NB AP Write a well constructed paragraph explaining convection in the mantle! Use all the words from the bank!

NB Comp Copy and fill in the blanks using the word bank… The _____is the hottest part of the earth and gives _____ to the liquid ______. As the mantle warms up, it becomes _______ and rises toward the ______. At the crust it cools, loses _________, and becomes more dense sinking. This ______ of the mantle is called ________________________.

NB Comp Copy and fill in the blanks using the word bank… The CORE is the hottest part of the earth and gives HEAT to the liquid MANTLE. As the mantle warms up, it becomes LESS DENSE and rises toward the CRUST. At the crust it cools, loses ENERGY, and becomes more dense sinking. This MOVEMENT of the mantle is called CONVECTION CURRENTS.
