Unit 6 Part 1 Heat Transfer and Atmosphere
Question | Answer |
---|---|
Heat Transfer | This is how heat moves from one place to another. Heat always moves from something hot to something cooler, like when you touch a warm cup and feel the heat in your hand. |
Conduction | The way heat moves through touch, like a spoon getting hot in soup. |
Convection | The way heat moves through liquids and gases, like warm air rising and cool air sinking. |
Radiation | Heat traveling through space, like the Sun warming your face. |
Convection Currents | This happens when warm air or liquid rises, and cooler air or liquid sinks, creating a cycle. It’s like how hot soup moves around in a pot or how wind moves in the atmosphere. |
Electromagnetic Waves | These are invisible waves that carry energy, like sunlight, radio waves, or X-rays. You can feel the heat from the Sun even though there's empty space between the Earth and the Sun because of these waves. |
Radiant Energy | This is energy that travels in waves, like light or heat from the Sun, a fire, or a light bulb. You feel radiant energy when you stand near something warm. |
Greenhouse Gases | Gases like carbon dioxide and methane that trap heat in the atmosphere, keeping Earth warm. |
Atmosphere | The layer of air that surrounds Earth and protects us. |
Troposphere | The lowest layer of the atmosphere, where all weather happens. |
Stratosphere | A layer of the atmosphere where airplanes fly and the ozone layer is found. |
Ozone layer | A part of the atmosphere that protects us from the Sun’s harmful rays. |
Mesosphere | A layer of the atmosphere where meteors burn up, making shooting stars. |
Thermosphere | A very hot layer of the atmosphere where the northern lights happen. |
Exosphere | The very edge of our atmosphere; in this layer the air is extremely thin and separates the rest of the atmosphere from outer space. |
Air Pressure | The weight of the air pushing down on everything. |
