Below is a diagram of the sun. bettina wants to place a circular arrow in one layer of the diagram to illustrate how energy is transferred in that layer. in which layer should bettina draw the arrow? w x y z

The answer is; W

This layer of the earth is the mantle. It is fluid because the rocks in the region have plasticity. The rocks in the region are heated from below by the core. The hotter bottom layers of the mantle begin to rise while the cooler upper layers sink to the bottom. These convection currents are responsible for the tectonic plate movement of the earth’s crust.  

have a great day because if you dont you and i will be sad

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
