Answer 4

Digital Thermometer

Question 5

Where is A thermometer Placed?

Answer 5

Stevenson’s Screen

Question 6

What is the measurement unit of precipitation

Answer 6

Mm

Question 7

Instruments used to measure precipitation

Answer 7

Rain Gauge

Question 8

Where should you place Rain Gauge

Answer 8

Not near obstacles(trees/ buildings)
So it doesn’t stop rain or channel extra rain into the data

Question 9

How does Rain Gauge Work

Answer 9

Rainfall is collected into the funnel and the collecting jar

Jar is emptied once a day

Is measured using measuring cylinder

Question 10

Measuring instrument of Wind Speed

Answer 10

Anemometer

Question 11

Measuring unit for Wind Speed

Answer 11

Km/h

Question 12

How does Anemometer work

Answer 12

3 cups are mounted on a high ground which rotates as the wind blows. Wind speed is recorded on a dial and is displayed in km/h

Question 13

Where is an anemometer placed

Answer 13

Attached to the top of the building

Question 14

Measuring unit of Air Pressure

Answer 14

Millibars

Question 15

Measuring instrument for air pressure

Answer 15

Barometer

Question 16

Explain Barometer

Answer 16

It consists of an aneroid cell which contains a metal capsule with vacuum
As the air pressure increases the cell contracts
As the air pressure decreases the cell expands
This moves the dial and shows pressure in millibars

Question 17

Where can barometers be placed

Answer 17

Anywhere

Question 18

How does Wind vane work

Answer 18

The top section is loose and moves with wind while the base is fixed The arrow points to the direction where the wind is coming from

Question 19

Where is Wind vane Located

Answer 19

Top of a Building

Answer 20

Cirrus
Cumulonimbus
Cumulus
Stratus

Question 21

Characteristics of Stevenson Screen

Answer 21

1) Painted White( Reflect Sunlight)
2) Legs( Ensure it is in air and not ground)
3) Slates( air flow)

Question 22

Why is weather forecasting not always accurate?

Answer 22

Due to the chaotic nature of our atmosphere, it is hard to give accurate long range forecast

Question 23

Factors Affecting Climate

Answer 23

Latitude
Altitude
Prevailing Winds
Distance from the sea

Question 24

How does latitude affect Climate

Answer 24

The sun’s rays to the equator travels a shorter distance and there is a smaller chance that is will be reflected by clouds.
However, the sun rays take a long time to reach places with a high latitude as it has to travel more distance

Question 25

Explain How Prevailing winds affect the temperature

Answer 25

The temperature and moisture characteristics of prevailing winds will be affected by where it comes from

Question 26

Where does the UK's winds come from

Answer 26

North Atlantic drift South West

Question 27

Explain how distance from the sea affects Climate

Answer 27

The water in the sea takes longer to heat up but takes longer to slow down. In the winter, the water still holds the heat from summer In the summer , the water still holds its cool from the winter This means that the coastal areas are cooled by the sea in summer and are warmed by the sea in winter

Question 28

What are satellites

Answer 28

Small spacecrafts which carry weather instruments

Question 29

Polar Satellites

Answer 29

Rotates the whole earth in 24 hours

Question 30

Geostationary Satelites

Answer 30

Stay over the same place

Question 31

Measurement unit of Clouds

Answer 31

Oktas

Question 32

How do you observe clouds cover?

Answer 32

By looking at the sky

Question 33

Explain Land Base Station(3 key points)

Answer 33

10000 world wide Take readings every 3 hours Example- stevenson screen

Question 34

Explain how Rainfall Radar Works

Answer 34

Transmitter sends out harmless microwaves receiver picks up reflected waves

Question 35

Explain Buoys

Answer 35

fixed/drifting in the sea use digital instruments to record the weather and transmit the information into computer

Question 36

Explain Rainfall Radars

Answer 36

use electromagnetic waves to measure where rain in happening and how heavy the rain is

Question 37

What is Latitude

Answer 37

Latitude means how far north or south of the equator a place is

Question 38

What is Altitude?

Answer 38

Altitude is how high the land is above sea level

Question 39

Explain How does Altitude affect sea level

Answer 39

The temperature drop 0.6 degree Celsius for every 100 meters above sea level. This is because the sun heats the ground and ground heats the air. As you of higher, there is less ground to heat the air
