The correct option is d, which states that differences in air density cause the rising and sinking of air This process is driven by the heating of the air at the equator, where warm, less dense air rises, cools down, and then sinks. As the temperature of air changes, the pressure of the air also changes This difference causes convection of air masses, resulting in high and low pressure systems and warm and cold fronts that move across the globe. The earth's spinning causes multiple convection cells to form above and below the equator These cells cause winds as air rises or sinks in different locations. Describe and explain the three basic cyclic reasons why the temperature of the earth has fluctuated over time (milankovitch cycles) Please make sure to use complete sentences and proper grammar. When energy from the sun reaches the air above land, the air warms and rises Along a coastline, cooler air above the ocean flows toward the land to replace this rising air. Air rises at the equator and sinks at the poles, creating a single convection cell in each hemisphere The prevailing winds moving over the earth’s surface blow from the poles towards the equator in both hemispheres (by paul webb via libretext Which best describes what is happening in the diagram At point 1, the air in the convection current is warmer and denser than at point 3 because its molecules contain more kinetic energy The warm air rises, while cooler air sinks towards the ground That cooler air is then warmed by the earth's surface and rises, continuing the convection pattern. The result is a loop of moving particles called a convection current For example, convection currents transfer thermal energy through molten rock below earth’s surface, through water in the oceans, and through air in the atmosphere. In the upper atmosphere, air moves poleward
