Heat Transfer.
Radiation – the transfer of energy through space. Heat transfer by radiation takes place with no direct contact between a heat source and an object. Example.
Energy transfer. Climatic Interactions The sun provides and transfers currents of energy over the earth surface. RAYS of energy Are the Sun’s rays Heating.

Heat Movement. Golden Rule of Heat Movement The golden rule is… Heat always moves from a warmer object to a cooler object. You can think of it like water,
 Heat always flows from places of high heat to areas of lower heat.
1.3 notes  There are 3 types of heat transfer: radiation, conduction, and convection.  The transfer of energy through space is radiation. Sunlight.
Types of HEAT Energy Transfers CONDUCTION Objects are in direct contact. Heat energy transfers when particles collide or objects in contact are TOUCHING.
Heat Energy. What is Heat Energy? Heat Energy Heat Energy is the sum total of all of the energy of the particles of an object. Heat energytemperature.

Presentation transcript:

Energy Flow in the Earth System

Weather: movement of air and water in the atmosphere Oceans: movement of water by ocean currents Life: energy that sustains plants, animals, and all life on Earth Tectonics: movement of earth in the crust, causing earthquakes, volcanoes, and continental drift

Energy Flow All life, all of the Earth’s processes (tectonics, weather, life) exist due to the flow of energy through the Earth System Two sources of energy The Sun and the Earth’s Core

Heat Transfer how heat moves Conduction: heat transfer between substances in direct contact (touching) Convection: heat transfer by movement of gases or liquids (fluids) Radiation: heat transfer by EM waves (electromagnetic) traveling through space
