Presentation transcript:

Quiz Name the first four layers of the atmosphere in order from the ground up. (4pts) 2. List four atmosphere gases. (4pts) 3. List two types of particulate matter. (2pts) 4. Extra Credit (2pts) From the in-class model list the types of candy in order from starting from the surface of the Earth.

What is the Function of the Atmosphere? Acts as a filter; absorbs and reflects solar energy Transfers Thermal Energy

Solar Energy = Visible light, infrared and UV waves FILTERS Incoming & Outgoing Solar Energy = Visible light, infrared and UV waves Reflects = Bounces off Absorbs = Soaked up

Transfer of Thermal Energy What is Thermal Energy? The total energy of the particles in an object due to their random motion (vibration). What is Heat? Transfer of thermal energy from a region of higher temperature to a region of lower temperature

Thermal energy can be transferred in three ways Radiation = transfer of Thermal Energy by electromagnetic waves. Transfer directly from the Sun to Earth’s surface. Electromagnetic waves are both Visible and Infrared waves Examples: Sunburn & Heat Lamps

2. Conduction = transfer of thermal energy through an object from a higher to a lower temperature. Transfer between the Earth’s surface and Troposphere. Example: a spoon in a cup of hot soup becomes warm because the heat from the soup is conducted along the spoon.

3. Convection = transfer of thermal energy by the movement of the heated material. Occurs between liquids & gases, main mechanism for energy transfer in the atmosphere Example: water current inside a boiling pot

DEMONSTRATION A visual representation of thermal energy transfer. ***Remember*** Thermal energy can be measured Heat is what we feel.

Quick Tip.. Radiation Heat transfer from a light source. Conduction Heat transfer through a solid . Convection Heat transfer through a liquid or gas.
