Energy Exit Ticket
| # | Answer |
|---|---|
| 1 | Energy is the ability to do work or cause change. |
| 2 | Examples include heat, light, sound, electrical, mechanical, or chemical energy. |
| 3 | The Sun. |
| 4 | Kinetic energy. |
| 5 | Chemical energy. |
| 6 | Thermal energy is the energy of moving particles in matter, related to temperature. |
| 7 | Wind. |
| 8 | Natural gas. |
| 9 | Light energy is changed into thermal energy. |
| 10 | The Sun provides energy that drives weather, climate, and temperatures on Earth. |
| 11 | Kinetic energy is energy of motion, and potential energy is stored energy. |
| 12 | Gravitational potential energy. |
| 13 | Kinetic energy. |
| 14 | From higher energy to lower energy. |
| 15 | It heats water so it evaporates into the atmosphere. |
| 16 | Evaporation. |
| 17 | It makes the particles move faster as thermal energy increases. |
| 18 | Geothermal energy is heat energy from inside Earth. |
| 19 | They can be replaced naturally and do not run out quickly. |
| 20 | They are nonrenewable and can cause pollution when burned. |
| 21 | The kinetic energy of moving air is changed into electrical energy. |
| 22 | The kinetic energy of moving water is changed into electrical energy. |
| 23 | They store chemical energy that can be changed into electrical energy. |
| 24 | Heat moving from a hot object to a cooler object is an example of energy transfer. |
| 25 | Sunlight hits the equator more directly, so more energy is received there. |
| 26 | Surfaces with high albedo reflect more sunlight and absorb less energy, helping keep them cooler. |
| 27 | Convection is the transfer of thermal energy by the movement of fluids like air or water. |
| 28 | Conduction is the transfer of thermal energy through direct contact. |
| 29 | Radiation is the transfer of energy by waves, such as sunlight, without direct contact. |
| 30 | Radiation. |
| 31 | Dark surfaces absorb more sunlight and convert more of it into thermal energy. |
| 32 | It absorbs, reflects, and traps some energy, helping keep Earth’s temperature stable. |
| 33 | The greenhouse effect is the warming of Earth when gases in the atmosphere trap some outgoing heat. |
| 34 | It helps keep Earth warm enough for liquid water and living things. |
| 35 | Fossil fuels are energy sources like coal, oil, and natural gas formed from ancient organisms. |
| 36 | Ancient plants captured sunlight through photosynthesis, and that energy was stored and later became fossil fuels. |
| 37 | Chemical energy is changed into thermal energy, and then into electrical energy. |
| 38 | Some energy is transferred as heat, so it is less available to do useful work. |
| 39 | They generate electricity without burning fuel or producing air pollution during use. |
| 40 | Earth’s tilt changes the angle and length of sunlight during the year, causing seasons. |
| 41 | Seasons happen because Earth is tilted as it orbits the Sun, changing how sunlight strikes each hemisphere. |
| 42 | A more direct angle concentrates energy on a smaller area, so the surface receives more energy. |
| 43 | Dark pavement absorbs more solar energy, while snow reflects more energy. |
| 44 | The Sun heats Earth unevenly, creating temperature and pressure differences that drive winds and storms. |
| 45 | Convection currents form, transferring thermal energy in the atmosphere. |
| 46 | Water heats and cools more slowly than land, so nearby areas change temperature less quickly. |
| 47 | Using efficient appliances, turning off lights, or reducing heating and cooling use. |
| 48 | It reduces the need to burn fossil fuels and lowers pollution and resource use. |
| 49 | The Sun powers photosynthesis, which helps plants grow and supports food chains. |
| 50 | Example: In the water cycle, solar energy heats water, causing evaporation; the water vapor rises, cools, and later falls as precipitation. |
