Answer:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Answer:
Rate of change of volume of the pile 
Explanation:
Given -
Rate of increase of the base of the pile 
inches per minute
Height of the pile 
the radius of the base
Let "h" be the height of the pile and "r" be the radius of the base.
Then 
Radius "r" 
inches
Rate of change of radius i.e
Volume of conical pile
Change in volume of conical pile
Substituting the value of rate of change of radius, we get -
Rate of change of volume of the pile
Meiosis is the splitting of haploid gamete cells (Sperm and Egg)
