Investigation 8

Question 1

Atmospheric (air) Pressure

Answer 1

The amount of pressure in the atmosphere

Question 2

Isobars

Answer 2

Lines of equal pressure on a pressure map

Question 3

Wind

Answer 3

The movement of air from high to low pressure

Question 4

Pressure and Temperature relationship

Answer 4

High pressure = nicer weather

Question 5

Pressure and Volume relationship

Answer 5

Increase pressure = increase volume

Question 6

Pressure and Density relationship

Answer 6

Increase pressure = increase density

Question 7

Wind Flows

Answer 7

High to Low pressure

Question 8

Isobar Distance

Answer 8

Change in pressure

Question 9

Wind Forms

Answer 9

• air is heated by he ground
• air warms and rises because it is less dense; that creates a low pressure area
• the warm air spreads out and cools
• the cool air sinks because it is more dense; that creates a high pressure area
• wind flows from high to low pressure, the the high pressure area flows to the low pressure area creating wind
