PRECIPITATION PART 1

Question 1

is the general term for all forms of moisture emanating from the clouds and falling to the ground.

Answer 1

Precipitation

Question 2

This type of precipitation is in the form of local whirling thunderstorms and is typical of the tropics.

Answer 2

CONVECTIONAL PRECIPITATION

Question 3

The air close to the warm earth gets heated and rises due to its low density, cools adiabatically to form a

Answer 3

cauliflower shaped cloud

Question 4

cauliflower finally bursts into what?

Answer 4

thunderstorm

Question 5

When convectional precipitation accompanied by destructive winds, they are called?

Answer 5

tornados

Question 6

When two air masses due to contrasting temperatures
and densities clash with each other, condensation
and precipitation occur at the surface of contact.

Answer 6

FRONTAL PRECIPITATION

Question 7

condensation and precipitation occur at what surface of contact?

Answer 7

Front or Frontal Surface

Question 8

If a cold air mass drives out a warm air mass, it is called a

Answer 8

Cold Front

Question 9

If a warm air mass replaces the retreating cold air mass

Answer 9

Warm front

Question 10

If two air masses are drawn simultaneously towards a low- pressure area, the front developed is stationary and is called a

Answer 10

STATIONARY FRONT

Question 10

Cold fronts move faster than warm
fronts and usually overtake them,
the frontal surfaces of cold and
warm air sliding against each other.

Answer 10

OCCLUDED FRONT

Question 11

the frontal surfaces of cold and
warm air sliding against each other, this phenomena is called?

Answer 11

Occlusion

Question 12

This type of precipitation is caused by the uplift of moist air as it flows over a mountain or other elevated terrain.

As the air rises, it cool and condenses, forming clouds and precipitation.

Answer 12

OROGRAPHIC PRECIPITAION

Question 12

This type of precipitation is due to lifting of moist air converging into a low-pressure belt, due to pressure differences created by the unequal heating of the earth’s surface.

Answer 12

CYCLONIC PRECIPITATION

Question 13

Here the winds blow spirally inward counterclockwise in the

Answer 13

northern hemisphere

Question 14

Here the winds blow spirally inward clockwise in the

Answer 14

southern hemisphere

Question 15

comparatively small diameter of 300-1500 km
causing high wind velocity and heavy precipitation,

Answer 15

tropical cyclone (also called hurricane or typhoon)

Question 16

of large diameter up to 3000 km causing widespread frontal type precipitation.

Answer 16

extra tropical cyclone
