The three examples of convection are
The stack effect is also referred to as the chimney effect which is the movement of air inside and outside of buildings, flues or any other objects because of buoyancy principle. In oceanic circulation warm water around the equator circulates towards the poles and the cooler water at the poles moves towards the equator. In hot air balloon, a heater inside the balloon heats the air and so the air moves upward.
Answer:
The Atmosphere
The Ocean
Pot of Boiling Water
The Earths Crust
Explanation:
One place where convection occurs is in the atmosphere. Remember that air is a fluid that moves continuously. Air circulation on both a small-scale and a large-scale is driven by convection. Small-scale air circulation includes local winds, like sea breezes, and land breezes. Large-scale air circulation refers to the global circulation of the entire planet. Let's look more closely at sea breezes and land breezes. Both sea breezes and land breezes occur where there's a land mass directly next to a larger body of water, like a large lake or ocean. During the day land warms up faster than the water. So the air over the land is warmer than the air over the water. This warm air over the land rises because it's less dense. As it rises the air cools and eventually sinks towards the water because it's more dense. The cool air over the water then moves on shore to replace the rising warm air. This on shore wind is known as a sea breeze. At night land cools off faster than the water, so the air over the water is warmer than the air over the land. This warm air over the water rises because it is less dense. As it rises the air cools and eventually sinks towards the land because it's more dense. This cool air over the land then moves offshore to replace the rising warm air. This offshore wind is known as a land breeze. The convection seen with sea breezes and land breezes is the same as the convection seen in the pot of boiling water.
Another place where convection occurs is in the ocean. Ocean water is a fluid that moves continuously. This movement is partially driven by convection. It's the deep ocean circulation that's driven by convection along with salinity, which is a measure of the dissolved salt in ocean water. The surface ocean currents are mostly driven by wind. So the deep ocean circulation that's caused by convection is also called the global conveyor belt. So cold, salty ocean water in the Norwegian Sea, up here, drifts down and moves south all the way to Antarctica. So it sinks to the bottom because it's very dense and cold. And then it goes and travels down towards Antarctica. Now, eventually the conveyor belt turns and that cold water starts traveling northward up towards the equator. As it does so it warms and rises to the surface because it's less dense. It then flows near the surface back to the Norwegian sea, completing this whole cycle.
The convection seen with the deep ocean circulation is the same as the convection seen in the pot of boiling water. Remember that thermal energy is being transferred throughout the ocean because of this conveyor belt.
Have a nice day brainlys!
