Energy Distribution
| Question | Answer |
|---|---|
| Heat Energy from the sun is distributed on Earth by _______, ________, and __________. | Convection, conduction, and radiation. |
| _____ is the transfer of energy by electromagnetic waves that can travel through empty space. | Radiation |
| Earth’s surface warms due to direct sunlight which causes the air to rise. The air cools and sinks back down creating circular motion. The circulation of air is transferring heat and is known as.... | Convection |
| When air or water is heated, the molecules move ... (faster or slower) | Faster |
| Cooler air or water molecules move (faster or slower). | Slower |
| Cooler air or water has less energy. Therefore it is more ________ | dense |
| Warming your feet by the fire is what type of heat transfer? | Radiation |
| Warming your hands by holding a warm cup of hot chocolate is what type of heat transfer? | Conduction |
| When water heats and the hot water rises to the top creating a circular motion with the hottest always rising to the top, this heat transfer is known as _________________. | Convection |
| Molecules/atoms of water and air can be easily moved. When heated the molecules move farther apart. This means the substance is (less or more) dense? | less dense |
| Cooler water goes to the bottom of warmer water. (True or false) Why? | Cooler water is more dense that warmer water. Therefore, it is true. |
