Answer 1

troposphere

Question 2

The belt of high pressure that appears over the Australian continent during the winter months is called …..

Answer 2

the sub tropical ridge

Question 2

the monsoonal trough features extensive cloud and weather because …..

Answer 2

it is in a region where converging airstreams ruse over warm ocean due to the intensity of solar radiation

warm

Question 8

Temperature drops by ….. degrees per ….. feet

Answer 8

2⁰ every 1000ft

When compared with the size of the earth, the troposphere is very thick/thin

Answer 9

thin

Question 10

Answer 10

TCU and CB only

Question 10

The ITCZ is …..

Answer 10

the region where the surface air flow from each hemisphere converges and rises

Question 11

There is very little convection in the stratosphere becuase …..

Answer 11

the air at the top of the layer is warmer than the air at the bottom

Question 12

The sub polar low occurs between …..

Answer 12

the polar cell and the mid-latitude cell

Question 12

Draw the vertical movement of air with your minds eye

Answer 12

Tropical Cell

Mid-Latitude Cell

Polar Cell

Question 13

Almost all of the convective wx occurs in the …..

Answer 13

Troposphere

Question 14

The height of the tropopause varies with …..

Answer 14

latitude

Question 16

Vertical movement of air:

Falling air ….. as it sinks and therefore tends to be …..

Answer 16

warms, free of wx

Question 17

In rising air surface pressure …..

Answer 17

falls

Question 18

The stratosphere is the region above the …..

Answer 18

troposphere and tropopause

Question 20

Temperatures at the ozone layer …..

Answer 20

increase

Question 21

The tropopause marks the …..

Answer 21

roof of the troposphere

Question 22

Equatorial trough = high/low pressure

Answer 22

low

Question 24

Migration occurs because …..

Answer 24

the equatorial trough moves further north in summer than it does south

Question 25

What are the temps doing in the stratosphere …..

Answer 25

they are constant and rising towards the ozone layer

Question 27

Vertical movement of air:

Rising air contains vast amounts of ….. ….. and this causes …..

Answer 27

water vapor, extensive wx

Question 28

Why is there no wx beyond the tropopause …..

Answer 28

because here the convective air no longer cools with height

Question 30

Vertical movement within the atmosphere becomes less vigorous above the height of the tropopause becuase …..

Answer 30

the environment no longer gets colder with increased height

Question 31

The stratosphere rises up to ….. to meet the ozone layer

Answer 31

50km

Question 32

What clouds are found in the stratosphere …..

Answer 32

only TCU and CB’s

Question 33

In falling air, surface pressure …..

Answer 33

increases

Question 34

The equitorial trough moves further north than it does south because …..

Answer 34

The mid summer surface tempreatires are higher at any given latitude in the northern hemispher because of the greater land mass

Question 35

The height of the troposphere in Australian latitudes is approximately …..

Answer 35

10km

Question 36

The troposphere rises from ….. to …..

Answer 36

8km to 18km
