Which of the following best describes the relationship between the Sun and Earth's climate zones?
A
The Sun's energy is distributed unevenly across Earth's surface, creating different climate zones such as tropical, temperate, and polar regions.
B
Climate zones are determined solely by ocean currents, not by the Sun's energy.
C
The Sun only affects the climate at the equator, while other zones are influenced by the Moon.
D
The Sun heats all parts of the Earth equally, resulting in a uniform global climate.
Verified step by step guidance1
Understand the role of the Sun in Earth's climate system: The Sun is the primary source of energy for Earth's climate. Its energy drives atmospheric and oceanic circulation, influencing temperature and weather patterns globally.
Recognize the uneven distribution of solar energy: Due to Earth's spherical shape and axial tilt, the Sun's energy is distributed unevenly across the planet. Areas near the equator receive more direct sunlight, while regions closer to the poles receive less energy.
Identify the resulting climate zones: The uneven distribution of solar energy creates distinct climate zones. Tropical regions near the equator are warm, temperate zones are moderate, and polar regions are cold due to the varying intensity of sunlight.
Clarify misconceptions: Climate zones are not determined solely by ocean currents; they are primarily influenced by the Sun's energy. Additionally, the Sun affects all parts of Earth, not just the equator, and the Moon does not play a significant role in determining Earth's climate zones.
Conclude the relationship: The Sun's uneven energy distribution across Earth's surface is the key factor in creating different climate zones, such as tropical, temperate, and polar regions.
