On the grid in your answer booklet, construct a line graph by plotting the average insolation refl ected during
the summer by the greenland ice sheet from 2006 to 2012. connect all seven plots with a line. [1]

Hi!
I don't have access to your grid, but iI can make my own to show you how to do it!

Please see attachment

on the y axis you can only use the relevant values - between 68 and 74; this way you can see more detail than if you'd used between 0 and 75.

You just need to plot the numbers and connect the line! (I did it with ms excel)

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
