33 Energy Transfer In The Atmosphere Worksheet Answers

Students should note the evidence of energy transfer is the light shining on the chalk dust and wall CKSciG4EnergyTGAPAnswerKeyindd 138 201118 414 PM TEACHER RESOURCES ANSWER KEY 139 AP 81 Investigating Energy Transfer – Station 2 Heat Transfers Energy Step 3- Students should note the heat energy is Energy Transfer in the Atmosphere A Energy from the Sun 1 is the transfer of energy by electromagnetic waves 2 Most of the radiation that the Sun gives off is 3 has shorter wavelengths than visible light and can cause sunburn and skin cancer 4 has longer waves than visible light and is felt as heat B Energy on Earth 1 Infer how the transfer of energy in the atmosphere would be different without convection 7 Describe how air moves and changes in convection currents in the atmosphere 8 Transparency Worksheet 28 Earth Science Geology the Environment and the Universe Teaching Transparency WORKSHEET 28 TEACHING TRANSPARENCY Instructions Read the selection and answer the questions The heat source for our planet is the sun Energy from the sun is transferred through space and through the earths atmosphere to the earths surface Since this energy warms the earths surface and atmosphere some of it is or becomes heat energy There are three ways heat is Chapter Twelve Earth’s Atmosphere Lesson 2 Energy Transfer in the Atmosphere Radiation the transfer of energy by electromagnetic waves Sun’s energy travels 148 million km in only 8 minutes Electromagnetic Spectrum Visible Light majority of sunlight is visible light At Earth’s surface it is converted to thermal energy heat Energy Transfer in the Atmosphere Multiple Choice Directions On the line before each question or statement write the letter of the correct answer —L 1 Most of the energy that reaches Earth from the Sun is A visible light B ultraviolet light C infrared radiation 2 When the Suns energy reaches Earth A most of it is absorbed by clouds 50 miles above sea level This layer contains chemicals which absorb energy from the sun Together the stratosphere and the mesosphere are often called the “middle atmosphere” The thermosphere lies above the mesosphere starting at about 50 miles above sea level This layer is often called the “upper atmosphere” Any person trav- a Atmosphere absorbed 19 b Land Water Absorbed 51 c Space clouds etc Reflected 30 30 Heat from the earth’s surfaces heats up the atmosphere What transfer process is this Radiation causes the earth’s surface to heat up Once heat is released then convection process continues to heat the atmosphere 31 That is if Q is the heat transferred from the surroundings to the system then Q 0 means that net heat is transferred to the system so as to increase the energy of the system If Q 0 then net heat is transferred from the system to the surroundings and the system has lost energy Note that Q has units of energy eg J BTU cal Chapter ReviewThese worksheets prepare students for the chapter test The Chapter Reviewworksheets cover all major vocabulary concepts and objectives of the chapter The first part is a vocabulary review and the second part is a concept review Answers and objective correlations are provided in the Teacher Guide and Answers section
