PART I SUNS RADIATION AND HEATING OF THE ATMOSPHERE.
. Energy Transfer in the Atmosphere A. Students learn about the three different modes of heat transferconvection conduction radiationand how they are related to the Sun and life on our planet. In an energy transformation the object remains.
Most of the radiation that the Sun gives off is. Energy Transfer in the Atmosphere Radiation. A measure of the average kinetic energy of the atoms or molecules in a substance - Fahrenheit Celsius and Kelvin -273 C.
Every day enough energy strikes the United States to supply the nations energy needs for one and a half years. Majority of sunlight is visible light At Earths surface it is converted to thermal energy heat. Includes a student worksheet for data collection and graphing.
Refers to the transfer of energy between substances due to temperature differences - heat flow stops when temperatures are equal III. Energy from the sun is transferred through space and through the earths atmosphere to the earths surface. This energy flows into the Atmosphere and heats this system up It also heats up the Hydrosphere and the land surface of the Geosphere and fuels many processes in the Biosphere.
Describe how air moves and changes in convection currents in the atmosphere. Because of Earths tilt these factors also change with time of year. Heat is the transfer of thermal energy from one object to another Students often have misconceptions about cold and may say cold is transferred between objects.
Scientists divide Earths atmosphere into four main layers classified according to changes in temperature. Yorks Science - Home. Almost all water vapour in the atmosphere is found here.
Mechanisms of Energy Transfer. The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. CKSci_G4Energy_TG_APAnswerKeyindd 138 201118 414 PM TEACHER RESOURCES ANSWER KEY 139 AP 81 Investigating Energy Transfer Station 2.
Continues to heat the atmosphere. The Chapter Reviewworksheets cover all major vocabulary concepts and objectives of the chapter. Another 30 percent is used to evaporate water which is lifted into the atmosphere and produces rainfall.
Since this energy warms the earths surface and atmosphere some of it is or becomes heat energy. There are three types of mechanisms to transfer energy. As you rise up through the atmosphere air pressure and temperature change dramatically.
Energy Transfer in the Atmosphere. In this way the Earth maintains a stable average temperature and therefore a stable climate. Energy flow productivity and chemical cycling biogeochemical cycles Energy flows through ecosystems Matter cycles within them Physical laws govern energy flow and chemical cycling in ecosystems Conservation of Energy first law of thermodynamics Energy enters from solar radiation and is lost as heat.
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. Energy of radiant objects such as fire5 11.
In the previous Incoming Solar Radiation section you learned that 19 units of incoming solar radiation are absorbed by the atmosphere greenhouse gases and clouds and 111 units of infrared terrestrial radiation are absorbed by greenhouse. Students should note the evidence of energy transfer is the light shining on the chalk dust and wall. Earths Atmosphere Lesson 2.
Therefore this is where most weather takes place. Heat Transfers Energy Step 3- Students should note the heat energy is. There are three ways heat is.
This should give you an idea of where your students are in their understanding. Accept a range of answers. Energy from the Sun is the driver of many Earth System processes.
The heat source for our planet is the sun. Using 100 units of energy from the sun as a baseline the energy balance is as follows. About 15 percent of the radiant energy that reaches the earth is reflected back into space.
If someone were to touch a hot pan energy from the hot pan transfers to the persons hand thus burning the hand. The Earth acts like a greenhouse which traps radiation heat from the sunTF___T___ Honors. These processes can all occur at the same time on either a small or large scale.
Has shorter wavelengths than visible light and can cause sunburn and skin cancer. Energy of appliances such as stereos and computers10 3. The transfer of energy by electromagnetic waves Suns energy travels 148 million km in only 8 minutes Electromagnetic Spectrum.
It can then release this energy as a photon by relaxing back down to any of the available lower energy levels. Energy from the Sun 1. Most of the radiation that the Sun gives off is visible light.
Read the selection and answer the questions. Energy gains and losses are balanced not only at Earths surface but also in Earths atmosphere. Gases in our atmosphere that trap heat are methane oxygen.
Geology the Environment and the Universe Teaching Transparency WORKSHEET 28 TEACHING TRANSPARENCY Energy. Amount of incoming solar energy varies by latitude AND time of year. Depth of atmosphere light must penetrate.
Is the transfer of energy by electromagnetic waves. Chapter ReviewThese worksheets prepare students for the chapter test. Through a teacher demonstration using water heat and food coloring students see how convection moves the energy of the Sun from its core outwards.
Answers and objective correlations are provided in the Teacher Guide and Answers section. 8 Transparency Worksheet 28 Earth Science. Energy Heat and Temperature B.
Conduction is the transfer of heat through matter by molecular activity. 50 miles above sea level. Closest to Earths surface 8 km to 16 km thick Highest density layer because all other layers compress it.
The first part is a vocabulary review and the second part is a concept review. This layer contains chemicals which absorb energy from the sun. Earths atmosphere is made up of five layers.
Ecosystem dynamics involve two main processes. Layers of the Atmosphere Worksheet. At the top of the.
Differences in the amount of energy absorbed in different places set the Atmosphere and. Type of energy that is stored9 6. Type of potential energy of objects at a height13 2.
There is also a strong coupling found between the atmosphere and ocean. Solar energy and thermal energy from Earth keep air moving. Convection conduction and radiation.
Infer how the transfer of energy in the atmosphere would be different without convection. What are the characteristics of each layer. The Earths atmosphere traps the suns energy and due to certain gases and clouds some of the heat is trapped warming the earth.
Has longer waves than visible light and is felt as heat. Ultraviolet light has shorter wavelengths than visible light and can cause sunburn and skin. Energy is transferred in the atmosphere ocean and Earths interior system by three processes.
T4 Earths Atmosphere Lesson Outline for Teaching Lesson 2. This layer is often called the upper atmosphere Any person trav-. Cold is just where there is less thermal energy.
Yet this amount of energy is enormous. In an energy transfer the same type of energy moves to a ____ object9 1. Key Concepts What are the four main layers of the atmosphere.
Transfer its gained energy to that molecule The energy from the solar wind is absorbed by an electron in the atom or molecule causing it to excite to a higher energy level. Radiation is the transfer of energy by electromagnetic waves. Because Earth is a sphere these factors change with latitude.
