Q

What is a climograph

A

It is a single graph that charts both the average temperature and precipitation of a given location through the course of the year using separate axes for each variable.

Relative humidity
clouds
26
Q

name 6 weather elements

A
Temperature
Wind speed
Precipitation (rainfall/snowfall)
Air pressure
humidity
cloud cover
27
Q

what is the definition for wind

A

Movement of air from high to low pressure area

28
Q

what is the definition for precipitation / rainfall

A

Water that falls to from atmosphere to surface

29
Q

What is the definition for air pressure

A

Force exerted on earth’s surface due to air

30
Q

What is the definition for relative humidity

A

Amount of water vapor in the air

31
Q

What is the definition for clouds

A

Evaporated water vapor in air

32
Q

Name the measuring instrument for Temperature

A

Thermometer

33
Q

Name the measuring instrument for Wind

A

Anemometer

Wind vane/rose

34
Q

Name the measuring instrument for Precipitation/Rainfall

A

Rain Gauge

35
Q

Name the measuring instrument for Air pressure

A

Barometer

36
Q

Name the measuring instrument for Relative humidity

A

hygrometer
Sling psychrometer
wet and dry bulb

37
Q

Name the measuring instrument for clouds

A

there is none

38
Q

In which Unit is temperature measured

A

degrees Celsius

39
Q

In which unit is humidity measured

A

percentage

40
Q

In which unit is rain/precipitation measured

A

millimetres

41
Q

In which unit is wind measured

A

km/h

kilometre per hour

42
Q

In which unit is atmospheric pressure measured

A

hectopascals

hPa

43
Q

What is evaporation

A

When a liquid turn into a gas or vapor we call this evaporation

44
Q

What process is evaporation

A

It is a cooling process

45
Q

What is condensation

A

The process in which water vapor turns into liquid

46
Q

What is the water in the air called

A

a gas known as water vapor

47
Q

What is dew Dew Point

A

temperature to which air must cool for condensation to occur

48
Q

What is saturation

A

It is the condition where the air is completely full of water vapor

49
Q

What is the difference between evaporation and condensation

A

In condensation the water cools and falls to the ground. And in evaporation the water is heated and then tuns into water vapor

50
Q

What is the difference between dew point and saturation

A

Dew Point: the temperature must cool before condensation happen. And Saturation is when the air is filled with water vapor

51
Q

How does frost occur

A

Frost occurs when water vapor turns directly into ice crystals on objects near to the ground

52
Q

How can frost damage many kinds of plants

A

The fluid inside plant cells expands as they freeze. This cause the cell walls to break.
Frost is tiny bits of ice that fall on a plant and damage the stem or the plant can freeze and die.

53
Q

Name the PROCESS where liquid changes into a gas

A

Evaporation

54
Q

Why does the Sahara Desert have very little evaporation

A

Because there is very little water

55
Q

When does dew and frost form

A

There have to be enough water vapor and low temparatures

56
Q

What prevent dew and frost to form

A

Clouds and a change in air pressure

57
Q

What is the water cycle

A

The water cycle is a pattern of changes in the form of water

58
Q

Describe the water cycle

A

water evaporates from the surface of the earth
rises into the atmosphere
cools and condenses into rain or snow in clouds
falls again to the surface as precipitation/rainfall

59
Q

Clouds in the atmosphere forms because

A

the water vapor freezes
