Because the Sun heats the. Students will learn that most of the energy on Earth originates from the sun. Climate and Energy P607 lecture 5.
Checking In questions are intended to keep you focused on key concepts. The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. Earths albedo is a measure of how strongly the earths surface reflects the suns energy.
Then they will explore Earths Energy Budget through a video. Water Lab In addition there is a general capture sheet GPM Global Energy Budget Student Capture Sheet for all students to complete during the engage discussion of vocabulary and the summaries of the labs and discussion afterward. The energy created by this reaction is converted into thermal energy heat.
Smaller energy sources such as Earths internal heat are taken into consideration but make a tiny contribution compared to solar energy. Understanding the Earths energy budget can help to predict future effects of global warming and to understand the various flows of energy on the Earth. It is composed mainly of hydrogen and helium.
CERES website What does incoming and outgoing fluxes have to do with Earths energy budget. Removing Fossil Fuels from the Ground. They will complete a short lab investigating the effect of surface color type of material land or water or clouds on temperature change to begin to think about how Earths varying surfaces might affect overall temperature.
The rate of flow of energy across a given surface 3. Comments on previous overhead. Watch the NOVA PBS video – The Climate Wild Card about the different effects of clouds on climate and Earths energy budget.
Keeping Track of What You Learn In these pages youll find three kinds of questions. As you read use the information to balance the energy budget at Earths surface. Earths energy budget is a metaphor for the delicate equilibrium between energy received from the Sun versus energy radiated back out in to space.
NASAs The Clouds and the Earths Radiant Energy System CERES and NASAs. 4 rows Earths Energy Budget cutouts 1 set per group of 2-3 students Earths Energy Budget. The term earths energy budget was coined to refer to the energy the planet receives from the sun utilized all over the earth and then sends back into space.
The energy coming in to the Earth comes from the Sun and over the surface of the planet this incoming radiation has a rate of transport of. Method Notes Energy Budget INDIVIDUAL SEAT WORK OR PAIR WORK See 211 Bell Work Teacher Guide for answers and explanations LECTUREPRESENTATION See 201 Definitions See 213 Energy Budget Slides 2-5 Use 214 Action Notes Changes for Next Time. About 30 percent of the suns incoming energy is reflected back to space by clouds atmospheric.
Energy Balance for Both Earths Surface and Atmosphere Read the following section and study the diagram. Earths energy budget refers to the tracking of how much energy is flowing into and out of the Earths climate where the energy is going and if the energy coming in balances with the energy going out. The energy budget of the Earth involves incoming solar energy outgoing amounts of energy and the amount of energy that stays in the atmosphere and how the energy flows from one place to another.
List the major greenhouse gases and their role in Earths energy balance. Nuclear 83 Oil 394 Coal 227 Natural gas 236 Hydroelectric 27 Biomass 28 Geothermal wind solar and other 05. Energy from the sun is mostly in the visible portion of.
31 of the incoming solar radiation is reflected or scattered back to space the ALBEDO 235 Wm-2warms the Earth and atmosphere 168 Wm-2of which warms the surface. 124CHAPTER 5Earths Energy and Mineral Resources. Describe the role of the water cycle in maintaining Earths energy budget.
Teacher guides students through updating their Earths energy budget model worksheet to include information about changes to the amount of shortwave and longwave energy coming and going from the Arctic over the past 2 decades 2000-2018The teacher should update the class model under a document camera see Answer Key for example. The Earths Radiation Budget Part I. At the top of the.
When visible radiation from the Sun reaches the Earth and the sky is clear some of it is reflected or scattered directly back into space as shortwave radiation the percent reflected is known as albedo and some of. Students use a combination of computer animations readings and a hands-on lab as they deepen their understanding of Earths water cycle and how it relates to the Earths energy balance. To balance the energy budget write the units of energy gained or lost for each process in the table.
Energy Budget Introduction – Discuss the terms energy budget and equilibrium. As you learned from the reading the balance between incoming energy from the sun and outgoing energy from Earth ultimately drives our climate. This lab can be completed offline.
Earths systems are often described in terms of budgets. The Global Energy Budget. Then answer questions and brainstorm to complete a flow chart of events that might occur if the percentage of absorbing clouds increases.
In this way the Earth maintains a stable average temperature and therefore a stable climate. An answer key is. The sun provides all the energy that is utilized within the earth although most of the suns energy.
They will also learn what happens to the energy once it reaches Earths atmosphere. Teachers can print out the lab instructions to share with the class. Coal is removed from the ground using one of several meth- ods of excavation.
In the Suns interior a thermonuclear fusion reaction converts the hydrogen into helium releasing huge amounts of energy. The energy budget also accounts for how energy moves through the climate system. Using 100 units of energy from the sun as a baseline the energy balance is as follows.
There are many different ways to represent the energy balance of the Earth using diagrams.
