A. The Moon
B. The Earth’s Surface
C. The Sun
D. The rotation of Earth

Please select the correct option that explains the initial source of winds.

Answer 1

The initial source of winds is the Sun, which causes uneven heating of the Earth's surface, leading to variations in pressure and subsequent movement of air to equalize these differences.

Step-by-step explanation:

The correct option that explains the initial source of winds is C. The Sun. Winds are caused by the uneven heating of the Earth's surface by the Sun. This uneven heating creates areas of high and low pressure, leading to air movement as the atmosphere tries to equalize these pressure differences. The rotation of Earth also influences wind patterns giving rise to phenomena like the Coriolis effect, but it is not the initial source. This creates an area of low pressure over the land.

Meanwhile, the cooler air above the ocean creates an area of higher pressure. The air then flows from the ocean to the land, creating a sea breeze. Sun energy heats up the surface causing thermal energy variations, this expanding and rising warm air creates low-pressure areas and the cooler air descends forming high-pressure areas, initiating airflow from high to low-pressure, creating winds.
