prevailing winds travel in the same direction

  • They can have similar amounts of energy (temperature)

Multiple Choice

Kuta and Rog are the same distance from the equator, and they are both near the ocean. Using the information in the map, how does the air temperature of Kuta compare to the air temperature of Rog? Why? The air temperature of Kuta is

• COLDER than Rog. The winds push ocean water that turns and follows the coasts. Only a little energy is transferred from the ocean to the air at Kuta, and a lot of energy is transferred from the ocean to the air at Rog.

• COLDER than Rog. The winds push ocean water that turns and follows the coasts. Energy is transferred from the air to the ocean at Kuta and energy is transferred from the ocean to the air at Rog.

• COLDER than Rog. Moving air with only a little energy turns and follows the coast toward Kuta; moving air with a lot of energy turns and follows the coast toward Rog.

• THE SAME as Rog. Both locations are the same distance from the equator. The winds push the ocean water, and it turns to follow the coast in both locations, so the same amount of energy is transferred to the air.

Multiple Choice

Arica and Beira are the same distance from the equator, and they are both near the ocean. Using the information in the map, how does the air temperature of Arica compare to the air temperature of Beira? Why? The air temperature at Arica is

• COLDER than Beira. The winds push ocean water that turns and follows the coasts. Energy is transferred from the air to the ocean at Arica and energy is transferred from the ocean to the air at Beira.

• COLDER than Beira. The winds push ocean water that turns and follows the coasts. Only a little energy is transferred from the ocean to the air at Arica, and a lot of energy is transferred from the ocean to the air at Beira.

• COLDER than Beira. Moving air with only a little energy turns and follows the coast toward Arica; moving air with a lot of energy turns and follows the coast toward Beira.

• THE SAME as Beira. Both locations are the same distance from the equator. The winds push the ocean water, and it turns to follow the coast in both locations, so the same amount of energy is transferred to the air.
