Question

how do atmospheric convection currents form between the equator and 30 degrees latitude? (1 point)
cold air descends near the equator
wind patterns create currents
warm air rises near the equator and sinks at 30 degrees latitude
pressure differences cause movement

Explanation:

To determine how atmospheric convection currents form between the equator and 30 degrees latitude, we analyze each option:

• "Cold air descends near the equator" is incorrect because the equator receives more direct sunlight, so air near the equator is warm, not cold, and warm air rises, not descends.
• "Wind patterns create currents" is a vague and incorrect description of the cause of convection currents in this region. Convection currents drive wind patterns, not the other way around in this context.
• "Warm air rises near the equator and sinks at 30 degrees latitude" is correct. At the equator, intense solar heating warms the air, causing it to rise (low - pressure area). This warm air moves towards the poles at high altitudes. As it moves towards 30 degrees latitude, it cools and becomes denser, then sinks (high - pressure area), creating the convection current.
• "Pressure differences cause movement" is too general. While pressure differences are involved, this option does not specifically describe the process of convection current formation between the equator and 30 degrees latitude as accurately as the third option.

Answer:

C. Warm air rises near the equator and sinks at 30 degrees latitude
