Seawater near the equator is quite warm, while seawater near the poles is considerably colder. Water currents that flow from the equator to the poles move heat from warmer climates to colder ones. These currents move heat by the process of (1) _______________.  When a volcano erupts, hot molten rock can come to Earth’s surface. This lava burns or melts most things it touches. The lava is so hot it can set a tree on fire even if the tree is several feet away from it. This phenomenon is caused by the process of radiation. On a sunny beach, the sand becomes hot enough to be uncomfortable to your bare feet. However, if a wave washes over the hot sand, the cooler water removes heat from the sand by the process of conduction.

We are constantly surrounded by many types of energy transfers and transformations, showing that energy in a system is conserved. Which of these statements are true about how energy is conserved through transfers and transformations? Choose the two that apply.

• Energy is conserved when a lamp is turned on because some of the electrical energy is transferred into thermal energy.

• Energy is conserved when thermal energy is transferred from your body to a coat.

• Energy is conserved when some of the chemical energy from burning a candle is transformed into thermal energy, while the rest of the chemical energy is transformed into light energy.

• Energy is conserved when electrical energy from a hair dryer is transferred into thermal energy and then transformed by conduction.
