Fill in the blank: __________________ also happens inside the earth (see image). Tremendous heat and pressure within the mantle cause hot magma to flow in convection currents (rising and falling of liquid magma). This causes the plates in the crust (lithosphere) to shift and move and sometimes break.

• convection

• radiation

• conduction

• wind
