Q

How does cumulus clouds form?

A

They are form due to the movement of air. The warm air from the ground begins to rise. As the air rises, the temperature drops causing humidity to rise.

39
Q

Changes in the air temperature are caused by the energy from the ______.

A

sun

40
Q

It carries heat energy.

A

sunlight

41
Q

True or False: As the sun heats up Earth, the air surrounding Earth gets heated, too?

A

True

42
Q

True or False: Air molecules rise when heated and sink when cooled. Warm air and cold air continuously circulate and move due to the difference in the temperature.

A

True

43
Q

True or False: The part of Earth that faces the sun and receives sunlight experiences daytime and gets warm. On the other hand, the part of Earth hidden from the sun experiences nighttime.

A

True

44
Q

Is it true that air temperature varies from sunrise to sunset?

A

True

45
Q

Is it also true that the duration of daytime varies?

A

True

46
Q

Is a moving air, it is formed as a result of the unequal heating of Earth.

A

Wind

47
Q

They study the speed and direction of the wind to forecast weather.

A

Meteorologists

48
Q

It describes how fast a wind blows.

A

wind speed

49
Q

It refers to the direction where wind comes from.

A

wind direction

50
Q

It is an instrument that describes wind speed based mainly on observed sea conditions. The instrument is divided into 13 levels, from the calm wind of force 0 to typhoon wind of force.

A

Beaufort scale

51
Q

Wind speed is measured with a unit of _________.

A

miles per hour (mph)

52
Q

The Beaufort scale was developed in 1805 by?

A

Sir Francis Beaufort

53
Q

True or False: Wind are named according to the direction from which the wind blows. When a wind blows from east to west, the wind is called an east wind.

A

True

54
Q

Is the amount of water vapor or moisture in the air.

A

Humidity

55
Q

True or False: Humidity changes from time to time and from place to place.

A

True

56
Q

True or False: Humidity changes as temperature changes.

A

True

57
Q

True or False: An increase in temperature causes faster evaporation.

A

True

58
Q

True or False: If the humidity is high, more water may be used to make clouds. The greater the amount of water, the more clouds are formed.

A

True

59
Q

What are the important elements included in a typical weather report?

A

chance of rain
wind speed (kph)
wind direction
temperature (degree celsius)
cloud cover
rainfall (mm)

60
Q

Weather reports and forecast can be recorded in a _________.

A

weather chart.

61
Q

Is a weather instruments that are used to measure temperature.

A

Thermometers

62
Q

Weather stations use an ordinary thermometer that has a liquid inside. Some use an ________. It has a sensor that measures the high and low temperatures.

A

electronic maximum-minimum temperature sensor (MMTS) system.

63
Q

True or False: A thermometer has a distinct parts. It has a glass rod with a thin tube in it. This tube has a liquid inside. A bulb is found at the base.

A

True

64
Q

True or False: In a thermometer the numbers or scales are calibrations with units, which can be in degree Fahrenheit or in degree Celsius.

A

True

65
Q

This is the curve on top of the liquid in a thermometer.

A

meniscus

66
Q

Is used to determine wind direction. It has a pointer and a tail. The pointer directs where the wind is coming from. (north, east, west, and south)

A

wind vane.

67
Q

How do you measure air temperature using a thermometer?

A

Make sure that the thermometer is in a shaded place. When the air is hot, the liquid inside the glass rod expands. The expansion causes the liquid to rise within the tube. The liquid inside the thermometer contracts when the temperature is low. To read the temperature, follow the meniscus of the liquid.

68
Q

Is a weather instrument that is used to measure humidity or the moisture in the air.

A

hygrometer

69
Q

Is a weather instrument that measures wind speed. It has three cups fixed to a mobile shaft. As the wind blows faster the cups spin around faster. The shaft is connected to a device that gives the wind speed in kilometers per hour. The anemometer counts the number of rotations the cups do to calculate the wind speed.

A

anemometer

70
Q

Is a weather instrument that measures the amount of rainfall in millimeters. Sometimes, it is calibrated in centimeters or inches.

A

rain gauge

71
Q

This weather instrument is placed in an open space to collect rain. It is composed of a funnel, a measuring tube, and an overflowing tube.

A

rain gauge

72
Q

True or False: The interaction of the different weather elements bring about different kinds of weather.

A

True

73
Q

True or False: Sunny day can be a fine or fair.

A

True.

74
Q

How do you define a fine weather?

A

It is characterized by a clear, blue sky. The sun shines brightly all day long. Weather forecasters predict 0% precipitation or chance of rain, so occurrence of rain is not likely to happen.

75
Q

How do you describe a cloudy weather?

A

When the sky is covered with different clouds. Since the sky is covered with clouds, isolated rains could occur depending on the type of clouds. However, not all clouds bring rain. This depends on the shape or combination of shapes the clouds have.

76
Q

How do you describe a rainy weather?

A

During a rainy weather, precipitation falls almost the whole time. You wear rain boots and coats. You also bring umbrella to protect yourself from getting wet.

77
Q

How do you describe a stormy weather?

A

Stormy weather happens when there are heavy rains and strong winds. Listening to typhoon warnings and advisories is important for information and safety.

78
Q

True or False: Weather affects the following: choice of clothes, choice of food, activity, occupation and livelihood, and health.
