Conduction is one way in which energy in the form of heat is transferred through the Earth system. Which of the following best describes how conduction causes magma to heat the surrounding rock inside Earth?

• The warm magma flows towards Earth’s surface and cools.

• Electromagnetic waves from the sun warm the magma, which in turn warms the surrounding rock

• Differences in the density of the magma cause movement in the magma, which warms the surrounding rock

• Molecules of magma collide with molecules of rock and transfer energy as heat
