This is the pattern formed in a fluid when heating causes part of the fluid to rise and then cooling causes it to sink again. Within Earth's mantle they circulate heat and drive plate tectonic processes. Within the atmosphere and oceans, they drive winds and weather patterns:Convection Cell
The answer is C, it makes the block easier to lift by changing the direction of the force needed to lift it
All above
Severe Droughts can make land unlivable, as all living things need food and water to survive
Answer:The surface heated air expands as it warms, becomes less dense than surrounding cooler air and rises as buoyant and turbulent bubbles. This is convection and is the main process by which the troposphere mixes and heats. Although convection stirs and mixes the troposphere, the higher it is the colder it becomes.
