Investigation 5

Question 1

Convection

Answer 1

When a mass of a fluid, liquid, or gas, is warmer or colder than the surrounding fluid, he mass will rise or sink

Question 2

Convection Cell

Answer 2

Mass of fluid flowing in a circle

Question 3

Density

Answer 3

How heavy an object’s mass is

Question 4

Mass

Answer 4

The amount of matter in an object

Question 5

Volume

Answer 5

The amount of space the object takes up

Question 6

Density Equation

Answer 6

D=M/V

Question 7

Density and Temperature relationship

Answer 7

The warmer the temperature the less dense and vice versa

Question 8

Convection Cells in the Atmosphere

Answer 8

• Sun heats the ground by radiation
• the ground radiates energy to the carbon dioxide and water vapor in the atmosphere
• air in contact with the ground absorbs energy by conduction
• warm air rises because it is less dense
• as the warm air rises it cools, becomes more dense and sinks
• reheats by conduction and re-radiation starting the convection cycle once again
