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. These guides outline the essential principles and fundamental concepts needed to be ocean and climate literate. They allow you to check if the.
A More energy flows to the planet than away from it. Energy Balance for Both Earths Surface and Atmosphere Read the following section and study the diagram. Students may want to use colored pencils to copy.
Smaller energy sources such as Earths internal heat are taken into consideration but make a tiny contribution compared to solar energy. In the Suns interior a thermonuclear fusion reaction converts the hydrogen into helium releasing huge amounts of energy. 31 of the incoming solar radiation is reflected or scattered back to space the ALBEDO 235 Wm-2 warms the Earth and atmosphere 168 Wm-2 of which warms the surface.
In the following investigation you will learn about Earths energy budget and the processes that balance the incoming solar radiation and the outgoing terrestrial radiation. EARTHS HEAT BUDGET The Sun is the star located at the center of our planetary system. There are many different ways to represent the energy balance of the Earth using diagrams.
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. Climate and Energy P607 lecture 5 The Global Energy Budget Comments on previous overhead. To balance the energy budget write the units of energy gained or lost for each process in the table.
Students learn about the energy inputs and outputs that. Describe the role of the water cycle in maintaining Earths energy budget. Earths energy budget is vital in establishing the Earths climate.
The energy budget also accounts for how energy moves through the climate system. 235 Wm-2 corresponds to a black body temperature of -19 C thermal emission at 10 um. 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.
Formal 6 - 8. For the energy budget at Earths surface to balance processes on the ground must get rid of the 48 percent of incoming solar energy that the ocean and land surfaces absorb. It is composed mainly of hydrogen and helium.
Surface Energy Budget To understand how the Earths climate system balances the energy budget we have to consider processes occurring at the three levels. 2 the edge of Earths atmosphere where sunlight enters the system. Answer Key for Planetary Energy Balance Assessment Questions 1.
A national program providing resources to educators so they can build scientifically-literate communities and engage in stewardship activities in response to environmental challenges. 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. Energy leaves the surface through three processes.
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. 8 surface 69 absorption20 clouds 49 surface Reflection is frequency dependent but will be treated as average value for visible light range. Earths energy budget describes the balance between the radiant energy that reaches Earth from the sun and the energy that flows from Earth back out to space.
An answer key is. In the simplest terms possible what is Earths energy budget. This lab can be completed offline.
Evaporation convection and emission of thermal infrared energy. 1 the surface of the Earth where most solar heating takes place. The energy created by this reaction is converted into thermal energy heat.
Checking In questions are intended to keep you focused on key concepts. Teachers can print out the lab instructions to share with the class. Energy budget albedo reflection absorption radiation unequal heating.
In this lesson students will explore through labs videos and a simulation how energy from the sun is absorbed reflected and radiated back out into space as part of the Earths energy budget. Earths energy budget accounts for the balance between the energy that Earth receives from the Sun and the energy the Earth radiates back into outer space. As you read use the information to balance the energy budget at Earths surface.
And 3 the atmosphere in between. When a planet is in a state of thermal equilibrium which of the following statements about energy flow is most accurate. To balance the absorbed incoming energy Earth must on average emit the same amount of radiation to space.
In Part A. Earths systems are often described in terms of budgets. B The flow of energy to the planet is about the same as the flow of energy away from the planet.
GPM Global Energy Budget Clouds Lab and GPM Global Energy Budget Land vs. Earth energy budget and balance Earth energy budget and balance 31 total reflection 23 clouds.
