1. Heating of the Land and Water:
- Land: Daytime (warmer), Nighttime (colder), Which cools off quicker (Land), Which heats up faster? (Land)
- Ocean: Daytime (colder), Nighttime (warmer), Which cools off quicker (Land), Which heats up faster? (Land)
2. Land Breezes vs. Water Breezes AND Ocean Currents:
a. What is heating the surface of the Earth? Sun
b. Label in the diagram above the following:
i. Warmer during the day: land
ii. Warmer during the night: ocean/sea
iii. High density and low density: high density = cooler air over ocean at night / cooler air over land during day; low density = warmer air over land during day / warmer air over ocean at night
iv. Ocean current direction: during day, currents move away from land; during night, currents move toward land
v. Air particles/molecules: during day, warm air rises over land, cool air sinks over ocean; during night, warm air rises over ocean, cool air sinks over land
c. The sun heats the surface unevenly.
i. This causes convection currents in the atmosphere.
ii. This causes convection currents in the sea/ocean.
d. Open/Closed System:
i. The system is showing heat transfer and air/water movement due to solar energy.
ii. Matter flowing: air and water.
iii. Energy in the system: solar radiation.
iv. Open system for matter — because air and water exchange with surrounding environment.
v. Open system for energy — because energy enters from the sun and radiates back to space.
