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

Which statement is true? Hmm... is there more than one correct statement? Be sure to choose ALL correct statements.

• Heat rises when atoms and molecules cool down and begin to move faster and spread out. Colder substances are less dense and sink.

• Heat rises when atoms and molecules are heated and begin to move faster and spread out. Colder substances are more dense and sink.

• Heat rises when atoms and molecules freeze and begin to melt causing them to rise. Hot substances have faster moving molecules and these sink quickly.

• Heat rises when convection currents from the outer core cause heat to rise within the mantle. When these rocks are heated and then cool down they sink again = Convection currents in the mantle.
