Which scenario best illustrates how water serves as an agent of energy transfer? Mark only one oval.
Water evaporating from the surface of a lake absorbs heat from the surrounding air, cooling the air temperature.

Which statement correctly explains the impact of heat exchange between the ocean and atmosphere has on shaping weather and climate patterns?
Heat exchange between the ocean and atmosphere primarily affects local weather patterns but has minimal impact on regional and global climate.
Heat exchange between the ocean and atmosphere influences regional weather patterns but does not significantly contribute to global climate variations.
Heat exchange between the ocean and atmosphere plays a crucial role in regulating both local weather phenomena, such as sea breezes and coastal fog, and larger-scale climate patterns, including El Niño and La Niña events.
Heat exchange between the ocean and atmosphere has little influence on weather and climate, as other factors such as greenhouse gas emissions have a more significant impact.
Which of the following phenomena is caused by heat exchange between the ocean and atmosphere?
Formation of hurricanes
Growth of forests due to photosynthesis
Melting of polar ice caps due to greenhouse gas emissions

Why does heat exchange between the ocean and atmosphere result in global weather phenomena?
The ocean absorbs heat from the atmosphere, leading to localized weather patterns but minimal impact on a global scale.
The ocean provides heat to various regions across the globe, influencing atmospheric circulation patterns and weather systems on a global scale.
Global weather phenomena primarily occur due to interactions between the atmosphere and landmasses, with minimal involvement of the ocean.
Ocean currents redistribute heat within the ocean but have negligible effects on atmospheric processes and weather patterns.
