|
|
Term

|
Definition
Solar radiation - 50% is abosrded on earth, 20% is absorbed in clouds, 30% is reflected off clouds |
|
|
Term
Explain the difference between reflection and scattering. |
|
Definition
Reflection - rays bouncing off clouds, scattering - rays are moving in all directions |
|
|
Term
List the ways temperature can vary on earth. |
|
Definition
Land heats up pick quick and cools quickly, water heats up slowly and cools slowly, as you move up a mountain temperatures cool off, as you move up altitude temperatures cool down, clouds help lock in the temperatures at night and reflect off radiation during the day |
|
|
Term

|
Definition
Lands heat up quick and cools down quickly, water heats up slowly and cools slowly |
|
|
Term
What is albedo and how does it change from day to night ? |
|
Definition
Clouds help lock in the temperature at night and reflect off radiation during the day |
|
|
Term
How does altitude affect temperatures ? |
|
Definition
As you move up in altitude temperature cool down |
|
|
Term
Explain air pressure. What unit do we measure pressure ? |
|
Definition
Air pressure in a force exerted in all directions,millibars |
|
|
Term
What is barometer ? list the two types. |
|
Definition
Tool measuring air pressure, mercury and aneroid |
|
|
Term
|
Definition
Sun and pressure differences |
|
|
Term
Wind move from a ____ to ____ pressure systems. |
|
Definition
|
|
Term
Describe an isobar. What happens if they are closely spaced together? Far apart? |
|
Definition
Isobars are lines of equal pressure, closely spaced lines are low pressure and widely spaced lines are high pressure |
|
|
Term
Describe a high and low pressure system. Include weather conditions too. |
|
Definition
High pressure system - good weather (anti-cyclone moving clockwise),low pressure system - stormy weather (cyclone-clockwise) |
|
|
Term

|
Definition
|
|
Term
How does friction affect wind ? |
|
Definition

|
Definition
|
|
Term
Describe the movement of cyclones and anticyclones. |
|
Definition
|
|
Term
Describe the movement of trade winds, westerlies and polar easterlies. |
|
Definition
cyclones move counterclockwise, anti-cyclones move clockwise |
|
|
Term
Explain the differences between land and sea breezes. How are they different in the day as to the night ? |
|
Definition
trade winds move east to west, westerlies - move to west to east, polar easterlies move east to west |
|
|
Term
What instrument is used to determine the direction of the wind ? |
|
Definition
land breezes occur at night where wind moves from the land to sea, sea breezes occur during the day where wind moves from the sea to land |
|
|
Term
